rx789gtus

i was wondering if anyone has any ideas about supercharging a non-turbo GTUS...i think it would be cool, so if anyone has any ideas or websites that talk about doing this or show possibility let me know. Also wondering if it is even possible to set-up.

Atkins is the only "known" shop that makes/sells supercharger kits for the 13b N/A. The thing that keeps the FC owners away from that option is you have to convert to a carb. I would never do that myself. Also they are "roots" style superchargers. If you find someone elses thats making them the "good" way let us know.

i've seen people with Vortech Centrifugal type blowers. In fact one of the winner of "car of the month" on www.fc3s.org had one. He put down about 235 RWHP, with the stock computer. But the TQ response is INSTANT.

Is this a kit that can be bought somewhere? It would sell like crazy if it was. Well if it was reasonably priced.

Atkins is working on a fuel injected setup for the supercharger. What I think turns some people away is that there is no easy way to use an innercooler with the S/C.

REALLY! Sweet, how long till they are gonna be selling that bad boy? Their business is going to be moving on up.

Any engine can be supercharged and the rotary is no different. But there is really no point in supercharging an engine that is already available in a fully developed turbo version. If you want forced induction, save yourself a lot of time and money by buying a 13BT.

Sure there is! The point is to have an engine that looks and sounds cool. Granted, a supercharged NA 13B would be inferior to the 13BT across the board, but some people don't care that much about actual performance. In that same respect I would also make a case for the carburetor, because if you are going to strap outdated parts onto your engine, why not also go with the carb? It makes perfect sense to me. It's like an old school, retro kind of thing, that is intended to impress the technically challenged people of the world (ie the majority) rather than to produce optimum performance numbers. It sounds like a great show car setup to me.

For those who like the Atkins supercharger but want fuel injection, they supposedly offer a fuel injection conversion as a special order item.

If Atkins isn't selling the FI kit yet for some reason, those who like to do things themselves can always get their own Holley universal throttle body and slap it on the supercharger.

Sure, I think that a good J-Spec 13BT/fuel system upgrade/EMS is a much more practical and efficient project, but I'm one of those boring bean-counting people who never has any fun.

For those of you who had this go over your head, the assertion is that since the GTUs was not made in extremely large numbers, then it is a sin to modify it in any way, and therefore the next 4 or 5 responses were supposed to complain about ruining the value of the car. The fact is that the GTUs has 0 collector value right now, and probably never will have any collector value, and therefore the next 4 or 5 responses stuck to the subject of the thread rather than going off on the wishful collector item tangent.

Also, there is the arguement that the GTUs is THE purist sportscar version of the RX-7. The fact is that all of the Series 5 cars have horrible suspension feel, and are heavy, which means that no S5 could ever claim the rights of being the purist sportscar, although the GTUs would in fact resemble this remark more than the other S5 models. The true purist sportscar RX-7 would be the 1Gen in general, the GSL-SE, the Sport, or maybe even the 88 GTU, depending on one's point of view.

Evil:
I agree with your bean counting, but in certain aspects and with limited applications the supercharged rotary has advantages. I've driven a 1st gen 12a with a 7" roots blower, Holley carb, and 4:1 rear end. At 50 mph there is no need to downshift at all, just punch it and go, much like a V8. The TQ is identical. From that same speed throw into 3rd and it's silly. However down the 1/4 (if you're into that sort of thing) it won't really perform as great, since it's dies off on the top. Individuals that autocross, have remarkable things to say about the low end grunt. And the EAA (Experimental Aircraft Association), has seen several uses, with Rotary powered aircraft, needing the low end grunt. It's not the simplest, the cheapest, or the overall best. But it does serve a purpose in certain aspect, and applications.

I dont know if i would get a sc, but I would definately go turbo
