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)

 

Lots of people always have a little sumthin-sumthin to say when they see my truck. Once they start chiming in with do's and dont's, I just smile and wave like the Penguins in Madagascar.

 

If you see him again, tell him to join up to FTE and get educated.

 

Good one Chris,lol. Maybe he,s a little jelous, i can't seem to figure out that jelous thing, be happy for what you got, i always say..

 

I love it when these guys start talking mods and you see a Banks logo on the fender...

 

or a K-N sticker,.

 

Please don't forget the all MIGHTY Bully Dog badge that gets people drooling

 

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.

 

Now i,m curious Mike, what do you use to keep the heat out and look good at the same time ??

 

I too am also very interested

 

Nothing yet. I still have to take care of this issue. I saw what happened on the dyno, my stuff soaked up and I got no added ponies for the most part from 80-120R. Too late then. Remember, those manifolds can get red hot and temps of 1200 and above will jump right into that tube due to proximity.

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.

 

Didn't even think about that, heat shield..Nice..

 

That header wrap is what popped into my mind first, but still kinda ugly stuff. I like the idea of a heat shield.

 

Same here Tag, i guess we'll see what Mike comes up with and go from there....

 

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?
