Dang, they must be quick as hell. Wouldn't that be something like having 4.88's with 4-speed trans?

 

Talking to a guy with a "crewcab" and he claims 21-22mpg highway and has beaten an SRT8 charger from a rolling 20mph. Also claims it will break the tires loose at 20 mph.

I don't think its that quick... but it sure sounds quick with 4.30 gears and a 6-speed trans.

 

Toyota's

1st gear 3.333

2nd gear 1.960

3rd gear 1.353

4th gear 1.000

5th gear 0.728

6th gear 0.588

 

Compared to GMs

1st Gear 4.027

2nd Gear 2.364

3rd Gear 1.532

4th Gear 1.152

5th Gear 0.852

6th Gear 0.667

The 4.30s come with the Towing Pkg...otherwise, 4.10s are standard. All others come with the 3.90 rear. (I believe) I have a Reg. cab with the 4.30s and, yes, it's damned quick. The Dodge Ram guys with their "Yeah, its got a Hemi" decals in the rear window have been mighty surprised. Just sayin'...

So your Tundra actually came with 4.30 gearing in the rear end? Unlike GM which puts 3.43 in the back then the lower geared 6spd compensates for a final gear ratio of like 4.10 or close to it?

Wait, what? I'm obviously missing something.

 

I was under the impression that the higher your gear ratio, the MORE your engine has to turn to get an equivalent number of revolutions versus lower gears. To me that translates to lower speed but higher torque which makes sense with towing packages. Please correct me if I'm wrong.

Yes, but the engine can rev up quicker because the greater mechanical advantage through the gear ratios. It will be quicker but the top speed will be lower. Quicker does not mean faster. Faster=Top Speed

You are correct, sir! Lower numerical ratios permit faster acceleration but the increased revs limit top end. Tundras have a limiter that cuts power at 107 mph anyway. At least that's what I've read. I've never had mine over 80. If I wanted speed, I'd get one of them new SS Camaros! :rolleyes:

Theres no way he beat a SRT8 Charger, They have 425 hp and only wights 4,200 pounds, dose the 1/4 Mile in 13.5. The Tundra dose the 1/4 in 15.1. I call it B.S. they might be fast but not that fast. :rolleyes:

Toyota's

1st gear 3.333 x4.3 = 14.33

2nd gear 1.960 x4.3 = 8.428

3rd gear 1.353 x4.3 = 5.81

6th gear 0.588 x4.3 = 2.528

 

Compared to GMs

1st Gear 4.027 x3.42 = 13.81 (15.02 w/3.73s)

2nd Gear 2.364 x3.42 = 8.08 (8.81 w/3.73s)

3rd Gear 1.532 x3.42 = 5.24 (5.71 w/ 3.73s)

6th grear .667 x 3.42 = 2.28 (2.48 w/ 3.73s)

 

Looking at the final drive ratios for the first 3 gears (typical acceleration) and OD (for highway gas mileage) the 4.30s in the toyota dont look like anything supernatural.. It's got a slight advantage (NOT MUCH) over the gearing in the GM with 3.42s in terms of acceleration, but then the GM 6spd and 3.42s win in gas mileage. And then if you put the 3.73s in the GM 6spd, the GM win in BOTH acceleration AND gas mileage

 

^^ generally speaking of course... only in terms of final drive gearing.

 

PS: I drove a Toyota before I drove the GM.... Even with the nannies, the GM 6.2L/6spd/3.42 combo was easily noticeable as the better truck... and even though my last truck was a Chevy, i had a ford explorer before that. And i was considering the new Toyota AND the new Dodge... so im anything but brand baised..

I would believe that. My best friend has a 2008 5.7 and it is hella quick for a stock truck. From a dead stop, I don't know if my Black Bear tuned 2007 vmax will hang with him and I can break the tires loose at 10mph with a 4 speed and 3.73s with 20 inch rims.

 

 

 

 

Theres no way he beat a SRT8 Charger, They have 425 hp and only wights 4,200 pounds, dose the 1/4 Mile in 13.5. The Tundra dose the 1/4 in 15.1. I call it B.S. they might be fast but not that fast. :rolleyes:

 

 

I don't know. I am sure he would not out run one from a deads stop and with both having traction, but with a 20mph roll, I bet it would be close. I have witnessed low 14's from Tundras with nothing more than exhaust. That 15.1 may be a 4X4 crew.

