Types of superchargers

kannibul · 12-23-2009, 08:30 AM

I've viewed centrifugal supercharges as a middle-ground between positive-displacement superchargers and turbo chargers...

Both in terms of how they apply boost and where...

In a sense...and I'm being very general with this, I see it as a worst of both worlds...but still better than no boost!

So I hear what you guys are saying, but how do you both feel when comparing the centifugal to a good single turbo set up mostly in terms of reliability??? but if you have any other input that'd be cool too..

A lot of the common downsides of a centrifugal can be overcome with good engineering and testing.

Basically, centrifugal superchargers are well known for having less bottom end power than a roots blower. However, this can be overcome by trimming the wheels and making enough changes to make sure that you have good boost on the bottom end.

It takes a lot of time and development but it can and will be done.

Can't freakin wait Kyle. I hope you have some more news for all of us soon!!! Hope all of you at Stillen have a Merry Christmas and many updates for us in the very near future!

so you're telling me that stillen is going to produce a centrifugal supercharger kit that works nothing like any centrifugal kit ever made so far for any car? are we going to see some exotic transmision setup with multiple gears so that the impellor is going to provide full boost below 4000 rpm? Not to be harsh but the boost maps explain themselves. A centrifugal is teriffic for top end power and street rides that it won't matter if they don't have squat bellow 3000 because that makes them more easily driveable. but from a dig the lysholm is king

edit: when was the last ime you saw a sub 5 second centrifugally blown drag car huh? never because all the time is made from the squat.

Too bad you can't get anti-lag launch with a S/C setup lol

Here's a good side of having of a SC setup, you can still keep your sexy long tube headers and your car will sound meaner and louder than a TT setup at the same boost pressure

I want an SC for Christmas!

Doesn't look like its going to happen, only 24 hours left..

Lol, get a bigger wastegate.

I was referring to the exhaust note not the air whooshing out

ok as much as i love superchargers a wastegate is the exhaust side valve guys you run it open and you will have bad azz turbine noise that is loud as hell. that said external wastegates and secondary o2 sensors don't agree so good luck there buddy.
