What gear did they do the pull in 3rd or 4th? I would assume it was 4th gear, but the AFR looks damn good to me except for when they massed the gas at lower RPM, but that could be relative to the gear they were in as well, to a certain point any way, great numbers though, I am sure that mine is only 175 HP and 200 FT LBs LOL

Good question Mike, I'm almost sure it was in 3rd.

That's about what I'd expect from a T56 car. Get the AFR and timing dialed in and you'll probably pick up 15. Headers would give you another 15-20 on top of that.

Ideal AFR is usually 12.8-13.2.

If you look on the A/F graph on the bottom of the dyno sheet, they have a red dotted line at about 13:1 - to give you the "optimum" for reference.

I had to do a little refresher, while 14.7 is stoich for gasoline, under WOT it needs to be what JZ posted.

Dyno's are usefull in determining what works or working better.
