Not quite right, a stock 3.2L M3 is good for about 200HP at the real wheels... if the 328i Supercharger is putting out 245HP at the wheel your looking at +85HP (give or take a few) thats very impressive.And more importantly way more torque...then stock or a M3.
Typical drive line loss is 17% so multipuly the factory HP numbers by .83 to get a number closer to the rear wheel.
: I sent ESS an email and asked if they had any dyno runs that can show the claimed +100 hp increase at the very mild 6lbs of boost pressure.
: If they could, I'd get one immediately. It would be an amazing bargain for that much power (~300 hp).
: Sadly, the chart they sent listed a much-more-to-be-expected +50 hp.
: If you've driven an M3, that's what you can have in your stock 328 by getting this s/c.
: See the results for yourself, as soon as it gets posted.
