RPM question

sounds normal

larger engines don't have to rev as high to maintain speed.

unless your audi is a v-8, it sounds about right... the fewer the pistons, the higher the revs/red line...

2100 does sound low at 75 mph tho (we're not talking metric here, right?) i'd think that 2100 would be at about 65 or 70 mph?

probalby has low (numerically) rear gears

I had one a couple years ago that turned 1600 at 60 in 4th, it had 2.73's

That's the benefit of Overdrive.

Sounds just about right, same as my 95 pu

Thank you everyone who responded. I'm still kind of amazed at it, but I'll just enjoy the fact that if it was 3000 RPM on the highway, I'd get a lot worse gas mileage. On that topic, what kind of gas mileage can I be looking at for this truck? I filled her up as soon as I picked her up, haven't had to fill it again yet.

Thanks again. Bill

My 99 K2500 gets around 14 MPG traveling down the highway at 75 MPH with the tach @ 2500 RPM.

Sounds normal, and like you're running 3.73's... :)

You should get around 15 for intown driving 17-18 on the interstate(depending on how fast you drive).

Sounds right..........mine is a 95 Z71 5.7 auto and at 70 mph the tach is around 1750 rpm.......2.73 rear end.....180,000 miles and keeps on ticking! MRT

Barely broken in. My 95 has 216,000 miles & doesn't tick at all!
