7 on a stock motor, 8 with a good tune. I wouldn't encourage doing more than that unless you are running a little bit of meth, or higher octane fuel.
Invest in a good boost gauge.

Robert K, thanks for the charts/graphs...that is just what I was looking for...the 530's & the 700's. By the way where did you get this info?
OK, I saw the link, disregard the question. Thanks again.

or what is the maximum WHP if you have internal mods - piston, rods, cams, fuel system, tuning etc..?
in what psi? 14 psi? or more?

We maxed one out at pump gas about 13-15psi range...curve looked pretty good. After that, we got a lot more trq, but crappy power curve.
As RCDash mention, this turbo is pretty tapped out beyond 15psi.....figure about 440-500whp dependending on the dyno used.

If the jwt 530bb kits Has 440WHP - 500WHP -
What do you think its drag time 1/4mile (400Meter) ? 12sec? 11.8sec?

With a Auto G35 Coupe and the JWT 530bb kit I pulled 350hp/350tq on a dynopack. Thats the twin turbo kit with just test pipes. I am pushing around 7.5psi. I only got a chance to run the 1/4 mile 3 times and my quickest time was 13.3 at 104mph. I am still using stock exhaust and stock motor. I am sure I could get mid 12s'ish. With a 350z 6 spd I would assume you would be able to break into the 11s. Atleast a really high 11 or really low 12, which I think is still pretty dam fast for such a entry level kit with no motor build. Hope my experiences help. Good luck with your build.

At 2230' DA I run 12.7 @ 112mph 2.09 60' with street tires and 6.8psi aprox 380whp or SAE corrected 397whp. At sea level(or elevations under 1000') with some drag radials and 440-500whp, low 11s should be possible.
