ProCharger
Has anyone put on the pro charger kit? or know any details on it. From the site i found it on they put it on a stock ride w/o tunning it and got a ruff 303 whp and around 200 tq any buddy got more info on this system

without tuning for fuel/spark control you cant make power like that, you'll destroy the motor as the stock PCM maps cant handle boost(or much of it) on its own
probably thats with their base tune, meaning YOU dont have to go and have it tuned... there is some stuff on the site here if you look about this kit i think

I say embrace the high RPM power band of the rotary and stop trying to change it by using a twin-screw type supercharger. The procharger will deliver power all the way to 9K+ RPM's and do it with cool air and do it very smoothly. If I wanted low end torque I would have bout a GTO, but I want a 9K RPM red line.

To each their own I guess.

For a track car, I think a centrifugal would be a logical option. And of all the types of SCs, this would by far be the easiest to package...factory manifold, throttle body location, etc...

I've already researched the Mazdatrix Procharger. Honestly, yes they are built for cars that have enough problems getting their wheels to catch traction naturally aspirated (a Corvette is a great example). The C-2 Procharger is pretty over-priced compared to other kits, and while the horsepower numbers may be competitive, the torque figures are (and never will be) anywhere near other kits. If you're addicted to 150 revolutions a second, the Petit Supercharger and Esmeril Turbocharger seem great. However keep in mind that the GReddy (by far the cheapest way to go force fed) will go to 9K rpm, its just at around 7500 rpm the boost levels will drop down to their factory settings regardless of what you've done with a boost controller or waste gate. Frankly I wouldn't supecharge the RX8. Turbochargers have been proven to outperform any supercharger on the market at any rpm in torque (which is the whole reason you buy a supercharger is for low end torque) for this car. Also a turbo won't hurt your gas mileage quite as bad.

If you have not driven a procharged RX8 then how can you say it does not accelerate strongly? Have you read what people have driven it have to say? Again, I am not saying it is the fastest car but it has its place. It is a great track car and it has a stock feeling, meaning it is very smooth and predectible.
Here is a review of an 6PSI kit:

And a second, also 6PSI

I dont care what you do to the RX8 it is not going to accelerate like a corvette, gto or even a mustang. But just because it does not make tons of low end torque, does not mean it can not be fast.
I can spin the tires in first gear N/A and it goes through first gear in what 2 seconds? By the time you shift gears the car is in its power range mean while the turbo is still spoiling up. Sure a turbo can make full boost at 3K RPM's but just because it can, does not mean it does it in every situation. Correct me if I am wrong but a turbo wont reach full boost in 1st gear and usually not in second gear either, right? Well a procharger will.
For me, I want a track car. Sure a turbo can make more power but will it always make more power? How about on hot days when you have to turn down the boost or not go full throttle?
I could be wrong but I am just going by my personal experiance seeing what happend to other turbo charged cars while at a track and reading what other RX8 owners have experianced.

Don't take my word for it, go pull up an online 1/4 calculator that takes into account trans/diff gearing, vehicle weight, aerodynamics (.31) and see what having 250 torque gives you over 200 torque. The difference is not trivial.

Okay, so I am wrong about how fast your turbo is spooling up and getting to full boast. I was speaking from the experiance I have had with turbocharged vehicles.
Dont get me wrong, I think that the turbo rx8's are very fast and can probably make more power in most situations, but everyone is judging the DNA procharger kit on 1 mazdatrix Non-tunned, week motor, 6psi dyno pull. The kit can proform much better. Look at the DNA motorsports dyno charts. Now I dont know how to read torque on there charts, but a stock RX8 gets about 140-150 HP and a procharged 10PSI kit is breaking 300HP, that is a 100% increase. When HP and TQ numbers are being quoted for turbo kits, everyone is using the best results from a properly tunned vehicle. It would only be fair to do the same for the DNA procharger kit, the problem is that we dont have enough data look at.

Centrifugals suck on small engines. Period. That's physics. Have fun changing those laws. Keep them on BIG engines with low redlines. That's the only place they are useful. For our engines, damn near anything is a better match.

I will agree with your statement that they suck on small engines if you mean they do not drasticly change low end power. A centrifical supercharger does however make great high RPM power and moderate low end power. But any thing that can make a 100% increase in HP at High RPM's and a 50% or more increase in torque from 4K RPM's and up does not suck. It just does not do what you want it to do. Oh and it does it at a fraction of the boost of the turbo cars.

The C-2 isn't a horrible kit, but compared to everything else out there it really is behind the power curve. I was interested in the C-2 once upon a time and everyone was all too eager to show me the error of my ways lol.
The stage 2 (the only version worth getting) is $8,000!! You could probably get the GReddy turbo kit AND the MM upgrade for that kind of cash!
Prochargers are great for cars with huge engines, more torque than they know what to do with, and have enough trouble getting out of first gear without leaving half their tires behind. That sound like an RX8 to you?

If it were me, and I wanted a ~300whp car the GT30 would be a good option. But if I were looking for a lot more to build into the RX-8 over time -- and the capabilities for high hp 400+whp RX-8s will inevitably get here -- than I'd go with the C2.
I used to be really down on centrifugal units on rotary engines...and I still don't think they are in most cases the best options, but more and more I do think they have their uses even for us...
