That 350 looks so big next to the rx7 heh.
It doesn't look like that was a good start off to me, the 7 sorta jumped ahead and it looked like he stopped to sniff some roses.... and what the hell is all that black smoke about coming from the 350?

[bruce95fmla]

hahaha, that was hilarious.
It sounds like a Turbo desiel... looks like that could explain the smoke.

Thats definetly a diesel and the reason for the smoke, but with runs like that, i don't see the fuel savings adding up

Those Ford diesel trucks will '**** n git'. We have a Limited edition Excursion at work that we tow an enclosed trailor with. Even under full load, the truck has NO problem accelerating.

yeah we have an f30 super duley at work, v10 turbo diesel, we pull or 22 foot coastguard boat around in it all the time, and it has no problems geting up and going, and the boat weighs like 7000 pounds plus out trailer, so figure that out.

Let's see.

F350 Super Duty dually
The V-10 is a gas engine.
The turbodiesel (Powerstroke) is a V-8.

0-60 with that set-up (13k GCW) is probably about 20 seconds. It just feels fast, because your brain thinks it should be slow with that much weight.

And the best of the 7.3L Powerstrokes made 520 lb.ft. of torque, and most of it made it to the rear wheels (conservatively rated). The latest 6.0L Powerstrokes are rated at 560 lb.ft., and are again conservatively rated, and get an extra gear in the automatic.

Oh, and the reason for the black smoke is to keep the engine from melting. When you ask for that kind of power out of a diesel, the way you keep it together is to dump in more fuel than you can burn (same thing you do with a gas turbo), and when diesel doesn't burn completely, you get soot.

That truck was probably pushing 40psi of boost to get that kind of acceleration. If you saw the one in the latest Car and Driver (the GTO Silver State story), they were making 700hp and 1300lb.ft., although they likely couldn't do that for long (in other words, even though that's enough power to move an 80k lbs semi, the engine couldn't do it continuously).

so you're saying a diesel HAS to run rich to keep it from "pinging"?

HaHaHaHa. :rofl: You so funny.

Considering that "pinging" is essentially how a diesel works, that's pretty funny.
