Just say no to pistons!
Rotary's are the way forward 

[paul_gt4]

yeah if your fine with spending a fortune on oil and rebuilds they are. Love the noise of the rotary still though and would love an RX7.

RX8's are cheap now.. just the cost of oil and petrol that puts me off

[paul_gt4]

you forgot about the price of rotary tips and labour for putting them in jeff. My woman likes them but she wants a DC5 ITR next.

you going to make me jealous then....... friend has a gorgeous black one over here, sounds like a motor bike

[flyingtele]

theres a guy here who has a black rx7, recently had a full rebuild and a tune and is now making upwards of 400 hp

[paul_gt4]

yeah my mates is the same, in and around of 400bhp, they are capable of well more than that though

Didn't they sort the Apex tips out on the RX8 engine? I know from when I had my old RX7 a lot of the other owners were retro fitting RX8 tips into their engines...
I'd love another, fuel wasn't too bad on it and I never had any probs with the engine....Maybe I was lucky? Until I wrapped it round 2 lamp posts....

What's the power delivery like on these *BLEEP*el efforts? And what max rpm is the norm? Just interested is all.

Awesome in a word Frikkin Evil my pal used to have RX7 with around 320bhp and it felt a lot faster pins you back into the seat esspecially when the second turbo kicked in  he also went sideways everywhere lol

[Frikkin Evil]

Nice. I see the swear filter doesn't like the word W@nkel

Something that small could spin up to ~tens of Krpms but not much more I suspect, power output of those is currently 2.5W - you could produce more power by standing in front of a wind turbine and shouting at it 

Theres an RX7 (1984) being given away by someone where I work, kept under covers in the drive for 2+ years but running fine last time it was used. No takers as yet.

[flyingtele]

would be awesome to put say four of those little motors together into one, and use it in a very small rc car, would go nuts!
