It doesn't matter - any race fuel is fine. You're just autocrossing - 1st and 2nd gear. Get whatever's the most affordable (100-104oct).

how much boost can you run with alcohol injection?
i ask because i see ppl always make more power with c16. with c16 you can preatty much run as much boost as your motor can take with no knocking. c16 can preatty much max out any turbo. since c16 makes more power i assure alcohol injection has its limitations.?
can u max out a built motor with a gt35r with 91octane and alcohole injection (30+ psi of boost)

Most cars can be maxed out on alky as well...stock turboed evos put down nearly the same horse on both...just look at the track times for stock turboed cars...no difference...

C16 just has more power potential than meth or alky - quite a bit more. It's not all about how much boost you can run, but how much you can run and still run lean AFRs with aggressive timing. C16 is way better, but meth/alky do a great job for maximizing your daily driver.

UCC, good lord, man, what's up with the new sig? Are you and all those guys EvoM paying vendors now? I didn't see your member tag change yet...

Haha, well I will be a vendor as soon as CharlesJ changes the tag...the only thing I sell is the Meth kits as we are a bodyshop in NY...the other ones in my sig are becoming vendors or are vendors at the moment...
