Not saying that.

That sheet does not have much info. I would hope the owner of the engine received more info than that. If he didn't, he didn't get much for his money, other than, well, a sheet.

SB, i never see you question a dyno sheets validity when it was a marine kinetics build. But foxwells name is on that sheet, so it must be bullchit.

Still havent seen a dyno sheet , posted from anything youve built or dynoed
