When I had the Powerdyne on my 93 Z28 Indy 500 Pace Car, I just used the stock setup they gave you but I found a way to eliminate that dryer duct hose and only use the hard plastic intake tubes. I put 42K miles on it as my every day driver and never had any problems so I'm not sure what you're looking to gain by hooking it up to a ram air setup(it's a cool idea but way too much effort and parts needed for no performance gain).
