| | No matter what the driving condition, altitude or even ambient temperature, the EGT should not exceed 770ºC. | | In fact, we are more comfortable with 720ºC for that extra peace of mind. | In most cases the maximum EGT will only be reached when driving full throttle, but with diesels that's more often than not. | Towing even a small load would also bring out the maximum EGT. | Some diesel turbos exceed the maximum permissible EGT while driving at a constant speed of 120 km/h. | The biggest problem is and will always be - How will you know what the EGT is if there is no gauge to show you? | Our experience is that with the help of the EGT gauge you can also achieve extremely good fuel consumption because it is directly related to the EGT. | | | | | What if the EGT limit is periodically exceeded? | Piston crown failure and cracking is very common, however different makes and models use different material for pistons and sleeves. | Some can handle the excessive temperature better than others. | The first area that will take strain is the exhaust manifold and the turbocharger. | Exhaust manifold cracks and/or broken studs are a first occurrence. | The waste gate valve area in the turbocharger starts to melt and because one cannot see inside the turbo, you wouldn't know. | |  | | The colouring of the turbo is one way of establishing the inner condition. | If the turbo is a shade of blue, the damage is probably already there. | Once the waste gate has any sign of damage, the boost pressure will change and once again one wouldn't know because there is no boost gauge in the vehicle. | The cylinder head in the combustion area starts to crack, just light hair cracks at first and eventually they crack into the water channels. | Piston crown failure and cracking is very common, however different makes and models use different material for pistons and sleeves. | The cylinder head in the combustion area starts to crack, just light hair cracks at first and eventually they crack into the water channels. Piston crown failure and cracking is very common, however different makes and models use different material for pistons and sleeves. Some can handle the excessive temperature better than others. | Engines that continually exceed the permissible EGT, generally don't last more than 60 000km before they fail completely. | Surely all this information will make one wonder why vehicles today aren’t all fitted with EGT gauges as standard equipment. | Fitting an EGT gauge will not affect your new vehicle warranty and is there to help preserve your vehicle's engine and save money in more ways than one. | | | | |  | | | | Exhaust Pipes, Branches, Headers, Manifolds and Wildcat exhausts available for most petrol & diesel vehicles including Alfa, Audi, BMW, Chev, Chrysler, Colt, Ford, Honda, Hyundai, Isuzu, Jeep, Kia, Mazda, Mercedes, Mini, Nissan, Opel, Toyota, VolksWagen and more... | | | | |
