Screamin Eagle Heavy Breather
 

I had my doubts, but I did as the HD service tech told me. I had installed last week the SEPST in the Super with a fuelmoto highflow a/c that I already had on the bike and the bike dynoed at 77.47 hp and 89.10 lb ft tq. That made a huge difference over the stock ECM settings, but that wasn't enough for me, hp junkie I must admit. I installed the Screamin eagle heavy breather and had it touch-up tuned and what a difference that made. Dynoed at 81.12 hp and 95.44 tq. I would have never believed a air cleaner would make such a difference. Not bad numbers for a stock 96.:icon_woot::icon_bike:

Can we see the curves? Are the peaks in the same place(s)?

I have very similar numbers with a stage 1 and seprt.Next up is cams,that should make her rock and roll

Those numbers were very close to what I got out of mine with pipes, /ac and sepst. My numbers are in my sig.

'scuse my ignorance on this heavy breather contraption,but u think I could expect similar gains on my bike? 2000 fxdwg (carbed not injected).Its got T.Header,510 cams,and an open element k&n.The carb was jetted to match intake and exhaust and a thunder slide installed as well.Its in excellent tune with perfect tan plugs,and no popping. I've never really liked the looks of the snorkel,but if I can pick up 3 horse and 5 ft lbs I might have to rethink the whole matter... ;)

It might Badillac. The way the tech explained it to me was the air and fuel molicules are better atomized for burning than with the conventional a/c. I'm not a scientist, but I can tell you for a fact alot more hp and tq than I would have ever believed. I went back and edited my previous tq findings. Actually the tq was just a shade over 89 lb ft.
