Need help choosing cam combo!!!

[REDspydergst]

So after racing a friend that is putting down 400whp I decided that it was time for me to drop in some cams. I stayed about 2 feet of his rear bumper all 3 times we raced.

I drive 2g gsx 18g turbo running 20 psi, greddy fmic, safc2, 3'' exaust, running e85 on stock 7 bolt. My question is what set of cams is the best option for my setup? 264/264? 272/272? 280/280? 264/272? I leaning towards the 272/272 combo but not sure yet. The cams im trying to get are DELTA. I heard nothing but good things about them even though they are regrinds. Please let me know. Thanks.

just go with a set up kelford 272's they are beyond proven and will help you with up top power when your turbo will be losing efficiency.

Go with the GSC S2 set. They are 274s. They are less aggressive then the Kelfords and more aggressive then the Delta 272s. Perfect cam for your 18G.

I have the Delta 272s. They die off around 7700rpm

I'd go with 272/272's, My friends car has BC 272's and it is still very streetable, has a nice lope and the car definitely has to be 400whp, breaks all 4 loose from a 40 roll in second on 32lbs.
