Depends on how much boost your running. The meth allows you to run more timing, which is where you see your power gains. If your running a 5-6 psi kit on a stock setup, don't waste your time an money.
From what I've been told and heard, no. Where these kits really shine is when your running over 10 psi.
Hit up Micheal Plummer over on the Corral. He has lots of real data he can show you and if it would benefit your car. Or just give Anderson a call and see what they have to say.
Ok I picked up a mr freeze kit pretty cheap off of corral figures it couldn't hurt. So where do I need to put the nozzle? By the impellers on the blower just punch a hole in the plastic?
