    Max HP

    what are the max HP numbers you have seen on 1500 or max boost if HP is not known

    That's impressive I will give you mine here by next month. I will be pushing the envelope. I'm going to run a 35r with a 2in header to 4 e85 nitrous, motec with 9.5's modified head,ported,lighted valves,cam etc at about 26 psi boost I be jumping for joy to hit 600 but realistically 500 range

    26 psi is no where close to 600hp
    unless your spraying 100+hp
    using e-85 you will need 2000cc injectors
    I have used bosch 110lbs and were done at 400hp on e-85 9.5:1

    Keep measuring psi to hp your on the right track well if I was done at 400 I would scrap my ski. Sit back you asked the question I'm answering I will be pushing a lot more than your calculations. No offense but people read magazines and see boost numbers and automatically equate to hp. In your test did you run a 2 inch I'd exhaust? Did your run 9.5's custom decked block,head crank, the best turbo setup you can put on a seadoo??? If not sit back relax and await my numbers all I said in my reply was what I expect and what I would be thrilled with. Yes e85 motec 1500cc custom on off headers,intake turbo and custom built motor by shrabber

    ya psi is not the best way to measure hp
    but with a well built systems you can get very close to real numbers
    I can bet your system will not do more than 12hp per lb
    and your not saying what your sprayn so I bet its just to spool that gt35

    If I was a hydro drag guy I would build a clutch for a big boost 2-step (anti-lag) launch like 5000rpm @15psi range

    So that 312 hp being my ski s stock 255 stop while you are ahead your looking foolish I'm done you have shown me your knowledge good luck oh one more thing you ran 9.5 I'm sure you know I have not measured one set of cp 9.5's that actually made 9.5:1 remember that's what there capable of but the conditions got to be right deck,head flow etc. my latest build was blueprinted as best that we could do in house. We custom decked our block,head and still could not get 9.5:1

    312 (boost)+ 200(motor) = 512
