ST help please
 

can anyone with a small turbo escort cosworth, pls tell me where their boost gauge sits on tick over? As I think I have a problem with mine, because when its on tick over its sitting at the very bottom of the gauge. :?:?:?:?

isn't going to?? you don't have any boost at tickover afaik..

Yeah I know,why would you want it showing boost on tickover LOL

Did I say it was showing boost on tick over:?:?
What I said was, the gauge is sitting on the bump stop at the very bottom, when the car is on tick over!

well you do have a vacuum at tickover I guess.. sombody else answer this haha

I'm sure mine does this but I can't tell for sure til tomorrow when I drive it, does it move once you pull away ? If it does I doubt you have a problem.

it does move when i drive,but it seems as if its trying
to pass the bump stop on the bottom of the gauge when
on tick over,i though that on tick over the gauge use to
sit about half way between bottom and zero on the gauge,
just looks as if the needle is going to bend,,:sad::sad:

Mine goes down to -0.6 bar but I can't remember if it goes to the bump stop on tickover.

ok mate thanks,
can anyone else help me clear this up:sad::sad:

does it sit at 0 when the engine is stopped? if it does, this is correct.

and it should pull down to nearly the bump stop (depending whether it has any air leaks or a aftermarket dump valve etc) when running at idle or on the overrun.

ok thanks mate
it does sit on 0 when the engine is off,and it sit's on the bump stop
when car is on tick over,it does not have any aftermarket dump valve
and i have just fitted a brand new t28 not a recon,the problem is it seems
to have developed a surge when driving and the needle seems to take
a lot longer to climb up the gauge.......

mine sit at zero when engine has stopped and -0.6 when im ticking over and raise when u boot it hope that helps

ok mate thats a great help..:grin::grin:.. looks like i do have a problem then
as mine is sitting on the bump stop when ticking over,though that it
looked like it was to low:sad::sad: now the fun of trying to find out why..

mine rests on the'' bump stop'' at tick over then climbs towards boost easily then on to boost then moves like a rev counter does(very freely) -you know you can drive around all day not using the boost!!!!!!!!if you wish-dont push the engine.
ive also got a dumper on mine at the fuel end as against the air intake end.
-no lag -just pulls+pulls+pulls (AS IT SHOULD)
