Dyno 107hp

111.8 Tq

Im interest in doing the mod - can you expand on etc etc - what did you start off with 96 or 103, dyna, softail? did you have your stock jugs rebored or did you purchase a kit etc?  

 

cheers

Streetglide 2012 originally 103. 

Rev perormance nikasil 107 10.5:1 flt ttops , tman 577 sm cam set. 4 degree advance( not such a good idea) 31 tooth front pulley, 137 tooth belt. 

SE cnc heads, SE adjustable P/rods, S/S premium lifters, fullsac header, crusher mellow slip ons, 

SERT, zippers chain tensioner, baisleys oil spring and valve. 

All in all not too bad!, 

less compression and another cam would have produced the same results earlier. JMO.

What cam would have change to ?? and what compression10:1?? or is the 10.5:1 too much compression for tman 577?

Thanks

Thanks for your input. I would consider several cam sets. 54s, 222s or perhaps Tman torqster. GMR has a successful grind as well. I would reduce my comp to 10.1 -10.25 . I think my exhaust etc is ok. As for the tune, well there is such a fine line between units. Possibly stay SERT or go the whole power vision thing. I would also consider Tman heads.
Don't get me wrong, I like what I have, but the intimidating idle and sound is not backed up with the performance, if you get my drift. I road today and it is all above 2500 rpm. Consequently , I am speeding and the Law here punishes speedsters.
Still, there is 1 hp for every cube. Just like the torque further to the left.
This must be an old argument. Overcaming !
