    does anyone have data on the boost levels at various rpm's?

    so i scrapped the idea of using a sea-doo charger on my old 4-wheeler, but am building up a samurai with a 1.3L motor. i know guys are safely running up to about 10 psi on relatively stock motors. since i'm going to have to get creative with driving the charger, i'd like to know what kind of boost levels i can expect to get at various rpm's with anything from a stock 215 charger on up. one set of gears i can use will spin the charger at 38,520 rpm max. a sea-doo revving to 8200 rpm spins it at 44,587.5 rpm (87 teeth drive gear / 16 teeth SC gear). if i'm missing something in how i'm figuring this, please advise. i'm guessing that i'll get a few pounds out of a stock 215 charger with that low of charger rpm since i heard there really isn't much boost below 6k. any info would be greatly appreciated.

    If you ran a bigger wheel charger the less RPMS
    you could run ,to get the boost level your looking at with your gears.

    that's what i'm wondering about. i'd like to get more info about what the different chargers put out at different rpm's to see what would be the best route to go. either i get more creative with driving the stock 215 charger, or i get a higher boost charger. i was thinking about starting out with a setup that has way more boost than i need, then use pulleys to dial it down to a safe level.
