my car has a flat spot when you come on boost the car sort of holds back and won't accelerate. it clears up at after the about 10sec's and goes like stink.
it gets worse in higher gears
it holds boost fine.i must find the fault soon cos i'm going crazy
i had put the car in for a tune up and got told they have taken ma dump vavle off and it seems a little better but still the same


do use think it is the turbo thats gone or any ideas folks would be great

 

did you have a tune up or a proper set up on the rollers?

 

a set-up on the rollers ther have been working on it for 2 hours

 

a good tuner will find the problem dude

 

but i think the guy who was working on it is a cowboy and will rip u off mate thats why im trying2 see what others think

 

who was it? why waste money if you think theyre cowboys...

why would it be the turbo?

take it to someone good

 

falkland performance

i have been told there is a crack in the turbo

 

get it to AVA. . dont waste time or Ł anywhere else.

could be a boost hose collapsing under load.

are they std or samco?

 

its got a samco boost hose on it and i was told i cant run a dump valve on ma car for some reason but not told why

 

*Runs for cover before the dump valve ruck starts again*

The main reason, aside from hating the sound, is that the engine hates air leaks, which is exactly what a dump valve introduces, and the pressure isnt enough to need one, as it wont damage the turbo.

 

but surely it would be the dump valve making the car do what its doing when it comes on 2 boost

 

is your cam worn?

 

everything in the engine is all new just been in it for 2months

 

hi mate... i get the same problem with mine. it really pisses me off. have u found out wot it is yet???<escort cab... efi frst engine>
