RE: just a little more power

Not anymore. Most HD pickup trucks only have one gear option these days. Not for gas trucks. Dodge offers 2 options, Ford offers 3. Gm is the only one that does not have an option. They haven't for a while iirc. There are only 3 major manufactures of consumer HD trucks, and 2 of those offer different gear options, with increased tow ratings for deeper gears, for the gas trucks.

RE: just a little more power

I'm not sure why people think the rear gear ratio only changes rpm/mph. It increases torque multiplication to the rear wheels. It will tow more easily in all gears. It may allow towing one gear higher than usual If the truck is in fact a 3.73 truck, it will make a difference going to 4.30's. Ford didn't offer that option for fun. Yes, it will increase cruise RPM in 6th by 2-300 rpm. Might loose 1mpg unloaded. But as Fish stated you may gain mpg towing. You know WHY it "tow more easily in all gears?" Because the engine is running at a higher RPM at all speeds! The engine produces more HP at higher RPMs, up to the peak of the power curve. People think "gear ratio only changes rpm/mph" because that is precisely what it does. If you were doing 60MPH at 2000RPM with stock 3.73 gears, you will need to rev the engine to 2305RPM to maintain 60MPH with 4.30 gears, or you will only be doing 52MPH at 2000RPM. You still have torque multiplication happening. For easy math, lets say you have an engine with a nice flat torque curve. 100ft lbs at both 2000 and 2300rpm. Running in direct (1:1), also to make the math easier. 100ft lbs x 1 x 3.73 = 373 ft lbs 100 ft lbs x 1 x 4.30 = 430 ft lbs The main benefit is not that it puts you at a different rpm closer to the torque peak...it is that you increase the torque multiplication in every gear.

RE: F150 Lightning Road Trip & Ike Gauntlet Pull

Well this certainly descended into a pissing match of total silliness lol. Thanks for the laughs. Right? It towed the trailer very well. Are there range issues. Yes Is anyone surprised by that. No Can you make it work if you change your driving habits. Probably Does it have impressive power and is unaffected by elevation. Yes No one is surprised by that either. It did a great job towing the IKE and didn't break down on the road trip. But it's not for everyone. No big surprise there. ICE vehicles will be around for a while yet for heavy work.

OP did say "seat as many grandchildren as possible"...not that he NEEDED to fit all 10 kids all the time. Also, they haven't chimed in since page 2. :)

RE: Hemi to be replaced by inline six?

If anybody want's to learn why, this is a great video to learn from. If you just want to know about torque, start at the 3 minute mark and learn about long and short stroke and what it "doesn't do to engines." Don't like videos? Fine. Lets talk about actual diesel engines. Engine #1. 2006 LBZ 6.6 Duramax. (Why this engine?) Because I own it and know about it. Engine #2. 2006 Ram Cummins 5.9. Engine #1 according to the internet the Durmax has a bore of 4.055 and a stroke of 3.90. (almost a square engine) Engine #2 according to the internet the Cummins has a bore of 4.02 and a stroke of 4.72. According to a lot of people on here the Cummins should kill my engine in torque because of the long rod. Here are the dyno numbers: 2006 Duramax puts out 650 ft/lbs of torque. 2006 Cummins puts out 610 ft/lbs of torque. So much for the long stroke putting out more torque. I can hear the fan bois all ready saying that's not fair!! Your Dirty Max is a waaaaaay bigger engine!!! Fine, more facts: 2008 Duramax 6.6 L vs 2008 6.7 Cummins: 2008 Duramax 6.6 L = 650 ft/lbs of torque. 2008 Cummins 6.7 L = 650 ft/lbs of torque. Well would you look at that? Same exact torque even though the Cummins has a waaaay longer stroke. :B Engine Masters did a TV show a few months back about rod length. Everybody on the show (me too) thought the long rod engine was going to put out more torque. WRONG!! They were the same within dyno measurements. Link to Engine Masters rod article. A few things...your example engines are all turbocharged. That throws everything out the window since the boost levels and other tuning parameters can easily change the power levels. And longer rods to not always mean longer stroke, as in that engine masters comparison. However, I do believe that in naturally aspirated engines, displacement is what increases torque in an apples to apples comparison. It just so happens that usually the easiest way for a manufacture to add displacement is to increase the stroke. If you have two engines that are an I6 and a v8, with the same displacement, the I6 will not inherently make more torque or be a "stump puller" just due to its inline architecture. Engines are air pumps. The only ways to pump more air is to increase flow efficiency, increase size, or increase air density (boost or elevation changes for example).

