Okay, so I’ve been messing around with my Harley, specifically the Milwaukee-Eight 107 engine. I wanted to see what kind of horsepower I could squeeze out of it, you know, just for kicks. It was a pretty fun ride, so let me tell you all about it.
First thing I did was get the bike on the dyno. I wanted a baseline reading. Gotta know where you’re starting from, right? It’s like weighing yourself before a diet. I found a local shop that lets you rent dyno time.
After I got the bike all strapped down and hooked up. I let the dyno rip, recording the initial horsepower and torque numbers. These base numbers, helped me get a base idea of where I am, and what I’m working with.
Then came the fun part – tweaking stuff! I started with the basics. Installed a free-flowing air intake and a better exhaust system, because you know the engine’s gotta breathe. Changed a couple of things from the stock setup, and I feel like it made an impact.
Next, I messed around with the fuel mapping. I use this Power Commander thingy, basically a little computer that lets you adjust how much fuel the engine gets. I played around with different settings, took a bunch of runs on the dyno, I watched the numbers change on the computer screen, and I got super into it.
The Results
Air Intake: Swapped out the stock one for a high-flow intake.
Exhaust: Got rid of the restrictive stock pipes and put on some slip-on mufflers.
Fuel Management: Used a Power Commander to fine-tune the air-fuel ratio.
After each change, back to the dyno! It was a lot of back and forth, adjusting things, running the dyno, seeing the numbers, tweaking some more. Kind of tedious, but also super satisfying when you see those numbers go up.
Honestly, I’m no expert mechanic. I’m just a guy who likes to tinker. So, I did a lot of reading on forums, watching YouTube videos, and just generally trying to learn as much as I could. It was a learn-as-you-go kind of thing.
In the end, I was able to bump up the horsepower quite a bit. I’m not gonna give exact numbers because, well, every bike is different, and my results might not be the same as someone else’s. Plus, I’m not trying to brag, just sharing my experience.
The whole process was a blast. It was like a puzzle, figuring out how to get the most out of the engine. And the best part? Now my bike feels more powerful and responsive. It’s just more fun to ride!
