kinda....definitly a must for higher C.R. when running pump gas cuz....
meth cools the intake charge drastically...cooler denser air, means your able to run more timing, and higher boost along with its affect of "higher octane" meaning more hp, and reduced detonation.
meth straight can be used as a power adder and cool intake charge at same time
meth/water mix will mostly only cool the intake charge and add a few points to the octane (not much)
