As a 3rd party observer...
Geo says that Swain's White Lightning can cut heat throughput by over 50%, so just using that as a comparison for performance (we'll disreguard longengivity for now), what percentage of heat is retained by using DEI or thermotec and special coating?
also, what special coating is needed, is it a hardner for the wrap, or an additional thermal type spray?
thx,
-sd

You may get slightly more energy retention using a coating IN ADDTON TO, but it does not outperform the wrap.
Mark - why do you need a compressor to use my procedure?

Anyone familiar with this company?

Their data looks interesting and the prices are good. Swain's is great but about twice as much.

What data do you actually have?

Most header companies use this type of coating because it looks pretty and will last longer than paint (which pretty much won't last at all on an uncoated header). Swain's coating can be painted and I did just that with my high output 2 liter SR20DE (Nissan) header. Never had a problem with the paint.

I have datalogger RESULTS - not just marketing bull**** put out by the company that anyone can Google search on
I have 150 RPM better spoolup with the wrap.
You guys can listen to me (look at the output of my turbo......), or you can rely on ulta partial fairy-dust magic-coatings company.

How does THAT compare to a wrap?

ST,
Have you run Swain White Lightning coated headers? You have datalogs, great, but you haven't answered that question, yet.
I plan to run Swain coatings on my headers and cross-over, so an answer to that question would be appreciated.

Must be the exact same car, header and/or turbo or your data is meaningless.
Just because your turbo puts out doesn't give you credibility in this matter.

I don't have them saved - I remember the results. I have made THOUSANDS of 944 related datalogs. You don't even have a logger, do you Geo?? Just another Rennlist speculator, I guess.
The difference is HUUUUGE - this topic of arguement is insane. The is no comparison between a DEI fabric wrap with a special spray coating and fairy dust magic coatings.
If you want to keep heat in the pipes - you wrap. Although - it won't be nearly as pretty as those fancy-pants, expensive coatings. So if you want a bling-bling home-boy set of pipes - get the coating.
By the way - to let you guys know how serious I am about REAL information - I have an aviation-grade EGT scanner, that tell me the temp of each individual pipe, or which one is hottest.
Who do you think knows the most about the inside of a 944 engine here????
