I've got anther question as well. After the Warranty on my Camaro wears of... I DEFINITLY plan an making it the baddest car on the street, and I plan to use a supercharger as the main ingredient. However, I would like to not have anything sticking out of my hood  ...sooo - what do you think of the centrifugal supercharger? I hear they are the most efficent, cheapest and smallest...... |
yeah when I say blower I mean supercharger. heres the deal with centrifugal supercharger. its basically a turbo with a belt driven pulley on the back and uses a longer belt. but it only spins as fast as the engine spins, so inside it has step up gearing that puts at around 60,000 rpm. with that being said the power gains are in the higher rpm's. so it works best on cars that have to be in the higher RPM's and have good low end power to compensate. you'll have to run a oil line from your oil pan or crank case to the supercharger. Im not the biggest fan of centrifugal superchargers because they're too much like turbochargers. and they're belts have been known to shred. but if you go this route vortec is the only way to go.
roots style blower the air isnt actually compressed. its gathered and forced into the engine making positive pressure (boost) as the air backs up into the intake manifold. Because the blower doesn't use any step up gearing and doesn't need to spin very quickly, the internal rotors always turn at the same RPM as the engine. so the blower will always force the same amount of air relative to the engine, even low in the rev range. Making the powerband feel like it came from a larger displacement engine. the only downside is its size, and heat. heat is taken care of by air to water intercooler system built into the blower and it all replaces the upper intake plenum and rests right on top of the engine. a cowl inuction hood would work just fine...but depending on the clearance the stock hood may work too. its all on what you like best
