M Roadster ESS Supercharger Results
06/14/09 16:41, by GoodSpeed, Categories: Uncategorized, New Products, Forced Induction , Tags: az dyno, bmw, dyno tuning, e46, ess tuning, m3, supercharger GoodSpeed Performance Lab completes another ESS Supercharger. This one lives in the bay area and you may see him on the track. He frequents Infineon Raceway, Thunder Hill and Laguna Seca.
This car came to us with Dinan throttle bodies and cold air intake. The baseline on the Maha Dyno was 345.2hp at 7900rpm and 280tq at 5400rpm on 91 octane.
On this kit ESS uses a clutched charger. This enables the charger to 'free wheel' at cursing speeds as to minimize parasitic loss.
The air to air intercooler fits behind the bumper cover without cutting.
A Setrab Oil Cooler is included on the M Coupe and Roadster.
And now for the results;
Horsepower is increased to 481.7hp at 8200rpm up 136.5hp
Torque is up to 340.7 that's up by 60.ftlb

And to top it all off, there was an unplanned beneft, I now get 15-20 % improved gas mileage, how can you beat that? The supercharger will pay for itself some time this centrury.
I would highly recommend these guys to anyone that is particular about how work is done. A well pleased customer!
