TURBOCHARGER OR SUPERCHARGER?

TURBOCHARGER OR SUPERCHARGER?

Dear Sarge,

Recently I received, in my e-mail box, a UTV Action news story about a Turbocharger with an electric motor. While that is interesting, isn’t the unit acting as a “Supercharger” until the exhaust flow increases beyond the capacity of the electric motor? Inquiring minds want to know!

Private Worthless,

You obviously have an intimate knowledge of internal combustion engines. Essentially, until exhaust pressure exceeds the capacity of the electric motor inside the Turbocharger, it is acting as Supercharger. For the E1 Boots, a supercharger pushes air (boost) into the intake and is powered by a belt from the crankshaft. The main difference with this electric motor powered turbocharger is regardless of the exhaust pressure or crank speed, there is constant boost pressure at the intake giving the operator instant throttle response. This innovative setup eliminates the main problems with both the supercharger and turbochargers, throttle lag at low rpm’s. The supercharger has low boost at low rpm’s because the crankshaft pulley driving the supercharger isn’t s spinning fast enough. But the supercharger will respond quicker to throttle up than a turbocharger, which has to wait for the fuel to be burned and exhausted to power the turbocharger. Boot if your MM score from the ASVAB is at least 95, then I strongly recommend you consider a MOS change to 1341, 1345 or 2146. Dismissed!
