Garrett Powered Posted November 7, 2012 Report Share Posted November 7, 2012 JL audio amplifiers have the heat sinks coated with that stuff I am pretty sure. at least the slash series do and those are the best amps in the world if you ask me.

DefEddie Posted November 8, 2012 Author Report Share Posted November 8, 2012 That is definately one of the things i've thought of doing with it,as well as cpu heatsinks. I've been pushed to a decision on using the manifolds or not with the build and decided not to. So when the upper/lower are finished they'll be posted for sale,possibly with the ported tgp heads as well if they don't go on the shelf. I need the cash to finance new head parts,but i'm going to list them cheap as hell hoping the buyer will test and post. I'm on the lookout for 2 upper manifolds to run my own tests when it's finished. Initial breakin will be on a test stand and i'm going to try some controlled tests with a couple different parts/products continuing even after the engines are installed. Plan to data mine all of it and correlate as I go. To be clear though,i'm not backing out on the offer. If everybody wants then i'll send so we can get some info. Otherwise it and the lower will be finished and posted in the next couple weeks. Any chance somebody has a spare tgp upper? If anybody is willing we could run some independant testing online. Can somebody stick it in their oven to 2-300* then take it out and let it cool while taking temp measurements in x increments to track how quick it cools? Then again with a fan pointed at it? I can do the same here using my coated manifold. I remember cooloff time being a pretty drastic change. It would be an indicator if nothing else. Anyone interested? Would need an infared temp gun or thermocouple for temps (preferably both). Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted November 8, 2012 Report Share Posted November 8, 2012 would also need identical fans at identical distance with identical barometric pressure at identical relative humidty with identical ambient temps and used on an identical "cooling rack" with an identical temp gun for the results to be accurate.....

Garrett Powered Posted November 8, 2012 Report Share Posted November 8, 2012 (edited) would be a good episode on mythbusters? I have a couple extra upper manifolds Edited November 8, 2012 by Garrett Powered Quote Link to comment Share on other sites More sharing options...
DefEddie Posted November 8, 2012 Author Report Share Posted November 8, 2012 Like I said,it would be an indicator. All we can do is control as much as we can and log data. If the effects are worth the effort to try then it should be a pretty apparent in the results. Garrett,as soon as the intake is complete we can try it if you want. I could try now also,with only the top coat on it. Have you got infared or thermocouple? Let's try. Like Robert said we need to use identical fans,ambient temp and distance. Different temp utensils suck,but cumulative data will be helpful? I remember it being like a half hour/hour difference on the small block manifolds so lets try.

ShockTherapy Posted November 9, 2012 Report Share Posted November 9, 2012 in for results, i'm genuinely curious. Quote Link to comment Share on other sites More sharing options...
DefEddie Posted November 10, 2012 Author Report Share Posted November 10, 2012 If somebody would like to suggest some controlled tests to conduct i'll be glad to coat a few small peices of steel or aluminum and perform them. Then send them to someone to reproduce if they like. Just have to wait till I spray another batch of parts in the next week or so. Quote Link to comment Share on other sites More sharing options...
Garrett Powered Posted November 10, 2012 Report Share Posted November 10, 2012 I would test on the car. do an intercooler and an intake and have them ready. datalog it and dyno, then with all else same, put in the intercooler and intake that have been coated, and datalog and dyno again. at least that is what I was thinking would be a sure fire way to get the most useful data for this particular application. I know you don't have access to a dyno but do you have tunerpro? Quote Link to comment Share on other sites More sharing options...
DefEddie Posted November 11, 2012 Author Report Share Posted November 11, 2012 I prefer the hard data over a dyno really. I'm set up for OBDII and have several ways of tuning and datalogging them (TCII,TT,EFILive,ATap,etc..) As far as datalogging OBDI I am only set up for diag really (Tech1,snapon) and need a cable for laptop. Currently my hands are tied till I have the spare parts for a vehicle onhand to do a comparative swap. Unfortunately though I own 7 vehicles none of them qualify for testing because I either don't have spare parts to coat or they are drivers that I don't want to bother with. I could do one here on a 2.8 fiero intake but the results would be a bit skewed. The other intake I have for it waiting to be coated also has Egr delete as well as acid and gasket ported so it would not be an accurate comparison. I have a spare lower as well,but honestly I don't want to go through the trouble of swapping on my car. I'm just trying to keep it alive till the tgp motor is done. I might have an idea to test coating though,I'll dig around the shop and see if I have what is needed. If I find spare time i'll play a bit.

DefEddie Posted January 10, 2013 Author Report Share Posted January 10, 2013 Was at the machine shop yesterday for a few hours about these coatings. I should be getting dyno proof real soon one way or the other on how functional these coatings are. Unfortunately,it will have to be a partially coated manifold since NHRA rules don't allow any changes to the air flow passages in the intake. Hard to get it lined out,the intakes they use are hard to get ahold of and the headers they use run $1300 just for the collectors. But he is going to talk with a couple customers,and next time one is on the engine dyno (later this week or next) if customer approves cost than we will dyno engine,I'll pull a same day coating on the intake and bring it back for dynoing. (If customer doesn't approve cost then we will likely dyno an off the shelf manifold instead and then coat/dyno again. We only need customer to approve coating his manifold,not running dyno tests on another manifold. In that case I'll eat all the cost of coating for the dyno runs) Should be a good indicator,these are usually about 5-600hp n/a. I have also found a 3.1 for datalogging before/after on the tgp manifold. Forgot my brotherinlaw has a corsica with a 3.1. So just need to find some time and i'll try and get that done as well. Looking forward to getting my own results to back up the coatings. Also,I'm almost finished with an almost stock rebuild of an L67. Entire engine has been coated,down to the needle bearing cups the rockers pivot on even. If nothing else,it's alot of fun playing at the machine shop Quote Link to comment Share on other sites More sharing options...
