Last Sunday we got together with a good friend and visited Mack Motorsports in our hometown to see how much power our cars are making. Since the owner is a BMW guy and his Facebook post read "ST Dyno Day", we concluded that it was "Single Turbo Dyno Day". Even though we intended to see some heavily modified BMWs, we arrived at a shop full of Ford Focus and Fiestas
Because we got there a little late, we had to wait until we were able to get on the roller. For those who might ask, I'm not aware of the barometric pressure or humidity during testing. However, I can tell you that it was fairly hot for March (low 80s) and we are at sea level.
My car is a 2017 340i with an Activ-8 tune, Dinan CF CAI and Dinan Mid-pipe. RWD, 8 spd ZF. No E85, just Shell V-Power (93 oct).
My friend's beautiful 2013 335is coupe (with 3 pedals), has a flash tune and downpipes.
Seemed like most cars were reading high torque numbers and low hp so I didn't expect much. There was another guy that ran an N55 335i cv (auto) with JB4, downpipe and a little E85. He made 320 WHP and 370 lb ft TQ.
We made two pulls each, his best was 332 WHP and 370 lb ft TQ.
To both our surprises, my car made 377 WHP and 372 lb ft TQ.
This platform keeps exceeding my expectations. Two days before, cruising to the Porsche Werks reunion in Amelia Island on the ECO PRO mode (sorry, I know it's a sin) it averaged 39.4 mpg.
The car ran a 13.01 1/4 mile at 107.86 mph completely stock. I can't wait to go back to the track and see what it can do now. I will need a new set of tires before going though, my S001 RFTs are at 4/32" at the rear and I suspect they will not be hooking the way they did last time...
