Hello,
I own an '05 Road King with a 95" build, Screamin' Eagle heads,
SE 258 cams, and Thunderheader 2 into 1. I currently have a
SE air filter cover over a K&N filter. I'm interested in replacing
the filter and cover with a Wimmer TriFlow Stage 2.
Question: Would there be any benefit in this swap? Any noticable
gain in either torque or HP? Currently my scoot produces 107 HP
and 105 Foot Pounds of torque (RC Cycle Dynaflow).
Thanks,
Mike

 

This months American Iron says you can get 6hp just with the swap. Check it out, easy mod and Wimmer makes nice stuff.

 

That 6hp was over a stock air filter setup............any aftermarket kit will beat out the stock setup.

The Wimmer Triflow stage 2 doesn't have a decent-sized radius at the mouth of the throttle body. Many other A/C kits do, and it makes a difference in flow. I think your SE backplate has a pretty good radius, so you may be taking a loss in HP and TQ with the Wimmer piece. But I do admit that the TriFlow looks pretty sharp!
