[Hunner]

Ok got the mock up or protype today. Just wanted to post that an AirMax intake for a Colorado truck will not work on our H3 because of the air conditioner hose over there will not let it line up. So they made me one. They pulled it off to make a cad drawing and have one laser cut and powder coated. Im going back Wed to put the prototype on and drive it for a few days to see if all works well.
The throttle body spacer by them works on the H3 and the stock air will all go back on. The True Flow would work as well.
SOPD will have to do for comparison to a Colorado because the dyno is not for four wheel drive. I guess GM either has one or matamatically figured HP and torque.
For now we used the bellows coupler from the stock setup. We increased the tube size over the True Flow pipe from 3" to 3 1/2" same size all the way from throttle body to filter. We were making this up as we went along and decided with the full volume pipe we could leave the bellows to allow for engine torque and movement especially in low range and uneven terrain. Just a thought. I know it does not look as smoothe but they wanted to try this for now. More later, I have started a mpg log but I think the first tank is going to be poor, I can not keep from WOT to hear and feel it! Im still running no Muffler and straight pipe where it was but left the cat, oval pipe and resonator for now.
I still have mixed feelings about the open filter off-road but after all the engine is going to suck in whats out there. I now have the options for either. Water is my main concern about the wide open exposed filter. I guess in monsoon season I can swap.
