Took this pciture of my car tonight on the saluda grade in NC

 

WOW!..that is sweet!!!!....

 

Did you put a kit on it or was that "all natural" gas to burn

 

street ported, 720cc secondaries, 255 walbro FP. Thats all my kit contains

 

damn............... u gotta tell me how u did that

that looks tight

Approximately at what RPM range do you start throwing those nasty flames??.

 

what kind of camera did u use? was the car sitting still, or did you just snap the pic at the perfect time?

 

heh...you should see mine...watch ill get a vid of it...
me goin down the highway...then booom ! biggest flame youll ever see...everyone says theyre HUGE !

 

yeah I wish I had a picture of the flames in the twisties...I can tell from the volume difference its a LOT bigger when Im moving. I think we may get some video up on the grade next weekend

 

I usually pop them off above 5k depending on how hot the motor is. That's pretty small flamage for an N/A. I have video of 4'ers I just need to get it on the damn web....

 

thats an s4 turbo II

 

yeah lol its a sf4 turbo II...

Did you do any 1/4's with that car? You have the number 45 on it?

 

45 is my autocross number. Have some 1/8 mile times from before the rebuild when it was running hot and all that...not terribly impressive. Ran like a 9.2 and then the leaking coolant line popped and left me stranded. It feels like a different car now

 

That pic turned out sweet. i like it

big flames are cool and all but everybody has seen em.
hell my old *** NA with straight exhaust shot a 3 footer once.

 

Just curious
if the exhaust is shooting flames that far out the back, whats to stop them from also going the other way and frying the turbines on the turbo, or even worse firing back into the engine? Its always been my experience, that flames are a bad thing.

 

I was saying that those would be rather weak flames if it were an n/a. I should've rephrased it.

Very nice pic though. on my video the flames ended up being 3 frames long at 30 frames per second. or 1/10th of a second long. I'm thinking you took this off a video.

 

Looks like a 2-3 second exposure on a tripod.

 

Looks very cool!

bingo

 

That's a incredible pic! Looks like something you'd see in National Geographic. (they're particularly fond of exposing for a period of time)

 

i love lo-light pictures with long exposure.

 

Sweet pic man, those flames are really concentrated like a blow torch or something, just don't do that in a gas station J/K

 

Generally they are not flames in the exhaust. There isnt enough o2 for the gas to finish burning, so it travels w/ the exhaust out into the atmosphere (where there is o2) so it lights up. Generally running rich (makes flames) runs cooler than running lean.

 

i'm getting a full exaust from the exaust manifold to the mufflers out of 2.25" tubing and some "Fireball" mufflers off ebay for my 87 GXL. will I get flames? do they shoot when you downshift or something or when you let off the throttle?

 

Hmmm.. could the 720's without fuel control make the engine run a little rich?

Looks like it to me...

COOL as hell though.


He he he: Showed the pic to my girlfriend:

Leah says:
sweeeeeeeeeeeeet
Sean says:
you like that eh?
Leah says:
I gotta admit that looks pretty cool
Leah says:
so THAT's what makes RX-7's so cool. do no other cars do that?
Sean says:
Not really. Damn exhaust valves get in the way.
Leah says:
so.... up for a top speed run anytime soon?
Sean:
I love you.
