Finally, a decent Dyno

[futureroadracer]

Hey guys,

I figured I would post my recent dyno results. Since December I have had numerous dyno pulls and never saw a real increase in power. Needless to say I have been very disappointed until today. My first dyno pull was with 19psi, SS reps and TRM tune. The car made 449whp on a dyno dynamics. While decent, it was still low for my mods. TRM has been great revising the tunes for me but never saw any gains. The next 4-5 dyno pulls all resulted in similar numbers, 433, 438, 443, 447 and 451 whp, this was even after I upgraded to the RMS headers. Still nowhere near the power I was hoping for.

I finally called TRM and spoke with Mike McCoy, I asked him to really push the limits with the tune. He did and the car picked up 8-20whp throughout the powerband but peak power was still pretty low at 452whp. So once again I was bummed...

After very informative conversation with Mike, he convinced me I had a restriction somewhere... We discusses possible problem areas but I have all the big, high flowing parts- I have a T-trim, ported head, cams and RMS headers etc, so we thought maybe the cams were out of time. I checked and much to my surprise, they were spot on. So once again, I was disappointed.

I finally sat and really thought about it... the only part on the car that is known for giving problems on S/C'ed cars is the BBTB, so I took it off. Once I did, I had the wife press the accelerator and there it was.... the throttle is only opening 85-90% of the way. I couldn't believe it. I adjusted the cable and went to my buddies shop. He has a brand new 2wd dyno dynamics dyno, as soon as he started making a pull I knew it was going to make more power. The car made 476.1whp on the first pull and 477.2whp on the second, so needless to say, I am excited!

My set up is:
e30
S50/ .140
Bavarian Solutions head
Schrick cams
RMS headers (dual 2.5", 2 cats, 2 mufflers)
RMS aftercooler
BBTB
Vortec T-trim (6.75" cranks pulley, 2.95 blower pulley. Seeing 18-19psi@7200)

I will scan and post a few of the dynos this weekend.

Good stuff. So, is it done per say?

I'm gonna check my TB!

[Colby Colbs]

So is this the same setup as daves old setup when he broke 500rwhp?

Cuz as far as I can see there's still some hidden powa!

Dave had a 3.2 as well as a Dynojet.

[Colby Colbs]

a magical dynojet?
Soo what stage head? Whos cams?

Did dave have head work? cams? the new bavsol heads are flowing more than ever and matched with a set of their billet supercharger cams noticeable gains should be had...

[m3jasper]

That's some decent power! Plan on getting a custom dyno tune? Any chance you can get it on a Dynojet?

Mine was a bit different, I had a stock head, 3.2L, custom OBD2 Nick G tune, and full Supersprint Euro exhaust with the cat delete.

I also feel there might be a bit of power left on the table hence the question about getting it on a Dynojet to see the dynosheets and comparing the runfiles to my 500rwhp setup.

My head was stock along with a set of Schrick cams. Ryan's head flows well so it would most definitely benefit from a set of cams.

He has a hand ported head that was used for developmental purposes. It flows the same as a stage 3. I'm truly curious as to what a set of our new billet camshafts would do for the setup...

It's nice to see my old car. Last time I had it on a Dynojet it made 401whp on the stock s50 motor. Nice gains. Do you have any pictures of it? Did you get it painted? I am in Kuwait now. When is your next deployment?

[futureroadracer]

The two dynos in my area read similar, I am sure my numbers would be very close on the dynojet. Regardless I am pretty happy now. I do plan on getting her on TRMs dyno so Mike can tune the car in person, I believe he will be able to make further, meaningful adjustments when he can monitor knock, IAT's etc.

After looking at the run files, I think there maybe a bit more power between 4250 and 6500. The tune is commanding 11.0's currently, which, a SC car probably doesn't need since the car is only seeing 8-14psi between 4250-6k. If we lean that out she may make a bit more through the RPM's which should help midrange. I am confident Mike can massage a few more WHP up top as well, but I think I will find substantial gains when I remove the cats and middle muffler. I plan on having a track pipe made soon, hopefully in the next few weeks so we shall see. I am hoping for 10-15whp gain from the trackpipe alone...

