Anybody had pyrotechnics like this before

[diabloam]

only this trip home I have been using my turbo regularily and with it running great now and with new suspension and brakes its a joy to drive with great pull and no clonks or anything, people cant believe that it is 26 or so years old.

However, gave it a trash on a quiet open stretch of road (private, lol) in the dark last night, held it in fifth from 60 up to 145, full boost for ages. Happened to look in the rear view mirror to see small glowing embers coming out the tailpipe.

The car was overfueling badly for ages before I got bits to sort it, so could this just be crap from in the exhaust burning up and exiting the tailpipe, heard of this on cars that never get thrashed, does my diagnosis hold firm, what does everybody think, car remains running great so it cant be anything serious. Could my exhaust be partially blocked or anything and this was some crap getting blasted out?

It could well be little bits of carbon, deposited when the car was running over-rich, heating up and flaking off now the thing is running right. Probably from further up the system rather than the tailpipe itself, I would reckon.

Exactly what I was going to say well except to add I used to love the 4th to 5th change at just below 140 myself

Could also be bits of exhaust baffle being blown out.

I had this coming back from a TIPEC meeting in my S2, after a sizeable high speed blat along the motor way, came down the slip road and looked in the mirror to see showers of sparks. I thought the car was on fire! Nothing to worry about, just the exhaust getting hot and burning off the carbon. The trains I am on do that as well when put on a hevy load for thr first time in a while. Can be quite entertaining watching it light up the sky.

Good description. Sometimes known as an 'Italian Tune-Up'.

The car should run better as a direct result.
