Supposedly BBlades has a tune for the Mirage+ that’s good for a few mph, but you’re right where you should be with a stock set up.

The race fuel is probably costing you a couple mph. You should run 87 octane.

What prop and RPM? Assuming you're pulling close to 5000 rpm?

Dakotabo 09-26-2020 04:53 AM

4800 rpm, mirage plus prop 27 p. I actually hit 68.1 mph the other day on the gps.

My best performance was with a 23 Mirage Plus turned up a bit. 27 was to much prop for mine

68 on gps on my 99 272 502, with 23M+ labbed with 496HO manifolds.
