Steve. Sorry for taking so long to reply to your question.

I can't give you a fair answer to your question due to the fact that my setup is so different from the typical TR setup used by most.

The obvious things that slow my turbo spool up regardless of the fuel are:
Small stroke and displacement. 3.06" and 224 cid.
Long and large ID primary tubular exhaust headers.
High lift, long duration and high overlap camshaft.
Low stall torque converter.

The things that slow my turbo spool up with the use of alcohol are:
A low static CR with methanol. 9.2 compared to a more typical 10 thru 12 to one for a blown alcohol application.

You're right that methanol burns cooler and has a lower egt than gasoline. But the products of combustion (exhaust mass) are higher. That more than makes up for the lower egt. I'm currently running a mixture strength that gives me an egt of 1200 F at the end of the run.
