What happened to all the kelford hype?

 

i was curious about the s2s also... im staying on the stock turbo but going to be getting tuned on 91 and e85. currently my mods are pretty basic... licp and full tbe. i am getting 1000cc injectors, 255 fp, and a few things ported when i go e85. anyways, my question is will the s2 kinda suck on 91 as in no low end power?

 

I went with the s1's to keep the stock valvetrain and because I got a smokin deal on them! I would say if you can afford the valvetrain work the s2's are the best cam on the market. Just my 0.02

 

Kinda answered your own question. They work, but there are better solutions to be found.
