So i have itr camshafts in my gsr. does this setup mess with the compression.
Also my car is not as fast as it should be, it is about as fast as a stock gsr. so any ideas

mod list:
DC headers(dented)
skunk2 cat back exaust
skunk2 intake manifold
aem sri
stage 2 clutch
light flywheel
aem fuel rail w/adjustable fpr
ported polished head
billet engine mounts

 

Cam's do not change copression, the only things that affect compression are things actually in the cylinder, or affect the size of the cylinder. Eg.- Head gasket size, machined surface of head, valve dish, piston height, combustion chamber.

 

i bet you're not even tuned

 

Believe me, even a 10-20 hp difference is not THAT noticable.

Honestly, this is what I tell everyone, if you are interested in your car being FAST, a noticable mod would be a b16 tranny. You dont need to make performance upgrades to accelerate faster.

 

Funny your mod list doesn't include a p28 with any sort of tuning software...I can bet that's the problem

 

tune

 

You gotta tune to get the most out of what you have.

 

If your car is not tuned, the engine will fall on its face at 4400 until about 4800 with ITR cams. The compression should not be affected provided that the cams are installed properly.

 

also a good fuel pump would help. But we have no idea what year you have and is it the stock motor. for ecm reference.
