Fire from exhaust.

[ninjak84]

Out shopping today, I heard 2 geeks (who obviously don't drive) complaining about how fire never comes out of real car exhausts, and that the whole idea is crap.

WRONG.:angryfire

Just because fire doesn't come from your 116hp car, doesn't mean it's crap. Try watching movies of 400+hp boosted cars driving at night, and guess what you'll see when they shift gears? Yep, fire. Ever watched the GT series races? The ones where Porsches, Lexus', BMW's, Ferrari's, and Mercedes' race? Take a wild stab at what comes out of the exhaust every once in a while.....Theres also ways of actually making your 116hp car shoot flames, and you can do that by hooking up a set of spark plugs to your exhaust. Not recommended, but you can do it. I don't know if flames means you are running too rich, too lean, or just right, but for all the non-believers out there, it DOES happen..

[SpeedRacer1]

Taking out your catalytic converter and running rich can definately help out. Misfire systems for turbos also help.

Ive had my cat off for a while on my boosted sr, and my bud called me up 2 min after I dropped him off one night to tell me he saw flames out my muffler.

I was as surprised as him, my car does not run rich.

[IvanS13]

You shoot flames (if you are running really rich) when you backfire... rotary's do it all the time.

what about thore brake rotors from the leman races that light up as they go from 160-25mph in like 2 seconds??!! that is bad a s s !! will drilled and slotted rotors that we can get (brembo etc.) do the same thing?

[ninjak84]

They should do the same thing. Street driven monsters (Lancers, SKylines....) in Japan have crossed drilled rotors, yet when you are tearing down the road and slam on the brakes, it'll light them up.It's just because of the immense heat involved in stopping a 600hp car really quickly.

[stickgoat]

Rotaries are notorious for shooting flames. Especially turbo rotaries.

I've seen it happen numerous times whilist hanging out with RX-7 people. Really not a big deal to me anymore.

[UncleBen]

i think that would be pretty sweet to see. especially in an RX7. i've seen those GT races and stuff where it happens there, but never on a street car. i would love to see a RX7 take off and fire shoot out the muffler. SWEET!!

[240sxrunner]

I have no cat on my 240 with all 2.5 mand. piping. Bad choice i am puting a cat back on but wow sometimes the flames come out like more then a 1 foot when i shift. thats what my friends say. i have all straight pipe with magna flow turbo muffler.

[89sxRCR]

friends 240z v8 swap used to backfire all the time, and along with the gunshot sound flames would spurt out... it was pretty cool, it made people on the street walking hit the floor. He corrected it later...but it was dayum cool

[PabloHoney]

Rotories (especially turbos) tend to do it more often because of the trailing spark plug (two plugs per rotor) igniting the unburned fuel still in the engine, which usually likes to shoot out the tail pipe.

[fryrice]

Yep, the mullet mobile shoots out fireballs all the time!! Especially on cold nites. I also have no cats, but do not run rich. I'm on the edge of being too lean. Regardless, I still shoot flames.

The fact that my exhaust dumps underneath my car before the rear axle helps in the fireworks display.

[jemil118]

If you put spark plugs on your exhaust, you better have some bite to back up that bark, otherwise I say it's kind of cheesey. Now if you don't do it on purpose, then thats another story....

[volthause]

race car fuel injection is usually programmed to run rich on over-run (off throttle engine braking) to keep cylinder head temperatures down. the temperature of the exhaust ignites the unburt fuel and voila.. flames.

[ninjak84]

No. But heres a lesson:More horsepower makes cars go faster. When a car goes faster, it takes more strength to make it stop faster. So you can imagine that when a 600hp Lancer is flying down the highway, and slams on the break, the rotors are going to glow from the heat involved. When a 90hp Civic is zipping about at 90miles an hour, and slams on the break, there is no glowing. It's because the Civic is slower, and the Lancer is faster.

[thatguyin240]

My 240SX backfires toooo loud sounds like a heavy deep subwoofer boom and many smaller high piched pops. Observed from my friends in the back they complain my exhaust lightning up when it backfires :p

but then sometimes its a pain. Backfire near or right infront of a cop car isn't that funny.

[wingzero]

You could buy a Bee*R rev limiter w/ misfiring action. Basically just cuts the ignition so you load your system with fuel.

[Megaseth]

yeah, i was reading about that. rev limiters on cars cut fuel. the bee*racing one cuts spark, and then starts it up again. i was reading about cars with no cats, can get like 2-3 foot flames. pretty cool, especially if on a skyline.

[MAXIMUS Nismo]

but me thinks the coolness factor wears off after awhile if all u have is flames for show. Now flames for go are a different matter all together.

[APEXi240]

OH NO! Brake arguements...time to bust out the tylenol.You can make any cars rotors glow. Except for drum rotors (I assume...).

Race fuel would also make your car backfire, spit flames more correct? My friends car doesn't make all that much power, but he used race fuel, and a different ecu, and there wasn't FLAMES per se, it was more of a little blue halo, and a big *** backfire.

[ninjak84]

Oh hell no. I never said cross drilling had anything to do with glowing. They are designed to reduce the heat generated from braking. You can't argue that.

- The driver makes the car go faster? Shaddup and go back to sleep. Oh no wait, you're right, a stock civic can beat a modified skyline....

You're sounding lame. You absolutely cannot deny that a higher horsepower car will generate more heat from slamming on the brakes at a higher speed than a slow arse car. It's proven. Unless of course, you're right and the rest of the world is wrong. :rolleyes

[Nismo Sr22GT]

k car, what he probably means is that the rate of accelaration of the car, then suddenly stopping, you are putting a s h i t l o a d of load on the breaks bcs it not only the car's speed, or the weight, but a combination of both, and the pistons pushing the pads against the rotors so hard that its only natural that they will light up.

[ninjak84]

That's what I've been saying! Not once have I mentioned the weight of the car.

[Nismo Sr22GT]

ninja 84, u got aim?
