I've heard about it before, but never actually seen it happen.

I did some work to my Jetta over the past few days... upped the boost & fuelling, took out the cat and a proper "mufflerectomy". Last night I decided to take it out at about 10 PM to "shake it out".

Merged onto the highway @ 4500 rpms, EGT ~1200. Car sounded great and was pulling nicely, although only had 8 lbs boost.

Looked in the rearview mirror and saw red embers scattering behind me... I let off and they diminished a bit, but I was still getting some. Highway was clear, so I decided to put my boot in it again.

Saw 1200* in fifth, and then it really left a trail for about half a kilometer, then the embers tapered off. I must have had a lot of soot in the exhaust.

Weird. I've never heard of that before. I'd love to see a video of that!!

we had a race to the fuel station one night at work. a ford cube van and one ton chev van, both diesel. I was driving the ford cube, and as I passed the stuggling junk chev, showers of sparks were reported shooting out my tailpipe. Probably normal, though I remember witnessing a real lightshow out the tailpipe of an old A1 jetta n/a that was refusing to blow up. (19mins full throttle, no oil or coolant. Just kinda slowed down and stopped. Started again 1/2 hr later and drove it 10 mins to the wreckers. left it at full throttle in the parking lot and went home!)

I think it would have scared teh hell outta me, but I've read about it here before So I knew what was happening.

Quite a difference without the backpressureof a plugged cat!

Not overjoyed with the response from my T3, the bleed valve made a bit of a difference but a ball & spring type controller would probably help a lot.

I'm nervous about adding too much boost... the car is my daily driver, and it has ~350k on it (kms). I'm thinking 10-12 PSI? That sound about right?

That would have been something to see.

My neighbour was concerned the other day when he was following me and I was getting a bit of black smoke when I pulled away or shifted gears. He would have died seeing embers coming out the pipe.

I have first hand experience of ***ting myself to!
When I ran my M-TDi in my T3, I came back from York to Huddersfield on the M62 at more or less full chat, glanced in the mirror to see red embers, didn't think anything of it, just thought someone had dashed a tab outta the window, oh no, looked a few seconds later and there was a proper shower of red embers scattered accross the motorway! *** my pants! :lol:
Backed off a bit and it eventually calmed down, booted it again and back came the embers! scarey stuff!
To be fair the van had been trundleded about for a while, so a good long twatting down the motorway did it some good!

at my old standby generator job
we had 50,and 100kw rental generators powered by john deeres
well we had one customer that always needed 50hz electricity,for overseas stuff
they would have some big old 50 kw generator sitting there,and a line cord runnin inside so the guy could test drills
lol,just a little overkill
well we would get these gens back,and they would be all wet+gooey in the exhaust from never getting warmed up(wet stacking)
so we would put a resistive load bank(basically a huge toaster element) on them,and watch them shoot flames out for 3 feet high,,and the cinders??ouch,they'd burn when they landed on ya :shock:

LeeG · « **Reply #11 on:** October 17, 2006, 10:42:12 pm »

Yeah, I posted on here about my car doing this early one morning. Accompanied by a truly massive smoke bank, as witnessed in the lights of a car going t'other way. And yes, I had been truly flogging the poor beasty before this happened.

If I could make it smoke like that a will....imagine what would happen to the next nose waver driving a 5000lb SUV that doesnt like the way my car smells :twisted:
