is this not the same thing as a centrifugal supercharger, what is the difference

 

Pretty funny to see this considering JR has continued to say for years that the S2000 volume did not justify a kit. I think they finally realized that there may be fewer S2000s than Integras and Civics, but the owners actually have disposable income and don't live with mommy and daddy anymore

 

Apparently its "the best of both worlds". You get low end power and instant throttle response (like a roots) from the "rollers" inside the compressor. And you get high end power, all the way to redline, just like a centrifugal.

I still don't know exactly how it works, but I know it is supposed to be lubricated be some sort of "special" oil and doesn't produce that much heat. I haven't seen a "aftercooler" or intercooler anywhere on the manufacturer's site.

I think the "rollers" inside the compressor act as a mini-roots blower and keep spinning at the same speed at lower RPMs to produce the lower end torque, but I really have no clue.

I'm looking forward to it, but I'm not holding my breath. I'm sure it will find some way to fall through the cracks.

 

just seems exactly like a centrifugal SC because of the way it runs off a belt to a pulley which spins the impeller and sucks air. dont see how it would create low end torque since there is no way to have it spool up like a turbo since it is being ran off of the engine. correct me if i am wrong

 

The Rotrex uses a planetary gear to step up the impeller speeds. They can get a higher impeller speed with a lower input shaft speed when compared to a traditional gear or ball driven centrifugal.

I'd rock one

Check out Wheel to Wheel, who does work for GM. They have done some very High powered LS1-LS7's with Rotrex units.

The sleeper Nova they built is a $$ taker

 

Perhaps since they started using the new SC they found they could get the performance and drivability they wanted at a cost they could market as a true bolt-on kit. Or the used S2000 market has put enough cars into the hands of the their target audience.

I never went with a centrifugal because it was lacking on the bottom end (ok my personal opinion) and turbo just seems like to much work and $$$. I have had JRSC's on a GSR and an ITR and loved them - great power and no problems from a company with excellent customer service.

Bet this kit will install easier than a Comptech and go like hell.

 

I called and the guy said on Monday there will be more info Since Oscar is at Sema.

 

It's not personal opinion...I'm a Comptech guy and I admit there's no bottom end power. However, I doubt you're going to find an easier install for an FI setup. Sorry.
