I have tried doing some research on how to snorkel. I have about 15' of 1.5" spa tubing I would like to use. I know about the vent lines and how to snorkel them. I know that I need to buy some heat tape for the tubes near the exhaust and motor. Are the belt intake and exhaust boots both 3"? What is the best way to go from the stock coupling to the tubing? What parts need some sealant, like rtv, on them? I would also like to convert to PVC for the risers (that come out of the hood). Is a 1.5" inner diameter enough flow for the belts? For the Intake,I plan on doing two 1.5" tubes. What are the chances ill need to jet?
