In general I consider superchargers to be better for low end torque, while turbochargers are better suited for high rpm horsepower.



I chose turbocharger since we are talking rotaries though. Rotaries in particular seem to go well with turbochargers since it capitalizes on the high exhaust energy that rotaries have.

 

The only supercharger I would consider putting on any rotary would be a centrifugal type. They would be easy to fabricate a bracket for and are as easy to intercool as a turbo is. They do have a little bit of lag like turbos do because they essentially are a turbo that is spun by a belt rather than exhaust gas.

I think that Maria Motorsports used to sell a centrifugal type supercharger setup (wonder why they stopped?).

 

I've always been told that on a 6/7/8000hp top fuel car, the s/c takes over 1000hp to drive. Talk about parasidic drag wowzers!

 

question. How many companies acauly make these things for rotaries? i meen, with stock turbo cars you generally dont see very many for good reason. Stock S5 13b's generally dont have that much turbo lag, compared to other cars of the era like the toyota supra, so i dont see much of a point fabbing up some s/c setup when you could just get a decent setup on what was stock a turbo

 

theres also the fact of noise



NA's are ******* loud.

on TII's the turbo acts as a muffler pretty much, so it quiets things down.

 

Yeah it seems it's nearly a waste not to turbo a rotary, way too much energy in the exhaust - some of the 20b's posted here have turbos that look like they're nearly as wide as the engines they're on.

 

So your saying that when i turbo my na im going to lose one of the things that i like the most about my car.

That great loud high revved sound....hmm maybe ill look into super chargers then.

 

the turbo acts as a muffler.



with the exact same exhasut on a na and a turbo, the turbo will be a little quieter. but im not saying all turbo cars are quiet.

 

you're taking the energy that would go out the exhaust as noise and using it to spin the turbo

 

Who is still making supercharger kits like Nelson used to have for the FC?



Would like to doe something like that for the vert. and when time comes to smog. just take it out. That's the only + thing I like about sc and the instant torque so i can make a heavy car take off the line a little better.
