POWER
- Best guestimate based on a casual diagnostic dyno run and several
experienced drivers is in the 275-300 bhp range at 9.5psi
PERFORMANCE: STRAIGHT LINE
- 0-60: Low 5's @ 7psi (Cartech Spec - verified by a street contest or two)
- 40-70 (3rd gear): 3.9 sec @ 6psi, and 3.6 sec at 9psi (observed).
- 1/4 mile: 13.5 consistently observed with experienced driver,
non-ported engine, and broken LSD. Driver said car would not
hook up, and estimated "the 12s" if the LSD was fixed.
PERFORMANCE: TOP SPEED
- However fast the thing goes before a.) the engine grenades from
overboost or b.) the aerodynamics of the car take on the
characteristics of a hovercraft.
PERFORMANCE: LATERAL
- Reasonable: I can generally run with "Super Stock" 3rd gens if
they have average drivers, but can't keep up with the two national
class 3rd gen drivers in the area.
