if that' show loud they are off the showroom then nobody would buy them.
That is not a stock or lightly modified engine.

They do have low torque. I can grab some random video off the internet showing an all motor CRX running a 12 second quarter mile. That doesn't mean that Honda makes high powered 4-cyl engines.

a 280ZX non-turbo can blow away a 1st gen RX7 without even trying. ...or with trying

 

I had a 87 rx7 and it had no low end, but get the RRR's up... hold on

 

torque means nothing after the firs 2 seconds into a race. or unless your towing, and yes rotaries use a good amount of gas, but now one said they were GAS efficient.

 

I had an '87 also. Fun car! Had a power band like alot of sportbikes...all the power on top.

 

I liked my RX7, but it's that damn seal that goes out, can't leave em parked for more than 6 months or so, or the seal might go bad... then if you can find someone to fix it,... I'll keep a Z, one day, I'll take a RX motor a part and try to put it back together, maybe it will run... LOL

 

And no one said anything about any other kind of efficiency either. And when there's lack of specification, and we're talking overall "efficiency", then it's still nothing special, because amount of fuel consumption is a part of the engine formula. After all, efficiency is just getting the greatest output for the least amount of input.

Also, races are frequently won or lost in the first couple seconds (especially drag racing), so don't be so dismissive about the usefulness of torque. It's also what helps pull the car out of corners too.

 

the only goof rx7 is an ls1 powered rx7 other then that and your wasting your time.
