So I have decided on the BW 7670 turbo, and not quite sure on which hotside to get.

.83 T3 single scroll, or the .92 T4 twin scroll.

Short term power goals are 4-500WHP (its a track only car) on the 2.0 motor.

Anyone got experience?

 

what manifold will u be using, I would lean towards the t4

 

^THIS. After seeing how well the T4's flow/spool on a twin scroll on this motor, I highly recommend a T4 as well.

 

If you go with a divided hotside t4 is the way to go

 

Ill just be making a manifold I think. Just wondering about the AR being so high on the T4.
