i beat a stock automatic 04 gt with an x pipe with everything in my signature except the performer rpm intake and the throttle body, last night i raced my friend in his 96gt with a 99 motor swap, 3.73 gears, 5 speed, headers, midpipe, mufflers, underdrive pulleys, cold air, and he beat me by 1 car till 115 where we stopped, we raced from a dig and from multiple rolls and we always stayed dead even till 100 and then he'd pull a bit, i also raced my buddy in his 04 GT, automatic, 3.73 gears, chip, x pipe, throttle body, mass air, ported intake plenum,
k & n, and we were dead even every race, if the 5 speed gt u are racing does not have gears you might be able to take him for awhile but top end he could pass, do you manually shift ur car 1st, 2nd, drive?
