it will help lower intake and exhaust temps but still pulling that much weight the motor is going to get hot if you hit any kind of grade or hill. Depending on year your asking to make 4x the wheel horsepower they make from the factory.

 

94 12valve, do you think if I put one of those in cab fuel adjusters for a p pump on it so I could turn the fuel down when I'm towing that it would help?

 

yes just limit the power for when your towing. As long as you know that's what your going to have to do you will be fine.

 

Water meth is worth it. I hit 652hp 1191 with a silver bullet 66mm turbo, stock head with studs, 22 deg timing, 191 dvs, 215 benched pump, ddp4s, stock injector lines, 3 big noozles of water meth 50/50 mix.