 

 

 

Most people only know gear ratio's and not final drive ratios. I think that has hurt GM some with the current 6 speed set up. People are constantly posting on here about how are they ever going to tow anything with 3.42 or 3.73 gears that come with the current 6 speed set ups. But in reality the 3.42 paired up with a GM 6 speed is as good or better combo then a 4 speed with 4.10 gears.

 

Remember, transmission gear ratio, rear gears and tire height all come into play with final drive ratio.

 

 

Edit: Skier did the calculations for us.

No doubt! I gave up trying to explain this to people many months ago. It is futile.

I too test drove a Tundra Crewmax 4x4 and that truck definately has some giddie up! GM should steal a page out of Toyota's book and get rid of the torque managment in their engines and get their engines to accelerate like the Toyota 5.7L! However, I still cose the the Chevy over the Toyota for the following reasons, Rear locker, Gas Mileage, 2 Mode 4x4, overall interior looks, overall exterior looks.

The 6.2l 6 speed combo will run with and out run the Tundra (depending on setup) in the 1/4 mile.

I'd run my truck against a Crewmax anyday (well, with lighter tires anyway...or at least equivalent tires). :rolleyes:

^^ True Story. I drove the yota with the 4.30s and my Sierra Denali (3.42s) back to back and the acceleration felt about the same... but the GM just had a smoother feeling acceleration (yota was jerky..) and just had overall better riding characteristics.

 

Considering my truck with 3.42s performed like the yota, i think im going to have to find a 6.2L/6spd with 3.73s to take for a test drive... just out of curiosity :rolleyes:

 

Edit: dont get me wrong, im sure the Yota would take my truck in the 1/4... but not by much and its not a difference you'll notice by just driving around

Has GM offered the 6.2 with 3.73 rear end yet?

 

I think a lot of people don't bother to look up transmission ratios so they assume with 3.42 gears it will be a pouch. Adding the 3.73 ratio will be as much for PR as anything else.

      I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      My office is slowly filling with Blazer parts. Getting ready to do the big bang of repairs. Intake (second time), water pump, radiator, hoses, and I'm going to re-seal the timing cover where someone went hog wild with silicone. Might as well, because I don't think that's done right.   There's a local tow yard that I didn't realize also has quite the inventory of junk vehicles. This is an old school junkyard. No waivers. Cash only, you were never here if anyone asks. Don't piss off the owner, or you'll end up in the back of one of those cars, headed for the shredder. And if you see something, don't snitch. Cars stacked double high, wasps nests, trip hazards and junk everywhere. I found a few little odds/ends for my Blazer. The $20 I spent was worth the experience alone. But I was never there. What yard?   I officially love/hate this truck. It's so out of my wheelhouse, roughest vehicle I've ever owned. Every. single. repair. -is so hard-fought, everything that can go wrong, goes wrong. Currently in a hate phase, and kind of wish I was closer to sending it down the road with a lucky new owner, to be honest. Preparing for the day when I tear into this thing...lots of pre-funk with Ibuprofen.   Rock Auto sent me a bad reman rear wiper motor. It was a bear to install. The tailgate in these things has about eleventy-billion fastners and pieces and things that need to be uninstalled/moved just to access the shoddy rear wiper motor. The casing on mine was cracked clean through, btw. Nice, GM, nice. SO I got this new motor installed, hit the switch, I see it wig-wag (without the arm installed) and think I'm golden. Reassemble everything. With the wiper arm installed I gave it one final test. Time to clean up and take the other half out to dinner, collect a paycheck, right?   Nope. I hear the plastic worm gear stripping as the arm hung up. Just like my broken motor. Weak/old and shredding itself internally. I can assist the arm and the range of motion is normal, and it parks correctly. It just doesn't have the poop to actually sweep the arm with a blade on it. Oh, hell. Turned the key off and shut the shop door behind me. I get to do that over again, too.

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.
