Subject: [FlyRotary] Re: normalized
supercharger?
Jonathan,
Power (boost PSI) really does matter for normalization.
At 8000 ft air pressure is at 22.22 hg. It will talk about 3.75 psi of
boost to recover to 29.92. But you are correct. No need to work the spin the
SS any faster than necessary.

I'm not sure power really matters in the configuration we
are discussing... if you were going to boost, then yes it might be important,
but in normalizing situations having extra power is just wasted, cause you are
only maintaining ~30" manifold. The Whipple superchargers are also more
fragile, they require a very solid mounting due to the internal clearances of
the blower, if you do not have a good mounting the case will flex and the
screws will decide to become one with the housing, which is one failure mode I
do not want to even consider since it throws bits of the blower into the
engine.

Bobby,
before you pluck down the money for the Eaton, check out
the Whipple/KenneBell/Lysholm.
In the last 5.0-Mustang mag (sometimes I fall back to
old habits, sorry.... :) ), there was an advertisement for a KenneBell
setup as a direct replacement for the Eaton ( there was some factory offer
with a Eaton charger, probably from the Motorsports department...), which
claims more power/efficiency with the same setup (bolt in...)
I know that the Whipple is pricier than the Eaton, but
not that much!
