My GN was running 11.50s all day long with not much done to it.
TE-62, Dutt neck IC, 3400 stall, some trans work (not much, just basic stuff), Walbro 255 w/ MSD50s, ATR bar, W/B, just your basic average street car. Not much in there rear, just a posi/axle upgrade due to clutch failure in the G80. Boxed stock LCAs and stock uppers. Usually goes low 1.6 60's. Roughly 27psi on alcohol.
This was with a stock, unopened motor with valve springs and a timing chain. It ran great and I drove it everywhere.
Freshened the motor and added ported irons and a roller cam, and it went 10.97@123. Still on the TE-62, Dutt neck, and 3400 stall ProTorque. Still stock intake/plenum/TB. My car doesn't have many "cool guy" parts. And I like it that way.
