Primary turbo not boosting?
 

Hi all,

Just got my car on the road after 10 months off the road.

Primary turbo isn't boosting and I have a seq setup. Any pointers where I can start looking to save me looking at every pipe and solenoid?

Cheers :)

Bad check valves are notorious for causing failure of primary boost. I would start by replacing them.

If you are getting full seconday boost, you don't have a boost leak.

Awesome!! Thanks for that.

Adam, I've already got the viton check valves and viton hose as well so I'm hoping someone just put the hoses in a bit wrong that are easy to get to :) If not I guess I'll run through the check list on that link.

It's also possible that the check valves were installed in the wrong direction. Good luck sorting it out.

**** is this true? i have been searching for boost leaks to solve my problem, but if this is true, i need to start looking somewhere else??? i get full 10psi at 4500 thru the rpms, it just seems a little slow to build boost in the lower rpms. im around 5-7 on the first turbo then shoots to 10psi at 4500.
