How much horse on the Phazer II?
Top speed?
Top speed?
bought 56hp was the factory spec. With a little work and good fuel they can reliably make about 80 or so depending the dyno.

Back in the day I ran about 89 MPH (Speedo 96) at 1/4 mile radar runs. Won some, lost some. That was a "90" single piped, lake racer porting, 38 flat slides. All PSI work. This was also trail ridden in this form thousands of miles. Stock ones about 85 on speedo, high 70s radar. They really respond to a pipe. Just watch the jetting. No Wide open for miles with pipe. Gear it up one tooth on top. It really needs it. Doing this will actually help acceleration on this sled. At least on mine with the YP clutch. (Strange but true)
