Ed,
Yes, you have to weigh all the pro's and con's and decide if it's worth it for your situation.
Here in Pa, we have a lot of hills. All my driving is backroad and under 45mph. The H2 just struggles. Low power and TM keep it always looking for the right gear. I'm getting the SC to make it a bit easier on both me and the H2!
I'm not sure about your quote but if I had to take a stab at it...more power under the curve means just that..you are raising the HP and torque curve from the get go. Looking at a graph of HP and torque...you are putting "more" under the curve???

Mac,
I drop a friends H2 with the magnacharger about 6 weeks ago. Compared to mine...night and day. My stock 6.0 H2 still has it's tail between it's legs. I think, besides towing, the real difference is noticed with driving with the AC on at 65 mph and having to floor it to get ahead of the big rig that decided to merge into your lane when there isn't enough room to move sideways or hit the brakes without scraping the trailer.
Believe me, that 5 psi of boost makes a big difference (along with the reprogrammed computer).

Good luck with the Magnacharger, will be interested to see how well you like it!
Pushing the new valve springs "because" of boost? Of course it is because of BOOST. That is what a supercharger does is boost the air/fuel mix... But, WHY does supercharging the engine require new (stronger?) valve springs --- is my question.
I would imagine that completely rebuilding the engine wouldn't hurt either? Stronger valves, rods, pistons, cranks, etc... Rebuilt, beefier transmission too? But tearing apart a brand new engine to beef it up seems just a little bit on the extreme side of sensible to my conservative values.  As it is, $7,000 for the extra HP seems a wee bit expensive?
Cruising in my H2 at 75mph on the interstate, my tach reads about 2,250rpm when not pulling any trailers. Would a supercharger really be doing anything or just loafing along? I know, if I punch it and accelerate the supercharger will really make a big difference. But I rarely ever need to do that...
But, pulling a travel trailer? That would be quite helpful then? But, say I use my H2 10 days a trip, twice a year, for three years. Total of 60 days of towing. The supercharger cost would work out to average more than a hundred bucks a day for each days use when towing... Over a thousand bucks per travel trailer trip?
I can pull a travel trailer without a supercharger... but not as easily. Do people think it is worth that much money to be able to jerk that travel trailer along faster? I didn't include the cost of premium fuel over regular fuel either. About 13% more in fuel costs?
The more I think about it, the more I think I will just drive in the right-hand (slow poke) lane and take a couple hours longer each day to get to wherever I am going. Maybe spend the 7 grand for a nicer travel trailer instead of a supercharger?
Decisions, decisions!

The only things in the 6.0 that are strong enough over time with a SC are the crank and rods. Better replace or rebuild everything else w/ heavy duty parts. Especially the trans.
I do not trailer for long distances, but I believe there have been posts about the poor towing ability of the H2. This is primarily due to wheelbase and height. Check it out...

I don't think that by just adding a supercharger you need to "rebuild the whole engine". There are plenty of SC's on stock engines that last a LONG time stock.
Just drive sensible and don't try to "spin all four tires"...
I'm having a whipple installed and everyone told me there was no need to rebuild or change anything.

Good question.
I'll admit that I don't know much about superchargers (and that is an overstatement) but I think I can pretty much guess that you don't really "need" a supercharger, Mac. If while climbing your "really steep hill" everyday, your H2 is "full of power" --- you would probably not "appreciate" the extra horsepower and torque available to you from a supercharger.
But, I'll bet that if you check around, you should be able to find someone with a supercharged H2 for you to ride in?

Ed,
That's exactly why I did it. It makes it so much more fun and enjoyable to drive!
