Smokey pug & "clean tune" power?

[nick000]

replaced the standard silencer with a nice piece of Stainless tube on my xtdt today (update to proj thread to follow) and was amazed at the amount of smoke on and off boost.

I presume it's just now more visable due to exhaust tip no longer pointing down but it was so bad I have cut back the fuel.

This had led me to wonder what sort of power is possible whilst maintaining a minimal smoke "clean tune" ?

Theories on new found smoke and rr results with a clean tune much appreciated.....

Could prob push 115/120 on a virtually smokeless tune id imagine. Take some setting up mind

Just drive it properly.

Sounds harsh, but its true.

The difference will be the standard silencer...its quite tricky to setup a bosch tuned XUD I have found with standard silencer coz it just clogs up with smoke rather than releases it...which the stainless tube will do.

Presume you mean feeding the fuel in and not just stamping on the throttle?

Yes. give it the fuel to get the turbo spooling just enough and keep going down and down as you feel it pulling. Makes it a lot quicker than matting your foot coaling the f*ck out of life then the turbo finally spooling and yer off!

for sure - that's how I try to drive it, just amazed at how much more smoke than with stnd box. Despite cutting fuel back it doesn't feel down on power much either....

Maybe you need a bigger turbo

Where do you live?

I ran over 180hp, with it pretty much smoke free, see vid:

how can you call that a tune... you can still see the back of your car =D

[jammapic]

It made 209.9hp with it "tuned".

[nick000]

Gave it a "good run" on the way to work this morning and the performance improvement even with less max fuel is quite impressive. Going to set fuel back to give 19 psi boost again but be even more careful to "feed the fuel".

Pulls better through rev range now and no gov mod yet.

JP- impressive "clean" 180hp tune

Anton - just up the road in Witney

Welcome to have a look and play if you want

Thanks Anton, may take you up on that at some point. Lots of mods to do yet though before a "final" tune
