6.2L & 6l80 Power Uprades

[ryaleon]

So I have done a fair amount of searching and there just isnt much info on the 08-09 H2 power train.

I am not after a drag truck by any means. I just want to add enough power so that I can spend a little more time in 6th gear and I want to avoid having to down shift so often going up hills.

What are my options? Gears? Supercharger? Any info is much appreciated.

ryaleon,
Not sure exactly what you are looking for since you are asking for power but also saying you dont want to down shift much.

To begin with these engine are in basic essence an iron block Corvette engine (LS1/LS2). So if you want some power, you can do all the simple mods that help Corvettes get power (intake, long tube headers, exhaust, cam....).

As for the tranny shifting, you can re-program it to help you out. But remember you have the 6 speed, which is what most want.... so you are already doing better with the shifts then most.

If you want better acceleration, then I would suggest dropping some gears in it, it could help you out also. Just remember to plan out your gears.
- I say that because if you plan to go with some larger diameter wheel/tires setup after you choose your gears you could end up going slower then you want. Like I am planning a mild 2-3 inch lift with some 37's at least then after that I will probably do at least 4.88s

Dont go running around dropping money trying to get what you want. The basics will get you what you want and all of this could be done fairly cheap. I can only see the gears costing you alot if you are unable to install them yourself and arent familiar with setting the backlash

I just don't want the Deuce to have to struggle so much going up hills at highway speeds. It always has to downshift to at least 4th and sometimes 3rd. Riding around town it has plenty of power. It's just the highway power that I feel is lacking.

I have 37x13.50s on it right now. So maybe the gearing is the answer.

pff try rockin the 4 speed like most of us have. Hell it will downshift from 2nd just going up a slight onramp.......

I had the 4 speed for a couple of years....definitely don't miss its highway power haha.

Does anyone make a true cold air intake for a deuce? Something that takes actual cool air in.
