maybe someone here can enlighten me
why some ferraries make those cool flames out of their ****?
why not Pcars?
can we retrofit something to make our cars to shoot flames?

 

Watched Miami Vice lately eh?

I think those are effects kits, IIRC I've seen them for sale.

 

Seen the mostly at classic car shows, spark plug in exhaust extension and feed rich mixture, energize plug!
Would I do it on my P-car....No way!!!!!!!!!!!

 

LOL

guilty as charged,,

they look so cool though.
IIRC? ok I will look them up.

 

I have seen it in 997TT

 

i followed a gorgeous F40 recently and it was quite cool in the tunnel!

 

Its not from a spark plug in the exhaust. Sure, it can be done that way, but Ferraris and Lambos have a tendancy to do it. Its just from a rich air/fuel mix and not all the fuel being burned before leaving the engine, and the free flowing exhaust really helps. You really notice it on cars with the cats removed.

Some good examples:

I thought that phenomenon was usually from turbocharged motors when waste gate(s) were opened. Typically when you decelerate into a tight turn.

Putting a spark plug in the exhaust is a good way of destroying your exhaust system. I recall blowing the muffler on my older sister's vintage Pontiac by quickly turning off/on the motor while putting the gas pedal to the metal. It made quite a kaboom until the muffler decided to fall apart. She still doesn't know why she had to replace it. Some things are best left unsaid.

 

Oh so true and well stated but it's also due to the cat structures, secondary air pump function, and the placement and function of the muffler.

This is also partly the reason for the valves on the oem mufflers (as well as some aftermarket units). They keep some of the gasses within the muffler to ensure they are fully burned at lower RPM's.

So there can be a bit of richness w/in the exhaust.

I would think that rewritten ECU's optomize the burn so well that there are fewer incidences of flames.

I have never experienced it on mine.

 

Straight pipes will give you flames...

helll yeahhh

 

MovingUp - "IIRC" = "If I Recall Correctly" - I have a tendency to use abbreviated forum speak. JMHO, YMMV, TIA, OP, SO, PITA, WTF, ROFL etc..... ;p

 

..That GT3RS in the vid sounds ultra-wicked!!

 

I have highflow cats with no mufflers... No flames

 

Me too

Straight pipes are just headers with no cats or mufflers.
