RE: Speed density - going off tangent

'87 and '88 (49 state) Stangs were faster (stock) because the speed density
ran leaner. Make minor mods to increase air flow, the computer couldn't
compensate with more fuel so it leaned out a bit which makes more power.
Plus they didn't have a restrictive mass air meter in front of the throttle
body. I had an '88 ex-CHP car and it was the fastest stock car I've ever
driven. The mass air cars were pig rich at WOT.

Those days are gone.

designed to make
                 power, not be emmisions whatever. My friend has a 89 in
the high 12's and
                 he is running the stock computer. Whatever he does, the
car learns it in
                 about 5 miles and he gets faster. >>

                The speed density stangs were faster than the MAF controlled
stangs in stock
                and near stock trim.. '87 was a real quick year for the LX 5
spd stangs if my
                memory serves me correctly, and it was speed density
controlled .. didn't take
                much (if anything) to get them in the high 13s back then ..
