Default Offset twin turbo sizes..????
What are the hurdles in this.??? Lets say a 60 for quicker spool for one side and a 70 for the other for some more topend... This is just a thought guys so keep flaming to a minimum.....

Backpressure is not equalized on the turbine side. So basically the engine will be fighting 2 different forces.

Not enough room to run sequential turbo's efficiently in these engine compartments

Could this be remedied by using different exhaust housings and wheels....????

No, but it could be remedied by using two properly sized turbochargers.

A pair of PT61 P-trim .68 A/R turbos will do over 1000 to the wheels without maxing them out, and will be fully kicking by about 4000 RPM's. What more do you want?

Indeed - I think I posted in the other thread about this saying that it was not necessary. In my setup I never see "lag" or have to wait for boost to come in. That may be a problem as I crank it up into the 20s but at 10lbs it was never a problem.

No, the pressure delta will always be different due to the differences in wheel sizes and masses.

Right or a pair of TE44's will spool VERY fast and still give top end. If not go with a set of Dual BB 60's.
