Gained 9mph by adding 190 hp. I have purchased an XR upper and -2 Imco lower, but have not installed them yet. From speeking with other Victory owners, i expect it will pick up considerably with the outdrive swap. I am also running the stock 454MPI intake and plan on swapping it out this winter. I am sure it is costing me lots of hp and rpm. I think with these 2 changes i will get to 70, but you never know.

On my engine I just could not find the room to add a procharger. I only have 1" between the crankshaft pulley and the back of the seat. Would have had to completely redo the seat and engine cover to install one. Yours may or may not be the same.

Good luck
i agree,the 454 intake is definitely costing you quite a bit of power...there's a couple of places that port/modify them for more air...with a goal of 575hp,i think you'd still be at the limit of that intake...got that info from eddie young a while ago
