V1 Powdercoating my TVS 1320

[Sparvy]

So as the title states I'm thinking of powdercoating a TVS blower I picked up recently. I currently have a ported stock M62 blower that I powdercoated the same color a year or so ago. I initially didn't see any issues with doing the TVS unit but figured I contact the manufacturer to get their input as the baking temp is 425f. Well their response was that it might warp the rotors and they could touch. Thinking about the response I noted that i believe the responder is a marketing/sales rep and not an engineer. I've seen ait temps close to 200f without any rotor issues but it is quite a difference for 425f. Anyone ppwdercoated one of these without any issues or thoughts on that temp and potential issues? Harrop said to paint it.

Temperatures above 400 degrees causes aluminum to lose temper/strength and it can cause it to deform. It only takes a few hundredths of an inch to cause problems with the rotors as TVS indicated. If you want the case powdercoated, disassemble the unit and just bake the case. That would probably be the safest approach.

Invest in a paint sprayer, and automotive paint. No risk of warping, and you can get as fancy as you want... Metallic, color, clear. I wonder if you could wrap it? Probably be a challenge, but maybe.

Yah considering the cost of the unit I'll probably either run it as is or paint itto match the bodywork. I got the M62 for relatively cheap money so I powdercoated it but I'm much more risk averse with the tvs. I appreciate the input.

Powder coating will change color even at engine oil temps. Look at the frame compared to the valve cover.

I'm not too worried about a bit of a color shift. I did my sc and valve cover at a different time than I had the frame done and while different the valve cover hasn't changed in 20ish track days and over a year of street driving. It's the possible rotor warping and case interference I'm not willing to risk.

It’s nice being colorblind sometimes.

There are powder coatings that can be done at lower temps, but of course it would have to hit a fairly narrow range of temperatures to not soften on the car.

I was hoping to use the color I used for the frame, various bits and the valve cover but I think I'm going to pivot and paint it to match some of the other body bits and avoid any possible issues with powdercoating.
