hi

i was wondering how low i can go in thw 1/4 mile in a ported S4 turbo? my best time in my 1st gen rx7 is 14.19@96 mph with completelly stock S4 turbo in a stock block gslse engine. i have a SP S4 engine and i heavelly ported the S4 turbo so (i hope) wont make boost creep and i wanna know if i can do at lease mid to low 13's with this turbo. thanks

 

my cuz ran 12.4 with 75 shot of NOS with a stock s4 setup in a 1st gen with slicks...13.1 without NOS...that is a stock setup so for your ported turbo....should be nice...
