View Full Version : thermal dispersant messing around

i've decided to play around with some dispersant because there really hasnt been much in the way of actual data out there. until now i've just used thermal barrier type coatings so this is new territory for me. i know alot of people put grill paint on things like intercoolers and radiators but i think it would be cool to be able to black them out AND have function to it.

a little info about thermal disperant:
"Being able to move and control heat is of tremendous importance. Excessive temperature can lead to metal fatigue, boiling fluids, damaging metal expansion, reduce electrical efficiency and a host of other problems. Traditionally dealing with heat has been handled either by expanding the
radiating surface, constructing parts from materials that are more heat conductive and using the color black. With advances in thermal management methods additional ways of enhancing heat trans-
fer now exist. Individual products such as TLTD can be utilized by themselves or in conjunction with other coatings to manage the flow of heat. TLTD is capable of transferring heat faster than the bare metal surface. While TLTD does make use of the color black, TLTD is more than a simple "black body" heat emitting coating. TLTD includes ingredients that also contribute to increased heat flow. Combining these properties with increased corrosion protection and the thin film application technique, maximizes thermal transfer capabilities. Effective on Brakes, Intake
Manifolds, Cylinder Heads, Oil Pans, Radiators, Intercoolers and more.
"


with that said, we decided to start with a tmic off of an 02 wrx. i got two things accomplished; baselining some temps from an uncoated tmic, and got the tmic sandblasted and coated with thermal dispersant. i'll post up my baseline temp points soon.

I'll be interested to see what the results are. Unfortunately this product, by virtue of physics, has to go both ways.

If it can make a tmic disperse heat quicker, then, by nature, it will also allow for faster heat soak.

baseline results. in retrospect i would have done more start and stop to see how quickly the IC gets cooled after heatsoak because this is where i think it would be most effective. these are baseline uncoated results.

kellogg, 11th and maryland are about a mile apart. i should have done alot more driving and less idle temp taking.

ok so i have some more raw data here from testing. i'd say i'm pretty happy with the results. i believe i see a high of 26% cooler temps in the data. ambient temps were very similar to the other night of testing.

Driving portion of test. Blue is coated, pink is uncoated.

First 1/3 car idle after getting back to the shop. last 2/3 car sitting off. Last data point is 21 minutes after the car was shut off.

damned! can't argue with that......excel graphs and everything, nice work!

sooooo, link to the product? is this spray on, or something you have to bake on like ceramic coating?

haha yeah, those are graphs are about the only thing i know how to do in excel other than filling in boxes. well i guess i really dont even know how to do the graphs...didnt know how to change the series 1/series 2 labels to something more meaningful. stupidn00b


as for a link to the product...we really dont have much on our website for it because we are just messing around with the stuff first to see if it works. i'll try to get something up on grimmspeed.com soon for you though.

well, I just happen to be an excel expert. So if/when you want to make those graphs look nicer for your website, let me know and I can help you out there.

That is really cool! no pun intended :-) I have to see where I can get some of that.

BASF might have something like that lying around the ware house.. I will have to see when I am back in MI again... but other wise I will take a quart of that stuff!

Oh I wonder if it would also work on the intake manifold?

they have it (look at their website). I'm thinking I'm going to get that done pretty soon.

I did! :) still driving around on it a bit more before I do a write up, but so far, definite improvement between 2.5 and 3.5K rpms. Above that its hard to tell on the butt dyno. Initial throttle response is nicer too....and this is still with my stock up pipe in place. those header gaskets you sell are nice too, I could see black carbon deposits around the exhaust where the OEM metal gaskets were leaking a little.
