A thought

I cut the previous thought,

We got a Truck that runs with some Diesels, and they know it cause my superduty ran good, but at nearly $ .50/gal cheaper and getting better milage when driven the same or faster, i'm happy as pie i'm not buying diesel anymore.

Any thoughts?

Thoughts? Yeah, I am thinking you have no clue about gearing.

Correct, higher number lower gear ratio.

3.42 is a highway gear, good for fuel economy. Not good for towing or for quick accelerations. I had a CC Silverado with 3.42's, I liked them but the truck was a dog off the line.

I believe a RCSB Tundra with 4.30 gears, 5.7, 2WD runs in the upper 13's completely stock, that is pretty damn fast for a truck.

Just bought my 08Tundra Dbl Cab 4x4 SR5 after having an 07 Silverado Duramax Extended cab for only 8 months and 2 of those I couldn't drive after heart surgery. When I bought it diesel wasn't too bad then after I was able to drive it started climbing and never stopped. I was lucky to get out of it when I did. Seemingly better mileage , not as many trips to the fuel pump and don't have to drive 10 miles round trip to get diesel either. Plus I think I have a better truck overall. I know one thing I won't get stuck on a grass slope with these stock tires like I did with the Duramax! Love the truck !

I'm thinking your a a really nice guy but, that could be my clueless thoughts.

My gearing thought is that our engines make more torque than Hp so with lower gears takes advantage of the torque and lighter vehicle allows it to actually accelerate in 1st gear instead of rev out, but i'm sure our a drag racing wizard and your short smart a?? answer tells me so. Since i came from a Torque Diesel my point is proven, the 4.30 gears in my truck made it noticeably slower, yet with a load it was head and shoulders ahead of that highway gear guy pulling equal loads. For instance a SVT lightning, is much faster with taller gearing and using the torque and shifting less, than with 4.56 gearing a NA car would use since it's more of a torque monster than anything, but your the expert.

There is such a thing as trial and error, and this tranny in the Tundra has a very low 1st and a tall 5th & 6th to run such low rpm at highway speeds. Yet my 300C Srt8 ran high low 13's and occasional high 12's on stock gearing and it was 3.06 so explain your theory about that? (a 4400 lb sedan) yet it used it's tranny and gearing to maximize what it had, shorter gears( higher number) would have been good, yet would have resulted in even worse tire spin and bigger traction issue, yet i would have been faster. Although i was referring to a standard cab 2wd model Tundra, lighter truck. 4.30 gears may not be as fast as say 3.73 gears if it's matched to the truck mph and tranny shifting. ONe extra shift could cause a couple tenths of a second which could make a 1/2 sec. ET difference.

I thought this forum was about input, not ridicule and the really nice guy namely V-max2007

I feel what your saying, finding diesel pumps in some towns is terrible, when i bought my superduty I could buy fuel for under a buck, just hate that the fuel was tearing up the fuel system in the older engines, zero lubricant going from 3000ppm to 15ppm of sulfur is terrible for engines that aren't designed to run on the Ultra low sulfer. So i'm saving with each gal of Regular as are you. I concur, love the truck.

Very well put. Its nice to know that others feel the same.I never had the chance to drive the older diesels but I have heard many stories about this new fuel. Too bad there aren't more Bio diesel plants around. That might help the cause a bit. In the meantime I will have a real insight to every one of those guys I see filling up at the diesel pumps now.

Ok then why don't your Educate all of us about your Vast knowledge on gearing dynamics and effective mulitplication of transmission gear ratio, factoring in Torque Converter stall speed and lockup, shift delay, and total time wasted while shifting when you could still be accelerating.

The use of a lower gear for a lighter 2wd standard cab truck has speed benefits not pulling its right in between economy and pulling, explain to me how it would be faster in 1/4 mile with 4.30 gears than with 3.42 ? How much racing experience have you? Please shed some wisdom on us clueless Tundra owners, since your so supreme, you can't help a guy out, you have to put someone down to only make yourself seem as though you know something? Yet you have explained zero...

What is a person who claims they know gearing or anything for that matter only to just make accusation and claims? a fool that's what. test my theory and see if i'm not correct. Now when it comes to pulling and being a truck i'm glad i have 4.30's yet i'm betting that 2dr 2wd that ran in the 13's was a 4.10 truck. So with your thinking any vehicle with higher gears is faster,,

OK your Brilliant. but Helping enlighten someone on why you feel he's off base is not your strong suit.

Wow, you might want to lighten up a there a bit dude. I can see your veins popping from here.

I never said lower gears will make it faster, but they sure as HELL will make it quicker out of the hole. Basic physics my friend. Note: You said "quick" in your first post, not "fast".

Ok, Quick doesn't mean fast, well I'm sure when reading the whole post, ya got my meaning when i eluded to the 2wd would run like the dickens, but didn't see that... Anyways ya basically didn't give me any sign other than saying i'm out in left field,,, but that's Ok. Have driven down the 1/4 a few times over the past few decades.. At least i'm not driving that Diesel anymore.

I see you have a sense of humor even with those ya don't know... already feel like one of the guys

Well, not sure about the Tundra with the 6 speed. But I can assure you 2 equally equipped GM trucks with 4 speeds, one with 4.10's and one with 3.73's, the one with 4.10's will have a faster 1/4 ET every time (not sure about trap speed?). Probably one of the reason many guys are swapping gears from 3.xx's to 4.10s and sometimes even 4.55's.

I would agree that it depends on the motor and tranny setup, the gearing in the tranny and the Hp / Tq of the said motor, High torque engines would benefit from lower gearing, but your correct, not all Trucks or Cars benefit in the same way, or as expected. I did switch my Mustang to 4.10's from 3.08's cause it was a slug....

I'll bet a Tundra with say 3.42 gears and 2wd standard cab would run like the dickens if it could use 1st gear for more than rolling into the intersection to shift into 2nd, but its that low gearing that moves 10k lbs of WorkHorse weight.

I've got some thoughts:

1) What the heck is the Nissan "1/4 ton" stab all about? Payloads for the Titan and Tundra are VERY similar. In fact apples-to-apples Titans tend to have more payload capacity. http://autos.msn.com/research/compar...5046&v=t106490

2) I think you pay too much attention to the 4.30:1 rear end. Back in the day, when everyone and their mother ran 3 speed AT, a change in rear end ratios would make a huge and predictable result in acceleration, cruising/top speed, and pulling power. But now-a-days there are 4, 5, 6, 7, and 8 speed automatic transmissions. Way more important than just the rear end gear ratio, is how the overall gearing through the transmission works.

3) How many HD wannabe Titans have you seen? The Titan (like ALL 1/2 tons) have their cargo carrying and towing limits. How many racer Titans have you seen? I know of a few Titans on the internet that are pretty fast, as they race 1/8 mi or 1/4 mi tracks. They have to do it by trial and error.....the aftermarket is terrible compared to Ford, Dodge, and GM. Surprisingly..........considering the Titan is down 1 gear (5-speed at vs. Tundra 6-speed AT), and gives up 64 hp and 16 lb/ft of tq, the Titan hangs pretty damn well with the Tundras.

Your right and I guess there's more to a post than a thought, i can live with that.
