If the cam is at 107 that should be good, timing around 32-34, under hard accelleration I see 11.0 A/F.

My timing is there. AF ratio is 11.5 @ wide open. thru most of the rpm range from 4000-5800 during water testing.

What intercooler? Is that info buried in this thread somewhere?

I've been looking at FrozenBoost and plan on getting a new one, soon.

Is your transom black when you're done, under 12.0 we loose speed. Are you still trying to run on pump 93 ? what timing on top ?

Prochargers intercooler fo the M5 I think its a 604?

I am still running on pump gas. @ cruise I can not get over 12.3 without it popping thru the intake.
Timing is 28deg @ WOT. After 3 hours of running at all speeds I have a light film of soot on the transom. I just cant lean it any more @ cruise. I even tried the NTK O2 sensor to be sure its accruate. after the last issue I am afraid to lean it under WOT much more without race fuel.

Did this boat ever go fast?

Updates?

He was thrown from the boat while testing and is no longer with us. RIP
