Check out another post on Interpreting Dyno Results for more details. The actual number isn’t too relevant as it will be different with varying dynos and conditions. Even if we were able to prevent the car from limiting power in AWD mode, the gains expressed as a percentage will be identical in either FWD or AWD mode. The best way to dyno the vehicle is in FWD mode with the RDU disconnected. When this is the case, the car actually “thinks” it is losing traction which results in it intentionally limiting power.
With the rollers spinning at a constant rate, and the vehicle trying to spin the front and rear wheels at different rates, things don’t mesh well. Keep in mind that the dyno rollers are linked front and back so they spin at the same rate. When the RDU is active (sending power to the rear wheels), it causes the rear wheels to spin faster than the front. This system is called the Rear Drive Unit or RDU. Instead, there is an electronically controlled clutch pack that sends a variable amount of power to the rear differential. The Focus RS does not have a center differential like other AWD vehicles in its class. When our baseline numbers for the Focus RS were first released, there was a lot of talk about them being inflated and even more concern surrounding the fact we dyno’d the vehicle in FWD instead of AWD mode. The below will be similar to the released Stage 1 Off The Shelf map that will come on the Accessport! After more time on our dyno here at COBB they were able to come up with a safe and reliable Stage1 calibration that still offers some healthy power gains.
Our engineering team learned a lot with their time on the RS in England. The Ford Focus RS is now supported! Check out this post for more details! June 30th – Preliminary Stage 1 Power Gains **Catback exhausts do not usually add power.By Kyle on Ford Focus RS Power Gains and Development * One step colder spark plugs are always recommended when tuning, an upgraded intake or filter can also be beneficial.
