Can I raise the boost on my turbo?

Possibly. Raising the boost will always place higher stresses on both the turbo and the engine, and you must carefully consider the possible consequences of doing so. For example, in extreme cases the turbine shaft may completely snap, or you may melt a piston in the engine – in any case the results may be very costly. If you are planning to raise the boost on a turbo engine it must be done in a carefully controlled manner. We recommend avoiding using single 'bleed valve' systems to raise boost – the level of control provided by this method is not adequate, and can result in boost spikes and sometimes an actual drop in performance.

What is a boost spike?
The level of boost produced by a turbo is dictated by the speed at which the turbine rotates. If the wastegate cannot react to the changing speed of the turbine rapidly enough it may briefly run to an excessively high speed (called overboost) before dropping back to its normal maximum speed. This brief excessive speed is called a boost spike, and can occasionally cause damage to the turbo or engine or cause problems with the fuel management system.
