V-10 rpm's
I have a V-10 in my motorhome and dont know much about the motor. I have heard it was designed for high rpm. I have a very low geared rig (4 speed auto with o/d) and the manual states that it is 5.38 rear axle.
My question is this. Is the engine really designed for high rpm and what exactly is the definition of high rpm. If I wanted to run it at 3200 for long drives would that be too much?
I have never been a fan of real high rpm but maybe I am behind the times here.
thanks

The V10 starts making torque down at 1600rpm and builds to 80% max right at 2100rpm (cruise top gear fopr most of us) the full HP and Torque is seen around 3600rpm and is fairly flat on up to 4800rpm before she falls of some on up to 5200rpm.
The motor is rated for a 6000 rpm red line and the factory rev limiter kicks in around 5000-5200RPM.
Big heavy class B and C motorhomes are geared low to keep the cruise rpm higher in the power band than us light truck drivers need.
Your V10 will suck fuel like it is free, but as long as your engine and tranny temps stay stable you should not worry any about running up and down the hills at 3200-4800 rpm. The motor will do it day in and day out for as long as you take care to give it clean air, oil , and fuel.

It might wear out a little faster, but I don't think that the average motorhome ins't used all that much... these engines can go 150,000+ if maintained! Otherwise, if it was bad for it, then they wouldn't build it with that low of a rear end in it.

It was kinda suprising to me that even with my 5.38 O/D I am still only turning 2800rpm at 65 mph which is the same as my chevy S-10 in 5th gear!
I guess those 19.5 inch tires kinda equal things out.
