How to shoot flames from exhaust

I'm the master of flamage. All you need is the aforementioned racing cat, several laps at Phillip Island and blow a turbo hose off at full noise in fifth at 240kmh. The resulting rich mixture burns in the very hot exhaust and results in flames 1-2m long behind the car. Continue driving long enough (say to the pit back entrance) and it can result in a completely melted rear bumper and tail light.

Plus I hate tail-gaters, before I just used to stop the car, get out and start yelling, now I just give it a rev.......the look on their face, priceless.

Well if another jap car is going behind you to closely and u do that, melt the core on their front mounf (if they have one) and you will be paying for it :)

Let's say a jap car was tail-gaiting me (they usually don't, its usually holdens or fords or people annoying me on purpose, I won't get upset if they're old, a mother, or disabled. But that's it!) and I let out a flame, and miraculously, it also burnt the FMIC on this car, how in the hell would they get me to pay? Make me pull over? LoL

How can they find out if you have a gutted cat?

Aside from seeing your car flaming on overrun, they'll smell it. The exhaust will smell a lot different to one that's filtering noxious chemicals like its meant to.

If you've been doing it for a while, there's a good chance bits of your bumper have melted (maybe not as bad as that NS.com photo, but I have seen the bumpers of some cars with "damaged" cats that have had small spot fires around the tip after a track session.

As for the "how could I get caught" thing, the mobile EPA guys have emissions gear and will pick you up in an instant.

If its just some random patrol car, they'll see the flame / damaged bumper and smell something weird. They might not be able to tell if you've got a punched-out cat by looking at it, but with the bizarre smell (and the sight of flames) they've got reasonable grounds to red-sticker you because your car is dangerously unroadworthy.

They'll tow your car to the RTA and/or EPA, where you'll get bent over.

as many people know, these forums ARE viewed by authorities.

Given the light of recent hoon publicity, just dont forget to state that the race cats etc are used only on track days and official race events. This is a pretty good forum with fairly sensible members, so talking about throwing flames anywhere other than on the race track isnt the best thing for the forum.

OK here is the vid. Doesn't take long (this was coming to turn 4 but the hose blew at the start finish line at PI) and can do some serious cosmetic damage. Forget about wanting flames!!

Nowhere near as expensive. I have the tailight replaced, the new bumper is here waiting for paint and fitting and the car is still sporting track spec ally sheet. About $300 to fix and I didn't miss a lap.

My problem was not seeing the flames, just saw the heat shimmer as I rolled around but that is expected after some hot laps. I was in the helmet, pulled way down into the seat and was watching for cars coming as turn 3 is 180kmh for me and faster for others. Flaggies didn't help with confusing flag signals. Ultimately no real danger, just cosmetic damage.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
