I have the Dragon with the BD garret 28 turbo,,, works great and runs pump gas....the garrett28 turbos run with oil so I think they last longer and easy to get parts to fix if need be...
I tested the kit from HM Turbos last year and it was by far the cleanest and most complete kit that I have seen. I pre-ordered his custom "Flyin Hawaiian" sled(Dragon 8w/turbo), and am looking forward to picking it up nest week and getting some seat time. Check out the website: HMTURBOS.COM and tell Shane that Bigfoot sent you. He told me he is setting up demo rides in Idaho, Washington, Montana and Oregon this winter to let people see and ride the kit he engineered with Aerocharger.
I have a kit from HM Turbos, and for the money there is no cleaner or easier kit to install. It was designed in partnership with the guys at Aerocharger so I knew it would rip!! Give them a call, their website is HMTURBOS.COM Ask them about the Air to Water Intercooler, I have it and my charge temps are running about 135 degrees @ 5,500 ft elevation running 10 lbs of boost. PM me if you have any questions.