That said, now that we found the "restriction" I can swap on a smaller pulley and try to make 22-23lbs. I am confident I will be a good bit over 500whp when it is all said and done. (hopefully anyways)

Keep in mind, I am running a 3.0L, a 3.0L with 115k miles. I am sure a bit more displacement would result in slightly more power.

The main reason for this thread was to discuss the throttle body. On my dyno runs you could see the power flat-line up top, if any of you have a flat-lining dyno curve I highly recommend you make sure you TB is opening all the way.

Now I have a question... Is there a larger TB option for the S50? I have a BBTB but would like to install a bigger one. I picked up 25whp when I removed a small restriction, I imagine I could pick up a few more whp with a larger TB. Thoughts?

OH, FYI- I am seeing 110-115* IATs spinning the T-trim to 56k.

Ryan

[liilpa09]

nicely done! I'm very surprised you didn't have the similar results as I had when you put the RMS headers on from the US supersprint spec headers...maybe its because you got rid of the 3" exhaust? Are you running standard dual piping sizes now for the exhaust? Or did you get the euro supersprint parts? I know pbonsalb is selling his so it may be perfect for you if you haven't....

As far as throttle bodies, my Dinan one works great. I think they make one for the S50 as well and people haven't had issues with them like they have with the Riot Racing one and supercharged applicatiions.
good luck!

[futureroadracer]

I did have the gains, they just weren't realized until the TB was adjusted. I made 445-449 with the SS reps. Then I made 452 with the RMS and a new tune. Once the TB was adjusted I picked up the 25whp from the headers/ tune.

My current exhaust consist of the RMS headers, Dual 2.5" piping to 2 magnaflow hi flow cats, one 18" dual in/dual out magnaflow x-pipe middle muffler to a dual in/ dual out 22" magnaflow x pipe muffler in the rear. The car sounds bad-ass, its still a bit loud for my liking but the turbo will surely fix that... :evil2

I currently have a bored TB. It works flawlessly. My questions was about adding a larger one. If I picked up 25whp from maximizing my current TB, maybe I could pick up a bit more if I went with a larger 540i TB or something...

I did get it painted. I pulled the fenders, smoothed the antenna hole, removed the rear spoiler, removed the rear tow hook and removed the fogs. I added IS spoiler massive BBK, ground control coils, wheels etc.etc. etc.

I am trying to upload pics and the dyno runs but I keep getting an error.

That's my exact feeling. It's always better to tune a car in person.

Freeing up the exhaust will definitely help.

[black bnr32]

What was ambient temp and what did you do for your heat exchanger and pump? What size is the TB compared to the inlet/exit of the aftercooler? What size are your cats?

[futureroadracer]

Ambient temp last week was 95*, yesterday was 88-90*, both days and 6 dyno pulls yielded IAT's NO higher than 115*. This was 4th gear, on the dyno and recorded after each full power pull.

I am using a small 20x6" heat exchanger, a new ford lightening Bosch pump + pre and post compressor water injection....

I will have to measure the aftercooler/ TB.

I am running 2 magnaflow high flow cats, part # 59956

[ramsing]

hey Ryan...things are looking up, getting closer to the magic 500s....

[black bnr32]

Ah, forgot about the water injection. Good to see the IATs in line!

Ryan

How does one "BORE" the throttle body?
Disassemble it and take it to a machine shop?
How much "room" or material is there to remove.

I've heard of members here doing this
but I haven't seen a write up or whatnot.

Also,
can you post a shot of the "flat" graph you noted
so others might see the prospective throttle body door adjustment dyno differences.

[futureroadracer]

The TB is just bored and a new throttle plate added. I bought it from a guy on the forum but there are plenty of people on the web that can modify the TB. I think modifiying my manifold to accept a larger TB will be of benefit.

