I think he's trying to lower the actual under hood temps so the electronics and other parts will last longer. Water,meth,alcohol injection is just to cool down the air intake and allow the engine to boost higher without detonation. More boost = more heat. So I don't think thats what hes looking for....or is he?

 

Synthetic everything(tranny, diff, engine) will lower temps. Less friction=less heat. You may also want to wrap your headers with thermal wrap as well.

 

OK guys, thanks for the input.

I have done almost everything to keep the underhood and engine temps as low as possible.
Header wraps-yes
Synthetic fluids- Amsoil tranny fluid and engine oil
One electric fan is constant, the other turns on when the AC is on,
Both fans are the highest CFM I could find
Larger radiater/more efficient (Fluidyne)
Vented Hood (HKS Kansai)
Larger opening for IC and thus more airlfow to radiator
TRD thermostat
Tranny cooler (Earl's temp-a-cure)
Also even running a Power steering fluid cooler (Earl's temp-a-cure)

The only other thing to get may be a heat sheild for the twin snails. Maybe an oil cooler

Right now I am trying 15% radiator fluid/ 85%water and Purple Ice (Royal purple's version of water wetter) I am still trying to get some Engine Ice, but this will have to do for now.

This may be overkill, but I just don't wanna risk overheating and the problems that come with it.

 

i think you covered all your basis. i know in hawaii, it can get really hot so perhaps your only option is to move to a cooler climate

 

i'm gonna do all of this (minus the hood) as well to prepare for FI if i wanna go that route later lol good stuff !!!
