    Side note overboost I wouldn’t mess with the lucky 13 cone and waste your money boring your pump and steering nozzle and repitching your impeller

    With a 87mm nozzle and the right combo of spacers , you can make a high 80s ski top out at 74. I too have given up on the l13 cone and going back to stock venturi and nozzle. Seems to me big gains with a 159 prop not so much with a 161.

    Im going to water test tomorrow.....will do stock cone after i see what happens....found SC slip was set at 12lbs, so I set it to 16lbs, and put in a new set of plugs. will see if this helps any....may do back to back run with l13 cone and with out.

    made some good progress today.....I feel like one the three things corrected the problem ( if not a combo of the 3 ) , oil level was a little high( lowered it to less than 1/2 way up the bends)...check SC slip, was low so set it to 16ft lbs.....and new set plugs..results 81 mph @ 8100-8200 RPM @ 14.4 PSI boost, on stock prop ...Lucky 13 cone (no spacers) with 5 bars of fuel...going to remove l13 cone to gain some rpm and maybe depitch stock prop and see what that gets me.

    just wished more people on here would follow up on results...when searching , found lots of dead ends .....good luck to those that find this later and helpful

    Please post your results with the stock cone.

    What are the AFR's? I've found that outerwear hurts RPM.

    Nice took mine out Saturday without my lucky 13 cone and back on my 13/18 impeller hit 81 at 8500 rpm but the big improvement was on my 660 time nearly shaved off half a second
