Competition Twins Almost Done, Questions

[Partyat33]

My twins are almost done being fabricated. Now the details come in.



On the supply line to the stock turbo the fitting appears to have a restricting orifice that is much smaller than the line feeding it. The hose I had made to supply the BHT3B does not have such a restriction. Do I need to restict it so that it will not overrun the drain ?



If I want about 50#'s of boost, what opening pressure do I set the external waste gate at. Right now I am planning to set it very low and increase it as I get data back from testing.



Thanks

I would think not. My drain line is 3/4" in diameter. The supply line is a -6. I would think the 3/4" drain is more then enough for flow.



As for the waste gate... I am not running an external.

Don't sweat the supply or drain it's fine and start low on the wastegate and go up from there!

Thanks for the input. I won't worry about the supply and drain then. I am planning to leave the 'boost elbow fitting' off the 35 and run the through fitting. I know that wastegate is pretty small, it will be interesting to see how much if any it interacts with the external wastegate.



Thanks again.
