Agreed, I don't like wasting money either...and more than likely you will be fine at your power level....but when you look at the cost of your engine AND trans, what's another couple hundred bucks on a $8,000 - $10,000 set up (just guessing on price)? I mention the trans because if the crank lets go it will probably hurt the trans too.....but, to each their own. If you are comfortable with the risk then hammer down my friend :-).
