well i got 2 times.. its a 3.5 with dunlop sport 8000's and i drop a tenth with the bfgoodrich g-force t/a drag radials i got.. so a 3.4.. it feels like riding on the street though... and it blew my transmission like i said... the motors got 9 grand in it.. when i payed 2900 for the car when i bought it... time and money i spend its good to get results even if everyone and their mom talks crap about crossfire...
