i went 12.64 with posi port
But that was with full weight (4600) slipping tranny and no sticky tires. Going again in mid october hoping for some 12.2x's or so all stock motor just bolt ons. Factory wheels etc but i know there are many many that are faster.
I'm in the very early stages of building mine up running strictly an eaton blower... hoping to get into the low 12s soon and as soon I go built and turn the wick up and spin the crap out of this sucker and stay in one peice im going to shoot for the record some time next year.
hell with what JJ has been doing with the eaton on lower boost levels I may see what he can do for me as far as putting a combo together
I ran 11.98 with my Eaton @ full weight years ago on my race tune, 10#/2.9" (stock) upper.
I ran 11.98 again this summer with the same motor, trans, tires/wheels, etc. & still full weight but this time it was on my low boost early shifting 90 octane winter tune (4#/3.5" pullies). Only big difference was the blower swap & L/T's instead of shorty headers. A lot less boost and a lot less timing too with a much fatter AFR.
