You can make plenty of power on stock GSR cams... I made 563whp on a stock sleeved LS Vtec with a GSR head and stock GSR cams... 24.5psi on an sc61

with gsr's, 540whp 27 psi b16 conservative tune. reving to 10k.
i say conservative because it was the first time we tuned a car with power hahaa. (well back in 06)

Re: gsr cams whats their power range
what does changing from gsr cams to itr cams do to your power band? will it make your set up want to rev higher?

I believe its not just the power upgrade but it probable has something to do with the lobes/duration as well. But hey I'm just assuming

Re: gsr cams whats their power range
My set up made peak power at 7300 on 9 psi with b16 cams. Would itr cams change where I make peak power at or would it stay the same? I know all motors are different but that is amazing to see on your dynograph. I would like to keep my peak power lower something like the way mine is now.

Re: gsr cams whats their power range
^^^ definately get something else besides those b16 cams. they must be a real bottleneck on your setup. i think you will find more power from the midrange and up, not sure how much higher you will make peak power though.

Re: gsr cams whats their power range
I was looking at the marks on them and looked them up and they are the B17 cams. I don't know what the difference is but thats what they are. I would like to get something better but I don't want to turn the motor harder than what I am now.

Re: gsr cams whats their power range
If you dont want to Rev any higher than dont, you can clearly see all the power is not made at redline.

Re: gsr cams whats their power range
I was thinking that they must be closer to B16 cams than GSR cams. Would changing to GSR's help spool my turbo faster? What was the setup on the dyno you posted ?

Re: gsr cams whats their power range
Red graph was on stock GSR cams/Blue was ITR cams
Both were on 14psi and both on the same dyno
AFi ramhorn
880cc injectors
E85
57 trim
blox IM
Tsudo 70mm exhaust
Tuned on crome pro
pretty simple setup and you can see the gains are pretty damn good in some areas... i would pick up some ITR's if you can..if not atleast get some GSR's i have some for sale if you need em
