M1 vs RPM Airgap - SB ??

[388dart]

Does anyone have some timeslip info on whether either one of these manifolds is better than the other - preferably operating on a race type small block mopar engine in the range of 3-6500rpm
I have the Airgap now and changing to the M1 single plane makes quit a difference in my simulator program (both torque and hp) - but reality may be a different story.
thanks

FWIW, Every test I have seen comparing the Air-Gap to single plane manifolds it is as good or better up to 6500. It's only after 6500 that the single planes have an advantage.

Yep I say pull the torque down low from the dual plane. These engines dont exactly spin to the moon so a single plane isnt going to be the optimum if you ask me. I dont have any dyno or track numbers to back it up though.
