I have a novi 2000 with custom air to air intercooler on my car. I push 11lbs and I am pretty happy with my power levels. I live in Arizona though and I want a cooler intake charge when I am racing someone or going all out through the gears. I'm not really looking for more power I just want to cool the intake charge. Would I benefit more from a meth/water injection system into the throttle body? Or would I be better off with a c02 setup with a intercooler halo?
