Foil delete...bad??
I was at the truck stop today getting fuel (do that waaay too often) and a guy asks me about the Warn hubs on my truck. Then he asks what else I've done since he has a 99 F250 sitting there beside me and wants to know about tuners, intakes, and exhausts. I showed him my AFE intake and he noticed my blue turbo pipes, he then told me I should replace the 'hot' pipe to get the insulation back because that helps to cool the air going into the turbo and I lost mileage and power by removing it.!
He pointed to the 'cold' side pipe and said the insulation cools the air going into that pipe.?? I'm not sure where he gets his info from but it was kind of irritating when a guy asks me for info about mods to the motor then tells me that I've done something wrong to mine. Do ya'll get this much? (he also told me that's why my truck is loud even after I told him about my exhaust)

The guy was right. Removing the foil allows heat from the driver side manifold to radiate and soak right into that pipe. It wasn't there just for noise.
Having said that, my foil is off. I will be fixing the problem though. It will not involve foil on the tube though.

I have considered header wrap, and exhaust shields, or an isolating piece of metal ala the Kwikk fuel feed shield. I am leaning toward an exhaust shield style setup like what covers cats etc. My concept will clamp on though so that the setup can be cleaned. Still on the drawing board.

Does anybody know the temp of the air going to the IC under a couple different pressures? I was just wondering, if it's so hot it needs an IC, couldn't some of that heat be going from the pressure side tube to the engine compartment air via convection at least partially compensating for the exhaust radiant heat?
