spooling but no boost..please help
i just finished installing a custom turbo and was driving around...i can hear the tur bo spooling and bov is going off...but im not getting any boost...im thinking its the actuator because its not opening/closing the flap to the wastegate....but when i blow into the tube to the actuator it moves the flap...i also checked the nipple from the comprressor to seee if there's pressure coming out...the pressure didnt seem too strong to move the actuator...pleae help..

Re:spooling but no boost..please help
uhmmm boosting really low?
a leak somewhere? ??? |
Re:spooling but no boost..please help
if the bov is going off then you have boost...i bet your gauge line is pinched
|
Re:spooling but no boost..please help
its a t3...the thing is when im driiving and looking at the actuator..its not opening or closing the flap...is it supposed to?
|
Re:spooling but no boost..please help
how can you drive and look at the wastegate actuator? ???
the wastegate actuator works off of boost, not vacuum. |
Re:spooling but no boost..please help
i drove it on a lift...but i guess its not as acurate than driving on the road...but on the road...the boost still only goes to zero

Re:spooling but no boost..please help
On a lift will not give you any boost.. The engine has to have a load on it, otherwise it will not make power.
If you are still getting 0psi on the road, Start checking for leaks in your charge piping, it doesnt take much. If you are absoultly positive you have no leaks whatsoever in your charge piping do this..... (be extremely careful) take the vacuum line off the wastegate actuator, and just go drive it real quick, but keep an eye on the boost gauge, dont get all ------- throttle happy, because with the wastegate line unplugged, it will spool 20+psi. this is just to see if everything is working ok.. spool up to 5-8psi just to make sure its working. You may have a defective wastegate actuator. But more than likly you have a leak. Keep checking, and let us know. Jeff |

So the actuator moves when you blow into it? That must be a considerable amount of pressure your putting through that tube. I wish my girlfriend could do that. ;D
