One might run that cam with a +4 degree crank gear and enjoy a little more Tq. in the mid range , on a stock motor ...just be sure to check all clearance's ..but then that would be a 777 ,with longer duration ....now that might be something !!!???

 

==================

Man,252/255 (IF THATS DEG DURATION @.05) is a ton of duration & overlap which is a bit too much cam for best perf if your motor has less then a minimum of 10.0 compression,it would work in that case but not optimal if comp is less then 10.0 at a minimum.

Boys love the convo and info but I ended up picking a different cam anyway. Thanks went with a recommendation from a local builder/buddy waiting to get the final tune numbers as we speak. Kuryakyn crusher 24d. Numbers should be somewhere like 104hp 108tq

 

Cams cams cams... We are all(well most) after that thumpity thumpity thump thump thumpity thump.. Science works way better than magic, You want the right package he first time, and all the available horse power for what you have, call Scott at Hillside!

 

Thanks for the kind words junglejoe!

Had a couple customers ask recently about this thread and the differences between the TW-999-6 and the TW-999-6A so I'm adding the info below from another relevant thread:

For reference the dyno chart below is a direct comparison of the Wood TW-999-6 and the TW-999-6A in the same motor on our 2015 Road Glide test bike. This motor is a 107" @ 10.75 compression with FM Level B CNC heads & FM E-Series 2/1 exhaust, tuned with Dynojet Power Vision. Note these runs were done a day apart.

 

Cyclerama .575 will push off more torque, as will a T-Man .625, and Wood 400.
No pork, without torque.

Ha! True all that....pork is good...torque even better.

 

The school of Hard Knocks and money pissed away comes into play here. Speaking in a general sense, who knowingly wants to buy a set of cams that leaves them with a useless bike below 3000 rpms? I am guessing no one wants to volunteer for that.


The 777's suck on a stock 103. I would suspect the 999-6a is the same. If a cam has an optimum compression range, post it in the advertised specs and move on.

 

I'd like to see the 117" Harley drop in cylinders matched to the 999-6A cams in a CVO with headwork.
