good info on injection nozzle location

they actually recommend a combination pre-compressor and pre-throttle for best efficiency!

7. Staggered Injection
Staggered injection involves combining pre-compressor injection with an additional secondary nozzle positioned further down the turbocharger or centrifugal supercharger, such as pre-throttle body/carburetor injection. By combining pre-compressor injection with pre-throttle body injection, were able to improve the efficiency of the compressor while dramatically reducing air charge temperatures at the compressor and again at the intake for a combined synergistic effect. Furthermore, the secondary nozzle provides the necessary cylinder cooling, detonation control, and reduced EGT's which the pre-turbocharger nozzles does not.
Best of all, installation remains essentially the same and costs are only marginally more as the addition of a secondary nozzle and tee fitting are all that is required. We highly recommend the staggered injection for all turbocharged applications and high boost centrifugal applications.

I would rather have the lower efficiency over a fire hazard. Everything has its trade-off. This is not an appealing one. Especially since the methanol would be atomized.

well just water,, or not over 25% alky, i tried it and no way it can light ,at least by a torch. i suppose a spray and try it again.
Ah heck just put it on and go for it, this whole thing is about experimentation anyway.
you should see an intake manifold and connections after a Nitrous back fire!

I am injecting pure water through a 780cc nozzle in the greddy elbow and greddy type-r BOV is above 8" prior to the elbow and when i back off under boost i have water mist coming out the BOV and the hood has condensation on it.
And really doubt that you engine bay temps in the region of the bov unless your BOV is on the side of the turbo and blowing on the exhaust is enough to flash the meth, especially if it is practically a vapour after coming out of the BOV and you doing 100mph with ait passing thru the engine bay

I'm assuming people are using winter washer fluid... I plan to.
I snagged a copy of an MSDS..
Ultraclear windshield washer fluid -40*C
1-877-402-9581 (toll free)
Ingredients
Methanol 49-50%
Water 50-51%
Dye <1.0%
Surfactant <1.0%
Regulations Info
Health - 1
Flamibility - 3
Reactivity - 0
PPE Index - P
Physical Data
State - liquid
Spec gravity - 0.937 @25*C
Boiling point 79.5*C
Freezing point -40*C
Vapor press/vapor density (DNA)
Appearance - Liquid colored blue
Odor - low odor
Odor threshold (DNA)
Solubility - complete
Evaporation rate - 2.1 (BuAe=1)
Volume % volatile - 100
Fire/explosion
Flash point - 29.8*C (TAG)
Auto Ignite - 380*C
Lower flammability limit - 5.5%
Upper flammability limit - 36.5%
Dunno if that helps anyone, but I defiantly change my opinion on the topic. Keep the BOV away from the turbo.
