Top speed at that track for us is about 90-95mph, 100 would be stretching it even in the draft (which I was) with the ratio I was running but I'll say at least 90. Turning 500 rpm less with a taller ratio was 97 in the draft entering turn 10 at Sears Point. Calculated RPM w/ gear ratio and circumference of the rear tires not accounting for any minute expansion that might occur. The rear tires are not slipping at top speed so it's a pretty accurate idea. Certainly doesnt always look like it though :)
