I've checked the lines several times as well as the controller (with compressed air) and everything looks fine. Even switched the lines around, but it made no difference. These are Tial 44mm units.

Just throwina few things out here.

Pull off all the lines to the wastegate, and boost it. Just make sure you watch the gauge or better yet have a passenger watch it while you drive. You can easily over boost if you not careful so if it exceeds 10 lbs you have your problem and can fix it.

If you are still not seeing more than 10lbs then, you might want check the spring rate. What bar did it say on the box.

What brand of MBC are ou using? If it's just a simple check vavle, it could have something in it, have a bad seal, or just plain be defective, even if it worked fine before.

Don't remember the brand of the manual controller, it was what Mark used when he originally built the car. I just regulated air pressure down to 16 psi or so and then ran it through it's paces to see if it changes psi as it adjusted, which it does.

I'am not a motor guy but my neighbor is Tom Nelson. Give him a call. He's a cool dood to deal with. I bet he has an answer for you. That way we can get a video out of you sooner. By the way your attention to detail and assembly is awesome. Giter done!!!!

Tom could help me, but I hate bugging him as it isn't his motor and he's a busy guy. It is his headers though..................... :D

Made some progress.

In this buisness bugging is like a middle name it will never leave. Tom's to much of a nice guy not to help. Besides when your invloved on a car of this calibuer and your parts are on it you could bug me all day if you had to. I personaly don't think it will bug Tom. I work with him all the time. Now give him a call and get this issue resolved!!!!! I want to see this car on video?:D

I've experienced that a MBC can mess up, I do not know all the different models, but TurboXS has one which I know, and it utilize a spring with a ball (a ball bearing type ball). Sometimes it happens that the ball gets stuck. And you will have to dismount it, and put it back together...

Also remember that, when using a MBC, you will open the wastegate(s) even if the wastegate-spring is set to more psi than the current boost when the MBC opens.

So... If the MBC is messed up, it will help the wastegate(s) to open earlier than the spring is set to...

If you bypass the MBC you should get the pressure that the wastegate(s) are set to (if you have traction).... I would try it in high gear and see how the pressure builds up...

Sincerely,
Morten

Hang in there buddy!! It looks killer BTW!!! :cheers:

So..........

well, there's a bit more drama going on, not related to the turbo oil drain. I'll re-post when I get it done and on the dyno along with some video.
