How much longer is this coating going to be exclusive to the secrets club? Looks promising.

Yeah me too, I would love to find out and it does look awesome on there as well. heck I might even do the same thing. till I find out what kind of paint that is and also how it turns out.

We ice down our superchargers between runs at the track also. It'll be interesting to see how this finish holds up to the heat/cold shock at Woodburn in a few weeks.

Edit....this is this morning'* view:

The reason for the name being held back for some time is to get hard data and test results in. In many cases some of us in the staff have noticed a good portion of the performance desiring population to run out and buy something believing it to be a great solution while one of us may have bought it as a test w/o any good data to back up it'* merit.

Basically..to keep others from possibly spending where spending may not need to be done.

It turned my SC black.

I'm running it through several de-greaser/detailing cycles, and as the summer temps increase, I'll know more.

So far, so good.

Yes, Will, please tell us!

Sorry to get off topic for a minute, but I must add that the picture of you "cooking" your SC on the stove with the infared gun is hilarious. What would somebody think if they didn't know what you were doing? Let'* say you burned down your house there and the inspectors find a SUPERCHARGER on the stove?! :P The stuff you do in the name of science.... keep it coming man.

Once again, as already stated by myself and others in this topic, until I know it'll hold up to typical chemcals, solvents, and degreasers, as well as extreme temperature cycling (high-boost sprints followed by icing down), I won't say what it is.

I'm not going to have 2 dozen cars try this only to find out it flakes off within a couple months of summer heat and an engine wash.

Via PM'*, but I thought it would be nice to capture it here:

You didn't read it. You don't WANT a polished surface. You want rough or textured for better heat transfer. The color has VERY little to do with it. It'* all about surface area.

Thermal conductivity and heat transfer in this case are enhanced by increasing the surface area through inducing irregularities with the coating. In the same way the fins/ribs over the supercharger do, on a smaller scale, but over the entire surface. The Black Body theory may be partially responsible for the increased thermal transfer rate that I proved, but the textured finish is the primary cause of the result.

This isn't your garden-variety textured paint, either. It'* a formulation that should withstand everything I throw at it under the hood.

I have read many of the SC and L67 related topics and must admit that the unknowing of this paint was enough to get me to register, I am about 1 month from the completion of a project in which this paint will be very useful so I thought I would post my desire to know as well, though I do sincerely appreciate your concern for standing behind a solid product

and here it is in to Sept and how is it doing

and do you think it had any thing to do with the issue with the chipped piston maby to cool of a charge in to the combustion chamber shocked the piston over time ?

any how next time you need a charger and TB to do some work on let me know i have a spare set now
