whats the difference HP wise..the cr would be low(9.1....for turbo) and i'd be spraying a big shot of n20 before i go turbo....anyhow n/a how much gain would i see swapping gsr cams for itr cams?

 

if its for turbo, get the gsr cams, gsr cams works pretty well wit turbo applications.

 

or run low boost on itr's....

why?

so does anyone know power difference n/a between these 2? i know they both work great with turbo

 

because granada sun said so, and thats the bottom line...

no gsrs are set up cause they have secondary intake that opens up at like 4k, which is right about where turbo is boosted.

itrs are for higher rpm power.

gsrs have a lil more midrange, but itrs have much more power overall on the top end, which is why i say low boost, unless the engine can handle power at high rpm's.

 

umm ok still dont make sense..all you just said is that itr's make more peak power, lol so still unsure why i should just run low boost... this is on a fully built motor

 

details that could have been brought to attention at the beginning of the thread...but anyways, on a turbo'd motor with stock internals, high boost + high rpms + high rpm power = high repair costs.

where its built it should be ok.

Well ITR cams will **** on GSR's in the midrange and top end. As will CTR cams. What the hell does choosing GSR vs ITR cams and low boost have anything to do with handling power at high rpms or anything for that matter?

There has been a lot of luck with GSR cams. As well as ITR's. ITR's are about the peak duration one would go with on a street boosted car. I haven't seen back to back numbers on same cars, but I have seen plenty of GSR cammed boosted as well as ITR cammed and even GSR/ITR and ITR/GSR all with good results.

I'd love to see the results on teh Crower Stage 2T high lift rel. low duration cams.

N/A...how about this question without the concern of boost? the gains of itr cams replacing gsr cams?????

No one said anything about GSRs making more HP than ITRs....what i meant was, that if you are going to run a lot of boost, and not upgrade internals, then gsrs would be better choice...not upgrading internals is stupid with boosting anyways, but safer than ITRs would be.

 

Well first off you said GSR cams will make a little more midrange over ITR. So technically you were the one to say this. However you misinformed because CTR & ITR cams will make a VERY NICE midrange gain over GSR cams.

So let me get this straight. If I have a bone stock GSR motor and I boost it, then your theory is my motor will be safer with GSR cams then ITR cams? Technically speaking there is a slight possibility because of the greater overlap of ITR cams, but in real world no way. I'm sorry it's not going to matter. Personally I think GSR cams are great for boost. Not worth the money investing in the ITR cams unless you can find a killer deal and test them back to back however, they are not going to be unsafe if you do use them.

 

You're probably right, you've got more posts than me.

 

But isn't the big difference between running these cams for Turbo the duration vs. lift and overlap? With R cams, there is much more overlap which is not that good for boosting, that is why a lot of people choose GSR cams instead I believe. If I'm completely wrong, then on me.

 

You are not completley wrong. The point I was trying to make is stock ITR cams is about the most overlap you would want in a cam for a street boosted car. They are not dangerous as there isn't a "ton" more overlap then the GSR cams. As I've said I know people that make great power on GSR, ITR as well as ITR/GSR and GSR/ITR. Now if you are talking about running something like a Skunk2 stage 3 cam which has one of the highest durations on the market that's another story.

 

You should make more hp with ITR cams on boost. Just ask TEAMGENDAI. 647whp on a dyno that reads low.

it doesnt have too much overlap...seems just perfect.....motormatrix...559whp@22psi.....itr cams, set 0, 0
