twin turbo gauge question?

[250sprayboy06]

when you have twin turbos do you jus need to replace your boost gauge w/ a 100lb boost gauge or keep your normall 60lb gauge. or get a 100lb an 60lb gauge an use both of em? i would thank you would only need one 100lb gauge? but idk...

You can use 2 different gauges to moniter the pressure from one turbo to the next and the other for the total boost your manifold will be seeing. A drive pressure gauge would also be a good idea and aid in gate tuning.(Assuming you have external gates.)

That all depends on the twins you are running and your relative power level.

Something like BD tow twins or a stocker over s400 top out about 60psi so you are good with a 60 and a 30-35 gauge.

If you are making more power and seeing boost over 60, then yes, get a 100 with a 60.

I can see 90 psi total boost and will see 45-50 from the primary and use a 100 with a 60.
