Had the Black Pearl dyno'd today on a Dynocom 5000 2wd chassis dyno (Mustang clone I'm told). Attached below is the readout. The a/f is super pig rich. .7/.8 Lambda, 10.3/11.7 stoich. That explains why I'm getting what I think is bad city/frwy mileage for the motor combo. I'm not going to start a flame war on the tuner. He has a good reputation and many here have used his tunes. It's clearly a safe tune. I will email him for an update. However, I'm certain a ton of power is being left on the table. The O2 sensor was placed just before the cat in a bung I had installed some time ago. Motor mods are as follows:
Stock 5.9 short block, 210x cam with 1.7 rockers netting .540 lift. M1 with 55mm F&B throttle body, massaged oem heads, headers, MSD ignition, electric radiator fans, MSaine 2800 TC, TransGo kit, 4:56 gears on a Detroit locker.
I was looking for near 300 rwhp to the wheels. So, will getting the a/f corrected get me near that 300 rwhp mark? Also, In your opinions, what kind of power should I be making with this motor combo?
Your thoughts, opinions, suggestions, flames, bashing's and insults are encouraged and welcomed. Thanks in advance.
