More power

[kurek]

comparing a electric ceiling to a truck engine is silly
.

Yeah that's the point. People say DIESELS MAKE MORE TORQUE, ELECTRIC MOTORS MAKE MORE TORQUE! but those statements are meaningless. There are tons of diesel engines that make very little torque, there are tons of electric motors that make very little torque. For any diesel or electric prime mover anyone cares to mention, there's nothing in the world preventing the construction of a gasoline engine that makes more torque.

The only kind of motor that makes more torque than another motor is.. uh.. you know, one that actually makes more torque. The method is irrelevant.

I don't think it's meaningless. Of course more torque is more torque, and doesn't matter what kind of motor (diesel/gas/electric). Where it does matter, is where it makes that torque. The new EcoDiesel makes 480lbft at 1600 RPMs the new Hemi makes 410lbft at 3950 RPMS. Electric motors make their torque from zero RPMs on. Torque is what drives the vehicle forward and the sooner you get it, the quicker you start moving.

My 3.21s will easily spin the tires too. The pulsar in performance mode definitely stops any lag from the solonoid driven gas pedal.

 

[Gary2]

All the tire spinning is great for show. Its when it hooks up that the right gears walk away from the under geared , then add 35's or better and gears become even more significant. If Dodge still offered 4.10s in a 1500 I would still have them .

 

[89grand]

The 3.21 combined with the 8spd's 4.71 1st gear, has a lower effective 1st gear, than the old 6spd with a 3.92 rear. In fact, to put it in perspective, the old 6spd would need a 5.03 rear gear to have the same effective 1st gear as a 3.21 8spd.

No doubt the 3.92's have an advantage when towing, and even off the line with the bigger and heavier trucks, especially with larger tires, but a 3.21 in a stock single cab is more than enough gear. The ease in which mine spins the tires now, would only be worse with 3.92's.

That's because you have a 2028 truck......

If you want to see what a hemi can do save your money and don’t waste it on CAIs or cams ect that can be done after the blower kit.Trouble with all the bolt ons rams have to have the pcm and the trans unlocked,after that it’s all worth it.And unless the computer is lying I’m getting much better gas mileage.The amount of boost is small the results are big.

Everyone acts like 3.21's are a dog, but my truck can spin the tires with ease, even after mashing the gas at 15mph or so.

Maybe they are a dog in 4 doors, but not in my single cab.

Anyone can spin the tires if launched correctly. If you're spinning, you're not going anywhere.
It's made possible partly by the sh!tty stock tires and especially so if you have the 8 spd.
Once the tires stop spinning, you are back to your 3.21 Highway gears. 3.92's will out pull your 3.21's all day long.

I think you're not understanding the concept of shorter gears.
Your tires would NOT spin any "worse" with shorter gears.
At any constant RPM level, your 3.21 geared vehicle's tires would be spinning faster than the 3.92 equipped vehicle.
Shorter gears allow you to bring your engine up to a higher rpm and therefore, a higher HP output without burning the tires off the rims. Kind of like the Granny gear in an old pickup truck. Nobody used the 1st (Granny) gear for regular driving. Just 2 - 3 - 4 were used. Granny gear with a very high numerical value was only needed to get heavy weight moving slowly, WITHOUT spinning the wheels. Engine rpms would be higher, allowing the engine to produce more power but limit the rotational speed of the wheels. Spinning wheels don't pull anything. Don't believe me, go rent "My Cousin Vinny".
Short gears multiply torque, not rotational speed of the wheel.

I think you're not understanding gearing. "Taller" gearing, is lower numerically. 3.21 is "taller" than 3.92. 3.92 is lower or "shorter" than 3.21. Gearing is about torque multiplication. The lower (higher numerically) the gear, the more the engine revs in any given gear at any given speed. So yes, a 3.21 geared truck will go faster at 2000rpm than a 3.92 truck at 2000rpm, in final drive, but the 3.92 truck's engine will be reving higher (torque multiplication) for any given speed.

I really don't need to watch that movie, and I am familiar with it, to know this.

If one is spinning the tires at will with 3.21's, they will only spin them worse with 3.92's.

This thread reminds me of an old TV commercial where the two men are going to fight. One fighter is some kind of martial arts type jumping all around waving his arms all over like his ass is on fire trying to scare the other guy with his show hence smoking tires. The bell rings and the other fighter just walks up and punches the showman in the face and knocks him out , end of fight.no show needed. Seems very similar

Have you tried this?

Very neat! I like the clear lexan CAI cover.

It's definitely your gearing the Ford probably has a 4:11 rear. I have two new rams one is a 3: 92 anti slip I tow with, the other is the same truck but has a 3:21 gearing. Out of the hole the 3:92 Blows the doors off the other. P.S. they are both 8 speeds. Remember the higher the number the lower the rear.

Gears are your biggest bang for the buck by far!..
In the 70's, I had a '72 Camaro with a '68 327 motor I built, a Muncie M22 Rock Crusher, close ratio 4-spd. 4th gear was 1:1. No O.D. at all. I put 4.88's in it and that car would just LAUNCH! It also lost a lot of top end speed.
I lived in North Jersey so, my Jersey guys will get this.

But man, it would just riiiiippp:
waaa, waaaa, waaaa through the gears!

You caught my typo. I cut/pasted some of my reply and inadvertantly left in "taller" instead of "shorter".

Not trying to be snarky or incinuate anything about who knows how much. It's obvious you know what you're saying. I've wrenched all my cars, trucks, bikes etc. for close to 50 yrs and I believe that qualifies me to respond as best I can here. I'm only looking from a different angle.
If we take this to the rediculous, say we have 9.88 gears. If you mash the gas and you have good tires, 9.88 gears would simply turn very slowly, moving the vehicle fwd and allowing the engine to climb in RPM's without ever breaking the wheels loose.
That's all I'm saying. If I step back and look at the whole situation, it appears the tires are not providing enough friction, allowing them to break free. Game over when that happens.
OK. I'm done. Let the young guys finish this up.

All it takes is a simple tune on that diesel and its going to be pretty quick for a heavy truck.

My 07 6.7 Cummins had a 125hp tune with efilive and was a beast, installed a bigger turbo running 60 plus lbs of boost and walked on a few trucks easy.

thats why low gears are a win win for me as I live at the shore ( LBI )
