MSV Question

[RD7]

Hi my first question on this site, I as lurking for  a long time on the old site and pleased to see it back.

Preparing to work on the heads for an air cooled RD 350 special race motor.

Peak power is targeted at the moment at 9000 RPM. Using Mitaka RZ 350 pistons (cast) with the rear tangs removed. Using Rods manufactured by Long.

The Heads will be pinned central to the bores.
The corrected compression ratio will be set 6.5:1. Running 95 or better octane.

The cylinders have been O ringed and looking to set the squish at 0.9mm (slightly more than 35 thou) at 14 degrees and 50% of bore area (9.4mm wide).

My best calculation/ measurement of the angle of divergence of the squish is 5 degrees.

Before anything is done I want to calculate the resulting MSV using TorqSoft.
I have in my notes a range of MSV of 15-22m/S for road racing but I didn't record he source.

Can anyone validate the range of MSV I have or more importantly give a more definitive MSV to go for?

Thanks
