TT Dart -- Brainstorming

Smaller the housing the quicker the motor will choke which means it will have more back pressure in the exhaust and smaller the A/R the quicker the boost will come in too if your not planing on spinning alot of rpm's go with a smaller exhaust housing the .84 a/r will come in around 2800 on a 360 some of that depends on your set up too.
