GREAT numbers!

How many miles on the engine btw?
78K miles but the engine was rebuilt 7K miles ago.

those are s54 torque numbers, good job
Thank you Sir.I did some pulls with E46 M3s all done up,NA and i put on some of them 3 to 4 cars and only one of them i put 1 car.
E39 M5 with headers,cold air intake and software,i put 1 car and a half on him from 0-100mph.

nice numbers. what rpm's did you make peak hp and peak torque at?

kinda OT but it must be nice to have 78 degree weather compared to 97 degree weather down here.
I think im gonna have to take it back to the Dyno when it gets cooler OS.My car starts to Climb up hard at 3000RPM,no power loss at all till 7000RPM.im gonna try to post the graph.

those r some good #'s. could u post dyno chart?
Thanx!!!!
I will try and post it today.

Those are great numbers no doubt, but I suspect the dyno is overly optimistic. SAE corrected, those numbers are achievable with Sunbelt camshafts but are outside the 99th percentile for Schrick cammed cars. That or your car is a factory freak.

I'm not sure why people believe this. My car dyno'ed with similar numbers 5 years ago and nay-sayers said the same thing. It then dyno'ed a few weeks ago on a different dyno with similar results.

I know of at least 5 other schricked cars on this forum that have dyno'ed 260+ whp (dyno sheets were provided/posted). I'm sure there are prolly many more who have not posted their similar numbers.

Depending on what was done with the engine rebuild, his numbers are more than very credible.

Go to the strip and post your average trap speed over a few passes... that will tell you if that dyno is reading high or not. I think 270 whp on an off-the-shelf tune, regardless of mods, is optimistic at best.

I'm not questioning who as much as wtq. I saw your numbers, and I can understand 260+whp with Schricks, but he's making almost 20 wtq more then you! Something doesn't add up here. :confused

That's what I was thinking. Sunbelts are definitely capable of those numbers, but for Schricks those are crazy high. I wonder what the OP had done to his head during the rebuild? :conf

The torque is quite high, and made relatively early for
such a high output S52. My car previously dyno'ed at 256 trq on a different dyno with different mods. I have seen other schrick motors dyno in the 245+ region. It's not unheard of.

I think a lot of you guys look at dyno numbers for car-to-car comparo/dyno-war purposes, which is futile when dealing with different dyno's and different conditions, etc. A 10 whp swing from dyno to dyno is the norm.
Getting bent out of shape because a car dyno's 5-10 whp or trq higher than one thinks it "should" is pointless.

Makes a lot more sense now. A worked head is fully capable of those kind of numbers. Did you go with bigger valves as well???

Great numbers. Sunbelts would probably yield at least 10whp/10wtq more, considering how much more aggressive they are.:evil2

Which Sunbelts? Their street/sport cams are worth about 5 whp and a loss of 10trq. vs. street Schricks. Not worth the cost and install effort, IMHO.

He's already had them, they're FS in classifieds. I've seen a consistent amount of dynos showing Sunbelts gain atleast 10whp/tq over Schrick cams on s52s. You and only a few others have put down really high numbers with Schricks. The peak torque is definitely higher with Sunbelts, but it does come on later than the Schricks.

Beavis

07-26-2009, 01:37 PM

Standard size Ferrea valves, over size valves are unnessessary.
Sunbelts would only show gains over 5200 rpm and would have big losses from 3-5 thou
Evo sport cams show better top end than Sunbelts but with the same losses below 5500 rpm and they require a Idel set above 1000 rpm.

You have seen before/after dyno's of schrick street cams vs. sunbelt street cams on the same car and same dyno? Can you post or direct me to them, please?
Can you post or direct me to 270+ rwhp sunbelt street cam dyno's?

Not being confrontational or "challenging" you, its just that I've never seen any data to support that Sunbelt street cams are "superior" to Schrick street cams. The cams are VERY similar in spec - the Sunbelts have slightly more duration but less lift. This tiny difference in cam spec just does not equate with substantial gains. The head to head test I linked to confirms this.

BTW, ask Beavis what kinda numbers his car put down w/ schricks . . .

There is sales and internet hype . . . and then there is reality. Lots of folks have been in the 260's w/ schrick street cams. They don't post about it because its old news. Back in '02, one of the beta-testers of the original Conforti cam kit dyno'ed in the 270's with full exhaust and mild head work.

Evo sport cams show better top end than Sunbelts but with the same losses below 5500 rpm and they require a Idel set above 1000 rpm.

My neighbor is running the Evo's on his CR car and reports he has no idle issues.

If you look at the area under the curve from 4k to redline, the Schricks win hands down . . . again. The Schricks enjoy a 20-25 hp/trq. advantage in the midrange.

