VDO gauges?
Hello all,
Which boost and oil pressure gauge would be more appropriate for the 1.8T?
1) 15 or 30 psi boost gauge?
2) 80, 100 or 150 psi oil pressure gauge?
And would you go with a mechanical unit or electrical?
Thanks,<p>Nick

I did both of these.
I installed VDO's turbo gauge that measure from 30 psi of boost to 30 inhg of vacuum. With an APR chip, I see a range of 18 psi to 28 inhg. I think the gauge is perfect.
I also installed an electrical 80 psi oil pressure gauge. Installation was a pain as I had to T the new sender with the old to get the normal warning light and tone to work right. My whole painful experience is in the archives.
I see 80 psi when the engine is cold and when running over 2500 rpm or so. If I were to do it over, and I may, I'd use a mechanical 100 psi gauge.
Good luck,

K03, usually makes 15 but ...
In the Texas summer I've seen pressures up to 18 psi. I talked to APR about this at the time and there have been discussions here too. The older 1.8T engine regulates air flow not boost. This results in higher pressures when it's really hot.

Re: I did both of these.
If I upgrade to a K04 turbo later on do you think it might generate a psi rating above 15?
Therefore install a 30 psi unit!
Thanks for the info,<p>Nick

I think it can.
I haven't driven in a K04 equipped car, but folks on the forum report boost to like 20 psi! I think it depends on the chip programer. I think the Garrett chip makes more than 15 psi with a K03.
My problem with my oil pressure gauge is that it reads 80 psi at times, which is the last mark on the gauge. I don't know if it's actually 80 psi or if the gauge just stopped there. I recommend getting a gauge that goes higher than the largest reading you expect.
If you do a mechanical oil gauge, I'd love to hear how it works out. Keep in mind you'll need a t-pipe. VDO makes one.

Decided on the 30 psi boost gauge!
Talked it over with a few others and I will go with the 30 psi unit.
As for the oil pressure gauge leaning towards the 150 psi model, will not be installing the mechanical one though. As you probably know it's a lot of work for the little extra accuracy you get out of it!
Thanks for the help,<p>Nick
