This turbo was a monster.

Sure looks like a centrifigal blower and not a turbo to me.

I dunno, look at the fins inside of it.

   It is very deceptive looking but it is a cetrifugal supercharger.

The fins inside are for the intake impeller that draws in the air.  Basically that's where the airfilter will sit.

If you look carefully at the pic, on the other side you'll see the pully.

Thanks for posting the pic!  That's pretty mean looking!

Yes, it was a supercharger. What is really interesting is that these huge blowers can suck up as much as 350 horsepower just to turn them at full power. Personally I do prefer turbos. Not as fast to build power, but then again they don't bend crankshafts from the strain on the belt turning on of these monsters.

I read a statistic somewhere that said a stock 426 hemi couldn't turn a blower that is on top of a top fuel dragster. I have to agree I prefer turbos also, the parasitic losses are so much less than a supercharger, and if they are setup right and the the driver know how to "drive" there is zero turbo lag and make huge amounts of power. A guy I know is getting ready to work on a design for an engine that has both a turbo and a blower, and is planning on making quad digit power.

That's wicked!!!  Though I must agree that turbos have been the way to go for forced induction, they have come out with centrifugal superchargers that are as efficient in producing high rev's as a turbo, yet doesn't produce as much heat.  The advantage here was it would incorporate more of your engine's rpm range, rather than the problem most people face with turbos and the lag they tend to have when you're first starting out.  I wish I had a link to this, but it was in a magazine I read a couple months ago.  Definitely interesting, nonetheless.

I read that at a college, and I think that there is a little room for debate for that statistic.  The hemi could turn the blower, but due to the stock high compression, the engine would not stay together.  I would say that this would be true for all stock high compression motors.  Just remember that a top fuel dragster has about 7:1 compression and a bunch of other factors to keep it alive for its run.

I would hate to see what happens if a bird get's sucked into the intake impeller.

Shredded Tweet anyone?

This stuff is old news if you guys read Fastest Street Car.....The blower guys have been making big HP for a while now.

Heck, here's one mounted to the front of a Mopar in a Charger........

That's one of the benefits of having a low compression engine. (Maybe the only one?    You can slap one of these bad boys on without mods to the engine internally if you don't boost it too much.

Bob from the Supercharger Store said I could bolt one of these on my engine and make about 400hp.  Right now my engine is still stock so that means 8.5:1 compression, 240hp.  It would entail changing from power to manual steering.  Total I think will run me about $4000.

I am not trying to change your mind, but for $4000, you could easily rebuild your motor to make 400hp without the supercharger.  I am talking aluminum heads and all.  Just my

Still 1900hp short
