Here is a 120R dyno chart sent to me from Al at Hot Rod Harley Davidsons, located in the great state of Michigan.
Al is a top notch service and dyno tech who I have worked with for a few years.
The 120R crate engine was installed in a customers 09 Street Glide with a Fullsac "B" X Pipe, Rinehart mufflers and HD Heavy Breather AC.
Typicall smooth X Pipe TQ curve with almost 1.1 HP per cube! Not bad for something that came from an HD catalog.
I'd really like to see one of these 120Rs with a little less compression, smaller cam profile, and the TQ line clearing 125 at 2500.
That would be a Touring motor.
