Anyone seen a exhaust flame kit on a mini? I've seen a video of a mini on a dyno with a tiny exhaust flame which was 'natural'. I'm not wanting to do it to mine, but I'm just curious.

 

contact nitrominis

 

The car was not running a cat if it did it naturaly. because the cat processes all the unburned fuel exiting the exaust system and being igninted on the tips....
So if its doing with a cat theres a extra injector or fuel sorce with an ignition source somewhere else(cheating) thats causing this. However I being i dont know where you live. but its more than likely Illegal.

 

omgg that would be amazing to see flames shooting out of a little mini cooper!! ; )

 

I have had a home brew FLAME system for a couple years that put the Fast and Furious to shame.

VERY illegal for show only.
Warning do not stand less then 15 feet behind my MINI.

My system does not interfere with the fuel or ignition system. It is stand alone is the only way to go.

 

Any more details on how you hooked it up? Pictures? Videos?

 

I'm sure that onlookers would be greatly amused as they watched you melt the plastic bumper cover...

 

No it does not melt either. It gets a bit hot stationary but not any hotter then the normal exhaust.

The only problem I have with it is the exhaust velocity. I am working on increasing pressure without losing the flame. Anything over about 40 mpg and the flame out. To much air not enough fuel. If I were using gasoline this would not be a problem. I really do not want to set someones car ablaze behind me.

 

No it does not melt either.

When stationary I get a nice flame but over 40 mph the increased exhaust velocity will kill the flame(flame out). I am working on a way to increase pressure with rpm. All this would not be a problem if I were using gasoline. But I do not really want to set ablaze the guy following me.

 

So, when can we get together so I can get flamed up? The flame thrower has got to be one of the coolest mods possible.

 

exhaust flame mods are highly, very, super, extraordinarily illegal, and act as cop magnets as blood to sharks.

'nuff said.

 

As it has been mention and I also said that a flame kit is very illegal.

I never use it except in private sanctioned shows and I always obey the posted speed limits. And I never lie about my age.

Fracky, yes it is one of the coolest things on my MINI along with my LED NOS purge and my remotely operated exhaust cut out and can't forget my ocsillating LED scoop light.
Thank heaven I have many CHP buddies.

I tied into my LP Augmentation system using a separate line into the exhaust via a one way valve. I use a conventional coil and a tail pipe mounted spark plug to ignite the gas. Very safe and controled by a momentary switch.

 

Ok so the more I think about it the more I like it. I know it's illegal and some people think it's tacky, but it's my car so what the heck!! I saw some posts of people that have them. Could we get some more info on what you did, maybe a few pics too. I have a rough idea of what to do, just some guidance would be appreciated.

 

Not so sure I'd like that... seems like a waste of fuel and possibly a little dangerous. At least a backfire potential, no?
I'm so picky about my MCS tailpipes that I don't like seeing the soot buildup. I wipe it off with a tissue virtually every day. :-) I like clean pipes.

 

I'm not too worried about the fuel and soot. The backfire potential I've been doing some research on b/c I was worried as well, but it seems that if you do it correctly the velocity of the gases carry it out the back no problem.

 

haha fn sweet!

 

Post a pic! Video is better. I know old hot rods do this trick. It would be cool to have a small camping LP tank in the back for this..

On a side note.. One day years ago I was on the highway in a friends CRX Si. Doing about 75 a Mustang GT500 came along side. Then shifted into a lower gear and completely dusted us. It was SO fast.. And it was at about 7pm so there was still some light but the thing I remember most about that car was the blue flame from each tail pipe as it just took off.

 

A good concern if we were using gasoline. I use LPG and three safeties. All need to be manually opened and shut automatically. There is no backfiring from LPG. And the by product of LPG is carbon dioxide not monoxide,and Hydro carbon. So what that means is no soot and environmentally clean.

The coil and the parts attached to it is the heart of the FLAME system

This is a plate I made and is mounted under the rear seat delete that also control devices .





Bang110 good thought about the small BBQ LP tanks. I use them with a modified valve but they do not give enough pressure long enough.

The problem is using larger tanks is they are under current **federal regulation with OPD valves. These new valves reduce the volume and pressure via the OPD valve. So you have to modify them to get full tank pressure and volume.


**The 1998 revision of the National Fire Protection Association's Pamphlet 58 requires that all cylinders, 4 lb. (1.8 kg) through 40 lb. (18 kg), fabricated after September 30, 1998 shall be equipped with an OPD valve. Further, any cylinders of these sizes that are re-qualified must be equipped with an OPD valve. If your cylinder is over 12 years old, it must be re-qualified before it can be refilled. It will be retrofitted with an OPD valve at the time of re-qualification. You can find the date of manufacture on the upper collar of your 20# cylinder. Effective April 1, 2002, no cylinder will be filled unless it is equipped with an OPD.

 

Thats quite a setup. I didn't think there was that many electronics involved. You do all that yourself?

 

OK so judging by the pic from above. you clearly have a nice setup. You also stated you have 3 safeties. I have pretty much figured out (by your pic) how to set that portion up except the minor details, a wire schematic (napkin works) would be helpfull too. What safeties are there and what is your ignition source? also stated was that you modified the LPG valve to get better performance for the flame, how is that possible?

You definately need to post a video of this A.S.A.P. I am now extremely interested in this. I want to 'see it in action'.

 

I got anxious and I scoured the internet for about an hour. Everything I type it comes back to the autoloc.com kit or the eatmyflames.com kit. I would much rather make my own so any info would be appreciated when you get around to it. No rush though I just got bored at work more than anything.

 

HMMM ! http://eatmyflames.com/what-are-exhaust-flames.php

I would have to say that these guys fall under the category DaveTinNY was talking about.
Same thing with the other guys Autoloc


There are many Flame kits on the market most are bad news for the engine using an ignition kill and firing unburned gas. The very few LPG systems that are out there do not tell you about the OPD on the new tanks. So you buy there plans build it and it does not work very well.

The system that I built is safe and will not harm the engine.
You have to first manually arm the system. There must be oil pressure(OP switch @ 15lb psi) and then to fire the plug there is a momentary switch the operate the LP gas solenoid and coil pack.

Bang110 in the picture it is only the Accel coil and what is attached to it that is the flame. Everything else is for other stuff. And yes I did it myself.

 

You do realize you're a freak of nature?!

 

YUP

My MINI is the sane toy. How about a past project. 59 MGA blown alcohol small block chevy, ford shortened rear end, Muncie 4 speed.....
Or my Big block chevy Cobra or my dual carb Monte carlo or my....
And to support the habit I had to open a Speed Shop.



Shop opened 1981 so I have been doing this for a while

 

Thanks for the clarifications, Nitro... I was thinking GASoline (should have read more carefully). As an ex firefighter, flames are somewhat of a concern when they exit a perfectly good vehicle. Can be ugly. In your case, however, it looks like you have the safety well thought out. :-) Flame on!
