I picked up my 87 GN last November for 4500 and have invested another 3000.00 which included a trans rebuild and new powermaster. I made 3 passes all stock (before trans rebuild),15lbs bst; 14.8 @ 94 mph 2.4 60ft. After trans rebuild, DP, AFPR, stock chip,ET Streets, open dump, sunoco 94; 13.6@98mph 2.0 60ft. Then I added walbro340, rear springs, hooker exhaust, thrasher chip, c16; 13.36@101 1.9560ft. I am still learning to launch this beast and need to upgrade the brakes but I think I should be able into the 12's with more boost, better launch and a different chip. My total investment is under 8000 and this car has 170k on the speedo.
