Right now it has a bone stock internal 5.0L 1989 928 S4 motor with headers and a full mandrel bent 2.5" exhaust with only two straight through mufflers.....running totally stock brains....no chips, nothing....
The last dyno was 304whp 291 worque on a mustang dyno with AFR's running rich at 11.0 up top....past 4000rpm the AFR just gets richer and richer until about 5500rpm where it levels out at about 11.0..... I do plan on doing some fine tuning to get the AFR's more in line and should pickup 20whp or so....
