so I was about to pull the trigger on the hypermax kit when I ran an errand to Home Depot and happened to decide to try and do it myself. I think it came out pretty good. I haven't driven it yet but install was smooth and took me about 35 minutes start to finish.
Go to Home Depot and find the ductwork aisle. I bought an oval to round adapter 3 inch with a 3 inch flexible tube. Make note on my style tube as it fits perfectly to the square to Roy d adapter and is a tight fit on the other end onlver my banks inlet. Some tubing doesn't have ends more like a dryer duct. This tube is pretty stout.
To make the firewall cutout I simply traced the shape of the duct and used a drill bit to make holes all the way around. Once that was done I used my air grinder to smooth the holes and make it a snug fit.
The only trick is to get the hood to close you still have to flatter the first half of the tube coming off the firewall. I actually set it down and used a battery to pound it flat. Once that was done I simply installed everything and used two self tapping screws on the firewall fitting and one on the tube connection to make sure it's secure.
Once it was assembled I used 3m fire sealant caulk for hvac systems as it was the only sealant I could find that had a temp rating over 140. Also trim the hood insulation right above the fitting so you have more room for hood closure. I also removed my windshield washer tank but you could easily make it work with it.I will post up how it's working tomorrow but so far so good!
