Jesus Scott.... I couldn't imagine 175 HP on the road... I'd probably have to run M/T 29x16 on the back. Damn Scary....

Agreed!!! Heck I have no traction as it is now... and I am far from 175.. but I would be willing to try one out and see if I like it!

It's all in the cam profile, and when and where the power hits. My HP is set up so the daily driven/around town/freeway chores are actually pretty mild, and EZ to ride. Need to get serious? it's all upstairs, ready on demand, when you want to go there.

IME stock heads won't go any better than 100hp. Stock throttle body is somewhere around 115hp. A 120/120 engine isn't hard or considered max effort.
My current set-up has stock heads and throttle body and it made 115hp/123tq. 110ci, 999-6A's, 10.5's, S&S crank, oil pump and cam plate and a Bassani Road Rage. Is my next step heads and throttle body???.....absolutely. I just wanted to put it out there that you can make great power with stock heads.

What 110 kit did you use? Pardon my lack of knowledge but what are 999-6A's
I'm assuming the 10.5's is the CR? What tuner are you using?
Thanks

I haven't seen it all and will keep the conservative numbers when talking with customers about their expectations.
