RX-8 Specs?
RX-8 Specs?
I was watching some race on SPEED and there was an RX-8 running with 911s. It was faster on the strait. They said it was running an RX-7 engine. Does anyone know which engine it runs, and the specs of it. Like the HP, Torque, Accel, Top Speed, and other stuff.
Also, try this site: http://www.speedsourceinc.com/
They have a full race program they run through their MoTeC engine management. Race exhaust, gutted interior, full race suspension, 107 octane w/synthetic pre-mix. I'm not sure what exactly you want to know...
Right, because they only run an RX-8 engine. And that comes directly from Sylvain Tremblay (SpeedSource owner) and Dave Haskell (SpeedSource crew chief) who built these race cars.
just because the announcer said it doesnt mean its true. I hear it all the time when i watch sports..
they call the sports player by another name. For example: The announcer called Amare Stoudemire, Salim Stoudemire. As we all know, there is no salim stoudemire on teh suns so obviously it was a mistake. Same applies with your RX7 comment.
Now if you prove me wrong about the 8 u saw racing with the 7 engine. ill eat my words.

Now that explains everything...you were watching Rolex GT qualifying! SpeedSource runs that RX-8 and it does have a 20B 3-rotor. It is not an RX-7 engine. The first 20B's came in the old Mazda Cosmos. The new 20B is actually a modified Renesis. Mazda MotorSports developed this engine!
Here's some video of it in action at VIR!
