Street Supercharging To Build Maximum Horsepower
There is no doubt that supercharging is one of the best ways to build reliable good horsepower from a street engine. Done the right way you can add 300 horsepower to the engine in your muscle car; while having the dependability to drive it everyday.
Having almost done away with parasitic loss; the efficiency has gone up about 30%; allowing the supercharger to generate more power. We all love horsepower in our hot rods, we love to go faster any way that we can.
If you match up the engine build to the supercharger, and take in to consideration what your trying to do with the car; you may end up with the perfect car for you. A supercharger is one of the greatest things on earth for a muscle car.
You need to match up the camshaft, and heads along with a few other things, such as the right compression ratio of pistons in the about 9:1 range, and forged rather then cast. Make sure that the bottom end of the engine is strong; use a four bolt main block.
Street supercharging can provide you with years of great driving enjoyment. You should always use a forged steel crankshaft when building a supercharged engine. Make sure that you buy carburetors that are specially built for a supercharger engine.
When supercharging a V8 engine; you don't need to push major boost to develop the power. About 7.5 - 9 pounds will work for the street with most street superchargers. This should develop all the power that you need, while still being able to use pump gas.
If your going to use a fuel injection rather then carburetors, you will need to match the fuel injectors to your camshaft and heads. It's imperative that they spray just the right amount of fuel; or you could lose some of the power that your trying so hard to build.
Also when street supercharging timing is of the utmost importance to building power. The camshaft that you buy should come with a cam card; this car will tell you what the optimum timing is for that camshaft, if you do everything just right your car will be a beast of the street.
Rather you use a carburetor, or fuel injection you should make 100% sure that your air to fuel ratios are set correctly. The aim of setting these is to get the fuel mixture as lean as possible, without burning your pistons; this is the optimum setting for making mass power from your engine.
Make sure that your supercharger drive speed is over driven, or under driven right for your application. Obviously if your trying to generate power, you should over drive the supercharger. I usually recommend 8 – 10% for street engines.
This means that the supercharger would spin 8 – 10% faster then the crankshaft speed of the engine. You should talk to the person who's building your engine to figure out what you want though. Always consult with a high performance engine builder when you install a street supercharger.
This is just a few tips; it's not meant to make a you an authority on superchargers. If they are installed wrong; the damage to your engine will be massive, do yourself a favor, and read up on it a bit before your attempt to install a street supercharger.
Their is noting hard about it, all you have to do is pay attention, and make sure that it's done right. Make sure that you spend a lot of time when you install the distributor; an intake back fire can ruin your engine if the pop off valve malfunctions.
Take all of these things in to consideration when you build your engine, and everything should go fine. This is far from everything; but it's enough to get the job done. Take your time to build it right, and your street supercharger should do everything your want it to.
