The principle is simple: Air and fuel plus ignition equals horsepower; therefore, more air and fuel equals more horsepower. It’s the equation that nitrous systems manufacturers use to help produce incredible power gains—in some cases up to 400 extra ponies—in everything from sport compacts to dedicated race vehicles. Still, many performance enthusiasts don’t fully understand
I recently installed a NOS Cheater nitrous system on my car and we took it to a chassis dyno to test the system. The jets were rated at 150 hp but when we tested it, it only delivered barely 100 hp. The guy who runs the dyno said my fuel pressure was okay but the
You’ve got questions. We’ve got the answers—the Summit Racing tech department tackles your automotive-related conundrums. This week, we’re providing some basic nitrous system guidelines. J.H. Huntsville, TX Q: My 1998 3.8L Camaro is pretty fast, but not fast enough! I’ve already added a high lift cam, pistons, and new injectors, plus I plan on getting some cylinder heads
In a separate Mailbag post, we responded to a question about choosing a nitrous oxide system. Although nitrous oxide is a rather simple concept, tuning your engine to take advantage of the extra power potential can be a little involved, especially when you get into the high-horsepower or multiple-jet nitrous kits. Fortunately, the gurus at NOS have
You’ve got questions. We’ve got the answers—the Summit Racing tech department tackles your automotive-related conundrums. This week, we’re talking about nitrous system setups. T.H. Washington, D.C. Q: I’m putting together my first engine for my 1984 Oldsmobile Cutlass. It’s Chevy 454 with an Edelbrock RPM cam, heads, and intake package. So, how much nitrous can
Got questions? We’ve got the answers—the Summit Racing tech department tackles your automotive-related conundrums. This week, we examine ideal camshaft lobe separation for nitrous applications. D.M. Pitman, NJ Q: Can you shed some light on camshafts made for nitrous engines? Why would they have a lobe separation of 112-114 degrees, versus 106-108 degrees for an otherwise
You’ve got questions, we’ve got answers. We work with the Summit Racing tech department to help you tackle your auto-related conundrums. In this week’s Mailbag, we’re rebuilding a big block Chevrolet engine to work with a nitrous oxide system Q: I have a 1973 El Camino with a factory 454 big block. I have updated it with a
If the rotating assembly is the heart and soul of your engine, the camshaft is the brains. It controls the movement of the entire valvetrain, telling the valve when to open and close and allowing your engine to breathe properly. Fortunately, you don’t have to be a brain surgeon to pick the right cam for
