...... good article, still can't help but think.....about a turboed car, say in comp eliminator, or maybe super stock, [don't know the rules] and decide to set a record or maybe have a tight race next round, crank up the boost, and spray water, do not know how it would work, but as I read it, in that scenario you can get a short term HP increase.
