940 wentworth estate turbo

does anyone know what boost presure these things run at, and can they be tweeked without going to mad and to what boost presure.

Don't know myself but it might be worth posting at European forums like turbobricks.org and others, as they will know a bit more.

The car will certainly respond to standard tricks like tightening the wastegate actuator arm a couple of turns, or fitting a bleed valve, but it would be worth getting the experience of others on just how far you can take it.

Hi
Am I right in thinking that the 940 wentworth is 2.0 ltr with a low pressure turbo if so you may be able to fit the high pressure turbo from a 2.3 ltr only an idea

If you can get at the overboost cutout located under the dash , you can run whatever boost you want . Some guys in america are running 14 -16 psi on an otherwise stock engine , with a turbo and air fuel ratio meter to monitor if the engine is leaning out under boost . 12 psi would be achievable with a manual boost controller , std is 7.5 or 9 psi , double check if yours is low pressure turbo , the compression is higher to compensate , hence limiting the amount of boost . The keywords here are detonation , avoid at all costs , engine damage and destruction result . You should be safe at 12 psi although no guarantees could be given because i dont know how good your engine is !! . hang around on the turbobricks forum , you can pick up loads - exactly why i developed the boost controller - its the english version of a dawes device or grainger valve .

I was under the impression (but this is only very vague!) that the LPTs only differ from the HPTs by the ECU program, which limits the boost on LPTs?

I am quite likely wrong though - dont care cos the insurers say I cant drive dads 940 anyway....sulk....!
