Water/Meth System

Mocking up the water/meth system. Goal is to get the nozzle plumbed in the supercharger for maximum efficiency. Will be downsizing to a 2.87" pulley.

Working with Severn Tuning. If you guys are thinking of going this route, I highly recommend you reach out to them.

Finished plumbing the tank and pump. Had to create custom brackets out of aluminum to mount the tank and pump and attached them with rivet nuts.

Still need to complete the wiring but I switched over to working on the supercharger. Carefully drilled and tapped the location for the nozzle.

Next step is to replace the pulley with a smaller one and to remount it back in the bracket.

I hope to get the wiring completed by the end of the week and then start working with Severn again.

I’d be uncertain about that.
