x2 on this. The Ford V10 needs to rev to produce power, more so than many truck engines, and with ten cylinders it sounds like it's about to self-destruct...but it isn't, and it can operate like that as long as is needed.
That said, you of course are not going to get car-like acceleration out of a class C motorhome...even little economy car-like acceleration.
wow... ok - any other advice?
Hmmm ... what really would you like to improve?
i.e. - Do you need/want more horsepower than your V10 puts out at it's maximum of 305 HP ... or is it's 305 HP maximum probably OK ... but you just don't like the way you have to use the engine to tap it's horsepower?
Note that many of the diesel engines that power and/or pull RVs have horsepower maximums considerably less than 305 HP. It's just that these diesel engines have high crankshaft torque at whatever HP they are putting out ... and that they put out this torque and HP at lower crankshaft RPM values due to the inherent characteristics of diesel engine technology.
The only torque that counts is the torque on the drive wheels' axles, and how you develop this torque is by converting any raw horsepower that the engine is putting out at any given engine RPM into drive axle torque through use of gearing between the engine's crankshaft and the drive axles.
What the above means is -> you must tap whatever of your V10's horsepower is needed to push along your particular RV at any particular speed on any particular road grade. How you call into play your V10's horsepower is to rev it up to whatever RPM is needed to produce whatever horsepower is needed so as to convert this horsepower (using the proper gears) into the needed torque on the drive wheels.
For the V10, more RPM is needed than what we are used to from good old truck V8 gas engines and diesel engines. We have to just get used to the sound ... along with any anxiety that our V10 may break while making it's horsepower!
