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

i barely got 12 pounds out of a B1 @ 8500 rpm's thru a fb type 14 I/C.. @8600 rpm's we got 12 pounds.

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.

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