Manifold Heat......

I assume the stock setup uses an IAT sensor at the mass air flow sensor before it gets to the manifold? The only reason I ask is I was thinking that if you had the equipment you might be able to read what the temp sender was saying to see just how bad the air is actually getting. I've got an aluminum Indy Mod Man on my 5.7 and it's pretty dang hot to the touch, but the IAT sensor (screwed right into the #8 runner where a big vaccuum port might go) usually only reads around 20 degrees hotter than ambient while cruising (got a 6 pack hood scoop on it, but I haven't isolated the air cleaner yet). I got some phenolic gaskets with the intake (required as there are no O rings on the Mod Man), but you still wouldn't want to lean an arm on it while working after driving it. Sitting in traffic you can watch the IAT temps climb, but once you're moving again they go down pretty quick.
