Josh I've looked all day and can't find one single 5.4l engine data sheet that specs the 5.4l peaking torque @2500 rpms. They all say 3750 or 3800 rpm. I got the 7.3l's peak torque from the international powerstroke website. Either they misquoted their own spec or that spec isn't for your year.
I know the toque converter isn't locked 100% of the time, but it is when it counts. Or I'll say it should.

Having driven the same truck, same engine, same gearing with both an auto and a manual with the low 1st, there is absolutely no comparison to them.

Same here. My wife didn't pick out my truck, my wife doesn't pay for my truck and my wife doesn't drive my truck. She picked the Suburban that has been a thorn in my side (and a pain in my wallet) since we got it and she can drive that all she wants.

I've been away from FTE the past month. Just to busy to keep up. I spent the past few hours getting caught up on this thread. I found a few things to comment on.
The same driver (Tom a.k.a Crazy001) drove all 4 trucks, the same trailer was used, the tests were done on the same day within a several hour window, the front of the trucks were lined up with the same sign post on the same road, all runs were video taped so time can be extrapolated from that. I agree the test were by no means scientific but inaccurate they were not.
The first two runs were with stock tune. The last two were with 93 tune. I like the V10 but I have no problem saying that there is no way a tune can make up the HP difference in my second oldest generation (PI, 2v) V10 over a 6.0 PSD.

Of course I'm still more of a diesel guy; I'm on my second PSD and never have owned a V10. Almost did, but I really got used to the way my 6.4L towed my trailer and was afraid I wouldn't be as happy with a V10.

Crazy001 ( Tom) admitted that he did not run the 7.3L as hard as he would have like too, in fear of breaking the truck. (it was smoking at the end).... How can you call that a fair race, or an accurate result? The only part that was accurate was the first hill, thats it. both trucks WOT

next time we run the test hopefully there will be same generation trucks running to their potential. There is no reason you should not have been able to run a stock 7.3 WOT that entire run. Like I told Bill also would be interesting to run a Dyno on the same generation of trucks to get an idea of RWHP also before doing the tests.

Mike's right, we did everything reasonable to ensure consistent results. But I have to admit that I got nervous driving someone else's truck with 200,000 miles on it as hard as we were. I did not know the owner of the truck very well, and I did NOT want to break his truck, so when I saw signs that something wasn't right I got a bit nervous.
I'm coming back to Ohio at the end of the month, maybe we can get another one of these set up!

A tune should easily provide 15 hp. The point of that post is to refute the argument that regardless of torque the truck with the most horsepower wins. Especially when the 6.0 powered up that hill compared to the v10.
I know, bill is gonna talk about the tranny and I am gonna say again that there are more factors than hp, thanks for agreeing with me, and we start the circle of life again. Hahaha

IT'S FUN. That's probably the biggest reason we've done it three times so far! All three times we've had my '08, Mike's '00, and my white trailer, with various other players who find the time.
It's not often I can meet up with other guys who have the same enthusiasm for trucks as I do. Most of my friends just think I'm strange...

You must not get it.

Just noticed you are from WI. Central, north, south? I'd be willing to come out to a meet as well with my bone stock 03 7.3 for some fun and chat! I too can't get enough of vehicle chat, my wife hates that.
