Racing fuel?
 

I just installed my JB4 in my G70 3.3 sport. I am wondering what kind of racing fuels people have tried. I'm planning to try some Sonoco GT260 Plus at 104 octane and see what I can get out of her. Does anyone else have any experience with using actual racing fuels in their G70/Sting 3.3? All the discussions I've seen have been about 93 octane or an E85 blend. From what I understand I may actually lose performance but I figure I'll give it a shot. If anyone has experience or more knowledge I'm looking for your insight.

Not sure if you're still looking for this info, but I have run that exact same fuel now a couple times in my GT Stinger AWD and have had positive results at the track. Map 5 is simply ridiculous, but I'd be nervous to use it on regular pump gas.

Did you end up giving it shot?
