Yes it is frendly. Average at the wheel is 156hp COMPLETE pipes 168-171hp 1,000's of Busa fit into this catagory. @ Crank would get hih nmbers obviously. No argument this is the facts.I doubt he could hit 180 hp with those mods... most people need cams to get that high. and I'm guessing thats a very friendly dyno.167 hp stock?That's way cool. If that's a good reading and under the same conditions once you pipe it, remove pair valve, add a PCIIIr, and do an air box mod... you should be slightly over 180hp. That would be totally awesome.
