Riva s3 vs. Rude
Obviously we all know the Rude is much better, I would like to know what boost each supercharger ypically puts out at 8100 rpm....with riva rear air and xs intercooler...I realize that an ECU is needed to gain their full potential but I am curious about 8100 rpm boost...could 80 mph be acheived without an ECU?

Your answer lies here:

RXP244 went 79.7 with the stock ECU.
I'm trying to see how fast you can go with the stock intercooler, ECM, and injectors. . . 74.0 so far.
I'd personally like to know how much boost all of them make at 8100 rpm, including the Les Cooke wheels, Rude charger, Riva S2 and S3, and Rotax variants.

On an engine running 8100 RPM's
stock SC 6.5
Riva Vortech 8
Rotax Racing 9+
Les Cooke A kit 9+

If the stage 3 sc puts out 11psi at 8100rpm what do you think it will put out my gtx rev limit of 7600rpm?

Yes, where do the B kit and new RR 'spacer' wheel fit in at 8100 RPMs
