The procharger sounded even more like an alien spaceship. Had a steady whine/whistle to it when it drove by. Yeah, it wasn't "tuned" and wasn't available for test drives either. They really didn't seem to have a lot of information. Here are a couple more offerings to the collection:

To set it up properly for a car with a 9000 RPM rev limit means no power gains until 6000 RPM and a significant loss below 3500 RPM to drive drag.

Looks nice, but not so sure it is the correct solution.

Ive talked to the company that installed this.I dont have number handy,but if you call procharger they have it.Now that i see pictures i understand why that small cost.I was told in the 4k range which seems in line with what im looking at.
That looks like an sc1 not a 2 like the 350 kit uses. Im looking into buying some type of head unit now and getting the plumbing made up.

I'm somewhat turbo-literate, but not very sc-literate. Sorry I apologize in advance for the stupid questions, but...what are all the hoses leading out of the picture? I count three, and it confuses me. The compressor has one going off to the passenger side, and one going out front, and then the throttle body has another one going to the front. Do the two pipes heading forward connect and form a U, with the air intake coming from the one on the passenger side? This seems like a pretty contorted air path.

I also agree with MazdaManiac. The exact problem you (MM) described is what Knight Sports is seeing with their centrifugal S/C kit. You'd be better off with a turbo. However, I feel that there is some serious potential with a positve displacement S/C like whipple or bell...something that will also suit the personality of the 8 very well...

Now that some of you have seen pictures of this car from Rotary Revolution, there seems to be renewed interest in performance numbers. I will try to stop by and see what I can fnd out from Larry in the next few days. We do have a chassis dyno in town and I will see if he has plans to take one of these cars for a few runs.
By the way, I have gotten to know Larry over the last year or so and both he and the Sunflower dealership are top notch from what I can tell.

Showoff, you have problems with Sunflower also. When I went to buy my car from them, they couldnt find my car in the system, so I sat around waiting with my thumb up my azz for over a month. Indep Mazda had I was looking for so I went there, and they had the nerve to be upset with me. I waited patiently for over a month and still no car.
I'm scared now to use their service department given our history and it's like 3 miles from work. Oh well.

Yes, those are Vortechs claims, but even down to 3000 you have as much or more torque than the stock.
Also don't forget the "turn-on" RPM is ratiometric with the redline. If that "turn-on" RPM is 3000 on a typical 6000 RPM Redline engine it will be 4500 on a 9000 RPM redline engine (i.e. 1/2 X 9000 = 4500 RPM not 9000 - 3000 = 6000 RPM).
I have to agree that any torque reduction down low is going to be a bitch on the RX-8 that has little down there to begin with. However, I don't think there will be much change one way or another down in the 3000 RPM range.

Yes, a 25% increase in torque in the mid-range, followed by a 50% increase in torque in the high-end would be quite welcome by me, if it came with no lag and a cool(er) engine compartment. Of course the Renesis is a completly different animal from a VTEC power plant, but the Honda curves are nice. This is going to boil down to the same quality vs. quantity arguments that I've seen waged for years on the Miata forum.

Would just like to see it on a dyno. It will be interesting to see what it does for the tourqe. My understanding is that supercharging a rotary really boosts the tourqe alot.

I think that depends on what kind of turbo you're talking about. There are a number of different varieties, all of which provide different benfits and have different trade-offs. I can't keep them straight though.
