Yes, your only going to achieve similar power to td04 @1bar with an increased spool time. But it does have a massive amount of torque, and the way I saw it was once it were forged it was 1.5bar ready! Don't get me wrong I'd have run a td04 happily but a friend gave me an awesome deal on a manifold downpipe and td05! It sounded insane when it hit a bar and the external spat evil out!
