Depends on exhaust flow, even @ 175 shot exhaust duration and lift should be looked at if you want good performance



On our last combo we ran 3 foggers and about 700 HP worth of spray. When we changed over to the Procharger we used the SAME cam. Yes, there may be a small amount of gain by having a special grind but it's not even worth the trouble with a street engine and a 175 shot.
