how much torque is required to keep a car at 60mph? like 3000lb weight, 0.30 coefficient of drag, 63" wheel circumfrence

did u get the circumfrence by multiplying 20" by pi?

i'm lost on something though. for a 20" wheel to travel one mile per minute it needs to rotate 2933 times right? with all the gear reduction of the rpm it doesn't make sense. like an engine at 2000rpms in a transmission overdrive gear of .83:1 and a differential of 3.75:1 the wheel is only...

i wasnt underestimating, i was making an observation, there are "fake" superchargers called prochargers that use the same design i stated only shove air into the motor, i've been told the suction idea won't work so the idea is irrelevent.

so in the end, god i swear I've re-written this 4 times. so i'll keep it simple more low end torque will increase mpg with smarter driving because...the engine is working more efficiently and using less fuel?

http://www.youtube.com/watch?v=9dKlOCde4Vk&feature=related we ain't in kansas anymore, this is how that mustangs motor ticks. there's a lot of neat crap under that hood.

locked up drivetrain as in like what they use in dirt track races with modifieds? just a forward and reverse hooked up to a planetary gear? how exactly do you not use the horsepower? like give your motor lots of low end torque to cruise on?

like i said above guys, I'm not really into the mechanics of it, I am just ready to make a motor that's wicked fast and gets awesome gas mileage. like the cars in the SEMA competition. i would do anything to figure out how that mustang guy got 400hp out of a v8 and still got over 100mpg cruising...

oh, well thanks for clearing that up, its fine, i took an autotech class, didnt really care for it. speed is more my thing.

well i ment as in, if no exhaust is leaving the cylinder, then obviously an air/fuel mixture isn't going to combust right? which would result in crappy performance.

it couldn't be any more harmful than what your waterpump and oil pump do. far less power extraction than an alternator or an ac. plus, if the cylinder is capable of expelling all the exhaust by itself then why arent we seeing 2 stroke motors now? seems kinda pointless to have a intake and...

so...at this point ur not gaining any hp or torque yea? when does this usually happen in most vehicles?

i don't think there would be a huge loss. you can freely spin a turbocharger with ur hand. i figured running the hot side of a charger through the auxilery belt to drag out the exhaust would be pretty nifty. maybe if there were some changes in design of the motor this could be useful at high rpms.

what do you mean the orifice is choked? like there's just not enough time for all the exhaust to spill out because the exhaust valve closes to fast?
