Super Phatshaft 64/71 Wastegate Adjustment

[WideHips24V]

I am planning on running a Super Phatshaft 64/71 over an S480. I know you can adjust the set screw inside the 90 degree elbow but I am currently running the Super Phatshaft on my truck as a single and its hitting about 45lbs. I know once I put the new injectors on and the S480 I will be way over 45lbs. How can I adjust the internal wastegate to be more in the correct range for the compound setup.

:ft:

I'd do an external gate.

Get a spring gate, like one stainless diesel sells. It makes wastegate adjustment a whole lot easier..

It will be much slower spooling with a primary under it.
you think it is slow now, wait!

Most prefer a 60 for the secondary.

Take the snap ring off of the actuator and lengthen the rod, put an air line regulated between 20 and 25 psi on the actuator the gate should be wide open by then.

I think I am just going to go through Stainless Steel Diesel for the piping kit which comes with there spring gate setup. Anyone know a better place to get a piping kit for this setup?

Thanks for the info.... I am going to play with the wastegate some more before I install the twins.
