The tubing for my boost gauge has come disconnected at the turbo end, so obviously the gauge no longer works. I had the gauge fitted (part of a three-gauge Racymex set) when I bought the car.

My boost gauge has always only ever shown positive readings (ie, no negative boost). I seem to remember someone saying that there are two possible connection points that can be used, and that Gertjan (the dealer in Holland) tended to use the one that gave positive readings only, because this gave either a more accurate reading, or a steadier one. Can anyone comment on that? And can anyone tell me where this other connection point might be?

Thanks,

Pete

I'm not sure but there is a boost gauge tapping point just behind the alternator
or take a lokk at chairk's scooby gauges site it will show you were I mean

Hi Pete,

Should be 3 rubber pipes side by side on the top of the engine in the middle. think any of these will do. I used the farthest left. gives -ve readings too.

Cheers

You could always take it off the manifold, which absolutely gives manifold pressure
