I'm currently running the stock filter with the screen removed and debating whether or not to switch it out for the F1-85 filter. I've watched Brock's videos on the potential gains over stock with screen removed/competitor filters, and read comments from forum members who merely stated that they are running the F1-85.
Since the Sprint filter has been out for a few years I'm curious to hear from those who actually run this filter on whether or not they encountered any issues from using it over a significant period of time. Were any real world gains felt over the stock filter? The gains on the dyno according to Brock is 1.5 HP over stock w/screen removed, and potentially 5-7 additional peak HP during real world riding since the dyno doesn't account for the RAM air effect.
So far my bike is flashed with a full Brock's exhaust, running Brock's PumpTrack fuel map which according to him, accounts for the increased air flow if I were to switch to the Sprint filter. I don't drag but occasionally do some roll ons with my friends when we travel to Mexico. Any feedback from those who have any real world experience with the F1-85 would be greatly appreciated.
Thanks
