Supercharger kit 
brings you dramatic increases in power while not degrading everyday drivability 
or highway gas mileage! The system utilizes a large blow off valve that remains 
open at cruise and light throttle. This, essentially, allows the supercharger to “freewheel” under 
normal conditions, reducing parasitic loss to less than that 
of an alternator.        
       
A naturally 
aspirated engine would require higher compression, a very aggressive camshaft, 
high flow cylinder heads with heavy duty valvetrain, exhaust headers with free 
flowing exhaust, larger throttle body, high flow intake manifold, free flowing 
air filter housing and duct, etc. Most of these parts are NOT emissions legal. 
The price of these components alone is higher than a supercharger system. The 
labor to install these is also much higher. Then there are the inherent problems 
brought to the vehicle by such a build. A large camshaft all but ruins everyday 
drivability AND gas mileage. Driving in traffic becomes a very trying 
experience. A stick shift car will buck and surge and an automatic car will be 
hard to hold back because of the increased idle speed required. Low speed torque 
is reduced with an aggressive camshaft which will require lower differential 
gearing and a high speed stall torque converter (automatic cars) to make up for 
it. This further degrades drivability and gas mileage. With all the components 
required for a high performance naturally aspirated car, the degradation in 
drivability and gas mileage, the total inability of the vehicle to pass 
emissions tests and the added expenditure, the vehicle would STILL have up to 100HP less 
than a stock Corvette with one of our standard 
systems bolted on.        
       
Average 
increase TO THE REAR WHEELS is approximately 
175 RWHP! No other modification, in this price range, 
even comes close.
