You can’t get traction cause you have an auto trans and u smash the pedal… also the 3.8sc with mods has little traction because of its tq. Its been proven with proper cooling the smaller pulley shows hp and mainly tq gains over larger pulleys with increased timing. GTP and redlines are similar only on the fact that they are gm’s and boosted by eaton blowers…
oh and fyi a gm stage II kit nets you 15psi. Stock we run 12.5. So anything past 15psi just means fun.
