E36 M3 Dyno Sheet Library

[speedinfusion]

clearly states on the graphs "flywheel torque" and "flywheel horsepower"

these were off a dynapack(chasis dyno) not dynojet..here, from teh church automotive website...

"Let's work through a comparative example for the same car on a Dynapack and Dynojet.

Car A produces 205 hp to the hubs on the Dynapack. This would equate to between 225-230 hp at the flywheel. The same car produces 195 hp to the rollers on a Dynojet. This would equate to 222-226 hp at the flywheel. Furthermore, the difference in power matches up very well with our calculated difference due to inertial losses. And interestingly enough, we have tested just such a car on our Dynapack and a Dynojet back to back with the same results (actually 196 vs. 206 hp)."

221whp on a stock S50? That's the strongest stock motor I've ever seen. You don't think that is a bit high with no modifications? I feel like I'm missing something here haha.

no no, there is a conversion on sean churches website

Update on my previous reply in this thread ( http://forums.bimmerforums.com/forum...79#post8680479 )

since replacing my head gasket and replacing all of my exhaust valves (they were all slightly bent due to a mis-shift a while ago) i got re-dyno'd at the same place and picked up 10rwtq and 5rwhp.

mods are same as before:
M50 Intake Manifold
Conforti 3.5" CAI
AA Custom Software
3.5" HFM (unplugged, refer to previous reply here for explanation)
Fan Delete
Strömung Exhaust
UUC Stg2 Ltw Flywheel w/ Stg1 Clutch
AA Track Pipe





again, yes it is a dynapack and no it's not flywheel hp like it says. it does read a bit higher than a dynojet because hp is measured at the wheel hub, without the drivetrain loss of the tire/wheel.

for the sake of comparison a stock e46 M3 dyno'd at the same place and pulled 246rwtq/296rwhp. from what i've seen i believe it reads around 15-20 higher than a dynojet, there's an equation to figure it all out on their website like speedinfusion listed: http://home.earthlink.net/~spchurch/...ting/id12.html

22 nos?

[UltimateM]

Yes, 22 NOS and 14 FUEL, in each fogger, thats with 45 psi fuel pressure, and an avg. of 1050 bottle pressure. It is definitely running rich I could probably clean it up by drilling my own .135 (the bit is available in the NOS drill set) fuel jet but I will be increasing the NOS instead.

On a mustang dyno?

[328 is man]

yea on a mustang dyno down at currys in VA with an ecis cai i came out with 173hp and 190 tq

Congrats...that is some beastly torque.

But srsly....all dynos are different

[PointMEby]

Just took my car to the dyno. Here are some numbers i'm content with.

My mods are...
Intake
Exhaust
Fan delete
Flywheel
I've got 110,000 on the odometer and it has factory software

[NakNak]

Strong numbers for those mods

Thanks, I thought that as well. I was expecting 215-220max. I always knew this M3 pulled abnormally hard though.

is that like a 100 shot?

Car: 1997 E36 M3 evo - 321BHP - UK car spec. (STOCK)
Just had Dyno Dynamics standard shootout mode results - real bad..

check these out and let me know if you also think these numbers are dreadful.

wheel torque: 210 ft/ib
wheel HP: 195.9 HP
Crankshaft HP: 239.8 HP

BMW say they cant run any diags on the engine to see why this is? cop out i say. they spend all my hard earned money on part changing if i let them.

thanks for any replies.

[kjprince]

sounds like its not an evo buddy,

[Tochenzo]

WHp is even lower than the avg US M3

[zparker]

I dyno\d my M3 before i went to race SCCA. I had been driving the car for at least 2 hours and it was 95 deg F with 35% Humidity. I am using this as my baseline performance for comparison after i finish the turbo project on it.
