I picked up a 2010 challenger 180 with around 120 hours on the 215hp set up last May. After the first couple outings with adults and large dogs on board I wanted a little more power and the supercharger was due anyway. I'm a tinkerer that can't keep my hands off of anything but was a little surprised at how little information I could find on upgrading boats vs skis so figured I'd document my journey in case it helps anyone. Apologies for the filth in the boat and crazy wires everywhere the previous owner had some interesting wiring solutions I haven't entirely understood/fixed yet.
Currently Installed
-Rebuilt X Charger
-48lb injectors
-Riva race plate: I strictly did this for the AFR sensor port. The performance gains are interesting if they meet the advertisement but not needing to drill my exhaust manifold saves me time and pucker factor.
-Removed internal intercooler and installed block off plate and reference vacuum/boost line for the RRFPR
-Rising Rate Fuel Pressure Regulator and Riva tank adapter: I used a cheap one off of Amazon, I will probabaly upgrade it in the future or live to regret it but it had decent reviews and in initial testing it holds pressure and doesn't leak.
Future projects
-Fizzle GenX Intercooler: I think i have a way forward and I will share pictures once it's complete. I tried a few different mounts and hoses from skis but none seemed to fit how I wanted or line up to the boat where i want to mount it. I ended up buying a metal intercooler piping kit off of Amazon and have the location and orientation mapped out. I'm going to route water lines the same way the 255hp is routed with a T feeding the intake of both the intercooler and exhaust manifold simultaneously as well as expelling the intercooler and exhaust manifold off of one line with a T fitting.
Install AFR Gauge. Im debating on running it all the way to the dash for continuous monitoring or put it somewhere in the back where its easier to mount and wire. I need to monitor closely to get the fuel regulator set but after that I'm wondering if the gauges alarm is enough to warn me if I start running rich/lean.
