fter many years of loading and unloading my home made Igloo Nitrous Bottle Heater from the truck bed at the track, I finally decided to make a new one that mounts permanently in the trailer. I didn’t have enough room for the bigger igloo setup so this narrower aluminum one will be really nice to have.
Kurt Riffle from Riffle Motorsports had an old tank he had laying around since he used to run Nitrous and I talked him into modifying it a little for what I was wanting to do. He added some additional drain bungs, and a pad to mount a snap action safety temperature switch to the side. That safety switch is something I’ve been wanting after witnessing a controller malfunction due to a bad sensor and stay on causing the bath to get too hot, obviously that would be a very bad situation with nitrous bottles that we want to avoid.
Last year during tear down when I was inspecting the pistons, I noticed a bit of piston rock had been going on. Not terrible, but just enough to scuff up the top of the piston near the top ring – more than I’d like. The piston skirts didn’t get knocked in, no excessive cylinder clearance – just big piston and a short skirt I guess.
