on my buddies 99 M3
anyways stock the lil ol 3.2 I6 made 205/225, added a dinan vortech supercharger(6.5-7.5 psi) and a corsa catback.
spun the rollers today for 300/260 on the same dyno he used before with very similar weather.
the S52 engine runs 10.8:1 compression, low boost, 91 octane, no knock retard. i am impressed.
