Nice, I see your running a 502. What the size and the speed now?
Right now, as it is in the photo with the
CMI headers etc., as of last week with
a Bravo 1 four-blade 26 prop, 69.7 on
GPS at 4,700 RPM. I am going to try and
increase the HP enough to get 5,100
RPM with the same prop. How much
HP does it take to gain 400 RPM? I'm
guessing 60 HP.
I decided against supercharging because
it is out of my budget to spend 8-10
thousand to gain 12 MPH! I'd rather do
it with raw cubic inches, normally
aspirated. Better heads, bigger cam etc.
Stock with a Mirage Plus 3 blade prop
it went 67 MPH at 4,800 RPM. With
that prop, 70 MPH at 5,200 hitting the
rev limiter. That is, with the CMI's and
Vortec flame arrestor installed.
