what supercharger is this?

[Mrigor]

how can i tell what supercharger i have? i bought ski with upgrades
On the impeller it says "H" and "1 9 5" and approx diameter is 137-142mm





on the ski also so far i found 42 bosh injectors, and fuel pressure regulator. on the ecu it says rotex

Was there a spacer between the housing?

no spacer. what does the spacer add?

 

[red2blue]

Well....it would enable you to use a "taller" wheel of the same dia. Thereby getting a higher boost wheel for minimal cost...ie..just have to buy the wheel and spacer while using old housing and shaft instead of buying a complete sc.

What other mods are on the ski?

What are your numbers?....gps'd mph and rpm.

no numbers yet, i just bought it. engine was flooded with water. I am rebuilding it now.

i dont know what exact mods are on the jet, so far i found:
42lb bosh injectors
fuel pressure regulator
riva intake, intercooler
riva exhaust through hull
the x supercharger (assumming)
Block off and Hull extender

i am not sure where else to look for mods, how can i tell what pump impeller i have? and what intake grate etc... i am guessing ECU is stock, it says ROTOX on it... i am not sure how to check either.

You probably need to upgrade your injectors (50lb) for that blower, as well as a flashed ecu (which you may also have). Or you run a risk of seriously leaning out. Nice parts, If you want to part with the blower I have a like new stocker (2012 clutch washers, very clean and very tight) that I would trade with some quid!

i looked at the plugs, they dont seem to be lean, they are nice oily. i would say its running on the rich side by the spark plugs

Oily? This is a four stroke, only reason they should be oily is from fogging oil?

not oily black i ment. but i will get my ecu checked. I have to find a place here locally. unless anyone know how to check without a scan tool

I noticed on pictures of the supercharger wheel there is markings. mine says "H", i have seen "R", "K", "F" etc.. what do they mean?

Let's start at the beginning....

What ski, yr and model are we talking about?

Next would be pics of grate, prop, ect.

If that's an x wheel then 42's are fine for that set up. You sure it don't say rotax on that ecu? Rotax does make a racing version of their ecu's...differences from stock will require valve train improvements.

2007 RXP 215 . I will make pics tomorrow of the grate, and prop. It says "Rotax" on the ecu. How can i check if its racing version? My head is off right now, how can i check of the valve train is stock or not?

It would say racing only...so I'd forget the valve train improvements. Curious...where'd you get the ski? No previous owner to ask these questions?

you have mail

i bought the ski from guy, that bought it of someone else then flooded the engine with water. he sold it to me with blown engine.

 

[Mrigor]

does not say racing only. just rotex
