Dual Wastegate set-up?

[4g63telantra]

Ill be running a GT40 with divided turbine housing and I had a custom made manifold made for a 38mm wastegate. I still have time to add a another 38mm flange for another wastegate.

If so would it be safe to run 2x 38mm wastegates? and if so what springs would I have to run on each?

Same on both wastegates? (ex 15psi = 7.5psi spring on each wastegate? or 2x15psi spring?)

Also how would I run the vacuum hose to a electronic boost controller?
thanks

You still have to run 15psi springs otherwise they will openup too soon. SLS makes a dual wastegate manifold already and I have seen it used a couple times. As far as the elec. boost controller, you would want to get a V style T to get them into one vacuum line.

You can always just use a block off plate on the 2nd wastegate flange if you decided to only use one. I would put 2 on.
