Thanks. The tires were a few track days old and I just did a couple 'hot laps' to show the owner what the car can do, but at least there's now a decent video of Buttonwillow Config #13 CCW since none of them out there showed the line very well.
Hey Billy, just watched the video you did with Speed Phenom:
Thanks for the support! Those were always fun races at Daytona.
I grew up in Southern California and feel your pain. But having done a lot of the development driving on 93, and having tested the GT500 on 91 in CA (and driving Joe Gatt's 500 in CA) I honestly can't feel a difference. Even going from 91 to 100 at the track from one session to another, you're unlikely going to feel a 1-2% change in power at this power level, if it even does that. For street driving, I wouldn't bother with octane booster. If you're going to the strip or track (you'll be refueling a lot on track) then do it if you want to spend the $, but you don't 'need' to.
Great video, thanks for sharing everything with the community. I have always had the philosophy that running higher octane at the track in my tuned / blown S197 was cheap insurance. Do you feel that is not really necessary here in California with 91 Octane and tracking the car on a stock engine? Would you recommend an octane booster for track days as an alternative to fueling / mixing 100 octane which is what is commonly available at the track?
It's probably a good idea to run higher octane in your blown S197 or any car on track with an aftermarket tune. All of these aftermarket tunes don't have the same attention to detail, safeties, and time and effort as the OEM calibration that ensures your engine doesn't blow up on track.
Thanks buddy!
