Supercharger Boost Comparision

[RobbieMWD]

I was wondering if someone could compare the different superchargers boost at 8100 rpms.

Stock
Green Charger
X Model
Rude Charger
Riva Pro-Series SD
Riva Gen II
Rotax Racing Impeller
Piranha C

If there any other types or configurations I missed if you could please add.

I can tell you I get 13.5lbs boost at 8500 rpms on my ski. I have a RUDE.

Boost numbers will vary from ski to ski due to variances in set ups (intercoolers, etc) and differences in environments. How about i list weakest to strongest for you?





Stock
Riva Vortech (discontinued)
Green Charger, Rotax Racing, Riva Gen II, A kit impeller (all the same thing)
Riva Pro Series
X Model
X model with rotax racing impeller/spacer
Rude Charger & B kit
Piranha C

Thanks, that helps me out. I'm a NEWBIE, so I get confused with all the different configurations out there.

Where would you put the the A kit R sc impeller in that list

[ARNYGOLLOTT3]

All numbers are IMO @ 8100 rpm

Stock 7
Green Charger 9-10
X Model 10ish
Rude Charger/B-Kit 12+
Riva Pro-Series SD 10+
Riva Gen II 8
Rotax Racing Impeller 10ish

Piranha C 15+ @ 8500 when torqued right

Where does the non-X RR wheel with spacer fall? Better than pro-series and below Rude?

What do you mean about the C charger being torqued right can u elaborate? i have just upgraded from B to C CHARGER and still run stock ecu,is this charger more suited to aftermarket ecu? does anyone know approx boost figures at 8100 rpm of C charger? am going to run this weekend so would like to compare my figures thats all.The B charger was absolutely awesome so hoping C is even better but now wondering about stock ecu.
