Supercharged Expedition.

[GTR John]

Just picked up a Supercharger kit from a Lightning. The guy was upgrading and sold his stock set up.

I have a 2003 EB. 187KM = 116M with about 80% hwy cruising mileage.

Engine and Tranny are feeling solid. Not gonna do any type of drag racing with this thing, just wanted the extra power and yeah, to show off as it's pretty damn cool to have a SCed XP.

Is there anything I should know before having this installed? What's the minimum to maximum HP output I can expect from this bolt on?

Thanks!

Do a search for "supercharger" on this site, and read up on what is needed to do the swap. You most likely have just the SC if he was upgrading, as he probably got a Kenny Bell or Whipple and kept everything else. You will need a midplate, intercooler, wiring harness, ECU, injectors, and a lot of little things to make it work properly.
I can't remember, but are the 2003 Expy's 2V or 3V heads? I think they are 2V, and if so it will work on your truck once you get everything needed.
Good luck and keep us updated with the progress.

Oh, I would keep it under 12 psi just to be safe. At 12 psi, you should be approaching 380-400 HP at the wheels depending on tune and supporting mods. 6# would yield about 310 with a stock Harley tune, and a stock Lightning tune for 8#'s would yield about 330-340.

Actually, he sold me the whole kit. I have all of the kit ready to put on. He was excited to sell me the kit because he is looking forward to seeing it done as he doesn't know or heard of anyone locally here that has supercharged an XP which of course makes me even more excited. lol

Thanks a lot for the link. Will keep you posted.

He must be going turbo to give you everything off the L for a total swap.

I'm not too mechanically inclined, but my tuner says I have everything I need for it to bolt right on and the guy that sold it to me said the same thing. I had my tuner look at the supercharger before picking it up to be sure.

Post some pics of what you have, and I can let you know. I had a Harley Davidson edition F150 that had the L drivetrain in it, so I have a good idea of what is needed. It may be a "bolt right up" install, but you will need to do a lot of work to make it run right with what you have as a base.
