I think you guys think a TDo6 is alot larger than you think it is. The thing has the ablitly to spool an SR as fast, or faster than a T3/To4E with like 60 trim and a .63a/r, and make good power. 400hp 400ft lbs at the hubs is the sweet spot for this turbo. I have seen full boost "read" 1.5bar reached at like 3800 rpm's so its not any worst than a t3/t4. Everyone around here uses garret its already know. Time to take it a different direction.
