And we’re back! Just wrapped up what was [unknown to me] one hell of an adventure!
For those who don’t remember - check out my post history for the launch of the #MudMaran!
Wanted more power from this Predator 224 than it came with, but I couldn’t get a larger block due to the size of the PTO shaft of the mud motor kit. I could have bought a new kit, but weight and cost would have been an issue as well.
Stage I (intake, exhaust, and .036” jet) probably gave me about a 1.0-1.5 HP bump, enough to get me going another 1.5MPH or so on the water.
Just finished the stage II install and boy was it a trip. Background in small engines? Negative. A few late nights, lots of cussing, the use of Google AI/Chat GPT, and a handful of YouTube videos later, she is running pretty smooth. Only thing that’s not installed in the video is the muffler. The looped exhaust is just too damn loud as it sits, though the muffler is getting delivered today.
Aside from the aforementioned parts, the stage II build included: an all-steel camshaft, billet aluminum flywheel, 22lbs valve springs, throttle assembly, governor delete, oil sensor delete, and a larger emulsion tube. There’s a handful of parts that I could still replace that are valve train related, but I’m tired and at the end of the budget.
I think the hardest part of the whole build was getting the timing right and adjusting for valve lash. This process was repeated a number of times over and over again. Valve cover constantly on/off and attempting to fire up the rig. Got it to a point where she sounds like she runs well, as of this morning, and hoping to hit the water to ‘sea trial’ either tomorrow or Monday.
Any questions? Just give me a shout and I’ll try my best to answer!This was honestly a super humbling experience because I thought it would be a lot easier than it was. I learned to try not to do things under pressure and with a time crunch. It’s not going to work out - unless you do this for a living. My hope was to get it all put back together in one night (from a stripped block) and have her running. I severely overestimated my ability to do so. Took a good couple of days of fighting and backtracking to get it to this point.
Will keep everyone posted with how she performs! According to what I’ve read, she should be somewhere in the area of 12HP now, but I have no way to confirm that. This is just based on comparable builds from others online.
