Pettit Racing’s Forced Induction System
Last edited by Moon Assad; Sep 26, 2007 at 12:48 AM.
Be sure and post it cuz a few of the local gas stations are able to skirt the EPA regulation and sell 100+ octane gas as "Racing Fuel". I seem to remember some earlier postings saying it was not a good idea but i've not been able to find the posts (most likely cuz I'm using the wrong serach critiera).

I'm a little confused with this post and others...if no one is experiencing knock/detonation on their SCs, than why raise the octane? Unless you change the ignition timing, adding 100+ octane shouldn't add any power, and perhaps may cause you to lose power.

Apology not accepted. Now I have to hold a grudge against you until the end of time, or the end of this forum, whichever comes first!
I'll be very interested to hear your feedback since you are always concerned with operating temps, and since you drive at the track...
I also had asked Pettit on the forum a while back regarding usage of a larger reservoir - or if there even was a reservoir - for the IC setup, but never got a response. Basically expressing my concerns regarding operating temps for us track junkies. Sadly, I think that's about the time that I and a few others were told to "shut up, please".

Well I will say this...
After running The Tail of the Dragon at Deals Gap, with 318 curves in 11 miles, my Intercooler was nice and cool like I have stated several times. Most of the Dragon is run in 2nd and 3rd gear at high RPMs for longer than normal lengths. The clutch is ONLY used to shift gears as you would drive in track events.
I honestly think it is safe to say that even on track day... you would have 0 issues with the charge temps.
