[@deviantrebel6326]

So, did you use aftermarket case? Heads? And could you put a link to where you got the kit and also what all machine work is needed?

[@trueaussie3097]

I have a 99 fat boy “80ci” with a 96ci kit, s&s carbi Vance and Hines short shots makes 120hp thing is a weapon

[@robertsullivan2289]

sounds great, Iam about to do exactly that. Iam thinking a thunderheader. thanks for sharing

[@HiOctane11]

I own it now and it has Thunderheader :-)

[@whatyoumakeofit6635]

All said and done, is the effort and cost of doing this worth it ? Numbers aside, how much of a power difference is thetr when actually riding down the road? Is it that much more fun to ride ? How os acceleration and high speed cruising power?

@@kennethwise7108 right, mid year 94 HD changes from the flange on top to flange on bottom. So one has to be aware which studs are being used when replacing. You can replace the old style with the new, but then the flange goes down, if replacing old style with old style, flange goes up, like OE. As always, the devils in the details.

@@prostreetdino7946 thanks ,, I have a FXR 89 and I was thinking of a twin cam .. but it is very problematic and I like the EVO engine .. greetings

[@prostreetdino7946]

mco zpda I love the fxr! Kenny Boyce pro street is based abit on the fxr , and yes the evo motors are nice to work on and you can make a crap load of dependable power , would choose evo over twin cam definitely , if you like please check out my bike here on KZbin , it’s under my name if you feel like looking it up , nice to chat with you !

what compression?

[@adrianlancione7871]

Is this conversion still available

[@1967brokedude]

What cam?

[@allandrake4426]

100 HP at 4500 rpm would put the torque at that rpm at 116.7 ft lbs

[@megastick9324]

Nope...the torque levels off and begins to drop as HP continues to climb. Look at some HD Dyno sheets.

[@allandrake4426]

@@megastick9324 HP= tq x rpm / 5252 . 100 ft lbs @ 5252 RPM is 100 HP. Numbers don't lie, just sayin. 100 ft lbs at 4500 rpm is 85.7 hp.
