Best recipe for a 12sec 1/4

[turbo nasty]

With what you have listed...I didnt see fuel psi reg...make sure the fuel psi is rising properly to boost. Turn boost to 22 PSI (chip burned for it), Drag radials at 19 psi, leave on foot brake where needle is just coming off 0 and 12's all day with car in perfect mechanical condition. i.e. - suspension not wore out, trans not flare shifting, not running hot, igntion good, fuel pump, etc etc.

What everybody else said lol 22-23lbs on DR's and your there dude! Stay safe and watch the KR.

Way way... back in the day my stock GN went 14.0 first time at the track on 16lbs of boost on street tires. A pair of DR's later, good race fuel and 22lbs of boost (the car already had a 340 pump and a Red's chip) went 12.5's. Blew right past the 13's

Which is actually more desirable, TA49 or 44? I have the TA49.

The 44 flows a tad better, people choose the 49 to keep it stock appearing if that's your thing.
