I've seen the question asked a few times; because the Street doesn't have a tachometer, folks have asked what kind of RPM is the engine turning at various highway speeds...
Had a decently long trip today, mostly 65-85 mph, so I took the opportunity to figure it out using the tachometer on the Fuelpak FP3.
Basically, in top gear, a Street 750 is getting 15 mph for every 1,000 RPM.
That means 45 MPH = 3,000 RPM. 60 MPH = 4,000 RPM. 75 MPH = 5,000 RPM. 90 MPH = 6,000 RPM.
And each 5 mph takes about 350 RPM. So 45 MPH = 3,000 RPM, 50 MPH = about 3350, 55 MPH = about 3700, 60 MPH = 4,000.
Hope that helps anyone who was curious.
