Just an idea fuelled by a lovely bottle of Sellion Chardonay but is it possible/adviseable to wire an aircon compressor into the charge cooling system to cool the air charge down ?

Would the power drain be more than the potential gain?

It would need to have a massive volume.

Why not use methanol injection. I normally see 10 deg below ambiant or n20

it was just a thought based on the aircon unit never running out like a meths injection system or Nitrous would and therefore something that could be used continually.

wouldnt work, because the effort required to run the aircon unit would more than eliminate any potential power gains

first law of energy conservation!*

as sd says, water/methanol injection into the throttle body will do a much better job (mixed 50:50), although you will need a tank and pump to do this.
i know a guy in the usa who runs enginerunup.com who might help you out in this respect




*i think, its definitely one of the laws of physics tho!

i really ought to either drink less or think less when drinking

btw, isnt it semillon chardonnay?

spot on

I believe a sports car manufacture used a very similar approach but im am unsure what the result was.

Best thing is to go pre turbo water injection.

hmmm - now that is an interesting thought thanks scott.

I was happy with my Aquamist injecting post intercooler, its hot enough still to provide the energy for the phase change that reduces the temperature, and thats where Aquamist suggest its done.
I often thought about using Ethanol in with the water, but never got round to it. If you're going to rely on it you need to invest in the sensors that check that there's water in the tank, and that the nozzle is not blocked.
