What If...

  1. Re: What If...

    it would be a lot heavier, thats what

    one of the biggest advantages of the rx-7 is that it's so light and balanced, it handles like a dream. a huge 4-rotor engine would mess things up

    you can get over 500hp from a 2-rotor anyway, some modified rotaries have as much as 700 but they aren't very streetable.
     
  2. Re: What If...

    Hence why even the 3-rotor really needs to be pushed back for even weight distribution. 1000hp is achievable with that combo....

    There already is a 4 rotor rx7. In le mans it was the only japanese car to win lemans.<!-- Signature -->

    That car was an LMP (Le Mans Prototype), that amazing 4 Rotor engine, while essentially a doubled up 13B(RX7 engine), was never in any production car. The biggest production rotary from Mazda was the 20B
    2 litre, 3 rotor engine from the Japanese market Cosmo.
    By the way, i hear that was one hell of an engine with lotsa low end torque(in a rotary?!?)

    yeah the good old 20B! its currently in one of the quickest street rotors in australia at www.rotormaster.com.au

    I think the series 6 with it ran an 7.88 last week or the week before.
     
  6. Re: What If...

    Peter Farrell Supercars sells an RX7 with a highly tuned 20B in the USA, an article in Car & Driver lists it at 600 bhp and 450 lb-ft. I'd buy one, but my wallet isn't 80 thousand dollars deep.

    i doubt the low end torque thing

    it's peripheral ported - those things make next to zero torque under 6000rpm, but will kick in like it has turbos and become a monster all the way to 12,000 rpm+

    peripheral porting was so powerful on race rotary engines that its been banned by a lot of regulations.

  12. Re: What If...

    Actually, the 4 rotor isn't significantly heavier that the 3 rotor or 2 rotor...You'd hav to place the engine differently but it would do it's part. the 767B was 1500 lbs with a 4 rotor..
     
  13. Re: What If...

    The Mazda 787B has four Rotars.
