How much dash capacity do you really need in a Titan fight? Well, more than the other guy for a start.
Turbo Engine is a Burn Card featured in Titanfall. It adds an additional dash to the dash capacity of your next Titan (4 dashes for Stryder, 3 for Atlas, and 2 for Ogre). However this only increases dash capacity, so it still takes the same amount of time to charge each dash.
