Going a little fast there bud

... tires are expensive. Tires that do not come apart at that speed are really expensive. And they will not take all that centripetal force and heat for very long.

 

It's a lot harder today with 1800 rpm motors and the firm governors. Just taking a truck with tall 24.5's, 0.73 OD, and 3.36 rears from 2100 to 1800 drops you from 109 to 93mph.

For a frame of reference, that truck would turn 1150 rpm @ 60MPH, which is as tall or taller gears than any downspeeded fleet truck.

That should also let you younger guys see that the old school really fast trucks were turning serious rpm unless they had a set of sticks that were both turned around. Or liked listening to the screaming of an RTOO-13 in the big hole. LOL

It gets oddly quiet after 100 mph in a big truck.

 

Yeah, too bad about the 45 m.p.h. speed zone, lol... I always told my nieces & nephews (as they reached driving age) to go out to the middle of nowhere if they wanted to speed, and head for the dirt if they wanted to get crazy behind the wheel and spin a few donuts or brodies. Any venue where there were no others around, ya know? My friends & I would take our rice rockets out to Anza-Borrego and go "a hundred and a half" out there on those empty desert roads... slow down to 90 m.p.h. or so for the broad curves, and WAY down for the twisties, lol. Worst danger out there was the windblown drift sand on curves, ya had to watch out for that sand in the tight curves. Otherwise, the riding was WIDE OPEN, and that warm desert sunshine would heat the road surface and make your tires sticky, lol. The most dangerous part of those rides was going through traffic in San Diego on your way out or back home...

P.S. There were several two-lane blacktop highways in San Diego County which we called "death routes" due to the high number of fatality wrecks involving all kinds of vehicles. Those were CA-78 (or SR-78), CA-79, and Old Highway 94 (CA-94)... heaps of people have died on those roads due to the tight twisties, skinny lanes with no shoulders, impatient fools trying to pass on blind curves, etc.

 

(2150 engine rpm X 60 to convert minutes to hours) =193500
divided by
(3.55 rears X 470 big rubber tire rpm X .73 eaton 18 speed top gear) = 1218
193500 divided by 1218

106 MPH

gotta love math lol

 

Old school "Monfort Lane" comes to mind

 

Quiet in an odd way. Before fan clutches, an engine fan turning 2100rpm was not peaceful in my mind

 

2100 bad enuff..,try a V8 maxidyne some youngin disconnected the rpm gov....pull to just shy of 26....too loud to think
At least that’s what I’ve been told

 

That's probably the only way you could NOT think of how fast them 32nd's were coming off them drives!