I have been trying all day to post two pics of the car and both dyno plots but i keep getting an error.... I can email them to you if you'd like.

What are you using to upload the images? I use imageshack.us/ make sure to resize them so they are not huge/small...

[futureroadracer]

Yeah the WI is working pretty well. I am running a shurflo 200psi pump, 1/4" tubing, a T-fitting and two nozzles. The pre-compressor nozzle is a 003 and the post is 010. I am using www.alcoholinjectionsystems.com progressive controller that has a built in MAP, which pulls a boost reference to control flow.

The controller has a start and full adjustment, I currently have the controller set to start around 11 and full at 22. Of course, I never see full flow. When I lower the the full psi dial, I pick up too much boost. For instance, when I have the full dial set on 18psi, I will see 21psi of boost at redline.

The pre-compressor injection cools the compressor and creates a more dense air charge, thus raising the compressors efficiency and boost pressure.

Once I am able to Mike tune it in person, I beleive we can maximize the WI and timing.



Ah, forgot about the water injection. Good to see the IATs in line!

The power/trq does seem a bit soft prior to 5250 rpm, but I've noticed that the SC'ed 3.0's seem to have curves like that. Just the other day a guy posted-up w/ an 11 psi TRM-tuned C38-81 S50 dyno and had a similar curve.

:nonoNo prolemno.

[futureroadracer]

I believe that has to do with the tune commanding 11.0's between 4-6k. I am sure another 10-20whp is possible between 4-6k if the tune is leaned out there.

Please run away from that Dyno Dynamics Dyno and get her on a Dynojet or Dynapack Dyno please.

What's the thinking behind that Cameron?

[ritoab]

What's the thinking behind that Cameron?
Dynamic generally reads lower in comparison.
For example on my 339rwhp Dynamic run reads 398rwhp on DynoJet
Use chart below
http://www.to4r.com/calcs/pwtq.php

[Ted B]

A Dyno-Dynamics dyno can be run in different modes (be advised). A Dynojet typically reads ~15% higher than a DD used in "Standard Mode" with a 'correction factor' of "1.0". Set the DD's correction factor to "1.15", and it will give figures comparable to a Dynojet when used in "Standard Mode".


FYI

[highboostingm3]

What's the thinking behind that Cameron?
1) With the two small rollers you have a alot of wheel spin issues with it that was a pain for me. My fab shop SFR has a DYno Dynamics and at 400whp the tires were spinning. No worries on Dynojet.
2) You can't run drag radials on it. My DRs were spitting rubber balls everywhere. You can on Dynojet...that's how I was able to do proper dynos without changing tires.
3) I hate the software and graphs compared to WinPEP. Let's face it, WinPEP is GOD for dyno software setups. Dyno Dynamics is run on MS-DOS I believe and simply a dinosaur.
4) It is not used often, the Dynojet is the most common. Therefore even though I know that temperature, Barometric pressure, etc. all make a difference we do like to compare dynos you can't deny that fact. So it's better to use a the common dyno to compare.
5) That brings me to the last point which works with the 3rd point. You can get run files for different dynos on WinPEP and overlay them even though the dynos were done 10,000 miles from one another. Can't deny the awesomeness of that!

[MrBlonde]

1) With the two small rollers you have a alot of wheel spin issues with it that was a pain for me. My fab shop SFR has a DYno Dynamics and at 400whp the tires were spinning. No worries on Dynojet.

Cameron if you're saying that a Dyno Dynamics machine can't dyno anything over 400 rwhp without the tires spinning then I can't agree (the max rating is 1,800 rwhp .. that's over 2,100 rwhp in Dynojet terms).
The effect I think you are commenting on is that Dynojet is inertia not load bearing. See more below.


2) You can't run drag radials on it. My DRs were spitting rubber balls everywhere. You can on Dynojet...that's how I was able to do proper dynos without changing tires.

