Not producing power and don't know why... HELP
OK I have a 2005 Honda S2000 with the following engine modifications
Brian Crower:
2.47 Stroker kit w/ 9:1 CP pistons
stage 2 forced induction cams
valves, valve springs, and retainers
Greddy Turbo Kit
Perrin manual boost controller
Inline pro fuel rail
RC 750cc injectors
Okada projects ignition coil packs
Invidia:
Test Pipe
cat back exhaust
AEM ems
Head, turbo manifold and intake manifold have been ported and polished. Head also has a 3 angle valve job.
ACT Clutch rated at over 360 torque also I have an ACT flywheel
For some reason after the first tune on a Dynopack I am only producing around 260 whp at 8 psi. And for some reason my torque curve just drops out after vtec engages. tuner suggests its due to forced induction cams but the desgin craft s2000 runs the exact same setup and produces well over 260 whp. WHY IS THIS HAPPENING????

are you getting a clutch slip loop on the dyno? I think the clutch wouldnt be able to handle that kind of power you should be putting out. Do you have a dyno sheet you can post up? It would help to see the power curve until VTEC and AFR readouts would be nice.

BC products were proven to lose power.
turbo cams will probably work on this setup, super restrictive exhaust system with a big motor..
post the dyno graph so maybe we can help.

it's the turbo. even though you have heavy internal mods, your biggest restriction is the turbo. If you compare your turbo size to the BC car, you'll see how dramatically different in size they are. With a ~2.5 liter, you should be at least running gt35r-sized turbo, unless you wanted a turbo that kicks in at 3k rpms and falls on its face up top.
