you can get 5 farad 24v cap for like $300 and a 10 for like $550. I don't have much information on this type of turbo, but at 24v to 30v and 5 farads, you should be able to keep the turbo running at max boost until the alt/bat can keep up again. also i think a 2nd battery might also be a good idea in conjunction with a cap, because wouldn't a battery just be too slow to use "in time of need" it should be similar to the way car stero guys use a 2nd battery and cap...
