I have the TW-7H in my 103" 2007 Ultra. I got 110 HP and 122 TQ before I tuned the exhaust. That was also before I installed nitrous.
I am very happy with them. Starting TQ of 80 @ 2000 RPM... Starting HP of 33 @ 2000 RPM

Max TQ of 122 @ 3800 RPM...Max HP of 110 @ 5500 RPM
103+ ported heads and pistons, 57mm T/B roller rockers, SERT,


I have the Zippers 575 in my wife's 95". It had 99 HP and 103 TQ
It seems to really pull after 3500 RPM. I will be swapping them for a set of TW-8 cam an a couple of weeks.

The SE 575 cam is great. Maybe the S&S 600 cam.

VRYQUIK , You seem to know how to get the most from a harley engine, have you ever played with a sportser, if so what did you do? Have you ever seen nitrous on a sporty?

[09 blackthunder]

That type of power on a sporty would be insane

I've built a couple of Sportster engines. I prefer late model EFI Twin Cam engines, only because we build so many.

I'm currently building a 103" motor on a 2003 Softail Standard that should be pretty impressive, especially if I can talk the customer into installing nitrous. I'm using a TW-6 cam in this build.

I haven't shot nitrous on a Sporty. That would be interesting!

I built a Sportster engine for the guys girlfriend that has the Standard that I'm building. I'll try to see what all that we did and if he had it dynoed. I'll get back to ya.

I hear good things about the TW-6 cam. I'd be interested in seeing how it does.

I would take either; which one you do not use!!
