Nitrous Install - Cheap Street Chevelle

How To Install Nitrous-Oxide Injection On A V8-Powered Street Machine

Plenty O' Fuel
Being that high-rpm engine operation and an auxiliary nitrous system can easily overtax a stock fuel system, you should consider updating your car with a high-performance fuel pump. In addition, a fuel-pressure regulator is a good idea so fuel psi can be monitored. Often times, an aftermarket, high-volume, mechanical fuel pump will work great for nitrous systems in the 50- to 150hp range. But if you intend on running a heavy-duty nitrous system (such as an NOS Cheater Series or a Fogger setup), it's much advised for you to upgrade to an auxiliary electric fuel pump, such as one from Mallory. A few weeks earlier, we had upgraded project Cheap Street Chevelle with a new Carter 7-psi/110-gph mechanical pump, so our fuel delivery system was adequate for our new NOS Super Power Shot nitrous system.
