Lloyd Elliot is the main man for LT1 head porting, IDK how well any local shops do the job by comparison. http://elliottsportworks.com/

Yea I've looked at his stuff a few times on his site. Heard good things about his stuff.

Yea it was saying on vortechs website a minimum of 12 pounds peak boost is needed. But I plan on one day upgrading the head unit and getting more psi so I think id be alright. Id rather go too big then having to buy another one down the road. Can you still hear it at low boost letting off ?

I'm running the mondo with ~7.5 psi so you should be fine. I have it mounted behind the front bumper cover near the driver side turn signal and you can hear it if you listen for it but its definitely not loud, especially with the V-1 s trim doing its thing.

Ok cool and id say its quiet cause of the amount of boost but yea the noise of the v1 s trim is very loud lol so Id ssay it would be hard to hear. Good to know someone is running it with around the same boost ill be running.

Loyd is def the man. They could "all end up the same", but my heads were done by someone well known before I bought the car, and when I had them re gone through before boost, one of the intake runners was ported too deep and letting oil in. Loyd is the man and you can be sure they are good. Hes also one of the sponsors of ltxshootout, and was there hanging out in Kentucky this year drinking us under the table. Haha. Awesome guy

Making you silky smooth...

Yea I'm gonna look into him on getting my heads done. And lol dang sounds like that was a good time. I didn't make it this year due to starting a new job 2 weeks before the shootout and didn't wanna ask off but I made the 2012 shootout and had fun.

Yea that's what I was afraid of when I bought the p600 I was just planning on about 5 psi because of the n/a non forged bottom end but now that its forged I'm wanting more boost but may not be able to get it. I guess ill try pullying it down and see what I can get out of it for now.

You would be surprised what the "little" p600b can do! Its more about air flow than boost. I'm still running the dual plane intake manifold and was able to get mine into the 9's with the "little" p600b. The highest boost I saw was 12.8psi. But like I said its about air flow not boost. I am switching to a single plane intake this season to have a better flowing intake and going to push the p600 even harder. We shall see...
