F-2: Inducer 4.50" Exducer 6.75"
for reference
F-3A-121: Inducer 4.76" Exducer 6.25"
Have experience with a F-2 on a 540 BBC and it has huge capacity. 1108 hp at 14 psi on 91 octane with very conservative tune.

So this seems to confirm my belief that the F1-X will outperform the F1-R but does not meet F2 standards as it just isnt big enough blower to keep up with the F2. Im hoping to really push an F2 to its limits and see what it can really do on race gas with some nitrous.
