Our friends at COBB Tuning provided us with some fantastic in-depth data from its stock baseline dyno results of its 2015 Mustang EcoBoost model.
COBB utilized a Mustang MD500-SE load bearing dyno using a freshly performed parasitic loss calibration specific to this vehicle.
Some interesting things that COBB learned from its dyno runs:
“A full 4th gear sweep is extremely long and painful for a stock car. The sweep starts at ~30mph and ends at 133mph! During that time a lot is going on. For one, the car is making a phenomenal amount of torque right of the bat at a relatively low boost level. The torque curve is flat as a rock for about 2500rpm, when all hell breaks loose with heat management. This is when the power tanks and you see massive losses. Heat management strategies are in place to protect the engine and are typically a bit overkill due to inaccurate models. We’ll be doing some more research and testing on the validity of the recorded values to help uncork some of the power robbed from these functions.”
Boost – Start 13.1psi, Max 20.1psi, Redline 12.56psi
AFR – Great up until overtemp conditions, then sinks as low as 9.9:1!
ECT – Start 191F, End 226.5F
Charge Air Temp – Start 100.1F, End 184F
Oil Temp – Start 189.4F, End 205.2F
Trans Oil Temp – Start 175F, End 194.4F
Ign Timing Correction – Removed up to -2.5 degrees
