From Audi 100 to urS4 in a week

[UrS4boy]

ahh, fair enough. Was trying to find something stock-ish looking

VDO was a good choice for that (stock looking). It's just that there are better VDO boost gauges.

VDO has a number listed under "Turbo" (not "boost") including the one below (good for Stage 1+ (e.g. 24 psig)) but not RS2'd Stage 3 (26 to 28 psig):

that's why there was only couple coming up, as they called them turbo gauge Thanks

[UrS4boy]

Great information as usual, thanks. Will make one good instrument cluster from 2 I've got, and experiment with the bad one.

Here's one done by a well known UrS person ("Igor K.") with mad engineering skilz of all sorts. Unfortunately, he says he did this 15 years ago on an 1997 UrS6 (must have started with an UrS4 cluster) and did NOT document what or how he did it. He said substituting the Voltmeter for the clock was quite easy.

Sure.

Thanks

So just went on a motorway and it won't go past 4k rpm in 5th/6th gear, and there is no shaking or anything, just won't move further. 1st, 2nd, 3rd gear pulls like a train, boosts nicely too.

With stock tyres (225/50/16) and a 0.73 top gear, 4000 RPM = 98.5 mph (158.7 kph).

Maybe you have a speed "nanny" in the software.

Assuming that your fourth gear is 1.03:1, what happens when you take it to say 6000 RPM in 4th? - should be 105 mph (169 kph)

What happens when you pull up the anchor and retract the drag chute?

I am starting to think I have a "nanny".

I don't think I've ever gotten past 100mph, 4th gear will go past 4k easily.

I will try on Sunday (will be on my own in a car)

What did you mean by this: What happens when you pull up the anchor and retract the drag chute?

Catalysts?

[hunker7]

Opened up and cats are not blocked. That was my first thought.

Unplug the VSS vehicle speed sensor, right by the clutch slave cylinder. Car (or nanny) won't know how fast you are going.

Ask the police car following you.

You're not helping mate

Just try and get over 4000 rpm in 5th...

Something is physically holding you back. Creating more drag/friction than normal.
