what is the best unleaded race fuel to run in street cars that have to pass emissions

[Bill Anderson]

Hi,

need some feedback on what high octane unleaded fuel you guys are running with say 15-20lbs of boost, need to be able to pass an emissions test...

looking at:

VP100 (aka StreetBlaze 100) and vp motorsport 109

thanks

ive heard sunoco 100 unleaded is pretty good too. as far as emissions i didnt think there were any states out there that still did sniffer tests. most are obd II now.

Um.
Why cant you fill up with 93 and drive it gently until your test is over?

Cali still does sniffer tests.

I dont think it will matter. An emissions test is only 2500rpm 25mph roller. Youre not going to be at boost during any of it. If your car is running right and you have the stock midpipe you should be fine to pass with 91 or 93.
