Turbocharger FAQ from: Motorsport Developments - Turbocharger FAQ What type of oil and how often should it be changed?Turbos must have good quality oil. Use either a semi or fully-synthetic engine oil. We recommend Mobil1 Motorsport, Castrol RS, & Comma XT2000. Change oil at intervals recommended by the vehicle manufacturer or sooner.How long does a turbo last ?On average, about 75,000 miles with regular engine servicing and good quality engine oilWhat is a dump valve ?A valve which relieves back-pressure between the compressor outlet and engine as the throttle is closed. Only sometimes required on engines producing in excess of 14psi boost pressure. A "whoosh" type dump valve does the same job but dumps to atmosphere instead of to the intake and produces that hissing sound. It also removes the hot air that a standard re-circ dump valve actually makes the turbo Re-Heat!!Can I fit a turbo from another car ?No, virtually all turbocharger are different inside, even if they appear similar on the outside. The turbo model e.g. Garrett T3, is only the model, not the specification.What is a hybrid turbo?A hybrid turbocharger is a special, which combines similar boost response to the original but with the extra air-flow capacity needed for more power at higher revs.Can I increase the boost pressure on my engine?Only if the engine has been modified to accept these changes without forsaking reliability.Should I leave my engine ticking over before it is turned off?Not for normal every day driving, but it is ALWAYS worthwhile. Always do so if the engine has been under load or raced before being turned off. e.g. Motorway driving, Towing a caravan or after climbing a long incline.Why is it important to balance a turbocharger?Without highly accurate balancing, vibration will create a whining noise, reduce turbo bearing life and reduce turbo efficiency.What should the boost pressure be set too ?This will vary for every different car manufacturer, seek their advice before adjusting.How many Psi in one bar ?14.7 Psi = 1 barCan I fit a bleed valve ?A bleed valve reduces the signal pressure to the actuator wastegate. It has the effect of increasing the boost pressure. Engine damage will result unless the engine is previously modified to accept this change.Are all actuators the same ?No, each has a different opening pressure and rate.Oil in the turbo inlet pipe - Should I be concerned ?A small amount of oil usually exists, drawn in from the engine's crankcase breather system. High engine wear will increase the amount of oil found, and will require further engine tests (not turbo).Can I fit a high-flow air filter ?Yes, but only if the quality of air filtration is no less efficient than the original manufacturers filter. Poor filtration will cause the turbo compressor blades to wear, resulting in reduced turbo efficiency.Should a turbo be serviced ?No specific turbo servicing is required, but regular quality engine servicing is needed to reduce the chance of turbocharger problems.What is a water-cooled turbo ?The central part of the turbo, housing the bearings, is surrounded by a water jacket through which the engine's water coolant is passed. This water continues to circulate after the engine is turned off, cooling the turbo, and preventing heat soak.What is a 360º thrust bearing ?This is an uprated turbo bearing. It has a greater bearing contact face to withstand the high loads which would otherwise destroy a standard bearing very quickly. Mainly used on competition and hybrid Turbos.Why is my car smoking at the traffic lights ?One of the typical early symptoms of a turbocharger problem is a hazy blue smoke being emitted from the exhaust tailpipe whilst the engine is ticking over.How noisy should a turbo be ?Only an unbalanced, worn out or damaged turbo will produce any significant turbo noise. (unless you have a conical filter fitted which in effect removes the silencing properties of the O.E airbox.)What is an intercooler ?A special type of radiator which cools air before it enters the engine. As a turbo compresses air, the air heats up. Power can be increased if the air entering the engine is cooler.

A classic car revival has been sweeping the continent for the last decade, bringing new enthusiasm both for classic cars and the latest models of certain classics as companies roll them out. The Grand Prix from Pontiac is one of the few muscle cars that has enjoyed continuous production since it first came on the market in 1962. Today the Grand Prix is Pontiac’s largest car, with modern innovations in power drive and emissions making it cutting edge technology.

As with most muscle cars developed in the 60’s and right through the 90’s, though, the Grand Prix lacked an efficient system which would generate the power it needed in order to be truly impressive without costing an arm and a leg when it came to fuel. Not only the Grand Prix, but virtually every other model of muscle car suffered in popularity not due to a lack of enthusiasm over form or power, but simply due to practicality.

Today, it is possible to breathe new life into your classic Grand Prix by fitting it with an after market turbo charger or turbo charging kit. The intake pressure of standard cylinders is determined by the atmosphere, whereas a turbocharger puts more control into the hands of the vehicle owner. Turbo chargers work through forced induction; a compressor forces more air into the cylinder at the intake point. Because there more air, there is also capacity to burn more fuel, which will allow the car to achieve more power per compression.

Turbochargers are more efficient than other power boosts such as superchargers as they use the emissions of the engine to drive the turbine, rather than a belt that is connected to the engine. Belts necessarily take away some of the power from the engine overall; the use of the exhaust to drive the charger means that instead of taking power out of the equation, the mechanism is effectively recycling an already occurring by-product.

In order to truly breathe new life into that Grand Prix, you will need to make sure that the engine does not waste power due to back flow; thus the need of the entire turbo charger kit. Kits are designed to reduce backflow around turns in the exhaust system through waste gates and bends in the pipes. Too many bends mean a lot of different welds, increasing the chance of leaking exhaust gases and a resultant loss of power, but a kit which incorporates only one or two bends will mean less possibility of leakage.

If you’re looking for an efficient way to bring the power back in your Grand Prix, a turbo charger is a good way to go. You’ll be able to use more fuel in a cycle, and the fact that the charger uses the emissions to run means that there is no compromise in terms of power output.
