Boost Gauge and BOV

[PoloPie]

That is a lot of boost for such a small turbo/engine...

This might be slightly offtopic since you're taking about the TSI, but I'm curious about the maximum boost pressure in the 66TDI but I've had no luck finding it anywhere. Wiki doesn't have it and I've read the polo brochure over many times, does anyone happen to know? I've bought myself a mechanical boost gauge and all the required fittings for a tdi but as it turns out, to get the intercooler-intake pipe out to tap into you'd likely have to take off the front of the car. There's one sneaky little bolt that's incredibly hard to get to.

More effort than it's worth just for curiosity's sake at the moment, maybe at least until the warranty has expired and tinkering can begin

Thin mr reliable wikipedia might have accidently put in a 1......

I can't find anything supporting that. I did see something saying the super and turbo combined had the capability of 2.5 bar, but that was about capacity more than how it's been set up.

Makes sense the 1.4 would have a lot of boost, I'm just after some actual data...

The tuners should have some if they are willing to assist...

36.3 psi... Produced by both turbo and supercharger. That's why the low end torque is so nice...

No info on the turbo alone...

That 36.3psi appears to include the 14.7psi of ambient air at sea level.

So really, more like the 21.6psi peak, which is spot on what some other sources are quoting (most saying 22psi)

Edit: Regardless, you can't really compare pressure between different turbos because you need to factor in the compressor map and flow.

Think of it this way, blowing high pressure through a drinking straw doesn't really move much air out of the end of it.... a light breeze flowing through drain pipe is moving significantly more air with much less pressure. Flow is king, not pressure alone.

True about the flow. That's why people get a K04, better flow than the K03. Not as much change over the K03s.

Still dreaming of a hybrid, but by the time you get the FPR, injectors, better fuel pump, exhaust, etc... It adds up.
I would like the 220kw atf tho...

Yeah i am starting to dream of a Motec, built bottom end and heads and an BW EFR 6258 with billet compressor wheel, integrated wastegate, bov, etc rated at 375hp~

Geezus, that would cost a mint... Wasted in a fwd.

Damn, that's one hell of a blow job!
