TURBHOE

iTrader: (4)

While I was doing some turbo reading I found some interesting info. In short it said wrapping the manifold and what not is good but not the DP. Reason being is, if the DP is cooler than the manifold feeding the turbo i.e. it’s aired out by not being wrapped, the heat will expand to the cooler DP (or some ****) and make the turbo spool faster.

Ok so I can't word it like they did when its 1 in the morning. But in short, short it makes the turbo spool faster by helping the heat transfer help spool the turbo. Has to do with the expanding gases crap.

This is true. You want to conserve heat before the turbo, remove it after. This is why wrapping the crossover makes the biggest difference (its thin wall, cools faster) On the other hand, colder air in the downpipe will reduce backpressure.

Makes sense. I've read the same thing on a few other forums. I think for my truck, I'm still going to wrap the DP's in the engine compartment. I think my exhaust is free-flowing enough (two 3" DP's, 3" madrel pipes/X-pipe, two 3" Random Tech muffs, two 3" tailpipes) that I'll take the reduced under hood temps.

How much are you guys spending on wrap to do all this? Just seems so much easier and cleaner to get the pipes coated.
