Using boost by smith NOS harness, comes in at 6500rpm in 1st, 50%, then 100% in 2-5th at wide open throttle.
I run C12 to be safe.
Motor AF is about 13.2, spray, 12.2, very rich and conservative. We pulled the motor Sunday just to check everything, all looks good. No signs of detonation or lean. Tear down was aimed at replace V springs.
