So refresh my old memory on what the ratio should be to safely run at peak hp?
Stoich is 14.7 and I am seeing max of 10.8 at WOT using the methanol......11.5 under heavy throttle.
What do you others run?

A bit richer is normal for WOT operation, particularly with modern adulterated gas. Running lean with methanol can wreck an engine in short order.

I was running 11.1 at WOT, before my last tune. Now it's 12.0 or so.

Thanks, I was hoping you would chime in....

I must be a little richer due to the addition of methanol in my 50/50 cooling water mix.
Under heavy throttle the A/F is 11.5 - 12.0 but as soon as the juice starts to spray at 8000 hz it drops.

Are those phenolic intercooler plates still available?
