Electric Supercharger

There's only one electric supercharger that actually does anything... the Thomas Knight Electric Supercharger. But it needs two extra batteries and an upgraded alternator to work. Since it's run off of batteries, it's sort of like Nitrous... after using it a dozen times, you'll have to recharge... unlike Nitrous, you don't have to pay to refill... you just wait for the alternator to top the batteries up. The base system costs about 70,000 pesos and is not available locally except by mail-order.

It's only good for small four cylinder and V6 engines. The custom wound high power electric motor (15hp worth) can't push enough air to give appreciable boost on V8s. Heard about this years ago on the Nissan boards, as they used a Nissan Altima as a test car.

Everything else, like the Turbonator, the Turbozet and the zillion other plastic computer fan "superchargers" is fake. No matter how many rpms they claim their fans can do, the simple fact of the matter is that they can't push enough air to give you any power. You might feel a tiny boost at just above idle, but once past that, the fan will just slow your engine down, as it becomes a restriction in the intake.

Not to mention the danger of your engine chugging broken plastic fan blades if the air pressure accidentally sucks one of those cheap plastic pieces into your valvetrain.

EDIT: PS: I almost bought a TurboZet myself, years ago... for the Sentra... until I thought about it and realized it was a waste of money. Some people claimed a slight bump in power, but others said it did nothing... in other words... baka "psychological effect" lang siya. So I just went ahead and got a muffler instead. Didn't do much more, but at least it sounded fast...

EDIT2: By the way... this is how big the Thomas Knight kit is:


This is a 15hp electric motor that gives about 6 psi of boost on a 2.0 or 2.5 liter engine. If the electric motors aren't this big... they're probably not strong enough to give you any appreciable boost...

If the motor looks like this:


it's producing maybe 0.5 psi of boost... at idle. At full throttle, they're probably producing negative boost, and will be restricting airflow to the engine.
