Why does back turbo get cherry red just after a few minutes of driving?
The back of the turbo, is the turbine. It has the hot exhaust gases flowing thru it. The exhaust gases are 1000+ degrees f. and cause the steel to glow red/yellow when under load.
Many Porsche's have back seats. For example.... PORSCHE CAYENNE, S, TURBO, GTS, TURBO S, TRANSABERIA PORSCHE 996 CARRERRA, TURBO, S, 4S PORSCHE 944, S, S2, TURBO PORSCHE 993 CARRERRA, TURBO, S, 4S PORSCHE 928, S, GTS PORSCHE 997 CARRERRA, TURBO, S, 4S Porsche PanameraS, Panamera4s, Panamera Turbo. ETC..........
Look on the front timing cover. If it says 7MGE it is non turbo, if it says 7MGTE it is a turbo. You can look on back below taillights for turbo emblem. The turbo motors also usually have a black plastic cover over the front of the motor that says turbo. Easy way is look on left side of motor where the exhaust is to see if there's a turbo or not.
