Jetski superchargers

Dear Boosters,

i've been browsing the Forum looking at your marvelous results and intriguing experiments. Since i'm very much less than a beginner at designing and building an electric supercharger from scratch making use of a P2 and its necessary accessories, i thought of maybe trying to apply a jetski supercharger - like a readily and cheaply available sea-doo model. There could be a big advantage as no need arises how to source / machine the axle, as it comes complete, at possibly even lower prices (on ali) than a bare P2.

i was wondering if those are not feasible at first glimpse to you at all, since i found no entry investigating their potential in any threads (apologies if they were discussions i missed).

The factory models are restricted to ~8500RPM, which might not pair in an optimal way with the Holy Grail HW 70125 560KV, as its lowest RPM at 8s is twice as much. Although with aftermarket billet impellers (a Rotax for instance) the RPM limit might be lifted.

Could anyone please advise?
Thank you!
 
Pendulum Tuning in Australia was developing one using the Jetski blower with the overkill
LMT 3080.


Also DIY VIDEO channel shows a basic one using a 2kw brushless Vevor Scooter motor.


I know they make these superchargers suitable for upto 300hp. At a guess 5-6kw would probably be required to spin this for sufficient CFM for 300hp.
Rocket Surpass have a few cheap motors.
6S 5692 rated around 5.2kw - can run off 24v (12x 12V SLA) on a budget.
or
8S - 10S / 56112 rated at 7.3kw

A hobbywing Max 6 G2 8S with Bluetooth would be a perfect match for these motors.

As I don't think the Seedoo blower will draw the full 195A on the 8S motor.

Best of luck.
