I have a 1986 grand national with the following "mods". Aftermarket CAI 42lbs injectors with turbotweak chip hot wire kit with 340 Walbro pump alkycontrol cat back exhaust and rjc throttle body plate. I think that is all. I am looking for a fun driver but I wanna have a 12sec 1/4 time. I planned on buying a downpipe next but I am unsure so my question is what is the recipe to have a 12sec grand national with the mods I already have what else would I need to get me in the 12sec 1/4. I ran my car once at the track when it was close to stock and ran a 14.1.
