[Corky325]

ok so my car is a 98 328i when i got the car the guy told me that it had m3 cams and a shark tune. now i am begining to think that the tune was a lie or he took it out. if you look at it it looks my my vvt is kicking in to soon since the car seems to like above 4 grand

mods are obd1 intake m3 cams and 5 speed swap, stock clutch and flywheel 3.91 lsd and a shark tune,, i think..... its up in the air, it had a 6500 rev limiter which i thought shark got rid of that. i have stock exhaust, underdrive pullies,


is this hp right? seam really low but i could be wrong. and imput of the afr and drop offs would be great.

Im not an expert, but if your rev limiter is 6300, it is the stock rev limiter. That would mean it isnt tuned, and a 2.8 that has a m50 mani looses some torque. It is supposed to be gained back after tune, so thats somthing to look up to. The problem is you need to get a tune for either cams or no cams. And considering he lied about the tune, he is probobly lieing about the cams. So i would figure out what the diff are between the m52 and s52 cams and pull off that valve cover to see what cams you have. Then get the apropriate tune.

I would say something definitely doesn't seem right considering the torque loss and the rev limit. It could be a number of items but it's possible the VaNoS is stuck in one position or the cam timing could be off.

Software typically yields rev limits north of 6800 rpm so it appears to be stock software.

Typically, on an M52 motor with stock cams the horsepower does taper off after 6000 rpm. Considering the horsepower keeps climbing all the way to the rev limit, I would say it is very possible the cams were indeed changed. There's only one way to find out.

Build Date: don't know
Mods: s52 swap, 3.23 LSD, 98 M3 manual tranny, Dinan exhaust, Dinan CAI, fan-delete, UUC lightweight flywheel (aluminum), Dinan stage 1 software
Dyno Type: Dyno Dynamics
Dyno Conditions: Cold day
Gear Dynoed: 4th
Peak HP: 226
Peak Torque: 229

I dynoed my car for the first time since I've owned it. The swap was done by the previous owner. I did the tranny work and a few other things which are not relevant to the dyno figures. The numbers seem right to me compared to similar swapped cars or 96-99 M3s with similar mods. According to the previous owner, the car had been flashed with Dinan software (I'm guessing stage 1, judging by the mods). I'm concerned that either the software isn't actually there or something might be wrong. What do you guys think of the dyno curves?

[Juicemg]

pretty good results but I think torque graph could be better

Better as in higher numbers, or flatter? Does it look to you like it's still running the stock software? I've been holding out on getting upgraded software (probably going to go with AA) until I can do the M50 mani swap, euro HFM, injectors, and cams.

[Juicemg]

flatter yes.
I think it could have an OEM software

nice results
what is the compression?

thanks. first time doing internal engine work so big learning experience.

pistons 8.8 but im guessing around 9 after cleaning head/block surfaces. head had some damage from leaking coolant. i might CC the head when i pull it for turbo manifold.

I had to stop at 200 since i got max injector duty cycle error. I need to install the M3 cams and Injectors i have sitting here looking at me.

My AFR was running .86 lambda to .92 lambda for the entire pull or 12.3~13.5 as you can see there.

anyways more fuel needed up top as you can clearly see from 4k to 7k I need to get it back around 12.3 and a little richer at redline to cool the engine off just a bit.

But I was happy with 200 off 2.5 cams

Oh yea, I have not hooked the vanos up to the motec yet. Notice I have smoothing at 0 for the chart. I am trying to tune it as close to a perfect curve as i can.

Im not an expert, but if your rev limiter is 6300, it is the stock rev limiter. That would mean it isnt tuned, and a 2.8 that has a m50 mani looses some torque.

I dont think you have s52 cams. Look at my chart with 93 325is cams with 175,000miles on the head.

Yea if i can pump some more fuel in running the same basic setup you have I would like to match your power minus supersprint headers plus stock higher compression pistons.

bmw 328I 1997

-M50 manifold
-S52 camshaft
-Fan delete
-M3 clutch fly PP and Rear diff
-AA c30-94 SC at only 5psi
-Heavyweight M5 copy wheels

Outpout power- 271 rwhp (corrected)
Peak torque - 234 lb_tq

soon on the same Dynojet with- oem 15" wheels
- 3" mandrel bend custom exhaust
- turner motorsport headers
- Now with 9psi boost

Can't wait to see if i'll hit the 300 mark, wish me luck

hey Mustangturbo50

By the way, i've dynoed my car last year with M50 manifold and S52 Cam with tune and it gave me 207hp and 184 lb/tq, from what i see, you probably got the M3 cam cause your torque is very low for a 2.8l , in stock form my 328i was 186lb/tq, my guess is you got the M3 cam and Mani but no tune, cause 99% sure that no one is selling a tune without putting rev limit to 7000rpm, and theyre is a huge difference with/without the tune, believe me, put a Jim or AA tune on this and the car will fly

P.S. your AFR seems pretty rich for a NA car, maybe it doesn't help out

I have 2.5 cams and at 2000 rpm im putting 140 tq on the ground. M3 cams would be a bit stronger down low. I am looking for my m3 dyno chart to compare it with. I cant read the one that is in m3 dynos

[Silli]

M52b28 Euro touring -96

Cams, intake, software (Siemens MS41.0)
There was best pull 252 hp with freeflow panel filter. Dynosheet is with stock filter with 98 octane fuel.
Its measured as crank power.

nice numbers man...but they are measured at the crank right?

[Silli]

Yes its corrected crank power. I Dont know power from wheels

Who did the software for you? im looking for cam specific software for euro 328i . thanks.

[dhinez]

I had an oppurtunity to get my car dynoed for free but didn't wake up early so I messed my chance. I was wondering what my fellow bimmer members would think I would make. My mods are in my sig. Thank you for a response.

[Chistakoff]

205-215hp!

[bimmer215]

Iwould say t least 200 if the engine is healty, good luck

Sorry but they do softwares only with dyno. But hey, welcome to finland. You might like it especially at summer

Updated new run with 199x 12v vr6 injectors (bosch 20lb 12ohm)



I cant wait to try it on the street. It is 2hp from what my m3 put down...just 20ft lbs tq differece on torque

Anyone have a full exhaust with a race header?

[bimmer215]

Finally an update with my car running good, i just did 13.2@110mph at napierville dragway, but my M3 clutch cannot hold on anymore, after 3 run it was slipping bad, nevermind, i'm happy with the mini-blower now
