did i mention 180K on the truck and drivetrain, 100K on engine

 

Oh, well hang in there..- She's not even broke in yet

 

forget the supercharger, it's time for a turbo, just get a good set up and enjoy it since you're towing alot a turbo is going to be your best route...

you're other option is to swap back to the 4.6 torque converter and hope the tranny survives but if you're still n/a than it should



as far as lack of power not here, I've got the 2 supercharged pickupsand the expy is about to get it as well but it runs pretty good on the autobahn here

 

What gears are in the truck? How tall are your tires? I'd bet the original tires were a lot shorter. What's the rpm at 60mph in OD?

I know switching from 245/75/16 to 265/75/16 killed my OD. It was ok on flat ground, but the slightest hill would make it downshift. On the plus side, it cut about 300 rpm at 65 mph in third gear, which worked out fine for pulling my car trailer.

 

I still do have the 4.6 torque converter....

and yea I know my tires are killing me, but I aint going back to a silly panzy look fo rthe truck.... it has 3.55's and tires are 285/75's...

 

I've got a 99 Expy with 137,000 on the clock, 3:73, and the 5.4 with a 3 in body lift and 33x12.50x16.5's and a flowmaster, and I've never had issues towing. I've hauled a 66 galixie500 and a motor cycle to PA from VA... then crossed over to Jersey and hauled a 80 Ford Bronco 4x4 from there to VA no issues.....as a matter of fact..the only thing slowing me was the wiggle in the trailer at around 65-70.. I cruise on the strights, and as soon as I see the hill aproach I shift OD off, and keep my speed. You have exhaust issues choking you up? I also pull @ 19-21 MPG in town at 45mph. I pull over 400 per tank alot of the time. I think something is wrong somewhere.

 

believe you me, I'd rather have a turbo than a blower, but I dont think there is any room for it

 

exhaust is pretty straight forward. Stock manifolds, all 4 stock cats and it dumps under rear passenger seats... Cats got alot of miles on em... think they are close to being clogged?

 

as for cruising, at around 72, the RPMs are turning at around 2100

 

Who is it that makes the turbo kit for these motors that places the turbo under the truck again? Maybe that would work for you......

 

damn! i wish my engine was that clean looking! nice job. im wondering if it would hurt anythign to start using that syntec blend now at 112,000 miles, i have been using castrol high mileage.

 

I saw an alternator he posted before, that Had been mud skiing. When he got through cleaning it, it looked like chrome.

 

you're thinking of STS

I believe the spyder kit is way better priced and is a front mount so no water sucking unless the truck gets sunk


I did alot of research after teh STS group buy went south and spyder has a greed to do a group buy if we can get 10 or trucks

 

That was the kids 4.2L. It took a little work getting that thing cleaned up-

 

lolz @ brew's analness.... wish I had the patience. . .


Under the truck turbo no worky.... this is a muddin truck
