centrifugal... not for me.

Why?

I'd rather go with an SC that gives more of a boost in the lower rpms. A centrifugal would give some gains down low, but not a whole lot. It would rock up top though.

I guess it would really matter on the size of the compressor though huh? With such a high rev range, it would be hard to get a turbo / centrifugal that could work on so many levels.

Interesting. Someone made an SC kit right under our noses. Gonna look up more on this kit.

sneakyyyyyyyy

Kind of cheap too..

At least its an alternative. It would have been nice if they had posted an dyno of some sort, or even said how much power you can expect.

engine management?

My mustang has a procharger and while it doesnt put alot of low end (which isnt necessary with a torquey motor) it gains PSI linearly with RPM's. Which means instead of the boost drop off you would see with a turbo youd see a boost increase. But putting out max boost near redline might not be good with this car. It is proabably an easy install since youll only need to mount the bracket to the SC and IC. I wonder if its a blow thru or draw thru setup? It looks like they are using a FMU with some sort of inline fuel pump to boost fuel pressure under boost. Will this work with the computer?

ATI makes good **** - but that's not "FOR" an RX8. See 'Universal'? I bet that is just a bunch of parts a body would have to 'fix' to get to fit.

That's a nice picture of a *turbo* next to that *supercharger* kit description, too...

Sunflower Mazda was building a Centrifugal SC RX8 (think it was even an ATI unit) for a while, but never got past the ECU issues, and the project kind've died on the vine.

That's what I was going to say, it was ATI that was working with Sunflower.

Thats no turbo unless a hot side turbine is hiding back there. Look at my picture in my sig that isn't a turbo either...

MadDog

Yep. My mistake. I'm too used to looking at turbos and twin screw SC's...

What fuel management system are they using?

Most likey they stole DNA Motorsports plans, and will use the same Microtech

this isnt an rx-8 kit- its just advertising a universal kit and the one in kevins post above is rotormasters kit

Sup C?

Wouldn't it be possible to fit the universal kit with some fabrication and an EMS like the interceptor and make it work? If not, why wouldn't it work?

rotarygod

That's too general of an assumption. If you sized the turbo properly, there is no boost drop off. It's not hard for a turbo to completely walk all over any centrifugal supercharged system.

On a large engine that has good low end and a narrower powerband, a centrifugal might be an option. The smaller the engine and the higher it revs, the less useful it becomes over the average powerband where it counts.

Centrifugals are not linear with rpm. They don't work that way. Boost rises with the square of the rpm. If you have 8 psi at 8000 rpm, you do not have 4 psi at 4000 rpm. You have less.

I see, thanks.
