Wagz is an unknown quantity at this point

if i run race fuel (higher octane) i can take my set up to roughly 25psi safely whereas w/ 93 octane about 18-19 is the safest w/o detonation

O, now that I think about it. On that dyno chart of your car was that on race gas or pump?

keep in mind i havent dyno'd my current set up - that is a low end estimate until spring when i dyno and fully dyno tune the system - but that # will be on race gas at about 24-25psi
