Unexpected side effect from the talk here.

[rusty ol ranger]

Agreed all the way. A good running 2.9l is like night and day compared to a leaky vacuum/rotted harness 2.9l. And the power is there instantly with the low power band. Oh and BTW, It's not nice to drug a porch. they'd give you a year or more over here for something like that.!!.....(long pause)....It sounded funnier in my head.

Thank you!

Everyone bases their 2.9 opinion on some half assed pile their buddy had when they were a teenager that pry had been beaten within an inch of its life.

I bought rusty #1 brand new, and over 300xxx miles it for sure lost some giddyup, but it was STILL peppier then any 3.0 id ever driven.

Rusty 2.0 is the same way now that it runs good. 1st-3rd the 2.9 is a flat out runner as far as small EEC IV V6s go. Up at speed like i said, i think the 3.0 outshines it (slightly) here.

so really what this boils down to is this....

one turd slightly outshines the other turd.

They are both turds

 

[Dirtman]

Put them both in my furnace!

 

[Uncle Gump]

Then it's finally settled... turds go in the furnace.

So if torque dont matter then a 3.5EB making 425hp and 470ftlbs of torque should be able to pull the same load a semi with 425hp and 1300ftlbs of torque right?

Yes, of course it can because it makes the same power - at least at peak power. But of course you have not given the full power curve, or even the rpms of those peak torque and power numbers so the question is unanswerable.

If that 470ftlbs is at 2.77 times the rpm of the 1300ftlb number then the two engines will be identical in what they can do. Just gear the 3.5EB down by 2.77 and it will make the same 1300ftlbs and still have 425hp.

Gears offer mechanical advantage.

Same as using a cheater bar on a ratchet. If you put arnold swartznegger and bob vila behind the ratchets hooked to a rusty bolt and said "first one to snap this wins" then give ol Vila a 6ft bar and leave arnold with just the ratchet its going to appear bob is just as strong when in reality he isnt.

Same deal here. I could take a friggin 5hp briggs give it 100 gears with a end ratio of 4000:1 and get it to move the same load as s powerstroke with a 6 speed and a 4.10.

Would you then say the briggs is just as strong? No.

We are compareing engines, not total packages here. Short of a flywheel dyno the first matchup i posted (2 2nd gen trucks, same gears, same everything) is the only fair way to compare the two. Its not fair to handicap the 2.9 with a 3.45 and help the 3.0 out with a 4.10 because youre giving it the advantage.

Besides its a stupid arguement anyways. The 2.9 and (early) 3.0 make damn near the same numbers but the 2.9 comes on much stronger outta the hole. Yes a 3.0 with low gears might be able to nudge infront outta the hole over a 2.9 with high gears, but once again, unfair advantage.

Put that EB infront of your standard 10 or 13 speed and its not even gonna move 80k past maybe low gear.

Sure you could gear it to the moon and do it, but if you slapped in an ISX rated at the same HP and gave it the same gears its still gonna stomp it.

 

[Uncle Gump]

That would be fun to drive...

 

[Dirtman]

My butt itches.

 

[rusty ol ranger]

You know what?

Piss on it.

Go ahead and find a 3.73/4.10 geared 3.0 and ill still stomp that taurus engine turned sideways, grocery gettin mom mobile engine with my 3.45s.

**** ill even pull a plug wire.

 

[Dirtman]

You also need to put a fat chick in the bed...

 

[Curious Hound]

**** ill even pull a plug wire.

You didn’t specify which engine you would pull that from

Mine.

A 2.9 on 5 is still stronger then a 3.0 on 6.

All true but you have fundamentally changed the comparison. The B&S only makes 5hp, so it can move that same load but not as fast - the rate of work done is less.

In your first comparison you had two engines that make the same 425hp. When you gear down an engine you multiply the torque but the power is unchanged.

I was exaggerating to make a point.

Yes you can "fake" torque with gearing but it doesnt change the fact that the engine with more torque is still gonna get more done regardless of gearing.

Rusty is just about to blow a fuse...
