I would not spike twenty all day everyday on my car but I think it's fine for once in awhile at the track. You should have plenty of fuel so I say go for it
*EDIT* South Florida serves 93 octane
Well I have the boost set to 17psi with the downpipe open. Honestly I don't think I will be spraying the car that often. Im just gonna have it if I need it and for the track (which i go to twice a year if that)
Any ideas on the jet sizes? Im looking for info on it. Im gonna have a wideband to tune the car with. Its not mine so im gonna have to give it back after im done getting the jets right. What kind of A/F ratio should I be aiming for?
Thanks
