What sort of figures are being got out of forced induction Rx8\'s these days guys?

Looks like the Pettit racing supercharger kit gives about 300bhp, which is where my OEM FC setups limit is before I start going aftermarket:

I\'d like a reliable 300 BHP from my FC... When I finally get it.

As far as RX8\'s go, are there many turbo ones about? Only famous RX8 I know is \'mad mikes\' nfs one. That\'s 4 rotor though not turbo, or is it turbo? Can\'t remember, most people boosting RX8\'s are using 13b-rew engines arent they?

Could be talking anus mind?!

The Pettit Racing Supercharged ones are making 330 bhp or so if they\'re well set up. Similar figures on the Greddy Turbo as well. All on the stock fuel system too. Esmeril Racing reckon they\'ve got 414rwhp out of theirs but it\'s not been reliable. Mad Mike\'s RX8 is a 20b with a T51 and about 700 bhp. Because the RX8 motor has higher compression rotors it doesn\'t take kindly to big boost without taking it apart and sticking lower compression rotors in. Also there are issues with port cooling at high boost on the stock engine. A reliable 300 bhp is relatively straightforward on a stock motor but more than 400 bhp and you\'re looking at significant internal work on the motor.

300 rear wheel or flywheel buddy?

Pettit reckon their supercharger produces 280-290rwhp on 95 octane but I am pretty certain that Tango Tony\'s 8 has 330 rwhp running the supercharger with an HKS F-Con 5. California Style\'s one is probably about similar levels if not a bit more because he\'s got a Pettit Racing ported and blueprinted motor in his and is running a very unrestrictive exhaust. But they\'ll be running higher octane fuel. Any higher and you\'ll need bigger injectors.

Anybody know what power figure Exiled Viking has? His is a Supercharged 8 and looks amazing to boot.

There is the JIC RX8 D1 GP car pumping out 520hp and 370 ft/lb, but I believe that it\'s a REW rather than an MSP engine.

Thanks buddy :Thumbs-up

JIC RX8 D1 car had a 13b-REW.

Exiled Viking was Tango Tony, he\'s changed his name a couple of times.

jetpilot · June 20, 2011, 07:31:31 PM

So which part is the limiting factor for more bhp, high compression rotors?

Arnie_O · June 20, 2011, 08:06:52 PM

There is a guy over on the RX8OC thats just had some more work done to his and says its potting down over 400 on a high boost setting

What sort of power is that then, if you know?

I believe so, but also the pathetic side exhaust ports are big too wimpy for higher temperatures??

Will66 · June 20, 2011, 08:18:20 PM

Tony\'s car had 330 hp.

The cooling around the exhaust ports is insufficient to cope with big boost without a bit of modification. I know pettit racing\'s engines are modded to cope with this.