Sorry for doubting, and you have plenty of reason to prove me wrong. I've only gone off of the Dyno Sheet sticky, b/c it's my only real access to dyno sheet evidence. You never answered my question regarding your mods for the 256 wtq you got on your last setup. Care to inform me??? :D

I'm still baffled to see those numbers on off the shelf Conforti software. My TMS tune for 3.5" hfm, 24# injectors, intake, headers and flywheel performs horribly compared to my custom tune from RMS. With full 2.5" exhaust and and OBD1 manifold on my s52, I put down 225 whp/222wtq with the TMS tune and had a horrible AFR curve. With the RMS tune I put down 237whp/232wtq, with perfect AFRs! :buttrock

All Conforti cam kit dyno's have super flat and correct AFR's, regardless of other bolt-on mods. Conforti is hands-down THE best BMW tuner in the world. Period.

I'm not trying to "prove you wrong", its just that often misinformation gets repeated often enough on the internet to become a "forum fact", even when empirical data says its bunk.

My old set-up included a URI crank pulley, HIOP headers and the Schricks were set-up for max mid-range trq., and it was dyno'ed on a superflow dyno (reads 5-10 higher than a dynojet). The motor also had 100k miles on the bottom-end vs. 150k now.

e30 polak,

You realize the TMS cam kit is different from the Eurosport cam kit, right? Different manifold, different software . . . and the TMS kit is about 20whp down on the Eurosport kit.

One of the cars you listed is an S50, and the other is not a Eurosport cam kit motor.

What "conforti tune" are you talking about with regard to your car, "the shark injector"?

The Eurosport Cam Kit is a comprehensive kit that includes Conforti OBD2 software that is optimized for the schrick cams, 24lb injectors, PORSCHE HFM, M50 manifold, 3.5" CAI and 93 octane gas. This cam kit software is totally different from what comes in "the shark injector". It is this cam kit software that seems to always be flat as a board in terms of afr.

The "M3 dyno thread" is relatively new and very limited. Folks started running the Eursport cam kit back in '02. There have been more than a few dyno's of the kit posted over the years.

Plus I think a lot of people would argue that Stickley is the best tuner. ;)

Stickley's (and everybody else's) tuning is based on Conforti's work. Stickley is an engine builder, primarily, and does not tune OBD2. So, considering BMW stopped using OBD1 over a decade ago, I'm not sure how or why anybody would argue that he is the best BMW software tuner in the world. :dunno

I have the OBD1 tune for the 413/506 DME tuned for: 24# injectors, 3.5" HFM, headers, CAI, LTW flywheel, speed sensor delete, and EWS delete. This is on my OBD1 s52, so there could be a slight difference since it's tuned for an s50.

I thought the TMS kit came with the OBD1 manifold for s52 cars, my mistake. Didn't realize the difference between their kit and Eurosport. No wonder why their dyno results are so much weaker on the OBD2 s52 kit vs. the s50 kit.

Either way, I will be getting some cams reground to Schrick specs in the next couple of weeks and will post dyno graphs after Osh tune's the car. If all works out I will also have a nicely built head with over sized valves from my friend. :devillook

Well there was no other choice really. I'm OBD1, I finished the swap 3 years ago, I hadn't heard of TRM yet, so I went with TMS. After talking to the tech over the phone at Turner, he said there wouldn't be a problem, and that many swapped cars/OBD1 s52s ran their chips with no complaint.:confused

The motors are very similar other than a mere .2L of displacement, I figured that it would work just fine. Mods are the same, whether s50 or s52, so there isn't a world of difference. Most other swapped e30s have gone the same route, whether it be s50/s52. Oh well, I've lived and learned. :shifty

Plus, I prefer paying someone for dyno time and tuning, rather then just downloading a program on to an EPROM for the same price. :rolleyes

I never said E30Polak was arguing. Please read above.
I don't think its fair or reasonable to fault the less than optimal results of an "off the shelf" tune designed for a different motor vs. a custom dyno tune. Apples vs. tennis balls . . .

What do you think would yield better results? A custom dyno tune by Conforti or Osh's "off the shelf" S50 chip plugged into an S52 motor? It's a useless comparison.

Regardless, he had the wrong chip for his motor.

He should contact TMS and im sure he can work out a deal with them to fix the problem.

My TMS Chip has "OBD1 S52/Euro HFM/24# injectors" printed on a label on it...

Mine just has the number that matches the application guide. When I bought my chip 3years ago, the salesman/tech didn't have an option for an OBD1 s52. He said that he sold my chip for the same applications with no issues. :shifty

Either way I love the way Osh tuned my car, and with my upcoming build, I'd rather have dedicated dyno time. I'm hoping to put down close to the same number as the OP and MadDog, with a fully worked head, Schrick regrinds, and a port matched Schrick intake manifold. :devillook