You most certainly can run drag radials or even slicks on a DD machine just like any other chassis dyno. However it's better to run street radials where possible.
Again it's all about the load bearing and how effectively you strap the vehicle down. When there's no load on the rollers of course this is not an issue.

But stop to think what that means about tuning your car, rather than how easy it is to strap it down on the chassis dyno.


3) I hate the software and graphs compared to WinPEP. Let's face it, WinPEP is GOD for dyno software setups. Dyno Dynamics is run on MS-DOS I believe and simply a dinosaur.

I've got no comment on the dyno software and I couldn't care less. What I want out of a chassis dyno is to tune my car. Amateur tinkering with files .. for what purpose?


4) It is not used often, the Dynojet is the most common. Therefore even though I know that temperature, Barometric pressure, etc. all make a difference we do like to compare dynos you can't deny that fact. So it's better to use a the common dyno to compare.

For sure if what is important to you is the peak horsepower number than Dynojet is the way to go. Your car makes exactly the same power no matter what any dyno says, but if it makes you feel better then more power to ya!


5) That brings me to the last point which works with the 3rd point. You can get run files for different dynos on WinPEP and overlay them even though the dynos were done 10,000 miles from one another. Can't deny the awesomeness of that!

Comparing dynos with other people is of no interest to me nor I suspect any drag racers. The big black dyno tells me everything I need to know about how much power my car is making. A peak horsepower number is not important to people who race, their results are (like ET for drag racers or lap times for circuit racers). I guess if your car is a dyno queen then peak horsepower numbers are where it's at, but these cars are usually shit to drive on the street .. if they are ever really driven on the street at all.


The most important difference between Dynojet and DD is something you didn't touch on: load bearing. It's at the core of this discussion. DD is a better machine to tune your car. Dynojet gives pleasing numbers. You pays your money and you takes your chances I guess!



So where does the dynamometer come in? A load bearing dyno gives the calibrator the ability to hold the engine at one location while he refines the map of the surrounding area. Inertia only dynamometers freely accelerate as the engine makes more power. This makes it difficult to hold the engine steady at all the necessary map locations and build a detailed map. Load bearing dynos have the ability to hold the engine steadily in a much wider range or map locations in order to properly tune these areas. The more accurate these measurements can be at each point, the smoother the engine will run. So a dynamometer that can allow the tuner to make accurate measurements at each individual point on the map gives him the potential to make the engine run smoother in these areas as well. Keep in mind that this applies not only to fuel delivery, but the spark map as well. Finding MBT timing at part throttle requires instantaneous torque feedback at steady state that can only be done with a properly load controlled and instrumented dynamometer.

The added benefit to a load bearing dynamometer is that when it comes time to test dynamic conditions, the rate at which the engine sweeps across the RPM range can be adjusted to match exactly what happens in the real world. This means that the amount of time it takes to complete a run is the same between the track and the dyno. We have a better idea of just how much heat and load the engine will see on the street or track. In today's world of handheld flash tuning devices and "canned" tunes designed to fit a wide array of cars, testing under these real world conditions can make difference between "That should have been fine, I don't know why it broke at the track," and "Everything performed just like we expected" when the car comes off the dyno.

You do make good points of course Kenny and it's all pretty relative to what you want. I would much rather use the Dynapack Dyno for load tuning because it bolts to the hubs and therefore no worries with wheel spin (DavidM5 smartly used that dyno to tune his 800+whp car yesterday which made it easy because all he has are slicks). A load dyno is great for tuning I agree but I'd rather use a Dynapack if that is needed. Otherwise everything from your POV simply makes more sense to be on the big black dyno instead IMO. All the points I made are for people who do care about comparing dyno for dyno and want a universal type of dyno graph that they are used to understanding with easy software to compare with and work with. To someone who truly only cares about ET and TRAP, etc. the dyno isn't of much use other than the initial tune because it's a heck of a lot safer than tuning a race car on the street or even the track. To each his own, you made your point back in 2004 when most here were still poppin' zits and getting ready for the prom. :D

Oh and Brock Lesnar is the Baddest Man On The Planet!

