About to test drive the dually

I finally have everything buttoned up after putting the transmission back in the dually. I even have the colossal oil spill cleaned up where I started it with the turbo off to hear what it sounds like through the open manifold!

(note to self: Turbos have OIL SUPPLY HOSES, hoses that don't cease supplying oil just because there does not happen to be a turbo at the other end any longer.)

The freakin lube for this transmission cost me $84 for 4 quarts, and it looks like I need another to completely fill it! What a ripoff. Oh well, at least I get to drive a 12v again. I've gotten used to driving the common rail '06 we have, but nothing is like a 12v. INSTANT throttle response with those.
 
Well, it runs fine. I had to loosen one of the intercooler boots to get the turbo hooked back up, and I forgot to tighten that boot. 45 psi of boost will find a loose boot rather quickly. So, after tightening it back up, I took it out again and immediately blew it off again. At least, I assume it's the same one, and that I did not get it back on correctly. It's kinda hard to see when it's getting dark. No biggie-the truck is driveable without boost, it's just slow.
 
Retightened it, this time correctly. It now holds the 45 pounds of boost. Traffic behind you recedes rapidly when you apply 900+ ft/lbs to the situation.
 
If I ease into it, it's not that bad. If I just smack it then it can black out much of an intersection. Spoolup seems to be a little better after the transmission rebuild, which leads me to believe that I may have had a boost leak prior to the rebuild that got fixed when I reinstalled the turbo. Or it may just be that it's cooler outside now, and cooler air is denser than warmer air. Either way, it'll get moving quick.
 
Ok, here are the pics:

The first 5 are of me. The lady in the van won-for the 4th or 5th time in a row. I should have speed-shifted into 4th. I did it in 3rd, because I knew I could run it in that gear without having to shift. I revved it against the limiter and just dumped the clutch. Instant wheelspin w/o a problem.

(Warning: Don't try a 3rd gear rev limiter clutch dump with a stock or wimpy aftermarket clutch. You'll get smoke alright, but it'll be of the stinky variety and probably won't be coming from the tires.)
 
Nice lookin truck...too bad there's all that smoke in the way :doh: you really can't get a good look at it :D
 
It's actually kinda ugly in person. It has 270k on it, and a 17 year old boy was driving it for a while. His dad took it away from him when he hit a trashcan and put a scrape up the passenger side, breaking a hole in that fender flare. I just recently replaced that fender flare with a red one off another bed I had lying around. The main thing to me is the power it makes, and the fact that it does not look at all like it would be capable of doing what it is. The ET is deceptive, in that it's artificially slow because the truck is hobbled by having to granny shift the 5 speed. The 98 mph trap speed is really more indicative of what it's like to drive it. I want to take it to a dyno that's not as pessimistic as our local one is, and see what that says. I quote the figures from the local dyno because that's all I have, but I know full well that the particular dyno in question is low, REALLY low. Like maybe 12% low in many cases. It says some things that are basically mathematically impossible, like a 3100 lb car running 138 mph in the 1/4 with only 546 rear wheel hp. Bunch of baloney, like my buddy's 3700 lb buick grand national running 142 mph with 670 hp. Yeah, sure.

Anyway, I'm off on a tangent. There's a particular dyno that mainly caters to supercharged mustang cobras and ls1 gm's that I want to go to. Their torque record for that dyno is 900-something ft/lbs. I wanna drive down there (180 miles each way), smack that record down in the ugly dually, and drive away. Sometimes gas burners need to be reminded of the difference between torque and TORQUE.
