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!
