It’s probably got more to do with that fact that you are generating boost, than the strain of the pulley itself. ---

Well cruise control at 70 doesn’t create any positive boost, it’s still negative. Or are you saying IT IS generating boost because at idle it’s at about -9 lbs and cruising at 70 it’s closer to 0. I would have to give it some gas at that point to bring it above zero. Disclaimer: I am NOT a boost expert. ---

What are those cars rated at? And really ron? 40’s in a Cruze? That’s outstanding. ---

I just got 23mpg in my 10 year old, 300hp, V8, autotragic, 4000#+, Audi at about 75mph on a trip to Cleveland and back. That includes some city driving and slower construction driving. Didn’t even stop for gas the entire trip. 🙂 ---

So far I’ve only gotten a best of 19 mpg highwy on the mustang but it does have 410 cubes and 525 flywheel horsepower. But when I compare that to my 1998 v6 165 hp awd explorer with 165K on it that gets the same mileage, that makes me feel shitty about my truck and good about the mustang ---

how are you getting 35mpg out of a 325i? thats really good…the most i have gotten is about 27-28 in my 323i 5 speed (which is still the 2.5l) i am talking actual numbers, not the silly gage in the cluster. as for the question about mid 20’s being good, it depends on who you talk to. anything breaking into the 20’s is good for me, considering my s10 was getting 4-5mpg. ---

I’ve been pleasantly surprised lately to see 34+ in my b5 a4 1.8t with 173k on the clock. I only see this sans roof rack though. The rack really kills my mileage. My moms TSX is a champ (fry) ---

New rule don’t post a car with less than 300hp in this thread because if you have less than 300hp you should be getting 40mpg or it is not worth owning. 😃 ---

I have the same exact car, it’s not too bad if you stay on the highway. City kills it, I avg around 22-23mpg depending on how traffic is for the tank of gas. Seems like cruise control doesn’t help at all, better off loosing a mph or two then flooring it to not slow down lol ---
