Those are some pretty respectable numbers. How would you compare the side mount whipples to blowers? Sounds like that is a much better way to go. Also how does the pricing compare to that of a 250 or 420 mega blower?

getrdunn, dont know any thing about the other blowers compared to the whipples but my choice would be for the fuel injected set up because of the ability to tune and all around running. Will do STRIP cant wait to get them back in and start running and testing props any one have any idea of where i might end up prop wise. was turning 28p bravos 5400 @ 86 mph with 1.36 gears that was with 470 hp per side?? :)
