Stock Boost Pressure - GTI

[yokom46]

Afternoon Gents,

I'm like the next guy and love my spec's. Does anyone know what the standard boost pressure is for the 1.4tsi Polo?
I've done heaps of googling and can't find an answer.

Polo GTI reviews don't seem to mention it, but you'll see it in some Skoda Fabia RS ones (which has the same engine and dsg).

It does, however, come with the same twincharged (super and turbocharged) direct-injection 1.4-litre petrol four, which features relatively high 10.0:1 compression and boost pressure of 2.5 bar to deliver the same 132kW and 250Nm between 2000-4500rpm.

You're amazing, thanks man!

Didn't realise they shared the same power plant otherwise it mightn't have been that hard to fine.

2.5 bar, F### me. Thats near enough 40psi !

[Polo_GTI]

2.5 bar boost pressure? Really?

[richycreations]

2.5 bar on 10:1 sounds ridiculous, this has to be incorrect. If I were to take a guess I'd say around 1.2 bar.

same question, but for the polo 77 tsi ?

[alexaescht]

What about the 66 TDI hahahaha

[nomadx38]

The 77TSI runs boost at 1.5Bar (22PSI). There is a page on Wikipedia that shows all these specs on the various vw engines.

supercharger provides a boost pressure of 1.2 bars (17.4 psi). Could not find turbo but wouldn't be far off.
Not to bad considering my liberty GT-B STI 2.5L peaked at 15 ish when you punched it then dropped promptly to a steady 10.

[nomadx38]

The boost for the turbo is listed just below the supercharger details. The KKK turbocharger boost pressure is 36.3psi (2.5bar)
