Cold Air Intakes
Nice work NV - Im going to order the gauge also. Man does that get hot. Imagine in a 100 degree day. Under hood temps would be over 150 easy, if not more. Gotta admit, that is pretty severe.
I was searching some air properties and found that at 70 degrees the air volume is 1-1 and for every 10 degree drop or rise in temperature will adjust that same amount of air in a cubed meter by 2%. The difference between 100 and 80 degree air is a 4% increase in density and a 4% increase in volume once detonated, which should generate a 4% increase in output power(Comparably) and use approx 4% more gas to equal stoich.
The colder air would result in a much better performing system, with lower underhood and engine temps. I presume also a decrease in part failures due to removing the extreme operating temp.
Hammer, I wonder??? Remeber when those little diode tricks were everywhere for tricking the IAT into believing it had cooler air, well what if we kept the IAT outside of the intake. I know we would be running lean with less fuel being -used. Since A/F should be at 14.7, but power output is highest at 12.7 to 13.3. Hmm more interesting.
This would still acheive the same benefits but without the extra fuel being used. It would also cut the power gain to less than what was acheivable, but an increase would still be evident

Nermind, bitches......Haha. Got the 3865 Superchip. Loving life now, yeah.
NV, I also read an average temp of 20 - 22 IAT above exterior temps. Lets assume this is a good base line. I am still working on the Real CAI system, since our last talk. I am waiting on a replacement filter element. It will be here tomorrow. Once it is all done, I will post the affects.
Reiteration - Best modification ever - Superchips 3865, especially the superchips tranny tune, been turdless ever since

Alright more to this. So here is the intake, it looks like you just remove the stock cover on the air box, and still use the lower stock air box.

So, that means it doesnt have a filter down in the bottom front of the truck. like guys who run open filters on a DIY setup.
Wondering if I should just build my own now or go with this thing.
Also wondering since it doesn't come with the MIT tube, if I could build my own out of PVC? What would need to be drilled in to it? Crank vent and air sensor?

Technically yes. BUT, the filter assmbly you have mounts to existing holes in one place. The MIT is perfectly shaped to connect from the filter to the Throttle Body. 4" PVC pipe will only allow you make 90 or 45 degree bends. Based on how the MIT is shaped, you will never be able to duplicate that shape with PVC pipe. The curves are unique. The only way it might be possible would be to drill new mounting holes for the filter bracket but even still, you might have clearence issues. I know it costs more then PVC, but buying the MIT will be much easier in the long run.
I'm considering removing the stock filter box and hemi hat completely and then buying a K&N and piping it down to where the air box would have sat. This likely would be less expensive and floor a bit more cool air I would think? Plus I can go right to the Throttle body.
Has anyone ever had concerns with the filters sucking up more dust since they are effectively wide open and not in a box?

Hey, Hammer, I thought you sold your truck on April 1st this year ... or was it last year ... I forgot ... oh ... I get it ...
j/k
All joking aside, I've looked into this recently myself. Having plunged into getting a SuperChips tuner of which STILL doesn't work - damn truck - working on cleaning up the contacts to the PDC and see where that takes me. It just HAS to be a bad connection.
So anyway, I bought a "CAI" but the tube extends a little bit further down the line than K&N and AIRAID boxes and I got AIRRAM's ram air piece of plastic. Only because I didn't feel like making one myself. The plan for me is to be able to rush colder air in at highway speeds to get sucked up by the intake. I am taking into consideration the rain which is why I think they're will be plenty of space for that. But for my problem isn't at take off or getting up to speed is that getting that little more oomph while up to speed, hopefully helps with towing - I'm hoping anyway.
I'll let you know how my PDC "fix" works out.....

Which plastic piece are you talking about? And, will your filter essentially just sit in the open engine compartment, just a little lower than the stock air box? no Shroud around it? And what filter are you using?