Back on topic. Get thee to a Dynojet please so you can properly compare since dyno numbers are very relevant to you.

[futureroadracer]

It's not that dyno numbers are very relevant, it's the only way for me to measure power output currently. Luckily, I used the dyno to measure power, find a problem, troubleshoot and correct the issue which yielded 25whp increase.

If I never used the dyno, I would have never found the problem.


very relevant to you.

[futureroadracer]

UPDATE- TRM is sending me another tune, which will raise the rev limiter and lean up portions of the tune. Hopefully this picks up a bit more power, not sure if it will be enough to get me over the 500whp but we shall see.

I do have a question for you guys. What type of power gains are realized with the slightly larger displacement of the s52 motor when compared to the s50, meaning if you had identical engines with identical set ups, would the s52 make more power? If so, how much more? 5-10-20whp?

Thanks!

Definitely try a Dynojet this time.

Yes I understand how important dynos can be to see if you have a problem and to see if that problem is fixed and/or to see what an upgrade did for you. I am a believer.

S52 will make more torque and possibly a little more power.

[futureroadracer]

Nice! It will be interesting to see the power increase, if any, when we spin the S50 a bit more.

Ryan



S52 will make more torque and possibly a little more power.

[milKt]

How much more?

[futureroadracer]

Well, I picked up 30whp or so from 6500-7, I am hoping for 15-20whp more with the raised rev limit. The new tune should pick up a bit more power throughout in the mid-range as well.


How much more?

[futureroadracer]

The new TRM tune arrived and is now installed. I am not sure exactly what was changed but the car feels great! I would like to think the observed improvements are real but, it could just be in my head. The car feels much smoother and seems to have more midrange power.

I plan to revisit the dyno this coming week, also, I replaced the air filter. I doubt it will be a large gain but I am confident it will pick up some power. The old air filter had a large amount of overspray on it from the recent paint job, which couldn't have been helping air flow or power.

I have only gone WOT 1-2 times since I installed this new tune. It amazes me that even with the increased rev limit, the car feels like it wants to spin even more. It will be interesting to see the dyno results...

That's some decent power! Plan on getting a custom dyno tune? Any chance you can get it on a Dynojet?

Mine was a bit different, I had a stock head, 3.2L, custom OBD2 Nick G tune, and full Supersprint Euro exhaust with the cat delete.

I also feel there might be a bit of power left on the table hence the question about getting it on a Dynojet to see the dynosheets and comparing the runfiles to my 500rwhp setup.

My head was stock along with a set of Schrick cams. Ryan's head flows well so it would most definitely benefit from a set of cams.

He has a hand ported head that was used for developmental purposes. It flows the same as a stage 3. I'm truly curious as to what a set of our new billet camshafts would do for the setup...

They'll match his M54 regrinds really well! :D

BTW, Colby...your custom shims finally came in. :rolleyes You'll have the engine back by Friday.

Sorry for the OT, but I really respect what you are doing with the S62 over on M5Board. I knew I recognized those awesome pics!

I have only gone WOT 1-2 times since I installed this new tune. It amazes me that even with the increased rev limit, the car feels like it wants to spin even more. It will be interesting to see the dyno results...
Dynojet results...correct? :)

[m3jasper]

The new TRM tune arrived and is now installed. I am not sure exactly what was changed but the car feels great! I would like to think the observed improvements are real but, it could just be in my head. The car feels much smoother and seems to have more midrange power.

I plan to revisit the dyno this coming week, also, I replaced the air filter. I doubt it will be a large gain but I am confident it will pick up some power. The old air filter had a large amount of overspray on it from the recent paint job, which couldn't have been helping air flow or power.

Good to hear, hopefully you'll squeeze a bit more power out of her. I'm going to shoot you an email in the coming days to discuss getting a set of cams on the car so you can maximize the VE and get well over the 500rwhp hump.

