Op you’re not going to see a mpg increase from changing pullies on a pd blower. If you’re concerned with 2 extra mpg, you’re driving the wrong car lol. Both my CtsV and s4 have small snout/large crank aggressive pulley combos and both get good mpg when I’m light on the go pedal. Driving like a grandma is your best bet to improved mpg...

I wouldn't say I'm concerned with mpg really. I just finished off a few tanks of Sunoco 260 GT

I was just doing the math and figured that a larger pulley would pay for itself in one winter if I gained 2mpg. I might not get that, but I should see something by spinning the blower slower. I have zero traction on dry pavement with the snow tires, so might as well try to save gas. I'll already be driving like a grandma on those tires.

• Engine and transmission friction increases in cold temperatures due to cold engine oil and other drive-line fluids.
• It takes longer for your engine to reach its most fuel-efficient temperature. This affects shorter trips more, since your car spends more of your trip at less-than-optimal temperatures.
• Heated seats, window defrosters, and heater fans use additional power.
• Warming up your vehicle before you start your trip lowers your fuel economy—idling gets 0 miles per gallon.
• Colder air is denser, increasing aerodynamic drag on your vehicle, especially at highway speeds.
• Tire pressure decreases in colder temperatures, increasing rolling resistance.
• Winter grades of gasoline can have slightly less energy per gallon than summer blends.
• Battery performance decreases in cold weather, making it harder for your alternator to keep your battery charged.
• Icy or snow-covered roads decrease your tires' grip on the road, wasting energy.
• Safe driving speeds on slick roads can be much lower than normal, further reducing fuel economy, especially at speeds below 30 to 40 mph.
