Plumbing wastegate on split inlet housing.. Ideas?

Hey guys.. Since going with the Master Power GT45 turbo, the exhaust housing is a split inlet so I have decided to keep the left and right bank seperated going into the turbine housing..

My question.. I am running a single 50mm Wastegate, and would like some ideas on plumbing it in to the exhaust.. I am very space limited and the gate is rather large.. does anyone have any pictures they would be willing to share on their setup? I am thinking of having two 1.5" tubes coming off each exhaust side and Y'ing into one 2" tube going into the wastegate. I want to keep these tubes as short as possible as not to affect the dynamics of the wastegate's operation, but due to space limitation, they may need to be longer then preffered. any help is greatly appreciated!

Let me make sure I understand. You've got a twin-scroll turbo and you're wanting to run a pipe into each half of the housing? If so, that's not what it was designed for.

The only way to truly keep the banks separated is to run two wastegates.

As soon as the gate cracks open, pressure will equalize in the system. (if only running one)

Chris,

Mind explaining the twin scroll? I was told if I did not keep the inlet seperated it would cause the turbine housing to glow due to heat buildup. and I was also told spool would be quicker if i kept the exhaust pulses seperated going into the turbo. please expalin, this is the help I need.

Intmd8,

Yeah I am wanting to stick with one gate for now.. I don't mind the pressure balancing out in the exhaust, i still think the pulses will stay gathered better then if i had put a large single pipe going into the turbo. anyways, if you think i can get away with running one large pie without making a difference or addign heat to the setup, that is the way I originally had planned to do it and would be MUCH easier.. I just wanna do this right the first time and not have to redesign it down the road too many times.

any help appreciated
