A while back I heard the 4+3 was in the range of 17% loss. If that's somewhat accurate. I am around 522 hp and 566 tq at the crank with what I believe is a restrictive exhaust system. I will be making a little exhaust change very soon, and hoping to put it back on the same dyno before the snow hits. I am "hoping" to improve on those numbers..... I would like to see 450rwhp, and I really dont need any more torque but you never know I could be as high as 480rwtq. Big block tq is fun foresure. "If" I reach those numbers I certainly cant ask for much more from those little ports. Changing out the reasonator for an x-pipe..... |
