water/meth injectio
i have been doing lots of resurch
im sorting out my water/meth injection im going to run 4 jets into the lower manifold or lower part of the top manifold on my 90 fc turbo 2 my question
car is going to be running about 350bhp any idea as to what size jets i need also any one know of any fail safe systems. e.g. electronic boost releife valve system to cut boost?
im in the uk so will be running 98oct shell fuel running about 17psi as i got a t04b with 61trim compressor wheel with stock fc exhaust housing should be good for about 350-380
suporting mods for the air flow is
cold feed air filter
greddy large front mount
fd upper manifold and tb
3" down pipe - 2.5" twin exhaust
t04b hybrid turbo (fc exhaust housing)

Not an AI guru but unless it's a dedicated competition car, why four nozzles and why (from your post I'm assuming you intend to) tune to it? Why not add after tuning should a nozzle plug or in the event of a pump/system failure.
Our octane rating system is different, but I didn't see any fuel system mods on your list either for that PSI or power level.

Here's some folks that have dedicated lots of time and experience with real world cars and no guessing.

The car is going to be used as a drift car. Hence why I wanted the jets as close to the rotors as there going to get very hot.
Fuel is the best everyday available stuff in the UK.
My fuel most are updated wilbro tank pump to swirl tank. With high flow pump to injectors.
Stock primary with 1000cc seconds with fully loaded greddy emanage ultimate.
My psi is going tks be between 14-18 depends on turbo output.
Yes the car is going to be running a lowish 370bhp but with 4 jets I can use maybe 2 pumps so even if one fails it will still cool giving me enough time to back off. Why I want a safety system building into it.

If you want AI for cooling at the combustion chamber I think water will do the most and it does it during phase change...from liquid to vapor in the combustion chamber. Doesn't matter where in the intake system it's introduced.
If you want to cool the intake charge with AI, methanol works best but it still needs some time to absorb the heat. So introducing it really close to the combustion chamber (rotors) will reduce efficiency, not help it.
Not sure what you said after that. But regardless, if you tune with it I have some doubt you'll have "enough time" under WOT.
