Renessis Engine Working

[nswiss1975]

In deed a rotary properly built can rev 14 k,with no failure,most race cars add castor bean oil to the coolant and gas take for lubrication.

[drbaltazar]

each rotation gives 3 combustion per rotor your piston engine only gives one per 2 rotation if i recall correctly.that why you cannot ever rev a cold wankel.and you have to add 2 stroke with the gas ,plus change your oil every 3000 mile and if you race you might have to change it every 1000 mile.

[JuanPapaNicolao]

@drbaltazar ughh the 2 stroke oil deal

[Danglys1]

its all about the manual trans renesis. i got one. and its actually bad for the engine not to run it up till the 9k beep once every time you turn it on. maybe even a few times if you get racin ;)

[KaidoDrop]

A fine engine indeed

[REtiRO]

What is the difference between this and the rx7 13b... Other then it being NA..

[13brotary]

@REtiRO location of the exhaust ports  thats the only big difference

[leonardomoses]

THIS IS FOR ALL THE IDIOTS OUT THERE!!!

rotary fuel consumption: the reason why a rotary engine has a somewhat large fuel consumption is that every rotation there is fuel being injected and ignited, where as a cylinder engine is a 4 stroke engine and has a stroke in between power strokes where there is no injection and ignition happening.

[TFN8687]

that's cool.. i'm getting RX-8 2009 Renesis This year..

[akloy]

isnt this engine called rotary? rotary engine? like in the RX-7 mazdas?

[13brotary]

yes, where was your first clue Einstein?

[AznGunGrave]

Lol I have that song in the background.

[pottersrevenge]

RENSIS engines suck. 13B-REW is far better.

[quicksilverm27]

Man, I dont know about you guys but I hate people who talk like they know the real enginering in motors like these. I'm not even gonna argue on a stupid remark like this except for, the RENESIS is a great engine and is better than the 13B

[13brotary]

whats with all the negative on this post, EVERYONE who knows anything about the REW knows its better, the renesis is just a stupid attempt at good fuel economy- My 81 with the 12a gets right at 30 highway and you can't beat that with just side port exhausts

[pottersrevenge]

Thank you! finally somebody who knows what they are talking about. And wow to the 12A. I have not heard of anybody with one of those in quite sometime.

[havolia127]

i have a 2007 6-mt rx8, i think real hp numbers, at the "shaft" is more like 210-215 horse power for the manual, i think a supercharger, not a turbocharger is best for the renesis!

[MaxXximusGT]

dude I have a question, how's the fuel consumption on your mazda?

[CR00K1T]

RX8's get around 18mpg around town, and around 24mpg on the highway. My '78 (79 model year) gets around 15-16 around town, and around 22 on the highway. Yes, rotaries are gas hogs, lol.

[spawn77x9]

...start "floating" as soon as the cam goes faster and the springs cant keep following the bumps fast enough (for less than seconds)power goes down and damage can occur.The weak part on rotary engine is that the "apex" seal has to withstand all the forces (friction, centrifugal & inertia of the rotor)making it the weakest link. And the fact that pistons make more torque with less effort.

[spawn77x9]

Awesome engine design... efficiency at its best(my opinion),the "circular" movement of the rotor is the best cuz its as natural as it can be... allowing the centrifugal(helps sealing)/inertia(helps spinning faster) forces to HELP in the complete cycle. Unlike the piston up/down, inertia is against it half way and centrifugal f. is being "used" in a different component, the crankshaft. For a piston engine the faster it spins the harder for components to keep up, like the valves...

[AzrielStrife]

Actually they do have a redline at 8000RPM. The ECU won't allow revving past that point, but the engine will actually go farther i'm sure.

I drive a car with an earlier rotary known as the 12a, and with stock internals it's seen 9000 a few times while racing and the redline for that engine was 7000. it never gave me trouble, then the engine wanted to keep going, it just keeps making more and more power the higher you rev it.

[dsm664]

renesis stock redline is at 9k, not 8k. unless you have the 4 port automatic engine. the redline is set because of transmission failures above 10k, the stock engine is safe until 14k. but your clutch isn't.

[lululaserpiente]

250 hp?

[12valvepower1]

235-240

[Zerolagg]

I love it!!!

[foximissi]

most people with big ported rotary engines pull to about 10-12k, some P ports will go 14-15k. stock non turbo car is 9k

[veltpak6]

is this the NEW 16X 1.6L Renesis?

[TEUFELHuNDEN420]

That engine's a bad motherfucker, is it true they don't even have a redline??

[darrinjeffrieskilla]

I know they can wind out to maybe 9-12k easy becaues its a continuous motion not a push rod engine, but I dont know about no redline is there ant vids on ytube about that.

[striketalonx]

The engine itself can wind up very very high, its the actual drivetrain that can't handle that high of revolutions.

Mazda uses the Renesis in exclusively in the Star Mazda series, where they are allowed to wind up to far greater revolutions.

[spawn77x9]

No redline :) but there is no doubt that in some point the volume of air/gas mix in the intake port will not be enogh to compensate for the number of charges needed by so many revs (remember it charges 3 times per cycle) not to mention all other components that can't withstand so many rpms (cluthc... trans ect.)

[spawn77x9]

CLUTCH ha ha sorry

[000darkstar000]

COOL VID******THNX M8!
