I know i posted this at the end of my last topic on header wrap/ceramic coating, although i think this link is well deserving of its own thread.

Heat Management Testing and analysis (DEI Heat Wrap, Turbo Blanket, Reflective Tape) - Honda-Tech

This guy has posted some real world data of temps under the hood at different locations, different engine conditions, and vehicle speeds, before and after wraping. He also included a datalog of ECT, IAT, and Oil temp. Check it out.

Edit:

for reference, this is a post i made on the same topic

Yea, hes still testing.. He has yet to wrap the DP and intake between TB and FMIC.

Hes posted this on EJ8Squad as well.

bad ass

thanks for the link

Who cares about under hood temps?

You guys got that aircooled conversion?
If the exhaust is producing a lot of heat, then the underhood temperatures go up, thus increasing temperature on anything in the engine bay. If the intake pipe or intake manifold heat up, the inlet air will increase. For peak performance you want IAT to be as low as possible. Also, high underhood temperatures can increase coolant temperature and cause the engine to overheat. Look at any endurance car and they have cooling vents for the engine compartment and heat wrapping/coating on everything. Heat soaking is a serious problem for them.

Awesome link Bone. They have a blanket for the TD04H, never seen one of those before and definitely ordering one.

Have you ever heard anything good or bad about the DEI Ti wrap in your many travels Bone? Better or worse at insulating than the fiberglass stuff? Durability?

Never paid attention honestly. I used DEI fiberglass wrap on my Stillen header, you know the ceramic coated header that should have rusted to death in two years with Ohio weather, yet is still going strong on a 4th or 5th car. I bought that header in 1996 and it has not rusted through yet.

Ha, every time I see someone bashing wrap and saying it'll rust your headers I think of the pictures of your header, with the rusted unwrapped section. I like how you can kinda see the pattern of the wrap on the nice part too.

Honestly I only wrapped the header so the now down stream O2 would get a better reading. This was before I knew about heated O2's.

Whenever the issue about the headers rotting away from being wrapped, I submit my pics and the thread goes dead.

While I am clueless on turbo blankets, I do know them from Buick ideas, I'm always up to support my locals.

not sure if this helps but im running a turbo blanket on my setup it reduced under hood temps and DECREASED spool time by 200-300rpms. i can put my hand on the turbine housing for a few seconds without getting "burned". also prior to blanket the intake manifold would get heat soaked by all the heat too hot for me to touch. my carbon fiber hood wasn't burning up and discoloring anymore after i bought the blanket. another thing i noticed was when i first popped my hood i wouldn't feel a rush of hot air hit me in the face anymore. with the blanket my intake manifold is a lot cooler to touch. I have a FIBERGLASS material blanket it STINKS and is less efficient compared other type of material used. the pulverized volcanic rock can withstand a few hundred more degrees than the one i have and also i think the "finer" the material = denser meaning it covers more surface area than fiberglass.


PTP test. i can barely put my hand on mine for a few seconds so yes the fiberglass ones are inferiror

I used the fiberglass and it works once..

meaning its not made to be taken off and on. But it did cool off my temps.

The DEI also works great and friends have had alot of good things to say about them.. They better for the price of one of those things.

The DEI stuff is very good for stainless, as it is not full of chlorinated products that can and will cause corrosion on most stainless headers. Most cheaper header wraps are not good for SS stuff, but okay-ish for mild steel. I prefer using the DEI stuff, though.

I also have the ti wrap on my down pipe till the first v band then I have the the regular fiberglass stuff after that and the ti stuff stands up better and blocks a little more then the fiberglass. I also think it helped with my oil temps. I haven't installed my oil cooler yet and before I wrapped the part of the down pipe that went under the oil pan i could tell it was getting to cooking my oil because it would get dirty quicker and looked like it was loosing its viscosity by running off the dip stick quicker
