What does it mean for an RX8 to be rotory powered?

Edit: LINK!

I love that 'Motor'. 😀

Im a fan of the wankel motor, but far too many issues come up with it if your goal is to modify it. Not very reliable under high boost, and very hard to work on! I wonder if mazda will ever boost the RX-8...I hope so, but I think the issues with the RX-7 might have gave them second thoughts.

That's a pile of bull, I don't believe it, can someone show me a link to [/b] the manufacturers website that has thier specs on this engine, I am not going to trust the specs from a individuals website.

Is it powered by Oompa Loompa?

On a serious node, the potential for this engine is much greater for any piston engine. You can cramp as much power in it and it will not blown as a ppiston engine.

No, it's really called a Wankel engine. It was developed by Dr. Felix Wankel: Link

It's VERY different from a piston engine BUT very easy to modify and/or work on (especially easy to rebuild for a knowledgable mechanic).

True, turbo or supercharging is not easy to do 'aftermarket' - especially if engine longevity is a goal. Mazda can do it. 😉

It's a University web site, but if you really need proof and can't find it yourself.....

Actually, he's right. The engine is simply MASSSSSIVE, I think that's one of the keys to getting such a high thermal efficiency.

IIRC, it is an engine for giant ocean ships. It's been posted a few times here, you must've missed it.

I have asked this before, but I don't think I've gotten an answer.. how the FSCK do you go about machining something that gigantic?

Do they have lathes and mills that big? :Q The crankpins are as big as my torso!

 

Don't give me those rolling eyes DividebyZero, look at the BSFC (Brake Specific Fuel Consumption) on the link you provided, now compare that to the one provided by the University, two completely different rating, one at the University is .260 per horsepower per hour, the one you provided is 120 to 126 per horsepower per hour.

Quote from the first link....

Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake Specific Fuel Consumption). Fuel consumption at maximum economy is 0.260 lbs/hp/hour. At maximum economy the engine exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel in converted to motion.

Who ever wrote that page for the University doesn't know thier bunghole from thier elbow.

It comes with pedals. 😛

My friend actually blew one of those engines for pushing it to hard. Nothing special. Maybe handles NO2 better.
