Title: 400bhp RX8
Post by: Mikey22 on November 01, 2012, 05:57:36 PM
Hey guys,

not normally my section but i wanted to ask a few folke in the know. A friend of my gf used to have an Rx8. We were talking the other day about my 7. He stated to me that he knew someone who had a mazda speed rx8 who managed to get 400bhp from it without the use of a turbo. Is this possible?

he said that the mazdaspeed rx8 had titanium tipped light weight rotors. i just cant see those figures workin out.

what do u guys think?

cheers

Xtreme rotaries make just a smudge over 350HP with quad throttle bodies and bridge ports, revving out to 10,500 rpm, so 400 seems a little too high IMO unless its a 3 rotor then it would make that easily.

Well he said that it had a triple rotary 13b, which i know is a complete load of s@#t but there we go.

He said it was N/A, that\'s why i couldnt understand it. He said the only mods were injectors and remap. I was totally confused. Seemed to think the only \'special\' mazdaspeed rx8\'s were in yellow.

I\'ve never heard of an rx7 or rx8 having a 20b as standard? or am i in the dark on that one?

lmao i knew it!

I\'ve seen the one he\'s on about too, its a 231BHP standard. I know he didn\'t throw that much money into it to reach those sort of figures.

350bhp With Supercharger Is Possible With Out Any Engine Mods But The First Rule Is Do The Brakes First !!!!

400 bhp on a two rotor without FI is a big ask.  I daresay he\'s yanking your crank.

I hope you laughed in his face for claiming such tosh
Did you happen to meet him down the pub?

The only Mazdaspeed RX8\'s I heard of where a JDM special with slight tuning mods and remaps... Not making the figures your mate claims

tbh hes a gsi kid. think sticking a redtop in anything is best. he thinks his dads l200 could beat my rx7 because as he says \'its rapid!\' despite weighing nearly 3 tonne or more.

i held my laughter till i got in the car!, thought id be nice as it is my gf\'s friend but hes a lot younger than me. so think he wanted to show off.

reminds me of that video on youtube of the lad who had a gen2 rx7 and he thought it was a 5 cylinder. lmao!

Motorsports Development today announced the continuation of its partnership with Florida-based SpeedSource, Inc. to produce a Grand American Road Racing Association Rolex Series GT-class Mazda RX-8. Set to make its competition debut during the 2006 Grand Am season, the Grand Am GT RX-8 is based on a tube-frame chassis jointly developed by SpeedSource and Riley Technologies, and powered by Mazda’s three-rotor 20B rotary engine.

“Mazda has always been a leader in both amateur and professional motorsports,” said Steve Sanders , manager, MAZDASPEED Motorsports Development. “Developing a Grand Am GT-legal car is the next step in expanding our already successful Grand Am program. And expanding our support to competitors interested in racing the RX-8 at the next level is a logical extension of our motorsports program.”

Renowned chassis developer Riley Technologies worked closely with SpeedSource to design the steel tube-frame chassis. A six-speed EMCO sequential transaxle puts the three-rotor power to the wheels.

Downing/Atlanta was responsible for developing the high-strength carbon-fiber body panels that mimic the shape of the Mazda RX-8 street car, except with a no-nonsense racing stance. In addition, the body develops considerably greater downforce than the stock body would, while minimizing drag.

The 20B three-rotor engine is the cornerstone of Mazda’s Grand Am GT RX-8 program. With its compact size and light weight, the rotary engine brings with it a vast history in sprint and endurance racing. Revving to over 9,000 rpm, the 20B rotary engine will sound quite unlike any other engine on the grid.

Coordinating the development for SpeedSource, Inc was team owner Sylvain Tremblay. Tremblay and staff are an experienced Grand American team, with a long history with Mazda and extensive knowledge and experience in tuning and racing rotary engines. Tremblay’s SpeedSource team took top honors with their Mazda RX-8 in the Grand Am Street Touring division, winning the driver’s and manufacturer’s championships.

Being able to offer these high quality components to race teams from a single source simplifies the entire build process. Components ranging from a bare chassis to a complete car can be purchased from SpeedSource. A complete car, including chassis, full drivetrain and engine management system, suspension, wheels, tires and bodywork is priced from $280,000. Comparable racecars are priced higher, yet may provide lower performance.
