coolest or oddest motors

[ironman]

I thought it be just nice to see some motor only pics that we have for our kart.Always nice to see different styles to help others decide what they should go with, and put up specs of motor with pictures.
this would really help alot of karters decide what they might want to use.

opposed piston engine

always thought that these were neat engines
radial engine

love these guys. lots of hp out of them
turbine

aw, i thought this was going to be a cool or odd any motor. there are some weird ones out there. specs:

factory cam, piston, crank, block, bolts, fly, rod, valves, rings, gaskets.

aftermarket: carb, spacer adapter(half of an animal spacer), spacer(1inch heater hose), rockers (1.3), lash caps on both valves, exhaust pipe, 8* key, 160 head (mild port, and chamber 'tuning').

oil: 5w30; gas: 92 octane(just cause i want to, not have to)

I think this is a odd botch of an engine, sorry but dont think anyone could put it on their kart. i have never seen one in realife but i will someday.its the rotary engine that the mazda rx 8 uses. it was originally used in the 1967 cosmo

heh that's what you think, they have been putting rotary engines on there for a while
lots of power in a very small pakage

 

[mrfreyguy]

I'm pretty sure that some vintage sleds used a rotary (wankel) engines. It's a cool way to get so much hp out of something so small.

 

[KieranM]

do you know of many cars that use it?

 

[TurtleMann14]

rx8 is the only one i know of

 

[KieranM]

do you know if they still use it in the new models?

 

[mike75925]

as to cars, the rx7, rx8. mazda made a few trucks using the engine. suzuki made a single rotor 500cc rotary motorcycle, van veen made one on a moto guzzi frame. there are other. the 787 race car uses a triple rotor. aixro is a 250cc kart engine that makes 48hp. but it costs around 5k.

 

[TurtleMann14]

yep, 2010 rx8 has a 1.3l producing 232hp

the early 1970s arctic cat panthers used wankel rotary engines, I saw a youtube video of a wankel powered go kart a while back.

 

[KieranM]

would they be easier to maintain than a straight/flat and a v

[mike75925]

they are easier to tear down, but it's 'rings' or rather apex seals and side house gaskets don't seem to hold up for very long when compared to regular rings.

 

[KieranM]

would you think there is a big performance parts market for the wankle or is it best left alone.

 

[bajagokart]

with some tuning those old rx-7's with a 1.3L rotary made a frick load of hp! ive seen them with 900hp and greater

 

[TurtleMann14]

more of a race engine
not very good for the street

especially since there is a certain way you are supposed to start it and shut it off

 

[mike75925]

my uncle bought my cousin an '86 modelrx7 for $250. the carb was like 400 new, and the exhaust was like 2500.
