Cheers for doing that mrex180, although it must have been hell having to thrash your car around in the name of science :lol: .
Was that temp drop of 46-47'c with just the intercooler sprayer and not WI? If so, that's pretty impressive and WI on top would bring the temps below ambient.
(I'm guessing that's the WI
AND I/C sprayer though).
As expected, the temps didn't change much and it's very hard to test if the final temp was reached quicker or not. If I get the on/off spray ratio right then just using water will keep the temps constant and the inital quicker cooling of any alcohol would then be rendered pointless.
The upshot is, I have 25 Ltrs of methanol now :smile: , just waiting for a WI system to spray it with - bugger :cry: .
Thanks for your help and time on this.
