Does anyone know plus or minus temperature is in the area between the heatshielding & the turbine @ anywhere from normal operating temp. to about highway speeds? I've found some aluminum ducting tape from the local hardware store that says it's good for 260deg. I know my exhaust gas runs @ about 500(cruising speed) to about 1150-1250(standing on it). How much heat would the turbine housing generate? I need to know if this tape will help or just melt.
