    Riva B-1 Boost at higher RPM?

    I did a search and couldn't find anything. I know Riva claims 11.5 psi at 7700 rpms but does anyone know what the boost is at higher rpm? they don't have any higher boost claims like other manufacturers and I haven't seen anything anywhere else on the forum with boost numbers over 8k
    Thanks

    Damn, thanks for the info. Someone else I know didn't get any higher boost either. Looks like I'm going with the low boost ET wheel

    theres another thread around here somewhere, where people where barely seeing 12 pounds either at around 8500 rpm's out of the B1

    i just installed a ET low boost wheel on my fz and man, what a differnce the prop is still not dialed in and it still out performs the B1 all around.

    I've seen as high as 13.1 coming out the hole with a max speed of 82.9 so far...this was done on no less than half a tank of fuel, going up river. Tach has recorded as high as 8640 if I remember correctly.

    305coco,
    Is there more or less s/c flutter with the ET low boost wheel compared to the B1?
