With over a year under our belt and no significant changes to the S1 Evo 8 camshaft set, we decided to change the intake slightly to allow for more top end power.. We found we could increase the lift to help out the upper rpm power band with out sacrificing the low end and Mid range grunt the S1 is known for..

These will be finished up next week, so get your orders in!

Awesome Greg!

 

These wont do me much good as I am way beyond a standard or mild build but I must say I love how you guys at GSC are constantly updating product and striving to make the community better. Seems like just when you got the best cams for instance, you find a way to improve, big to you guys!

 

thanks guys we appreciate it.. we try to keep on our toe's around here!

we are going to revise the S2 a little next month as well.

 

Sweet! As I plan on going w/ S2's next season I was just thinking this and you posted it.

 

Pricing will stay the same ??

 

i am glad to see gsc making the gsc s1 intake cam a bit stronger / more agreessive than the exh cam

 

Also would like to know this...?

 

given todays costs on the billets I will say pricing will stay the same on all of the Evo camshafts threw out the summer. I can't garrantee it will stay but so far it looks good.

 

Thats good to know, great cams getting better.

 

gsc are good cams always good reviews, and greg always has made time for me when i call him and ask him the same quiestion over and over and over and over.
the same quiestion (whats the best cam 4 my evo)?

 

I'm happy with my S1's in my evo 8. I've had them over a year.

So if we wanted to upgrade, we would only have to upgrade the intake cam?

 

in theory but the problem is we buy the billets in a pair, so if i sold 50 intakes to those that want to upgrade then we would have 50 exhausts laying around.

Given our cams sell pretty well used i would say its better to buy the entire set and just sell the older ones as used. it would probably work out to be a scrach in cost, where as the other way you would be stuck with the older intake as a keep sake.

 

Ya know, I have HKS 280's and never really cared for GSC's (for no real reason other than loving the HKS's), but it is freaking cool to see a vender updating their product as technology/testing becomes available to improve an existing product.

 

you know i get that quesion alot and each time it takes a little thought on my part. as redundent as it may sound everyone has a little different car and each have different driving styles and power demands. it deffinatly helps us make changes to cam profiles and keep up with what our customers need and want..
