gsc s1 for sure

 

I wouldn't even dick with cams until you max out the stock turbo and possibly upgrade. Everyone claims huge gains with cams but I haven't seen many timeslips to back up those results. Full weight stock turbo and stock cam cars are yanking 116-118 in the 1/4 mile and I don't see cammed 9's doing any better.

Before wasting a handful of cash on something that provides little if any gains on the stock snail I would look into an FP GREEN or RED.

 

No one running Kelfords?

 

I just received mine in the mail. They did awesome in the AMS cam shootout, that's what convinced me.

 

Yeah, that's why I'm leaning towards them. Just wondering why no one is recommending anything other than cosworths for the 9.

 

Whats a good spring/retainer to go with the cosi M2's. I know they are not needed but I plan on revvving high into the rpm range !

 

i got the kelford 272 and i loving every bit of it. i had the gsc s1 in there before and they worked good with my first tune. but the kelfords are good

 

Did you upgrade the springs and retainers?
