Right, if I weld the flap shut on a t2 for the wastegate arm and left the wastegate arm off the turbo and plumbed in a mbc could I control the boost with the mbc or am I missing something
Mbc by itself will control boost. If you weld anything you take away ability to adjust it.
Yess Danny you are missing something. When the MBC opens at a set pressure it opens the boost can which opens the wastegate, If this is welded closed then it wont open rendering the MBC useless...
Had a think about it this morning when I'd sobered up and realised that wouldn't work
Welded shut and control with fuel seems to be the way I'm going then
If the wastegate is just disconnected, what will a T2 push up to ?
On a 9mm with max fuel screw adjust just lower than 2K revving and LDA rotate.
30+ psi
Would be well out its efficency range though.
Did you get any pics of turbo?
