Force Shorties Dyno Results
I finally took my bike down to Mitchell’s H-D in Modesto a few weeks ago to get the AF re-mapped for the new pipes. Prior to installing the pipes, I ran the bike down and had them pull a dyno run 100% stock so I would have a baseline to work with. Stock the bike was at 107.6 HP. After installing the pipes, changing the air filter to the K&N, and losing the top, I'm now getting 112.4 HP. Jack, the tuner over at Mitchell’s called me the day after I dropped the bike off and said that he didn't think the pipes were going to increase HP. At the time he recommended going with V-Mods instead. He thought there wouldn't be the backpressure that the exhaust system requires. After seeing Okie’s results, and the fact I already installed the pipes, I told him to re-map the bike as best he could. Mitchell’s charges a flat rate of $300 no matter how long it takes them (seems fair to me). Anyway, as you can see, I was able to squeeze a little more HP out of the bike. My question, does the stock headers create the required backpressure at the 2-1 point of connection? Because the Force pipes are basically wide open, that’s why the tuner thought they wouldn’t work. I had the bike out this weekend, and I’m lovin’ it! Feels like it’s running real strong. It’s louder than all get out, but what the hell, if it’s too loud, you’re too old, right? I’ll try to attach my dyno graphs for further discussion.
