You might need to make some power....
Cause I can do just about everything you listed, and aside from the 150mph.... I have plenty.
The "hills" near my house are 8%+
I tow MontEagle plenty, it's 6% for something like 6 miles. I always just rock the cruise control at 65mph (55mph speed limit) at my usual 20,000 or so lbs gross.
Other than that, I still tow our skid-steers around, although not as much as I used to now that we have the 550. I did put a gooseneck hitch in the truck a few months back though. Didn't do it because I don't tow.
If you need a 4.30+ gear for a 37" tire, you need more powah. Plain and simple.
More power at 1500 RPM's.
Hmm, other than running twins or water, how do you suggest the other 99% of PSD
owners with lifts and big tires keep EGT's in check??? Other than constantly downshifting or gear hunting?
Heck, on another forum there's a guy wondering why his EGT's are spiking while towing a 5000 lb
trailer. He's running 37's and never changed his stock gearing. Now he has to downshift to 2nd just to go up a long hill with a 5000 lb
load in tow.
I guess running at a proper RPM range is a big no-no now. After all, you preached for so long about how making big torque numbers too low in the RPM range is equating to having sex with your own sheep. But I guess lugging the engine is ok now, right.
Oh, and I lived in SC
for several years, and drove my truck all over SC
, NC, GA, TN, etc. Those aren't mountains. One more thing... while living out there, I also ran my truck with 36" tires and stock 3.73 gears. I'll give you a hint... it worked, but it was far from optimal for towing or even daily driving.
There you go Charles, that should give you plenty to play with. By the tone of your post, you looked bored. Maybe now you'll have something to keep you entertained for the afternoon.
