bc 264 cams

[rwd]

anybody have before and after installation dyno sheet,..cause i 've changed my cams for these cams but at the same time i've change from gt4088r .95a/r to gt3788r .89 a/r and i lost power,i'm not sure if it's the cams or turbo

gt4088r/stock cams/23psi:575whp 550wtq
gt3788r/bc 264 /25psi:574whp 512wtq

and they made alot of noise

You lost power, but went from a bigger turbo stock cams to a slightly smaller turbo with 264s.. You lost alot of tq though.


Get them degree'd i'm sure you'll make up for some power.

but now i've changed all my setup for faster response...gt3582r .82 a/r , spa cast manifold , jdm stock cams , 484whp 464wtq.

what do you thinks it will hapen if i reinstall my bc264 cams,in term of response , peak power , torque curve???is torque and hp will be raise

I have a ported/polished head and BC264's on stock twins. Has a really healthy powerband from 2500-5000, but flattens out at 5k. Still pulls real nicely from 5-7k, but doesn't make any more power according to the butt dyno. Yes, you lost power, but I wouldn't be so quick to blame the cams. How's the response? How high are you revving it anyway? You're the one providing the numbers, do you have any graphs to give us ideas of your curves?

''gt3788r supposedly give the same power of gt4088r with the spool of gt3582r'' according to garrett.
but why this big difference;cams or turbo?? you can see the gt37 spool little bit faster than gt40,
can somebody proof that bc264 give more power on his setup , i knows couple of person with bc264 that have low torque curve too...
sure , i didnt degreed them but on the cam card supplied it write 0degre adjustment

gt4088r , stock jdm cams , 23psi not the final sheet....575whp

gt3788r , bc264 , 25psi

now i have gt3582r,what do you think it will happen if i put my bc264 , will i lose torque , response , for only raise about 20 peak 7000rpm hp?