RE: Great cooling system on them there SilverAdos!

Admit it, if they'd changed the oil you'd be complaining about them performing services you didn't ask for and charging you. But when they did the lifter service on mine they had to drain the oil to look for bits in the bottom end. So I got a fresh oil and filter as part of the service. You sure they didn't do that for you? The guy who was suppose to reset the oil life monitor was probably the same guy who left the cap off the coolant reservoir. :D

RE: Place your bets now!

Yes I'm hard on transmissions. Especially if first gear is really tall like the th400. Tallest ever on market. Load one down in my case 15-20k gcw, try to go up a 15-20% grade, stop and go traffic all day long, even with 4.10 gears in pumpkins. Thing get overheated really fast, stalling out was not uncommon. Yes I did have an aftermarket big cooler. Helped a little. I have more get up and go with my 6 sp auto, 3.42 gears and a V6 in my current 1500 than I did with the 88/89 BB 3500's I had. I would've had to drop to at least a 4.88 to not have as many issues as I did. Driving on a freeway is different than here in Puget sound local roads. Saw an article the other day, steepestroadin Seattle proper is 26.3%. Those grades wreck havoc with an improperly speed drive train. Marty This is why GM put the th475 in motorhomes and other applications that would see extended pulling in lower gears with a lot of weight. Same tall ratios, but straight cut gears to get rid of the thrust loads in the gear sets, for extended pulls with a lot of load and throttle opening.

RE: Quality Hybrid Manufacturers

Looks like Starcraft dropped all their hybrid models too.

RE: GM's New LT6 Engine

If you are in the market for that kind of car, its a heck of deal too. I always thought the z06 was a lot of car for the money. But the new c8 is impressive. I don't like the center console, but the rest is awesome.

RE: Need help - Weight distribution hitch installation pics

There is no adjustment you can do to get rid of the push from getting passed or getting hit by a crosswind. From my experience, the bigger the speed difference between you and the person passing you, the more you will feel it. A push is not the same a sway. I think a lot of people get it confused. I'm not sure how to describe it but real sway but its no fun. I'm sure someone here has a great description.

RE: SUV for pulling hybrid

We've been towing our Hybrid for the past 6 years with late 90's Suburbans. Starcraft 239TBS, about as big as a hybrid gets. 6500lbs GVW. First a 1500, now moved up to a 2500 version. 1500 did fine, but there were some hills that would slow us down to 45 or so. Don't forget, this is with trucks that are almost 25 years old as well. My FIL tows the same sized hard side with a Ecoboost Ford Expedition, and used an 04 Tahoe before that. He also had a hybrid (Roo 233) he towed with the Tahoe for a few years. If you make sure it has a real tow package, you should be fine. 2500/3500 Passenger vans are also a great fit if you don't want 4wd. I've seen a few family's using the Nissan NV's to tow campers in our travels.

RE: Loss of power when driving

Well, I was able to get someone with a Code reader to go over and check it for me. It was creating 2 codes - The first was P0327 and the second was P0332. According to what I have looked up on them, one is Knock Sensor 2, circuit low bank 2 The other code was - Knock sensor 1, circuit low bank 1 I'm still suspecting a fuel filter which is nearly impossible to find with an adapter kit to take it from 3 ports down to just 2. I have tried to order from numerous places and they all seemed to be back ordered. I won't be back at the RV until around Oct at the earliest. If not then, December will be my next attempt. I would check the wiring for the knock sensors. It may be pulling timing way back if the knock sensors are not reading correctly, as a failsafe. that would make it loose a bunch of power and it could backfire when you get on it, as you reported. But it is odd for them both to fail at once so I would inspect the wiring harness to the sensors. I'm not sure why you are suspecting the fuel filter when the computer is reporting a problem reading both knock sensors. Not that it hurts to replace the fuel filter.

RE: Towing with a 2022 Ford F250 7.3L

I would not pay extra just for navigation on any vehicle that comes with CarPlay or whatever the Android version is. You can also play music from your phone and do handsfree calling. Lots of functionality there. I have an older version retrofitted into my truck and love it. Just requires a cable to my phone instead of bluetooth.

RE: Towing with 2004 Lincoln Aviator

Something else....the 4 valve 4.6 is not a low rpm engine. So it will seem like it is working harder to pull, as most of the power is higher in the rpm range. It should do the job but it will take a little RPM on the hills to maintain speed.
