The question that i have is if we place the flex joint/bellow lower down on the downpipe it would it still allow the same amount of flex protection that it would if it was closer to the actual turbine housing? For example, if the downpipe is a solid tubing and we place a test pipe with a flex bellow attached would that provide the same amount of flex protection? don't ask me why, but the person i'm making this for doesn't want to cut up his aftermarket downpipe to weld-on a flex bellow.

Thanks

 

Onthe downpipe, after the flange, all are good. As long as it is fairly close to the engine.

Hell if you really wanted to you could build a manifold with a flex section on each runner.... Then just brace the turbo.

Technically, you could, but i don't think they'd hold up to the heat very well.

 

you can get them made from some of the more "exotic" materials.

and the flex will work on the test pipe...if you want more freedom, grab a longer flex section.

 

What's goin on with the center section of that turbo?

 

some sort of electronic VGT controller thing, could be electrical turbo compounding, i dunno...that pic is from the banks power site

Its probably some sort of variable tubine setup.

Maybe I'm missing something. Why would anyone ever want to do that?

Maybe thermal expansion? I really dont know...

I'm still trying to imagine over 200 mph in a diesel pickup truck.

Yeah, stainless expands alot under heat.

 

Actually the VGT (variable geometry turbo) Takes place of the wastegate Normally it's PW acutated using the oil send line to the turbo through the PWM circuit which is controlled by the managment system. Used in diesels often.
