Honestly. Opening your own shop WITH a brand new dyno, new equipment and what not requires LOADS of capital. I know from watching Jack open P1 auto in Charlotte. He wont be making profit for a WHILE. You're going to start in debt and be in that debt till you have made a name for youself with people who are willing to lay down the big bucks for work. Im sure you've considered this already though. But an AWD dyno capable of 2wd runs would be wonderful. Heck, if even volunteer to work for you for pennies if it gets up and going. Good luck.
