Very interesting!
I just ran mine on the dyno last Sunday too. While I was there I learned from the dyno tech that turbo cars should run about 11.5 A/F ratio for max HP...
That's something I never knew... Before going to the dyno I always thought you should always shoot for 14.7 (perfect stoichiometric ratio) but no, not on a turbo'd engine he said. 11.5 is apparently the magic number to seek for max power...
And I always thought the magic numbers were 12.7 to 12.9:1 for peak torque and 13.0 to 13.2:1 for maximum horsepower.
Well, anyway, like I said, very interesting!
You DO learn something everyday...
Great info tip on the MAF gutting tho!
*EDIT* Ohh, I forgot to post my dyno pic (embarrassing HP but posted anyway so you can see my A/F ratios)
