Twin Borg Warner 177268's with 1.22 ar on a 5.3.
Ready, set, go!

 

I wouldnt do the 1.22's but depends on how much rpm and application. Drag only on t brake it may work ok but that turbine is already good enough size, i would stick with .83 ar street strip, no more than 1.0 in race car. Spool time would be really delayed with a 1.22

 

Thank you for your reply!
I agree with you completely.
I found a set of these locally and just thought I would ask .
Think I will stick with a single 76mm.

 

Good Call on the 76mm.
