off-road converter...?
Trying to find out what converter I should be running in my truck for a mix all around use...
75% DD in town, not much highway use at all unless getting parts or
heading to some trails, but I'm sure there will be some 'spirited driving' every few days.
15-20$ off road along trails, some hills, some sand and no doubt mud and muskeg (no its not the same as mud...)
BUT...this truck is built to double as a recovery unit!
That means yanking 7500lbs diesels sunk to the doors in mud with straps and/or literally dragging/towing busted vehicles all the way out of the bush.
5-10% Just screwing around light to light, donuts, whatever...
If this were a street/strip/DD car I could pick one, but seeing how its a heavy (6-6500lbs guessing) truck that needs to do a little of everything, I need ask the advise of others who've actually been there and done it, rather than "my buddy.."
The truck:
1980 K10
LQ4 - 500hp 80mm turbo kit is the plan right now, pretty conservative but no idea where it'll spool at...
Dana60 front
10.5" 14bolt rear - will be welded
TH400
NP205
6" suspension + 3" body lift
39.5"x18" wide TSL Boggers off road (bias ply, pretty light but still a large tire to fling around in the soup)
37"x14" tires for the pavement, may just run these full time...we'll see
From what I've found pouring through off-road sites and such, people are using 1800-2000 stalls mostly on rock crawlers and such, but haven't found anything quite like this combo.
Opinion's welcome, but I'm not made of money. :\

I've seen guys with 2500 stalls and 3500 and both this two wished they did different
2500 wished more the other wished less. Theses were 36 vs 39 tire size
IMO a tight stall would work best it seems your good with gears and tire combo for off-roading - I'd do 3k to 3200 tight being bigger converter size. To reduce heat but it if need ***** you can have your wheel spin - always run a bigger trans cooler 30k plus

Gears are 4.56 which on a 38" would be equal to 3.23's in a 30" tire I was told.
If I was doing a street vehicle for a combo of dd/strip, then I would certainly look in the 3200 range, but driving slow and easy with a larger stall would generate a ton of heat in the converter it's self.
Maybe ill have contact TCI or someone like that and pick their brain

I would say a tight high quality billet unit.
Yank 2800 10.5"
PI 2600 10.5"
Circle d same thing
The 2600 will be tight enough and tough enough to withstand the work, and loose enough with the right turbo set up to help a ton. Is it ideal for either situation? No.

That's why I might have to speak with a company direct to find setting that offers the best of both worlds...if there even is such a thing.
