I don't know if the H3 has it, but the H2 has a MPH readout..........Just wondering how it would work.

 

someone is making money on crap

 

I've been contemplating some things like this. Airraid, blah blah blah. The local airraid dealer is a hummer guy (on his 2nd H2) and his sales-dude stated taht they got 8 initially with the first H2, and after breakin, Airraid intake, throttle spacer, a computer chip, and some exhaust, got 16. The sales speech was "see, car makers always go with the smallest cheapest possible, barely adequate stuff"

But here's the thing - the H2 already has a massive intake system that's certainly not the cheapest barely adequate anything, and more horsies than any incarnation of this engine except the Escalade. It has much more power than my pickup, which has the same engine, and mostly NOBODY HAS ANY DATA ON THIS STUFF, especially for mileage. K&N has an informal-looking dyno graph showing a faint horsepower increase at like 4500 rpm, and that's about it.

If something works, the people that make it generally test it in fairly short order in as formal of a way as possible. If it works, you've nothing to lose and everything to gain.

Now, take a 30 year old pickup - that could probably really benefit from this sort of thing. Take a brand new H2... i don't know. The cold air intakes advertise plastic boxes and have seals to go against the hood... The H2s intake box is plastic, and huge, and vents only to the outside of the engine compartment. I can't see how it doesn't have a colder air intake than the aftermarket stuff.

So while i'd like another MPG or 2, i think i'm leaving well enough alone and running my engine stock.

 

is it possilbe to disable fuel and spark plug on one cylinder for fuel economy?? isn't 6.0 liters a bit to much engine? (the truck ways 1000 pds more than a tahoe)

 

98 pds per wheel. if i get a hummer i'm gonna look into getting lighter rims with the same tires. (i read that gas is spent mostly on accelerating)

 

i am having difficulty finding weight of original H2 rims??

 

That is basically what Dodge did with thier Hemi. Under cruise or very light acceleration the PCM shuts down 4 of the eight cylinders, effectively making it a 4 cylinder engine. The exahust valve stays open a little bit so the piston isn't meeting resistance from compression. As soon as you need power, the PCM kicks those other cylinders back in and away you go. The transition from 8 to 4 and back is almost un-noticeable.

 

i got the weight for the stock 315 /70R17 tires are 65.05 pds. so the rim must weigh 33 pds, sounds about right. there are rims of that size that weigh only 22 pds. but i guessing that bigger rims would lower the overall weight (something i learned from mountain biking).

 

It would be my guess that a bigger diameter rim would weigh more because there is more metal. The metal weighs more then the rubber, and they both weigh more then the air inside.

and by the way what size motor you have on your mounting bike
