Supercharger wheel for 260

[Scooterman2025]

Hi I was wondering what?s the best wheel to get for supercharger for 260 hp seadoo and can I run it with just a rising rate fuel pressure regulator and pump or do I need bigger injectors thanks

I am running a drop in wheel with no other fuel mods.

We have a wheel that does 16 psi at 8700 RPM. Yes, you should run larger injectors with a wheel making that much boost.

You only need a fuel pressure regulator if your stock one is having issues. Rising rate is really only needed for high boost applications where the boost pressure is so high it pushes back on the injectors enough that it prevents proper fuel atomization. This is for high boost turbo setups.

You would want the VT1100 injectors.

The wheel won't get much gains, you'd be better off doing camshaft and titanium retainers

Does the stock pump change pressure or does it stay at a constant pressure

[activejetsport]

Pre-325 models use static fuel pressure of 58 psi. It will drop slightly at high RPM but that is normal and you account for that during tuning.

A wheel will give you a significant gain over stock. The normal upgrade process is a wheel and then, if you want more, a cam.

You're referring to your 260 fuel pump, which is operating at 56 psi of pressure. I recommend changing it to AEM 340, which is like $98, and a relay from https://brtparts.store/collections/f...55-230-260-300
