no boost
Turbo Mini Forums

just another cry for help
took the car up the road petrol starvation now sorted, but when car is reved do not seem to get a rush like u would normally get with a turbo it drives like a normal na car is this normal or a i missing somthink, not running big bhp only standard, is it because i'm using a na engine with turbo told cam might effect it, inlet maniford blowing slightly (will do this the weekend) will this also affect it , thanks in advance

Have you checked for anyother leaks? is the watsegate stuch open? Is the turbo free and spin up? (check on idle with an inspection mirror) Is the engine an MG unit or not, if its an MG unit the cam shouldnt be an issue? Do you have a dump valve, is the diapram ok, and sealing? is the actuator set with enough preload, it may not have and the wastegate is opening at a low boost level so your not noticing the pull that you would if it was set eg to 7psi?
Just a list for you to check to get you started.

Could be any of the above.

Mine did the same when my preload was incorrect, the wastegate opened on the first sign of boost.

Inlet manifold leaking will be drawing in air making it run lean off boost.

1/4mile in 13.2sec @ 111 terminal on 15psi

defo not the cam...Metro turbo used a bog standard metro cam anyway.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

hi shane
have checked the actuater it has enough pre load half a hole on rod checked by bud666, turbo does spin have checked with mirror, dont know about the engine and no i dont have a dump valve will do gasket first befour anythink else thanks lads

Hmmmm curious...... Can you check the over boost cup and spring in the plenum, may be week, and not sealing?
Shane

OT: How did you sort the fueling issue?

needed the extra holes in the plenum>carb gasket :)

shane
do not have the spring in the plenum told by bud666 mate who i brought the plenum pipe off to seal it with 5 pence pieces so i asume to be right, did not question as he knows what is what, still hoping it's the leaking manifold still not had chance to change the gasket yet had to work all weekend but first chance i get i wll sort it, thanks for your help

5p's will do the trick, mines been full of em for years now, hehe.

Hmmm, Im running out of things to suggest? Have you tried a compession test to rule out head gasket, valve seating issues, also warn rings?
