RX7 Super Turbo
Does anyone know if there has been a super turbo rotary? ya no.....supercharged for low rev boost, with a turbo charger kicking in higher in the rev range, like the old NISSAN Micra Super Turbo (dunno if u know it, the only factory car to my knowledge to has this). Just thought it would be pretty sweet to do this. A blown rotary turbo!!!!!
Any feedback???

Today, with the properly sized Turbo or supercharger, you get the same benefits, with half the complexity.

so what your saying is it's not too hard to do?

the guy with the mister 2 said it was an awesome setup, the supercharger boosts instantly to like 6 psi then after 6psi the turbo takes over up to like 14 psi i think he had is set...
******* aswesome concept

The old Lancia Delta HF Intergral used this for Group B rallying.
That car dominated all, including the drivers. It was more of a "let the car do what it wants, and maybe it will take mercy on you".....killed more rally drivers than almost anything..that car alone got Group B rallying shut down forever...
But man, it was such a great car...
I'd love to see it on a rotary...

The old 2 stroke diesels ran blower/turbo combos because they required positive intake pressure to run.At startup and low speeds,the supercharger provided mechanical supercharging at rpms that the turbo could not.At operating speeds the turbo took over.It was more of a neccesity due to the design of the engine,rather than the inefficency of the turbos of the day.
Theres a Camry V-6 powered MR2 that runs a blower/turbo combo.Its WAY,WAY, powerful,but it could still be plenty strong without the extra work of installing the supercharger.
Yah,its cool....but in the end its not really neccesary unless your deathly against any turbo lag.

That is quite possibly the worst idea i have ever seen. Everyone, even my hampster, knows that it is hard to tune, makes less power because of the drag of the supercharger, and just creates more weight and crap to wire in. Get a 4 rotor.

the supercharger has a clutch in the pulley that disengages when the turbo makes the same or more boost. i would complain about the backpressure the turbo still presents while spooling up.

I believe HKS employed its TwinCharger system on the AW11 MR-2. It was pretty insane, but I believe the boost control of the day made the car out of control. Not worth it, IMO. Now, if only someone could combine an axial-flow supercharger and a turbocharger; that would be awesome .

Mazda used twin charging on its diesels at one point ... its a very odd setup with a belt driven squirrel cage fan type blower that is also driven by the exhaust on its other side. Mad ! I think its called a comprex supercharge and its a really odd setup and has somthing to do with pressure waves too as the compressor side is open to the ehxaust !!
... here's a link or two

The advanges of this were stagering, considering you'd have NO lag at all, and you could have around 90% of your HP/TQ at a very low RPM, which could pull you around corners with ease, or get you out of that tight situation without worry.
4 rotors are meant mainly for straightline speed...
