Im not saying a single turbo or twin turbo is better....Alot of Gtr, Supra guys go for a huge single turbo due to the simplicity, and also theyre alot cheaper, but dont forget, if you have a smaller turbo feeding a larger turbo; you wont have lag, you'll still get the big turbos higher rev range power, the supras used this kind of setup bloody we'll, Gtrs on the other hand didnt use the sequntial turbo system theyre.....Im sure HPF are good guys and know what theyre doing im jus stating a point that this is something no one has yet to try and im damn sure it'll get people results....also on a side note, has anyone here tried using a ford 9inch detroit locker???
