Custom Water/Methanol Injection System

Thats a trick setup to feed cool air to your procharger. A little off topic but is the electric fan mounted to the hood for additional coolingto pull the hot air out of the engine? Curious to know how well it has worked for you.

The fan itself pulled about 5 degree's out of the temp that the car ran at. It took me from about 195 to 190. It also greatly reduced under hood temps. When I cut the two custom openings in the hood for the cold air box and to let additional heat out, it dropped the normal running temp to about 180 degrees.

Beautiful setup, gorgeous car. I am also adding a meth injection system to the 1973 turbo 455 trans am I just bought. The car did 887 hp to the rear wheels on the dyno at 15 psi, so accounting for a 20% drivetrain loss with the automatic thats 1064 hp at the flywheel. Give or take its still a lot.

The system I just bought was from coolingmist. Its a trunk mount system, 250 psi pump. I too wanted a larger tank, but didnt like anything under the hood.....I have limited space there in the first place. So this unit comes with a 1.5 gallon tank and the pump is mounted on the tank.

David there talked me out of a complex controller. He said unless I was looking for the cool factor, just bring the entire system online at about 65% boost and be done with it. Considering the guy sells controlled systems, and he is the owner, and spent 15 minutes convincing me NOT to spend more money.....I conceded. LOL. I can always add it later.

Very curious what your #'s will be with the larger cc nozzles you are installing. David recommended a 760cc, and a 380cc totalling 1140cc/min for my combo. Sounded like a lot to me, but I too was thinking about maybe just starting with the 760 nozzle, then adding the other to see the difference. Interesting that its so much more than you started with.

Sounds to me like your setup is similar to mine in some ways, and I was expecting a 50-60 hp increase, as well as the added protection in addition to the intercooler to prevent detonation. From your example I think I'm at least inline with those estimates.

Question........what percentage meth were you running on the dyno, and what do you plan to run regularly? Were the #'s on your dyno runs actual rear wheel hp, or corrected for drivetrain?
