Its really picky about the air and temp...He asked and I thought I would ask here since.....a)it was a good question and I know his situation b)It was a rule question I couldnt answer and wasnt going to call NHRA tech for since its not my car and its not THAT important....

But it got me curious too.....

I told him just put some MCormic blue food dye in the water and if anyone asks its just windshield wiper fluid and youre too lazy to drain it Besides youre FWD and the weight up front cant hurt....lol

Now Im curious though....

Tell your boosted little buddy to try -20/-25 degree blue windshield washer fluid. Its basically a 50/50 blend of water and methonal. The h2o is for cooling and the methonal helps cooling but also aids to increase the octane rating to 115.
