    Stan: JD 1 ran the "B" on a stocker with a prop and turned 75. Les Cooke told me 3-5, but that it really depended on your setup/conditions. Chances are the faster you run, the less the gain.

    The "B" kit s/c can be added to a completely stock ski with no ecu change or modification - provided it does not have any air intake modifications. For skis with more work done, you need to get Les' secondary fuel pump & fuel controller -$540 shipped (or something from RR or Nils to match).

    My "B" is due here this week, so hopefully I will be posting some new numbers on the weekend.

    With a secondary fuel pump , it pretty much throws more fuel in right ?

    Does it change your gas consumption by a good bit ?
    Am I going to be filling up every hour of riding ?

    I don't know about every hour, but I'm sure mileage will suffer. As per Les, his pump will pick up where the stock pump leaves off and can provide up to 100psi of pressure. I think the stock runs @ 60; but don't quote me.

    Any time you increase performance you increase fuel consumption.

    Stan, I have an A kit and the reflashed RR ECU, but the ice is off the lake here just this weekend. I have a bit of work to do and will not be in the water for another month I imagine ...

    What is your setup and your latest speeds?

    Brendan, does Les' fuel pump fit in the tank? Does it replace the stock fuel pump? Any info on how/where & how difficult an install it is?

    Vern: Supposedly the pump will fit in the hull (somewhere) and runs along with the oem pump. He said the pump is triggered by the boost level, which will now be measured from the old bov line. He does not recommend a bov w/ the big s/c. He said the big s/c needs the brake effect of the back pressure to reduce wear. My kit just arrived so i will look tonight for fitment. Les said there is a complete set of directions though.

    OK, that sounds easier than replacing the in tank stock fuel pump! Looking forward to your results!!

    Interesting on the BOV ... what Les said is exactly what a number of us have been saying for quite awhile. The back pressure REDUCES clutch wear .... funny, all the experts EXCEPT RIVA (who sells them) are AGAINST the BOV? I took mine off and blocked the hose the day I installed my RR IC, did not like it. Mark U, Franco D, and Les all don't recommend them, good to hear somewhat of a consensus.
