lag huh. maybe it is because its in the trunk. mine is in passenger fender and the moment i hit 4psi the light turns green and i see iats drop immediately.

i would just add some fuel in that area of the tune since the lag apparently will always be there.

My fuel is limited though, so my goal is to resolve the lag issue. Its bad, like 2-4 sec. I'm done going through the gear at that point. Do you know if there is a way for me to turn up the pressure on the pump?

Sounds likes it working well and like camuman said I'd relocate the tank seems like it has quite a bit of traveling to do before injecting that could be the problem. One question I do have Junky are you checking your lambda readings at all? Because your using a different fuel along with the gas shouldn't the afr be a bit off? But lambda should always be the same?!? Correct?

I'm not sure about what your saying, my take is i'm seeing the afr drop, the expelled gas is what

You can use denatured alcohol but its more expensive than methanol and slightly less effective at heat removal. Methanol is 262 calories/gram heat of vaporization whereas ethanol is 204. It doesn't really matter though, since the water is 540 calories/gram. I've use denatured alcohol occasionally (from Home Depot) but its about $8/gallon. Denatured alcohol usually consists of a 90% ethanol/10% methanol mix. Isopropyl alcohol is too corrosive to use.

You can run straight water, but usually people mix water with an alcohol so the water can't freeze, the alcohol is no longer flammable, and you increase your fuel octane rating alittle.

At full boost my intake air charge temperature drops from 150F to 90F. Your EGTs should drop 150-200F also

So you notice any white smoke?

At WOT I've seen light colored smoke, could'nt say it was white though. It looks like just exhaust coming out to me, and the AFR is fairly rich at WOT.

I just checked my plugs, compression, oil, coolant, and meth injection - all's good so the smoke is probably just rich exhaust smoke.

Meth injection should be part of every F/I application, water injection at the very least

What size nozzle is everyone using and what is the power output /boost of your car? I have a rather unorthodox set up but am using the med nozzle at 10psi about 360whp. I've got mine set to come on at .5psi and full on at 6psi, both the lowest setting on the controller. Though with all the lag from the pump I am experiencing I dont see any injection begin until about 3-4 psi
