Yeah jack ass! I like how you roasted your side seals. tisk tisk... I wonder what your apex seals look like. Probably burnt toe nails, thats what you get you stupid fuck and you not supposed to push rotorys past 11.5k rpms unless its a full drag car dumbass. Some people need to be shot for the shit they do to there Rx-7's man. Gay fuck!

Dude, chill the hell out, its a joke.. I was spinning it by hand, omg! Its not a 15k rpm revving engine, just your every day street ported 13brew! The title was a JOKE obviously. Did you even watch the video, haha?

@deadfaithful The point of the rx7 is as it's name says, 'rotary experiment'.

You guys give a lot of credit to an engine that has been around for over 200 years. Look you go and use your V8, I will use my engine, i'm just sick of you pistonheads always saying this engine needs to be tossed. It's new, and mazda/nsu own it. No other development is being done outside of them.

This design is 40 years old, piston engines have been around since the 1800's, no shit they work better.

@rotaryturbo88 cuz the rotary works more like a two stroke. It produces more power strokes per revolution of the crank than a piston engine. This gives the Rotary an awesome power to weight ratio compared to piston engines. A good way to compare the two engines is to double the rotary displacement. In your case a 1.3L rotary is comparable to a 2.6L piston.

@pdpdrummerboi he turned it three times how the hell did he fuck up his seals? u can rev rotarys to 15k on the street, ur gonna be buying a lot of gas but y not. jackass

[rotaryturbo88]

@deadfaithful Quick question, if the piston engine is more efficient then why in the same time period does a 1.5L or 1.6L piston motor without a turbo only make around 102-127hp but a 1.3L rotary without a turbo make 140-160hp, in fact, i think that the piston motor had to be 1.8L and bigger to finally pass that horsepower mark on stock production cars???

BTW i own an 88 10AE Rx7 as well as a 2000 WS6 so i like both but i dont know why one would say the rotory is less efficient. different, yes

[MrPervost]

@deadfaithful Yeah but with piston you have to convert up-down movement to a rotation movement with a crankshaft, which leads to a loss of power. In that sense, the rotary is much more efficient as the ''triangle pushed to the side'' is already in rotation. + the rotary has fewer moving parts. For the cooling it's obviously harder, but thats just a matter of a bigger rad and intercooler(if youre running a turbo setup)

@DwhNeo You my friend are a fail period. Ended. Noob. xD

[damonlandsdown]

@pdpdrummerboi your a dumb ass :O hahahaaha

[jeppoification]

@whatUsaybob RE stands for rotary engine

[updogs]

@i lol d

[iamxeddiex]

That was funny........ 99.9% of people are ignorant about the rotary motor. I have a rx7, it's more reliable than a v8 chevy and smoother.

LOL youre a knob
