Altitude With Attitude
HOW DOES THE JEEP TURBO SYSTEM DELIVER SEA LEVEL PERFORMANCE AT HIGH ALTITUDES?
A turbo Jeep uses a wastegate. This is a valve that diverts exhaust gas away from the turbine wheel. Diversion of exhaust gases regulates the turbo speed. The primary function of the wastegate is to regulate the maximum boost pressure to protect the engine and the turbocharger. One advantage of using a quality wastegate is to allow you to use a smaller turbine housing, resulting in less lag time before the turbo begins to spool and create boost. Tial wastegates are the pinnacle of quality and reliability.
Wastegates use air pressure to overcome the spring tension that holds the wastegate valve closed. The tension of the spring installed in wastegate determines the boost pressure of the engine. As long as the wastegate valve is closed the turbocharger speed will continue to increase until the sensing line applies enough pressure to overcome the spring tension and open the valve. The desired boost pressure and the selected wastegate spring are directly related. Elevation and air density have little effect on the boost pressure. During conditions of high altitude the wastegate simply stays closed longer and the turbocharger speed increases until the sensing line applies enough pressure to overcome the spring tension and open the wastegate valve. The user has to do nothing to achieve sea level performance at higher elevation. The wastegate by design does all the work, all the time. In order to achieve sea level performance at increased elevations, Jeep supercharger systems require you to change the supercharger pulley and the drive belt to increase the speed of the supercharger. You typically cannot use the same supercharger pulley in high elevation and at sea level. So when you come back to lower elevations you need to change the pulley again because it will now make too much boost.
The Prodigy Performance turbo kit for the Jeep Wrangler uses the best wastegate on the market. We strategically locate our Tial wastegate in the cooling fan shroud. This helps cool the wastegate. Prodigy Performance fits each wastegate with the proper internal spring to ensure specific boost pressure is achieved. We use push lock air fittings to create a proper seal to the sensing line and this also eases installation. Prodigy Performance Jeep turbo kit delivers more power under all conditions.
