“Yeah, I used to routinely pull 10.8s @ 135 or so in my 928.”
Get real. The 928 was lucky to pull in the 14’s.
used 89 928s4 +supercharger + intercooler + head gasket + 1 bar + ems + exhaust + 18x11 rears + aluminum artiste + shop time == $80k == 562 wheel hp dyno-ed. Everything else stock or stock-alike, but I kept breaking torque tubes. And fretted over the cylinder walls. The transaxle never complained a bit.
Probably never gonna do that again. but it was fun while it lasted (ie until my ex-wife found out how much it cost)
