this outting i did a little more port work in the intake and replaced almost the entire exaust. replaced the lemons colletors with 4/2/1 flowmaster collectors, h pipe 18" from primaries with 12" bullets empting into atmosphere at 35.5". the hole thing was a wash!!!! nada, nuttin hunny! at lest it didnt slow down. it did go a 1.46 once, best of the night was a 10.62 with a 1.49 at 126.44. looks like im done till cool weather. next set of upgrades should be a little more promising.

BTW...your car still kicks some a$$
