Your probably not gonna get to mid 12s with just a vortech if your npi.
NPI sucks real bad.
With a pi intake and a good amount of boost you should be able to...but thats assuming you can drive and have traction....even then, its probably gonna take 10 psi and some very good driving IMO.
Anyway, your best bet is trying to find a used kit for sale on corral...any of them will do really, paxton, procharger, vortech...theyre all doin the same thing and all have their strengths and weaknesses.
You can find vortech setups for less than 2k nowaday used
