The radix supercharger by Magnacharger is a good kit and is intercooled.I have had customers run it on the dyno and have made good hp and they also run the Whipple on the dyno and made 36 more hp than the Magnacharger.
Overall the Mgnacharger is a good kit and everyone That I have talked to with one is happy with it.
But if your after an intercooler supercharger it is a good way to go. Whipple is also making an intercooler upgrade that you will be able to add to existing kit. It's supposed to be ready sometime this summer.

The vehicles were 2 different H2's both with the Xtremeflow exhaust and cold air intake. The only tuning difference was thay the Whipple Supercharged one had the Power Flash to take out the torque management. What is the best price you have found on either unit I might be able to get you a good deal on either unit. Whipple will have the intercooler later that you can add on.

Why new valve springs? Heard about pinning the crank, and transmission upgrades...
What about the $200 extended drive-train warranty from Magnuson. What does it involve and is it worth it?

h2fan,
Thats great. I'm not sure why valve springs. Sure its not rockers? Also, make sure on the programming. The Magnacharger comes with a flash programmer for their supercharger.
TW,
The warranty is worth the $200.00 if there i a prolem you won't have to eat it.

should have the magnacharger on by july4 thinking of exhaust system -- they are pushing the valve spring because of boost. should be cool with some extra hp

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...

Remember, that with a supercharger you can get more HP and TORQUE out of the motor but also increase your fuel milage when towing. You will be using less throttle to do the same job as a n/a motor. You can get superchargers for less than $6800 no matter how conservative you are. There is always a good deal to be had.

Ken,
That would be like closing the door after the horse got out... A little too late for reports about poor towing ability. Before I bought the H2, word was that it would be good for towing.
Tearing apart brand new engines and transmissions to rebuild them isn't my idea of being sensible. Might as well install a supercharger and tear everything up before rebuilding it all? Plus, maybe if you don't use it for a drag racing machine, it might last for a while with stock engines and transmissions after being supercharged?
Or, maybe the "smart" thing to do is to do nothing...

But Ed, maybe we don't want to leave it stock. Maybe the smart thing to us would be having my H2 pump out more power then my Z06, hows 1000HP sound? Heh, just kidding but just remember, to each his own.
