Fitted thermal insulation blanket to suit an internal wastegate T28/GT28.
Direct theft from Horsepowerinabox website:
"This model is for an internal wastegate turbo of a small to medium size, eg GT25-28.
These Blankets are a great innovation to the turbo scene! They are made up of heat proof silicon coated fibreglass cloth, with an inner of 25mm Heat Absorbing material, and a stainless wire mesh to retain the "wool". The Wool is space age technology material with tolerences in excess of 1000 degrees C before mechanical breakdown of the material.
The Blanket is designed to retain the heat in the turbo, reducing the loss of energy/heat from the turbo. This intern gives the turbo earlier spooling and greater horsepower potential. Back to Back Dyno Testing verifies a performance increase from fitting the blanket. Not to mention the cosmetic benifits of reduced temeratures within the engine bay! No more burn't paintwork and cooked wiring looms etc."
Was fitted to my T28 for the drive at Easter from Canberra to Jamberoo & back only. No longer needed due to turbo upgrade.
