kyle and my setup are very different. he's running a log manifold so the smaller exhaust side helps his spool. i'm running a divided t4 full race manifold, so i can get spool faster with still running a larger exhaust. two different ways to make the same amount of power. we're both at 460whp.

i'm running a .91a/r exhaust

i'll be working with borg warner again this year, and we'll be trying out some other wheel/sizing to see if we can better what we did this year.

 

im really curious about the engine, if you dont mind. what rotors? kyle is running s4 t2 rotors which also surprised me... side cut rotors right? 2mm seals?

thank you.

 

fd rotors, e-shaft, crush assem, housings, s5 irons, 2mm stock seals

 

I'm leaning towards a .83 a/r. I'm only planning to build the car to 400hp with lots of bottom end power.

What do you all think?
