At the risk of beating a dead horse........ I've been reading the many posts regarding the HAI, CAI, midpipe, resonator, etc. modifications, and the argument seems to center largely around "how much power" and less about where the power is.

My .02 worth, if you take the midpipe out of the CAI vs. HAI vs. hybrid equation, you are left with what to do on the input end of the maf. I think power losses with a pop charger vs. a CAI are less about the warm air and more about the length of intake entering the maf.

This is my unscientific explanation: If the input side of a motor is the same as the output, (and my experience has been that too little restriction can be a bad thing, ie. exhaust break or open headers), the same properties must apply to the input to the maf. The pop charger, while good for breathing on the top end, is just a wide open hole with little vacuum supplied. Seems like the best compromise is a slightly longer input tube into the maf (less than a full blown CAI, which reduces top end) with a good breathing filter on the end, K&N or Monsterflow.

I'm not trying to re-invent the wheel, but I seem to have lost a bit of low end by just placing my Monsterflow filter at the end of the maf. Could I punch holes in my stock box and run a panel K&N?...sure. But since I have the monster, I'd like to use it.. I think these 2 setups would be pretty similar, but you might get better top end flow with the better filter.

Has anyone explored this? My Stillen popcharger for a truck had a fiberglass box that helped isolate the hot air from the filter. Has anyone made one of these yet?

 

So...I guess this horse is dead, eh?

 

there have been a few members that hacked up their stock air box from the top and use it as a heat shield for their hai. i dont really want to rip up the only stock air box i have since im still in warranty but i was looking at doing something like this it only costs a few bucks and should keep some heat from my berk/frankencar intake. if it does not work then no big loss. when the heat comes back late spring next year, i plan on getting a spare box and running a ported box with a k&n panel to help the low end loss.
