[QUOTE="tt335ci03cobra, post: 16331645, member: 68944"] Clearly 4th gear. You are correct that it was corrected with sae j607. The difference is saej349 is 77° iirc. Do you want to also speculate or inform the audience of why the computer likely richened out the car to 10/1 af ratio? No? They didn’t set up an air blower in front of the car. That motor will eat air at a very high level when attempting to travel 140+ mph in 4th gear wot. Guaranteed that if the computer could read higher o2 count it would have been a better ratio. Ford isn’t going to set the car for 10.0 at wot with optimal o2 readings. It probably can put down 720whp with a 10.6 to 10.75 a/f ratio. They should redo the pulls with 2-3 air blowers from Home Depot pointed at the grill. My turbo cobra doesn’t like dyno pulls without the air assistors to the tune of 40-50 whp. A car at speed in real life can suck in all the air it needs. [/QUOTE]
