Not on the turbine side, on the compressor side From the reading I've done, your cooling at the source of the heat so it's most effective, and also helps seal the turbo so it's a little more efficient

 

Yeap that's the benefit from meth injection when spraying at the wheel. Start cooling right at the source where all the heat is created .

I just recommend having a quality turbo in a nut shell you are spraying liquid on a hot metal part so the goal of the game is to start before the wheel is red hot. and also use a small enought nozzle and enought meth in the mix so you don't damage anything.

 

If you do it before the compressor make sure you spray some well atomized dropplets. You start throwing some liquid meth at blades spinning 70,000+ RPM your gonna be looking for a new turbo.

 

If you are using it simply for cooling, then you cannot beat 100% water. It has a higher latent heat of vaporization than methanol, and it's CHEAP

Works fantastic on my NON-INTERCOOLED setup. Without the water, at the top of a 2nd gear pull, my IATs are around 210F. With ONLY water spraying, and no intercooler, my IATs are ~130 after the same pull.

You can see in this pic where I am injecting the water. It's just before the first orange silicone boot, right in the compressor outlet.

 

I'm in full agreementship with the above inoculation. My reliance is heavily reliant on a double-sized reliable air-to-air inter cooler. When the cooling medium it requires relinquishes, the running of my engine will retire. I sure miss the octane boost that methanol provides, though.

Mines not a truley fair comparison, but when I added meth my IAT's stayed ambient at 9lbs of boost. instead of like a 25* change

 

Would or would it not, if sprayed before the turbo inlet be considered a "quasi" oxidizer as well as a fuel. As its cooling effect pre-turbo would have the added benefit of creating a denser charge to compress, therefore netting a greater volume of O2 content post turbo? Just a thought....

Agree though, it's greatest benefit is cooling the charge post compressor!

 

While I agree that it IS one more system to break down or need maintenance it is a necessary evil when pushing the limits of compression with street fuel, expecially in states with lessor quality in the name of emmision control

 

20 million Turbo Buick guys can't be wrong.....

LOL

 

i have done tons of testing. IMO an 50/50 mix is the best mix where you can get the benifits of both worlds.
