so, would you all say that doing this and wrapping would make a huge difference? my dp and hotside are wrapped. how big of a difference would it be from what i already have? I am using an txs topmount and i still want to take more heat away. so yea, any info would help

 

It would make a noticeable difference, however you should read the thread i did on my heat testing...once you start driving over like 30mph, the engine bay cools off quickly to the point where it probably wont make a difference. Makes a much bigger difference in traffic or around town with stop lights.

 

Looks good. Did they happen to mention to what temp their coatings are rated for? Did they have a choice of colors? Pricing?


stiscooby - If you're wanting the just coat the parts you've already wrapped...then no it won't make a big difference in temps or performance. The reason you still have high-ish underhood temps is prolly more due to your un-wrapped pieces (UP, exhaust manifolds, crossover pipe). Coating them would help with underhood temps...which is just a byproduct of the real benefit of increased exhaust gas velocity (i.e. quicker spool).

 

so it would be extremely smart to wrap the header and up? so, i bet i would have to get a retune for it to work efficiently? thanks guys for the info

 

Yes, if you wrap the header you will have quicker spool just like the d/p. So you will want to retune.
