I installed the Vortec flame arrestor and
CMI elbow tops last summer. Gained 3
MPH and 300 RPM. Plan on going to an
adjustable fuel pressure regulator and
reprogrammed ECU by Arizona Speed &
Marine so I can turn a Bravo 1 26 pitch
4 blade to 5,100 RPM (hope to anyway)
for 75 MPH.
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.
Early last year I wanted to buy a yellow Scarab II with twin 525SC's but Karen wanted a boat with purple on it. There was a really hot Scarab II for sale in Flower Mound Texas that was perfect. I hated to pass on that one. IT would have meant NO MONTLY PAYMENT if I had bought that boat.
No that is not my boat, but I would love to have that. My outlaw is a 25 and has the graphics like the one in my avatar, but with red black and yellow. I still need to take some new pics, because I erased them all off my digital, hopefully get the pics done this week sometime.
