got my cossy running in my mk 2 escort, but on the boost gauge im only getting 0.2 bar boost.

Is it a question of adjust the actuator or amal valve problem?

pressure test the inlet system first my guess is there is a boost leak somewhere, check all the connections specially the throttle body one it's easy to fit it with the bottom section not over the throttle body correctly

when you tap the throttle can you hear the amal valve clicking?

if it stays permanently off, you will only have that much boost, i.e. if the ecu thinks something is wrong

Amal valve 29 ohms across the terminals
Turbo was working fine on the car i got it off

Am I being daft here but are you trying to get boost with it stationary?

the back end is up in the air! so it is driving but going nowhere!

There's no load on the engine though.

Can it be driven? If so.. drive it and see what you get.

I don't think you'll get boost with it driving in mid-air.

Have you tried to actually drive it and see?

the problem is its a track car, stickered up with no tax or mot!!!
When i did drive it - no boost!
would you still get boost with it free wheeling in the air?

GVK.

I don't think you can get boost without load on the engine (ie stationary or in mid air) happy to be proven wrong though.

try it with the handbrake on lol (dont!)

PMSL, I nearly burnt the clutch out on a Passat on a 4 post ramp doing that trying to find a boost leak
