V-10 problems

Depends...on the ICE's torque/hp curve....

The higher numeric diff will allow the ICE to rev HIGHER...therefore more HP delivered

:R :R :R Hmmmmmmm, I have changed gears in my car more times than I can count and it NEVER allowed the engine to rev higher. It rev'ed to 7,500 RPM before the gear change and it rev'ed to 7,500 RPM after the gear change! If the OP does not want to go above 4K he can put 6 to 1 gears in the back and it won't help. In fact, for a given RPM the vehicle will go slower. My tractor has like 20 to 1 gears in it. It's not exactly blazing fast! :B At WOT in low, low it is cooking along at a blazing 1/2 MPH! :E


Look up that V10's torque/HP curve at 4K RPM vs something like 5K RPM...the HP WILL be HIGHER

The OP "does not like" to rev his V10 above 4 grand. He said that. His actual words are: "I have let it to up to 4000 rpm at times but and it sounds awful when it does." It does not matter if he looks it up or not. If He won't let at engine rev above 4000 grand he won't get full power out of it.

I don't care WHAT kind of gear he puts in the rear end; it won't help! In fact, with that load he will more than likely slow down!



Of course...up to the point where torque drops...then HP will likewise start to drop...

At 5252 HP will ALWAYS go up and torque will ALWAYS go down. 5252 is where they will cross. ALWAYS! As Mr. Thomas Andrews would say: "it tiz a mathematical certainty." :B

But...the OP wants to stay lower in the RPM range for 'that' ICE...seemingly wanting
It to behave like a diesel... :B

Exactly!

I have no idea where all of this RPM phobia comes from? It's an epidemic on RV.net and other places. I've tried and failed to cure it. About the only cure for it is a brand new diesel. :B

I'll give it one more shot. There is not red line on any modern engine. You can hold your foot to the floor and it won't over rev, it won't blow up or anything else. I will freely admit it will drink fuel like a drunkin sailor! :B
