The race cars you're reading about have high redlines because the
engines are built and set up for max power, which in small
displacement engines comes at the expense of low and mid range power
and torque. You really don't need or want to do this on a street
oriented engine. On a street or even a street/track car you want a
strong low end because that's where the engines going to operate most
of the time. After the initial bloom has worn off the newness of a
high revver (usually about 30 minutes!) you'll hate it. The car will
be hard to get moving and will be gutless. Trust me, BTDT.
As far as the oil systems are concerned, in a car that experience high
G loads you need to do everything you can to keep the oil pickup
submerged in oil so you don't loose oil pressure and/or run the
bearings dry. All sorts of bad things occur when that happen, all of
them expensive. That's one of the primary reason for the accumulators.
They maintain oil pressure for a short period of time if the oil pump
can't.
Bottom line, on a primarily street driven car you want low and mid
range torque, not high RPM horsepower, and if you have a properly
working stock oil pump, your pan is in good shape and the oil level is
where it should be you don't need to worry about an accumulator.
