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)."

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

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.

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.
sounds like its not an evo buddy,
