How much of cooling effect can I expect with alky?

[bruce]

Bruce thanks for the info--if I run straight alky then will I have to lean my tune a bit?The main reason I'm doing this is for cooling and to eliminate a very intermittant knock retard on hot days after sitting in traffick.otherwise the car is tuned pretty well.

I originally was going to go with a smaller pulley and use alky to make up the diff in fuel / knock protection.But I dont want to depend on the alky like that so since my car runs kinda fat now will the alky cause a drop in performance?

Basically my question is--How do I go about lowering my intake temps for more power?

In that case, you want to the *extra* fuel/ cooling effects of the alky, so no you won't want to lean it down. But, you said your *fat*.

It would depend on how *fat* your fueling is. If your say at 10.5:1 adding more fuel is just going to be uselessly fatter, you'll need to find the balance that makes your car run best.

You can lower the temps, mechanically, or chemically. Mechanically is using the most effecient Intercooler possible, and chemically in thur evaporation. And that's kind of tricky. You want to have large pressure drop at the nozzle(s), meaning small *jets*, so that you headstart the process, by using the smallest particles possible. Then you want to introduce them (afore mentioned particles) as early as possible to guarantee they have enough time to absorb as much hear as possible. Might even have to compromise and use several different locations/ nozzles.

Yeah Bruce--I too go for extended runs.The few and far between.Thanx again for your input.BTW my setup has the intercooler under the s/c so I cant go larger well,not cant but not yet. I am interseted to see if the effects of alky are compounded by the fact that it will be run through the supercharger and through the inter cooler cooling fins.I'm also moving the battery to the trunk to make room for a larger heat exchanger reservoir in theory to keep temps more consistant if not lower.I'm doin' a water spray for the heat exchanger too as well as the nitrous purge routed to the same.I'll be offline for awhile starting tomorrow so thanx again.--
