Impellor Member 835 Member For: 16y 15d Gender: Not Telling Posted 22/05/12 01:44 AM Posted 22/05/12 01:44 AM From a radiant/thermal heat perspective, the heat shield being reflective is doing its best work. If painted black it would increase its ability to draw more heat away from the turbo quicker. This heat would then translate to higher under bonnet temps( up to 8%). Buy being reflective it is actually reflecting the radiant heat back onto the turbo, and further,it is the least efficient surface colour for heat transfer. This basically means that a greater amount of heat is being restricted to the turbo area. Because as we know a turbo is spooled by heat, not exhaust flow as such. To paint it black would reduce performance marginally, especially in hot weather. Due to increased intake temps. That said, this condition would be greatly reduced on FG models (due to intake location) and earlier models not using crossover. Cheers

Then what happens? 1
