You feathered it off the line and Tom let off the gas at the end because he was gaining too much speed. So both of you had some point in the pull that you weren't full throttle. Had Tom not let off he may have won by 30 mph instead of 20. Had you started a little better you may have cut it back to 20.

Having the extra gear does help off the line. I will give you that. But also, having 1400 lbs less helps a LOT too. In drag racing, every 100 lbs you take off in weight helps you go .1 seconds faster in a 1/4 mile. If you all just pulled for 1/4 of a mile then you would have been 1.4 seconds faster on nothing but weight alone. You all pulled for a mile though, so you had a huge advantage there. Add 1,400 lbs to your trailer to make the gcw even and Tom would have won by quite a bit more.

The 3v makes more peak hp because the heads flow better at higher rpms and it continues making power at 5-6k rpm where the 2v doesn't, but from 1-4k rpm they make the same power. The 3v would have helped, but I don't know if it would have been able to pick up 20 extra mph, especially in that short of a distance. I think your truck did a good job and I repped all of you all for putting the test together, so don't think I am talking bad about truck or anything like that.

 

If Monster-4 had done a 4L launch I think it would have been close.

 

Thanks Tom I'll have to go check that out.

I would GLADLY take on 1400 lbs for a Torqshift and a 4X4 launch. I had neither but if it makes you feel better I'll throw 1400 lbs in the bed next time and still do it in 4x2 and no power braking.

 

Launching in 4x2 and with no power braking could have easily been remedied right there on the spot. I know you didn't want to risk breaking something on the trailer or Tom's MIL's car, but if a man is willing to provide a trailer for a shootout, then I am going to assume that he is ok with me jerking it around.

To me, the TS wouldn't make a difference since your shootout was based on mph's and not time, but the weight would. The hill leaving my house is is a 15% grade, 1/4 mile long and pulling out from a stop sign mid hill. Same thing as your alls shootout, but shorter. Both of my trucks are manuals and I can reach the same speed by the same points whether I pull out in 1st or 2nd gear, although my time getting there varies. Pulling out in 2nd is a little slower getting started, but once I get rolling it doesn't matter what gear I pulled out in. I just know how much of a difference the weight can make on the mph's because one of the cars I haul weighs about 1,400 lbs more than another one and I can tell you which one is on the trailer without even looking.

 

Yeah, I was okay with it being jerked around. I'm pretty confident in the way it was tied down and I think everyone understood that. The only thing I wasn't willing to do was test braking distances. Nearly 20,000 lbs in a panic stop can be a real handful to control and it wasn't something we could risk on a public road.

I, for one, think the 5-speed tranny would have made a difference. Mike's truck kept accelerating in 2nd gear, but slowly. A shorter first gear would have allowed it to enter a shorter second much sooner and higher in the RPM range, which would have increased the power to the ground in that gear.

 

I agree completely. My F250 feels like a rocket compared to my Excursion.

I think that it is really cool that you guys put together a real world towing test. Hats off to all involved! (Next time make it 20,000)

 

I had the same thought, but Tom has the biggest trailer at 10K Gross weight.

Sooner or later I am gonna get in on one of these trailer tugging get to gathers.

 

I understand why you let off early, I was just referring to him not wanting to pull out pretty hard for fear of leaving the cargo on the road.

These mph numbers aren't exact, but they are close and I need to have something for comparisons sake. If I pull out in 1st(4.14 ratio) and run it to 3k rpm and then shift to 2nd, I am going to be doing 15 mph in 2nd gear at 2,000 rpm once I shift. If I pull out in 2nd(2.37 ratio) it takes me a hair longer time wise to get to 2,000 rpm, but once I get there I am still in 2nd gear doing 15 mph. I have the same speed, in the same gear, turning the same rpm. I have the exact same gear ratios in 2nd-5th no matter which gear I start out in though, so if I can hit 2nd gear it doesn't make a difference how I got there from then on out. I can see it being a difference on a tranny with different ratios in all the gears though.

If the ratios were drastically different then I could see the TS being a huge advantage, but first isn't really that much steeper in the TS(3.09 to 2.71) and the rest of the gears are really close(most are identical, with both having a 1.54, 1.0 and .71). It's like racing a car with a c4 in it and then putting a 2 speed powerglide in it. The c4 is a lot quicker off the line, but by a little past the 1/8 mile mark both have a 1.0 tranny ratio and both cross the 1/4 mile line at the same mph.

Look at it this way too. You had a .38 advantage in gearing off the line. That is the same difference between a 4.10 and 3.73(.37 to be exact). If you put a 4.10 gear in your truck and then put 1,400 lbs in the bed, do you think it would still out run your empty truck with a 3.73? Not saying you didn't have an advantage gearing wise, but I just don't think it was enough to offset the weight differential.

 

Very good point, It would top out the same either way, it would just get there faster with the TS.


500 pounds of the weight is the V10.
Is the other 900 just the 05-10 vs 99-04? Did they really beef it up that much in 05?

 

Exactly. All I am talking about though is the mph they topped out at, not how quickly they made the pull. The TS is going to feel a lot quicker off the line, but once both of them hit that 1.54 ratio tranny gear, they might as well have the same tranny. If you don't have the power to keep accelerating once you hit that gear, it doesn't matter how quickly you got it started off the line.

I live at the bottom of a valley and about all the roads getting out of my neighborhood are 15-25% grades, 1/4 mile long and from a dead stop, so I get to test my theory every single day lol.

 

YouTube - My Turbo V10 Excursion doing a Big smokey burnout.

This guy used to be a member, he talked about selling it and then just left FTE.

He put a turbo on it and burned it all way up to third gear.

Please take note of the fact all 10 spark plugs stayed in.

 

the last 5 seconds is the best part

 

Why is that?
It just shows weeds...
