So there was a tune on the V-10? If so, where is the fair comparison?

I thought this was stock to stock.

 

Not all of the diesels were stock, the trucks weren't close to the same years, and there were a lot of other variations. They were pulling for fun.

 

On a 2-valve V10, there's not a huge difference between "stock" and "tuned" like there is with a diesel. However, there are shift changes made by Mike's 5-star tune that helps in the torque-converter lockup for instance.

If the V10 had a blower or a turbo on it, it might not be a "fair" comparison though

 

Let's not forget that my truck is 5 to 11 model years older than the other trucks. What would you say if I compared mine to a 1989 truck?

 

Well, based off the sounds coming through the videos, your truck sounded much cooler than any of the rest! I'm a diesel fan, but I really like the sound of a good running engine through a good performance exhaust!

If you were to compare your truck to a 460 powered 1989 truck with headers and turbo mufflers, both would sound great!!!

 

Your truck performed pretty well actually! It was quite a bit slower out the gate, but still did well.

Honestly, though, I wish we could get all these trucks on a good 6% grade for 8 miles or whatever and see which one performs better. I know that type of test is harder, to most owners, it is more relevant.

 

I know of an excellant 7% grade coming out of Western MD on I68. It is a few miles long. Best I can do up that one this summer was 55 at the top of the hill. That was with my 5er coming in at 15K for that trip.

I think it is about 3 miles long...or at least it felt that way.

 

It's nice to see the comparison between truck, engine, and tranny choices. Although, too bad a 7.3L truck couldn't have made the trip. =(....

 

Actually, to MOST owners, that test would be IRrelevant. That's basically a pull of 2500+ feet elevation all in one pull. Those conditions exist in about .1% of total driving by people using diesels in 3/4-ton and 1-ton trucks, not to mention gassers.

It would be FUN to compare them in a pull like that, however

 

I don't know if I am in only .1%, but whenever I drive I have long grades.
Going South Grapevine Grade 7 miles at 6%, going East-North the Truckee Grade is like 24 miles with variable grades, but 6% seems to be pretty common.
Going East-South the grade past Bakersfield is like 11 miles and than have several more on I-15 where holding gas pedal on the floor for 1/2 hr is pretty common.
Going North -Shasta grade is well known as well.
Than I love the I-80 grade east of Salt Lake City where going down on neutral for 10 miles you have to brake hard to keep it below 80 mph.

 

Yeah, but all these trucks can pull any load over flat ground just the same. Going up a 11% grade from a standstill is less likely than pulling a big hill. If all I did was drive on flat ground, I would still own my Chevy 6.0 gas engine... So yes pulling hills is than 5% of driving, but when you have to pull 4 similar hills in a 9 hour period, you might change your mind.

 

Thanks! Tom, whom was driving my truck in the video, actually keep the window down so he could listen to the V10 belt out it's song the whole way up the hill. My exhaust mods are pretty mild. I have Ford Racing headers, and a cat-back Flowmaster system with an FM70 muffler. Everything else is stock and original as far I know/can tell.

Thanks! The real kicker is if I had the proper gearing the launch would have been much better. Not only am I running 3.73's but I'm running 33" tires (stock is 31") so I'm probably in the 3.5 to 3.6 range for gearing (to lazy to do the actual math).What really strikes me about these videos is that my old V10 that is 11 years a two gears behind the 6.7s was only 6-8MPH slower at the top. Yeah she wheezed out of the gate but once the RPMs were able to come up it took off.

I have no doubt as the altitude got higher I would be way down on power. I really wouldn't be afraid to let it rip and sing all the way up the mountain however. Might be annoying (depends on your viewpoint) and might not be the fastest way up and over but I think the trusty old V10 would do it, repeatably. Once again gearing would play a big role. If I was out west and climb the mountains out there a lot I would either have a PSD or invest in gearing to make up for some of the lost power at higher altitudes.

Really though I can't say enough good things about the 6.0, 6.4 and the 6.7. I love the diesel power delivery and if my needs were different and my pocket book was bigger I won't hesitate to own any of them. I'm not a gas or diesel guy but I am a Super Duty guy.

 

Plus all the other trucks had a lower first gear than you. 2.71 vs 3.09 or 3.97?

By the way, has your speedometer been adjusted to account for the larger tires?

 

If it hasn't, then his speed would have been better than what the speedometer was showing.

 

I-77 from the NC line north into VA is a pretty good grade. There are varied opinions of the percent but they go from 4.5%-7% and it's about a 7 mile grade. It would make for a good run pulling that weight. You can get on at Exit 1 near the Love's Truckstop and go all the way to exit 8 at the top of the grade. Just sayin'....

Anybody wants to come down here and pull it, we could set something up. The grade starts from the time you hit I-77 right off the entrance ramp and continues all the way to about a 1/2 mile south of exit 8.
