[QUOTE="duckfish, post: 383718, member: 17136"] For those of you that have gone to stainless, have you seen an improvement in fuel economy? Other than speed at WOT, are you gaining the same 1 - 2 mph thru-out your rpm range or is it even better in the middle? Would 3 blade or 4 blade give a better improvement in the middle range? I worry less about top end or hole shot and more about range and fuel economy. Some days I may run 60+ miles and I start to get a tad uneasy about my fuel reserves. I know pretty close what rpm's I'll be running to cruise at say 24 mph, when I have things dialed in. I'll switch to stainless in a heartbeat if I could pick up a few mph at the same rpm & decrease fuel consumption. [/QUOTE]
