does the boost when boostin drop atall mine goes from 15 to ten then back up any ideas guys???

 

If your actuator is good it usually wont drop a whole lot, it will drop some however.

it will peak, tail off and as the revs rise it may pick up slightly more.


HTH

 

^^^^As above


This may seem a litlle obscure:

How accurate is your boost guage? Can you feel a noticable difference as the boost drops off?

Ive seen a lot of boost guages sugest that (X)psi is being run however when tested the sugested readings are way out!

 

dodgy amal valve if u run one

 

what is the amal valve mate said to have a look at thats sorri guys my first turbo so im learnin cheers for ya help by the way

my engines modifeid to around 180-195 bhp runin asfar as i knoe 15-16-psi should i adjust this down up etc???

theres a reall flat spot when im in boost hit the rev renge drops then doesnt seem to pull back quick atall ???

also the boost gauge flicks up and down quickly

 

The boost guage will flick up and down quickly when you change gear or lift off the throtle as it switches from boost (on throttle) to vacume (of throttle)

DO NOT adjust the boost yourself, it WILL end in tears

The amal valve is a form of boost control, im sure it basically brings the boostin softer rathern than without where the boost would come in hard and make the car less driveable.
