boost gauges and calibration

Since we're talking about turbo boost gauges, etc. and what happens when the vacuum hose is not doing it's job, are the stock gauges that Saab puts into the instrument clusters actually calibrated in a way that makes sense?

it's fine to say 'dont take it into the red' but that means nothing to most people. 8-) When I've had the engine running in the 1983 8V turbo car I'm repairing, it's a bit confusing with the way the needle changes position depending on how much throttle the engine is given, etc. Once I get it roadworthy again (still needs tie-rod ends, ball joints and inner CV boots to be replaced first), I'll take it for a proper drive on the local road at a quiet time of the day to figure out what the turbo does (or doesn't do).

I guess it's one reason people fit boost gauges with properly calibrated scales.

Enlightment on the use of English is certainly needed by some posters.

OK, I understand, thanks Fred. Now my Aero is no Ricer. Actually because of the "new car" snobbery that's prevalent in the UK it could almost be described as a sleeper, though the JT61 exhaust does tend to announce my presence and intentions :-)

My point was that most C900 enthusiasts who fit them do it to allow them to set base boost, and monitor more accurately their turbo performance, which can drop/rise significantly under certain circumstances.

You want a Ricer type mod, look here

I might just go back to a recirc valve if the local chavs 1.2 Puntos are going to start going whoosh...

Sleeper? Mine is usually referred to as "a shed" :) Personally, I abhor new cars. I just don't get it.

A car just has no personality until it's paid for, the warranty is expired, and it's all nicely broken in. There's nothing to really tinker with on a new car.
