Raptor SCrew Dyno Results

My buddies were having a dyno day at their shop the other day. Shaun called me up and said they wanted to strap the Raptor down and get a few details on the factory tune. We had to run it in 3rd gear because we hit the speed limiter in 4th. She put down 336 RWHP and 343 RWTQ... a little better than I was expecting. Here's my typical crappy cell phone video...

That isn't bad at all for factory vehicle I don't think. Thanks for sharing the info on factory tune.

Did you run on premium?

What Air/Fuel ratio did it run? Did they do any part throttle runs? Just curious what it is set at in closed loop.

It was about half 89 and half 91. Call it 90 octane.

The richest A/F showed 11.7 but it was mostly in the low 12 range. This was just a tailpipe O2 so it was a little slow to register. We didn't bother hooking up to the rear O2 sensor because SCT doesn't support the 6.2 yet. They told Shaun that they did but he couldn't pull anything up when he plugged in the computer code.
