[QUOTE="dan1982, post: 16626820, member: 196375"] On a semi-related story.. i have a 600hp motorcycle(bought from a member here)... i run 18pounds of boost on 93 octane though(400hp) with an ams2000BC... ive owned it 3 years, and ALOT of work went into this build.. and ALOT of dyno time went into it...
