Auxillary Injection ONLY ::: NO INTERCOOLER

[stylEmon]

I thought ya'll might like to see the results of my latest data log.
Specs are Garret T04E .60 compressor, 1.24 turbine
Tubular manifold, tail 38mm wastegate, 9 lbs spring.

Devil's Own 150 psi pump
50/50 distilled water/methanol
M2 nozzle pre-compressor
M7 nozzle post compressor


I especially like how the AIT keeps going down as the boost and RPM go up.

yep, I use water injection on every forced induction build I do, cheap insurance.

I am using only AI for intercooling. I may eventually run an intercooler as well, that way it will truly be insurance.

Do you use devil's own or aquamist?

by insurance I meant it really helps prevent detonation, allows more timing and boost on pump gas also. I've used most every brand out there, currently running Snow Performance.

i see what you mean by insurance. Most people I've run into use AI in addition to physical intercoolers.

I would run pure methanol for the cooling. But I run at least 25% water for detonation deterrent. Since it's cold, I've gone up to 50/50.

water is a much better heat absorber than methanol. The methanol does give a slight octane boost, and adds additional fueling since it burns (which may or may not be an advantage), but for pure heat absorption go straight water.

I had a procharged 540 without an intercooler and straight water injection, made over 800 rwhp with our crappy 91 octane. The stuff definitely works with or without an intercooler.
