After putting on the TA heads with the .85 housing, my spool up is instant. Anything at a roll is insane. High flowing heads seem to spin the turbine wheel a lot quicker. I assumed the opposite.. Boy was I surprised after hitting the Tbrake in the driveway for the first time!
Since the new combo, the car has been described as "Violent" at 18psi...lol
I did notice the car pulls very hard all through 3rd.
