B.O.B MACH 1

I found a used under drive pulley for sale. I heard mixed things about them though. Can someone give me some input. How much hp and tq should i expect from it. I jsut dont know if i should pick it up or not.

dont get them, they have a tendency to break oil pump shafts. which leads to engine failure quickly

You may pick up 2-3whp from them, but that's not even close to being worth the risk. Those who have used them and had problems say don't use them, and those who have them and have beenlucky enough not to have problems give them a good review. Fact is, there have been some Machs that have had serious issues like oil pump shaft breakage, that's enough to steer me away from them. Don't riskhurting your Mach for such a small gain.

sub for a electric water pump instead

Im glad i asked before i bought that one. 3 hp is not worth the oil pump shaft breaking. thanks for the heads up.
