I have a question about stock exhaust
I hear flame out of exhaust is a trade-mark for rotary engine
I saw some of other fellow owners throwing flame out of their non-stock exhaust pipe.
I was wondering if it can still be done with stock exhaust.
Are there any stock exhaust flamers out there? if you are, can you teach me how to shoot out flames?

Thanks

From what other people are saying you have to keep the revs above 6k for atleast 3 minutes....then once you've done that, strat revving your engine up and check if there are fireworks...havent done it my self but heard of other people doing it..

That can't be good for the car though?

How much gas did you burn? And do we know if it's damaging to the exhaust? I would think it shouldn't be. Above 6k RPMs for 3 minutes isn't that excessive. I could do that easily on an open road driving agressively. Also, were you driving at 6000rpms for 3 minutes? Or just sitting in a parking lot in neutral?

Just take your 8 out to a highway and get it up to highway speeds, keep the gears low to keep your rpm's high. After several minutes gun your engine out on the highway, or take it to a parking lot and gun it a few times, you should see flames. If not, keep your foot on the accelerator a few minutes and the gun it again. I havent done this with stock exhuast, but should not be too different.

it's just caused by a very very hot exhaust and some unburnt gas flowing into the pipe lighting off ... my dad had an old 57 chevy that he rigged up with a spark plug in the tailpipe - you pressed a dash button to repeatedly set off the sparker while revving the engine - as the revs died down you'd get this POP POP POP sound and several feet bright orange flame would lick out of there.

I'm sure the hydrocarbon emissions on that car were close to a million times higher than that of an RX-8, however. Also, the flames eventually blistered the paint and bubbled the plastic on the taillights (if you recall, the exhaust outlets on an old '57 chevy exit through the bumper), so I'd be careful with that considering the -8's plastic butt.

Seems like an awful lot of hassle and work for a very cheap thrill. A double bean burrito and a bic lighter is easier.

Yes, I agree, an awful lot of hassle and work, BUT, I have managed to do it several times on the highway unintentionally, just driving aggressively, and it is wondrous at night. Doesn't take long to get a line of cars following you to see if it happens again.

....then again, maybe I just like the attention..... :o

OK, now tell me how you guys see flames in back of your car when driving. You have like a camera atteched or what.... I understand someone recording you or your friend doing it on a parking lot so you can see it but other then that how would you see that you are bursting flames out your exhaust when you you are driving the car? Iknow you can hear backfire slightly (but other then that idk)?

I do love that "bup bup bup" burble you get off throttle on engine braking ...

I live in Bay City, Texas, southwest of Houston. Being out in the country, it is VERY dark. When the 8 shoots flames, I can ocassionally see the flame in the side mirrors(the glow, not the actual flame), no joke.

On the highway, it isnt so noticeable since there are headlights shinning on your rear, BUT, the ocassionaly POP and the few cars that hover around my tail tell me that I just threw another flame. It actually happens often in my 8, hopefully thats not a bad thing. I havent noticed any damage to the plastic pieces yet.
