Golf R Observations and Questions

[entice]

mine does it too.. and it's standard.

Maybe PCV blowby?

Do the turbo's "coke up"?

Seems they store soot when cruising then dump a heap of soot under load.

If it's just the engine running rich under load, I'm happy. Rather that vs a lean AFR mix.

This! All the Japanese cars run super-rich under WOT, but it's less common in the Euros, and rarer still when tuned. Still, short of being a bit down on peak power, there's nothing wrong with running a bit rich. The excess fuel lowers the combustion temps inside the cylinders.

My tune is running a slight bit richer than is optimal for peak performance.

But I don't mind that. I'm sometimes in area where I can't guarantee good fuel and would prefer to be a few kw down on power for that sake than anything else.

Most tuned R's and indeed stock ones do give a little belch of smoke.

A bit of the smoke under WOT is also from carbon build up which the Ea113's are famous for.

Got to get that catch can fitted.

True that.

My observation is after being away from the car for a month, and giving it a good bootfull in this cool air, the boost it produces forces off the boost gauge cable from the 42DD tap..... oops! So I popped it back on, and it popped back off again next WOT. Turns out the hose has a ring of oil on it, which has softened it up compared to when I first fitted it, and the oil has somehow accumulated after a month of not driving it. So catch can is definitely going to go in soon (and a cable tie seems to be doing the trick on the hose).

Adzy your a madddd k@#t!!!!

My GTI used to blow a bit of smoke under hard acceleration - had to get the PCV replaced (under warranty)

My R, never in 20,000 km so far under any conditions.

AFRs on rich side too
