Pump gas is always considered the highest available at your local service station. In my cas, 91 octane. I made 461 on 91 octane.
The fuel from that dyno run was VP c16.
Drivetrain consists of a stock GSR tranny with a quaife and stock OEM axles
At the track I run 13x8 bogart rims with 24.5x8.5x13 M&H slicks
