ORIGINAL: jonus079

but remeber, our argument was that you could have 400+hp and still achieve 30mpg on the highway. i specifically stated 400hp, not 300 not 250, 400:

" You are really going to sit there and tell me you’re gunna get the same or even similar gas mileage to a factory 1.8t just cause you are cruising on the highway? Please show me someone with over 400 hp who is still get 30mpg on a consistent basis or even close to that. "

btw i went ahead and made that post in the off topic section. feel free to flame.
you do realize how power/torque is acheived and made on an internal combustion engine don't you? and more importantly, how it is delivered?

well let me get you up to speed on that last bit in a somewhat short explanation.. that "400hp engine" (we'll use mine as an example here) does not deliver that 400hp throughout the entire powerband. my engine spinning at 6000 rpms, with 25lbs of boost mixing with maxed out 440cc injectors will make 400hp. but only for a short time.. just look at any dyno plot posted ANYWHERE. there is a torque curve and a hp curve(hp is a calculation derived from the torque prduced from your engine. HP = (TQ*RPM)/5252) this is why you will always see the hp and tq lines cross at exactly 5252rpms. everytime. the curves start low at less than 100hp, then rise to their peak hp a tq. like 400hp for this example.

if you notice when watching cars on dyno's, you'll see them "cruising" along on the rollers before they start. usually about a 50mph cruise, then they drop the hammer and the hp and tq curves start to rise and they eventually maxout then they stop.. on most dyno plots you'll see a section that states: "hp at 50mph = 50".. that is the power used to maintain that speed, at that rpm. no cars are using all of their potential power all the time. while decelerating, cruising, or at a slight acceleration, most cars don't even use half of their potential power.simply, lessair/fuel mixture= less power. and less power = less fuel consumption(pretty much a "A = B and B = C" equation)

you need to pay attention to the amount of air and gas that is put into the engine. as that will determine a majority of you MPG..

as of right now, my motorhas the potential of putting out 400+hp at any time. but on average with 90% city driving, i get 25 mpg. on the highway, i get over 30.

there, i explained it in the only way Cincy or others haven't yet. maybe this will make you understand. if not, if you don't believe common sense and real world experience, then thats up to you..

but either way, just DROP IT

Re: how much do you put your b6 thru?

I get about 35 - 36 (via the math) on the interstate with the cruise on 80-85. I guess if I were to pull right on the highway from a gas station and get off and go right back to another gas station I could probably get that as an "average." My best average when traveling is usually around 28 as once Im in stop and go my mileage goes down to 15 or so. Crusing everything breathing with a BT FTW, BT and fat injectors in stop and go FTL

siht when i went bt i was getting like 5mpg with the way i drive. you can get great gas mileage if you stay out of boost and drive like a grandma. it is possible. but then again who has a 400hp audi that drives it slow????? i forsure didnt ever take it easy, i spent all my money on that car i might as well drive the hell out of it

To whoever said the insurance is much higher.., it depends... i really wanted and want to sell mine for a nagaro blue s4 2005... called my agent, i figured it would be at least $50 more but it went from $105 a month to $106 if i got an s4 but the 10mpgs4 screen names scared me off lol! they said they get 20mpg if they cruise at 70mph! if they drive hard, 10mpg at best...
