Re: S4 vs. Cadillac w/Northstar
i am not sure if the S4's peak torque of 257 lbft is at the
normal 1.8 bar max. boost or the 2.15 bar 15 second overboost mode.
various sources have said that the overboost is worth 14% increase
in torque, which would correspond to ~280 lbft if we assume that
the 257 is at 1.8 bars.
what is the max. boost for the '91 200TQ? if it is 1.8 bar then
i would think that the s4's 257 lbft would correspond to the
2.15 bar boost level, since there's little difference between
