Very nice bike. What do you think it will put out, horsepower wise, once you complete the engine mods? What brand is the exhaust?

Well, my bike suspension and body work project is complete. She's kind of dirty in these pics. 'Just finished a 600 mile round trip to Florida. 'Sure rides nice.

More power is next. In the basement, waiting on me is an Andrews cam, a Mikuni Carb, Screamin' Eagle performance heads, 95 inch jugs, and Screamin' Eagle flat tops. 'Already have the Thunderheader and Dyna ignition on.

Fernando,
That's a Thunderheader exhaust. HP isn't up to what you liquid cooled fans are used to and probably never will be, but it is a torque monster.
Stock, these Twin Cams (TC 88 - 1450 cc) put out about 65 -67 horses and about 85 ft lbs of torque ... and that would be around 3000 rpm. There are a lot of grandiose predictions about what various combinations of engine upgrade will give back in those departments, but the plain fact is that an air-cooled engine simply does not have the inherent capability to remain reliable in the long term and get the kind of hp numbers a, say a Ducati, has. I am trying to build a reliable everyday rider, that runs the way the design is capable. These bikes are EPA'd so lean it is scary.
My redline is set at 6250 rpm. Factory is set at somewhere around 5500-5600 rpm. I have a selectable ignition upggrade.
When all is said and done, I expect somewhere around 100-110 ft lbs Tq and 80-85 Hp. The nice thing about the components I have chosen in my upgrade is a Tq curve that should jump up early (1800-2200) and stay up (5800+). When I get above 3500 rpm, I should see the hp gains. I ride different from most HD riders. In the first place I ride a lot. 11000 miles in the last 3 months. Secondly I like to spin it up. I NEVER let the engine get below 2000, once I've gotten through it the first time. 3000-4500 rpm is where I like to ride. That makes the "potato-potato-chucka-potato-potato" trademark HD V-twin sound a little hard to discern.
Oh, and I have a great big honkin' Mikuni HSR 45mm carb to include in the upgrade too. Take THAT EPA!
I realize these rpm numbers are close to idle warmup for you Duc riders ... 8)
