March 26, 2006 Turbochargers not only generate lots of engine power but they generate over 1,000 degrees centigrade of heat, which produces significant detrimental side effects. We’ve written about UK-based Owen Developments, before. The latest from the Oxfordshire turbocharger technology experts is a range of turbo heat shield jackets developed to fit most makes of turbine housings including Garrett, Mitsubishi, IHI, KKK and Toyota. The jackets offer four major advantages, the most significant being that by retaining heat within the turbine, the hot and expanding gasses will have the effect of increasing thermal efficiency of the turbine design. Bottom line, it’s an additional long term horsepower boost for £82.20 (plus VAT if you’re in the UK).
The jackets are made from a special mineral based ceramic material, capable of withstanding a temperature of 1,250 degrees centigrade, enclosed in a high temperature absorbing exterior cover. They offer four major advantages.
1. By retaining heat within the turbine the hot and expanding gasses will have the effect of increasing thermal efficiency of the turbine design.
2. Rapid temperature changes can contribute to turbine fatigue and subsequent failure. Controlling the rate of temperature change to a more uniform level will increase the serviceable life of the turbocharger.
3. Insulating the turbine housing enables work to be carried out under the bonnet, in and around the turbocharger area, with a reduced risk of burns to the hands, wrists and arms of the technician.
4. The insulating properties of the turbo jacket will assist in reducing underbonnet temperatures of race and rally cars.
