        Hi Guys


        So after fitted 13 18 Rs took for a few test runs,best i got was 73mph with full fuel take of fuel and two people. The top rpm was 8200, need to get it higher, so i was going to play with pumps, but have decided to fit new cams, new springs and new retainers.

        Hopefully will get to the 8400 rpm

        then on to bigger injectors and supercharges.

        Ill keep you all posted

        need to fit a couple of o2 sensors so going to have new exhaust spacers made to be 2 inches.

              So have two ET 70-145 chargers and two sets of VT1100 fuel injectors to fit, completing the PTO oil upgrade, lighting the fly wheels. Hoping for 80mph

              Any one else had this set up on a 430, any thing i should look out for?

                      Cool build, how did the hull feel at 73?

                      The older I get, the more I find myself fixing things that I knew I was doing correctly at the time.‚Äč

                        It was around 7 am (cold) dead flat water, it didn't jump around to much. I will need to make some trim tabs off the ride plate because once it starts porpoising it doesn't stop.

                        I also had a lot of pull to the right side on the steering, im hoping its just adjustment

                            Isn't not to bad if you not on full throttle just cruising , but if you are full throttle it doesn't last long lol

                              Hey all

                              Just a up date i have completed the head work on both engines, i have had the heads ported and new valve springs and retainers fitted super tec), also over sized valves Riva 1m+ and 2m+, lighten the flywheels and new custom ground cams.

                              So now working from home (covet 19) time to fit it all together and tune.
