We are now putting on a Raylar BCK 103 Kit
(www.raylarengine.com)
This will add another 100 HP
I will keep you informed about the results

What was the original top speed before the CMI's?

(the impress your passengers guage reads 72 mph though)
I was dissapointed until I realized everyone is not as fast
as they say. I know alot of people claim their boat ran 68 or 70 but must hold back a couple hundred rpm whenever we run accross the lake.

Re: 275 with 496 HO and bravo 3
Raylar kit is on
with the bravo 3 drive and 28 `props boat is hitting rev limiter very quick at GPS 71 MPH @ 5150 RPM
Boat now behaves like a dragster and also sounds like one (the real good sound comes from the raylar kit - the CMI just add a little more sound)
I have never seen or driven a boat like this ,
time to plane less than half time
If you push the throttles down at 3000 - it takes just the blink of an eye to jump to 4500
extreme quick throttle response
With a bravo 1 the boat will run even faster , but the owner now prefers the bravo 3 setup
next we will reprogramm the ECU for a higher rev limiter to gain some more top end speed
By now owner is 120 % satisfied with his new raylar engine

it was so low on gas, he ran out on the way home and had to get a tow
