I would run a primer plus system with a hat on a tunnelram . Max power, quick warmup on gas and the ability to clear out the alky at the end of each pass so it saves on fuel costs and preserves the cylinder bores during storage and races. I have a single terminater now, and not having the primer plus eats up a lot of alky plus like i said earlier causes problems with bore corosion if you don't do a perfect job of clearing the motor of alky.
A well setup car is absolutely deadly consistant, right up till about 96 percent humidity. Then there is a serious dip in power because of the high humidity. I think it amounts to about .04 in the 1/4 on my car, been many years since i had to deal with that.
On timing, methanol runs best with about 2 degrees less timing than gas.
Throttle response with alky injection is killer. Idle is very fat on an injection system, and fuel is waiting at the intake valve! The first pass i ever ran with an injecter it went right on the bumper launching off idle. What a surprise that was.
