Just finished fixing my sled and well i had it apart i also installed a boss noss kit with a 60hp shot so will see how it works here are some pics of the install
Don't you run the risk of having the Nos run to the tap under power and climbing a steep hill? I like your install maybe a bit better then mine. The kit sure makes the hills fun only problem is the bottle is never big enough.
I had the original Boss Noss on my Cat big bore. Worked great until the nitrous solenoid stuck on. Sent it back to Boss for repair and they convinced me to update it to the new style "wet" kit like the one in your pics. Never did work and I gave up on it and took it off.
Used it this weekend and the kit worked great have to remount the bottle so it sits upright, but the kit pulled hard, gained about 300 rpm and 12mph track speed climbing on the nitrous
