Cooling efficiency is about the same per mm for both?

 

I have a Koyo. It is nice. Wrap your turbos too. That'll save heat.

 

Really? (On the turbo wrapping.) I saw that and wanted to see if it was just hype to appeal to the ricers or for real. What about turbo? Is it affected negatively or positively?

 

I can run around the block hard then hold my hand right next to the wrap, and it's pretty damn cool. Granted, i NEVER touch the wrap, but I've seen quite a bit of reduced underhood temp.

 

Its not that solid as far as proof goes, but heatwrapping has also shown like a 7 degree decrease in air intake temps that my pfc registers. This could be also be due to the weather, but it did run later the day we installed it.

 

So actual turbos aren't affected either way, just underhood temps?

 

Just get Chuck's V mount, it'll come with a Koyo rad.

Oh and what's the coating, jet hot??? I can't remember the name but I'm considering buying some for my exhaust manifold.

 

heat is trapped in the turbos. this will help increase cracking and shorten the life.

 

Dammit. That sucks the big ones.
