I'm not specifically interested in charging my truck right now. I appreciate the info on where to go when I am ready though. I'm mainly interested in understanding the thermodynamics and physics behind chargers, and also the mechanics. Basically when the time does come, I'll be fully comprehensive to what is happening, haha.

The reason I'm hesitant to even consider charging the truck right now is due to the fact the truck has 190K miles on the original motor and transmission. The extra stress from a charger would only decrease the time she has left on the original parts, haha. I'm in college and need her to last at least until I graduate!

 

I know that we hear about these engines going strong at 250k, 300k, but at 190k I don't think I would add boost with the increased cylinder pressure, open to debate as always.

You might enjoy Corky Bell's Supercharged...cheaper on Amazon, no doubt.

Whether a taken care or 4.6 or a 5.4 what would you say would be a safe threashold for milage for adding a modest 8 lbs. of boost. as a starting point. Ive got about 98 k.

 

I'm not sure, but I would go 0 psi at 190k and 8 psi at 98k. Good fuel upgrades and good tuning FTW.

 

I would throw boost on a 200k mile engine.. Hell I've done it before!

 

I boosted mine at 174k. Its at 192k now, and still strong. (knock on wood) . My trans was what didnt like the supercharger.

 

Same here. Tranny was gone in no time. These motors are solid. If its been taken care of it 200k is nothing. These aren't your 302's of yesterday. Much tighter tolerances on these.

 

My truck came with a 3:55 open rear end which sucked lol. I put an Eaton limited slip in it about 9 years ago and it has held up fantastic. I like it a lot for it's street manners. Drives like stock, nice and smooth in the turns. But get on it in the turns, or off the line going straight, and it locks up hard until you get back out of the gas.

I've also heard nothing but good things from the Lightning guys about the Detroit TrueTrac. I would consider this unit as well if I had to do it over again.

I wouldn't even consider a locker for a street vehicle unless it sees the majority of time off road or at the strip. In all other cases a good limited slip will be more than sufficient and have a lot better road manners.
