2H first drive impressions

[Deny]

Aerodynamics have nothing to do with rpms

Are you telling me that 60 series with same engine, same gearing (and tire size), driving the same speed will have the same rpm as a just as heavy 40series troopie. I think the troopie will have to be reving up the engine a bit more to keep up the same speed, just to overcome the wind resistance it is encountering, no? And the faster it is going (60mph) the more it will affect the truck. Fuel econemy will be affected also I would think.

Are you telling me it wouldnt?
In answer to your question ,yes
Do you know what a rev is?

Which is heavier, a ton of lead or a ton of feathers? Think carefully

I know rpm stands for revolution per minute, but now you are really starting to confuse me with this lead and feathers mumbo jumbo

Just explain to me how my scenario the troopie will not have to increase it's rpm to keep up the same speed as the 60, all things being equal and the troopie having to overcome more wind resistance? I am doubting myself that I am missing something, and I don't want to look like a dummy (I know I try) so I just need some clarification.

yes you are missing something. same rpm with the same setup will give the same speed, no matter how heavy the truck is.
according to your theory your truck would need higher rpm in the same gear to move at the same speed, when fully loaded. not happening.

it will use more fuel, or it won't be able to do the same speed, but the relation of speed to rpm is a constant that is independent of weight or wind resistance.

unless your clutch is still slipping

When engine turns one revolution it turns the gearbox, t/case,diff and wheels a set amount of times.

This is unchanging regardless of vehicle weight.

The ton of lead IS heavier

Clear as mud now.. Thanks. I didn't know they were reading from the same gear drive.

Update: After putting 35s on the troopy it dropped 500 RPMs on the freeway. It hurt hill power but not as bad as I thought it would.
