wrong? I use powder coating on plenty of engine components of 400+ HP turbo applications with great long term results (not including turbine cases and direct exhaust components). Our engine cases dont come anywhere near the temps to harm a quality, properly prepped and applied powder job.um... wrong. Use a high heat coating/paint. not just normal.
Yup. I've powder coated "hot" parts on plenty of 911 motors over the years. Plenty of valve covers, timing chain boxes and covers, engine tin, fans and housings, and stuff like that. Never a single problem with heat. Granted, I would never use it on "really hot" parts like cylinders and heads because of its insulating qualities, or on "really freakin' hot" parts like headers or mufflers because it would just burn off. Everything else has held up just fine, though.wrong?
