I am looking to build my own custom twin-turbo set up on my 2016 mustang v6, but I need help.

- What parts?
- What sizes?
- How much boost can I safely run?
- How will fuel economy be affected?
- How will my engine's lifespan be affected?
- Price?
- Is twin-turbo the way to go, or should I single turbo/ supercharge?
- Any other information I should know?

Thanks for any and all help!

There isn't really any value, other than the "wow" factor to going twin turbo. It does look nice under the hood though.

As far as boost, do NOT go over 8lbs or so on the 3.7. It will not handle it from my experience. I had a single turbo and blew up 3 times - second was due to overboost (a 7 lb spring gave me 15 lbs of boost and I couldn't get out of it in time)

If I had it to do over again I would go with the ProCharger instead. It is a proven and reliable boost system for the 3.7. There are some guys doing twin turbo and single turbo kits but I don't know much about them.

Besides, in order for the twin turbo to work right, you need to separate the left and
right banks, so each has its own turbo. As said, one turbo is enough for the 3.7,
and limited boost.

The setup for a twin should be like this:


This is the ProCharger:


The 3.7 would need rebuilt with the right parts for a twin, and for good boost.

Depends on what is meant by twin turbo? Sequential turbos or two that are the same size to run one turbo per bank of cylinders? Either way, the advantage is the same, less turbo lag and a broader torque curve.

To run one turbo per bank would require an entirely different intake setup as already mentioned and isn't really cost effective.

A sequential turbo setup would mean you could use either two smaller ones in sequence or a two different sizes in sequence for higher output.

Good to know, I had heard that a twin turbo setup was superior to a single turbo when there were two piston banks (V-shaped engines). Also, do you know rough HP gains from that quoted 8 lbs of boost?
