2008 FLHX--Engine Performance Upgrade
Need some help. I have a 2008 FLHX, Stock 96". I'm considering installing a ProCharger Intercooled System and maybe bump it to a 103". Can anyone provide some insite on the pros/cons of doing this and what else would need upgrade for reliablity. I'm concerned about the lower end; specifically the crank bearings and even the Cam bearings. I understand the 96" engines may need an upgrade to HD Cam bearings. Another issue are the hot exhaust temps that occur with the O2 sensor controlling the fuel system economy. Has anyone upgraded to the ProCharger that can pass on critical recommendations. I'm sure Engine Warranty would be out the window, but I'm not too worried about that. Any help would be appreciated.
Thanks.
Thanks.

What do you want? Most folks with baggers want torque at relatively low rpms; while turbos tend to favor high rpm power.
Here's a link to the ProCharger website dyno results:

For a bagger, and a more conventional approach, take a good look at Head-Quarters:

You can spec and price your build using this link, and take a look at the "Power Tour" article.
Good luck with your research and project.
