Also Chip / Danny / other turbo heads, do you think ill be pushing my luck on a T28 at 1 - 1.1bar on a 270 degree bearing, worth having it rebuilt with a 360 bearing for reliability?
It doesnt work, i wound it fully negative (exactly as the turbosmart insturctions state) and did the 15+ Psi, to check i wasnt being stupid, i wound it the other way completely and it was exactly the same, and the vac lines were on the right way round.
I think the actuator is getting a touch lazy its not hitting boost as hard as it used to, fitted a Turbosmart manual boost controller to try and trim it back to 10psi. Took it out for a drive and gingerly hit the throttle and it shot up to 15psi with little effort with the engine/turbo makeing...
Um i used some M10 studding from screwfix and hacksawed to length, nothing fancy im afraid!!
Replaced the air filter today, after i originally ripped the neck off the Jetex filter and glued a neck on, that has now failed and a jubilee clip rubbed through makeing a small hole.... its now seen...
I've got a Ph1 head in the shed, the inlets do look a bit different IMO, they are a bit neater and better machined (by eye). Ill be using the ph1 head on my high boost build for the larger exhaust ports though :)
