ok this post was origionally to notify everyone of my dyno numbers with these new cams, maybe you should bring these questions to a new thread or post in the GSC cam release thread.

I know it has something to do what the ramp up rate and lobe profile just like AL said, But I do not have the actual numbers, those numbers you will have to get from GREG at GSC him self.

I am nothing but one of the if not the first one to buy and install these cams then take them to get dynoed before and after tuning to show potential. Since then have been some what of a rep for GSC but again I dont know the actual/exact numbers I did not design these cams, or done any extensive research. Hope you understand, and I hope my self to get these numbers. I've talked to greg a lot and he said he will put out the numbers eventually. Also as one post pointed out some info is on the site check it out, if you are still unsatisfied maybe you should call him if you are that concerned.

 

wow, nice gains I think that is the way I am going to go.

yes EVOTEXAS you and I. Your the first with 272/264 and I'm first with 264/272

 

Anyone interested in the 264/272 combo logicperformance should be getting them in around the 21st of this month. Or just shoot me an e-mail and I'll take care of you when they come in.


if you are interested in the 272/264 combo there are plenty in stock either logicperformance or contact EVOTEXAS and he'll take care of you.

 

but I'm asking for this...

 

Yes, I get it. I saw that the first time you showed it. But I never addressed you, so I'm not sure why you keep quoting me, like I responded to something you said. Like others have said, call the manufacturer if you need more than is on their site.

Sorry Evo11V for taking up your thread.

 

I think i might have to go with the 272/264 combo now

 

are the GSC's good with stock valve springs or do they need to be upgraded as well?

 

^^ I'm pretty sure you'd be fine with the stock valvetrain, people talked about that earlier in this thread.

 

sorry...i must've missed it...thanks

 

GSC !!!
i think am gono change my mind now and go for them insted of the HKS 264 i/e combo !
so when dos it spool up and wich part of the RMP do u feal the power in ?

i am looking for somthing wich can be used on track and autoX and some LS1 *** kicking !!

 

you notice the spool up less, you have more power down low but spool up about 3k I can hit full boost no problem, maybe a little earlier depending on the gear i'm in but 1st and 2nd definatly by 3k

 

still suprised how if they are the same specs, gsc are producing more power. something is gota be different

 

Nice numbers! Very similar to mine, but Im going to keep my HKS cams!
