wanted to get some thoughts on thermo coating the turbo exhaust manifolds and exhaust turbines.. is worth the effort for a daily driver at around 350whp. track the car a couple of times a year, but nothing too serious.. already have upgraded the radiator and will be using the arc under tray with additional vents so i think temp wise it should be ok.. is spool up going to meaningfully increase? will it increase longevity (help prevent ex-mani cracking)? will having the coating effect the parts, inparticular the ex-turbine housing (reduction in clearance of the moving parts?) if i do go with a coating what temp rating?
