Awesome!!!! Nice to see another GN out there doing well!!! Congrats, Is that Max PSI you can run?

[Barnesgn231]

I have an SMC single nozzle kit. The most boost I've ran is 24 with it but only in short bursts. At my power level (335 horse) in the 1/4 I am just about tapped out with the single nozzle kit. Maybe with a bigger jet or dual nozzle it could support more power. To tell you the truth in the future I'll be porting my heads and perhaps going roller at that point I'll dump the alky and run 16 psi. And make more power than at my current 20psi.

What Size turbo are you running?

Yes, porting the heads will make a big difference. But don't back down the boost or you'll not take advantage of the heads. I'm running 25 psi w/ a single Alkycontrol kit, champion ported irons, t63e turbo to the tune of 10.70 @ 128. Lots of boost is where it at with these cars....