Thanks. It's a great project to be a part of as Peter is a pleasure to deal with. Hopefully, we'll be making some noise with it in the very near future.

[futureroadracer]

Not sure yet. I may but, if I can use the dyno dynamics I will probably just use that as it is far cheaper for me.

Dave I will not be needing SC cams, but... I may need another set of turbo cams for the S52. I have been in contatc with Peter and I am very excited and jealous!

If it is only for you to compare the new tune to what you had before and see what exact gain you received, then definitely use the Dyno Dynamics.

When the time comes and you believe the car is how you want it, then go to a Dynojet to get your last numbers to properly compare to the rest of the US.

I know that members experiences have varied significantly with different dynos and that dynojets tend to give higher numbers than mustangs or dynodynamics. For whatever it is worth, here is a supposedly unbiased test an AWD turbo car on several different dynos on the same day:

That is a joke. Dyno Dynamics comes up higher than a Dynojet :lol

Here is the problem. The consistency between the dynos for which the operator can manipulate is jacked. There is none. Dyno Dynamics and Mustang can differ greatly depending on whether the operator wants to show high numbers or he doesn't know WTF he is doing calibrating his dyno or if it is calibrated perfectly without any "help". Way too many variables.

With Dynojet it is what it is and that is why it is the best if you are comparing to other cars across the country (not to mention WinPEP is SIIIIICK).

[Ted B]

If Dynojet has one good thing going for it (aside from its low price), it's the fact that a Dynojet cannot be manipulated by the operator. A DJ in Los Angeles will give the same reading as a DJ in London with the same car. This is not so with DDs and Mustangs, and IMO, their only downfall is that multiplier setting that creates so much confusion to those who either don't understand it or are unaware of its existence altogether.

[gstuning]

I guess you guys don´t know how to operate DD machines.

In shootout mode on the DD you can NOT manipulate the numbers. No way, No how.

That´s why the only chart you accept from the DD machine is the one with the green box on it showing the statistics used to arrive at whatever multiplication factor was used.

[Ted B]

I know, but for whatever reason, most here in the U.S. use "Standard Mode". I agree in that "Shootout Mode" should be requested, and it should be the Shootout Mode that measures wheel hp, not estimates 'bhp'.

BINGO!

I've seen variances from the Mustang Dyno owners as well and those don't have "shootout mode".

you should always get your graphs with at least

Wheel power, wheel torque calculated from that
AFR and manifold pressure.

Air temp if your interested in that as well.

If you want flywheel then it´s just a selection for the axis. It´s multiplication factor is based on DD´s removing engines and fitting them on engine dynos and seeing what the drivetrain was loosing. Then giving out factors for such drivetrains. This will ballpark it "well enough".

Meh no use in spending the energy justifying the dinosaur with it's schweet MS Dos based software. The Dynamics Dynos are also hard to strap so the tires tend to want to spin on those tiny twin rollers. If I want a load dyno I'll go to a Dynapack Dyno thanks.

[gstuning]

Meh?

The DD comes with Windows software and has come for the last few years.

I have not had a car spin tires on the dyno. It´s all in the strapping technique.
The DD machine is the most popular dyno in the UK by a long shot. And considered the standard here in the aftermarket.

You obviously have very limited experience with the dyno, so I feel your opinion of it´s usability is not valid.

You are correct. The one I have experience with the guy most likely has had it forever and never bothered changing the software/hardware setup. It probably has a few nice features if that many people like it and use it I imagine. I am not a dyno operator and was only going by my own experiences with it...and compared to a Dynojet or a Dynapack, they all suck.

Lol Cam.. A DD or Mustang are worlds better than a DJ or Dynapak. Expand your horizons bro! :buttrock

The Mustang is cool as long as the dyno operator knows what he is doing. I do like the Mustang as a load dyno a hell of a lot better than the Dynamics. There is no "Shootout Mode" for the Mustang so you just have to trust the operator.

Give up, he's not listening.
