MotorStorm: Pacific Rift Tips

Boost turning
There are two ways to turn corners while boosting, both of which give different effects. To turn a large corner that is not very tight but requires the turning button to be fully pressed for the duration of the turn you should begin boosting before you get to it and then continue the boost as you turn through the corner, only letting off at the end of the corner or when your boost meter is too high - any further cornering is done using the handbrake and more boost.

To turn a tight corner while boosting you should let off the boost before entering the corner, just after you press the turn button fully then turn on the boost which will allow your back wheels to skid and as soon as you straighten up you will leave the corner with maximum acceleration.
