What happens to the carburetor when you Supercharge an engine?
As a result of supercharging, a small displacement supercharged engine can produce similar horsepower and torque to a naturally aspirated larger displacement engine. With a Roots blower, the carburetor functions basically the same as it would on an unblown engine, except it now sits on top of the supercharger.
How are electric superchargers used in Formula One?
Although Formula One has come along and used electric motors for turbocharging purposes, electric superchargers have also been floating around the internet as a possible modification in the last few years. So how do they work? There are two types of electric supercharger. The first is more of a fan than specifically a supercharger.
Which is the second type of electric supercharger?
The second type of electric supercharger uses a donor turbocharger with an electric motor attached, otherwise known as an E-supercharger.
How long does it take an electric supercharger to spool up?
While turbochargers can take a couple of seconds to spool up and mechanical superchargers still having some inherent lag, an electric supercharger can spool fully in as little as 0.5 seconds through the direct connection with the throttle, giving virtually instant maximum boost.
How many horsepower does a centrifugal supercharger need to turn?
Drive losses for a centrifugal supercharger also vary depending on the load. At idle they only require a few horsepower to turn, but losses increase with speed. A typical after-market street supercharger can take anywhere from 30 to 50 hp to drive at full load.
Why do you need to tune a supercharged engine?
Without question, a supercharger or turbocharger system radically alters the parameters of the engine’s airflow and manifold pressure, so the controller’s programming must be altered to directly feed the engine more fuel. In a nutshell, that’s the goal of tuning.
Which is not affected by the supercharger at part throttle?
MBT is not affected by the supercharger at part throttle. MBT remains the ignition target at part load. There will just have to be a blending into the new higher load regions of the map. Probably the most widely used compressor in the performance aftermarket is the centrifugal pump.
