I'm just wondering what's normal? Mine seems very high for a v8 2250rpms at 65mph and 2500 at 70mph

 

I believe that's about where mine runs maybe just 1 or 200 less.

 

Thats right where its supposed to be.
Its not the size of the engine is the final drive gear ratio.
Change the gear ratio in the diffs and you can raise or lower the engine rpm.

Bigger tires, lower rpm, smaller tires higher rpm.
There ways to change your final drive ratio without changing the diffs.

 

Thanks.
Yea I know about chaning the final ratio just wanted to check. The discoverys differential ratio is pretty low I don't see why rpms high.

Oh well.

 

Yah my rpm's are exactly what yours are. Mine never has to downshift when I take it thru the Smokey Mtns b/c it revs so high. I guess that's an advantage? lol.

 

I think they have it geared to keep the engine in the power range when cruising.

 

Mine runs at 2900 RPM's at 70 MPH but I am also running 265's with 4:11 gears. As Spike has mentioned, the RPM's need to be in the middle of the power curve when crusing for your best performance. With mine being a little higher, I am actually about 200 RPM's high, but when I put my foot into it, boy does it jump, compared to the factory 3:55 gearing.

 

*please do not use your phone to take stupid pictures while driving

 

If you had used both hands and paid more attention to the task, the pic wouldn't have been so blurry.

At least you weren't texting, were you?

luck,greg

 

Laugh out freaking loud.

No I was not texting, texting is gay.
