I'm about 3 weeks from joining you i think ..... there's a distant calling, i can hear it now .. it wants me to put a 3" pipe all the way from the downpipe to the back 
jesus devon i thought my car kicked out some black smoke was that with propane?? as i was kind of hoping when i get the propane kit it will help loose some of the black smoke. i just went for a miltek because it looks nice, i do like that whistleing noise but i'm sure after w eek it would drive me insane. devon do you have a thread with a list of all your mods i'm currently trying to get my car as fast as possible lol need some inspiration although devonmikeyboy has been a great help in that department
I don't have a list of mods, but check out Allards stage 4 tuning on their website. I have it all except the injectors, but I do have propane and NOS.
That black smoke was simply due to them loading the car at 1500rpm. You have to see how it clears up on boost - This is how it is when I drive it - I never load it up so low down on the revs. I have a rule I'll only use WOT in 4th/5th/6th from 2500rpm and above.
The car WILL be 100% clean eventually, but there's not much you can do when a dyno is loaded up at 1500rpm - you have to use WOT from 1500rpm to get the true picture. This is why the power only really comes in after 2000rpm - there's no boost any lower.
Unclefester. 3" is not necessary. Just putting in 2.5" is more than sufficient for a straight through pipe. A wider pipe might be better if retaining the cat or any silencers, but with a straight pipe the system is so efficient, there's no need for a huge bore. My downpipe is a "big-bore" 2.5" one (with no bend compressions) and the "pipe" is just 2.25", yet I'm pushing for big power. I bet if I'd left a backbox in or something, I could have done with better. A side benefit of it being so efficient is nice low EGTs. I've not seen over 700 degC yet, and that was a 5th gear 80-120mph slog up a half mile long "autobahn" - gaining around 150 metres in height too. (one of those hills where lorries end up doing 5mph in 1st )

It's very sad that most people just can't understand this simple fact...
You want to see a real smoking diesel (remaped BMW 330cd) on the rr? Take a look at this: http://www.youtube.com/watch?v=1mVTPEw6c7U
I'm almost proud of my rolling road vid (though it's tricky to see the smoke out of the sunlight):
Gotta say there is pure diesel running through my veins... I love the idle noise, smoke, etc... I had a lickle 'race' with a Corvette Chevrolet (425BHP as standard) and went past him at around 120MPH. It turned out we live in the same area and got off the motorway at the same time... A few junctions on, he pulled up alongside, wound down his window, I said hello, etc... and he just said, 'What the hell is that!?'. He couldn't quite believe it when I told him it was a diesel golf!
Exxxxcellent!

Heh yes, think you need a better way to record video though ... the sound is not too clear
Well not that much to hear anyway....the rollers noise is just hugely loud and at the time I still had the standard exhaust fitted... Next time I put it on the rollers tough I'll try to record the nice growl wot sound I now get.
That BMW smoked right through the rev range, which mine doesn't. Just shows the difference a good map can make, even if mine is somewhat dodgy low down. I'm never going there on the road, so it doesn't bother me. I wouldn't mind a bit more at the top end though - would mean the turbo could be given some more work to do.
I wouldn't say the difference is between a good map or a less good one...it's far from being that simple. It was a question of power and figures you wanna achieve...
For instance that bimmer at circa 270bhp smokes just a little bit....but at "full-power" stage - like the one that was filmed and recorded 290bhp on the rollers smokes like a freight-train... But it certainly did go fast on the road (very even with a E36 M3)! The hardware (turbo, etc) was ALL stock.
Yeah well maybe they should have tuned the car properly and fitted a bigger turbo etc if they want the car to run that sort of power. Maybe then it wouldn`t be so embarrassing to watch.
Yep, that would be deffo my choice, but there are some people out there that seem to actually enjoy "smoking" other cars...

Time and a place of course, and they usually bring it upon themselves as well. Similar threads
