Dyno numbers??? Car will hopefully be on the dyno today, but most likely early next week.
So guess the rwhp lol...and this will be on a dyno dynamics, the lowest reading one that im aware of.
2003 lq9
comp pushrods, ls2 timing chain, ls6 yellow springs
ebay ls6 regrind cam 204/218 .550/.550 112lsa
all esle stock on motor...no porting to heads, and even still the stock truck intake
s475 turbo with 1.10 ar
ebay a/w intercooler
stock manifolds flipped forward
2.5in pipe from mani's to turbo
3.5in pipe from turbo-intercooler-tb
93 octane, and i know this will throw it off a lil bit but i dont know how much boost yet, just depends on what the wg springs give us, but anywhere between 6-8 most likely
4l80
3000 lockup stall (will be unlocked for dyno)
3.73 gear
10 bolt rear

Yikes 
I would have definitely done something else. With a regrind, especially going from a 117.5 LSA to a 112 LSA, God only knows the true specs of the cam.
Numbers wise, 500ish...... Keeps up posted on the result. I am interested in what she does.

You have definitely spent a ton of money on the fuel delivery layout and the total install looks good. My only concern would be the regrind as well. LSA should be 117. With a regrind, they reduce the base circle. This requires longer pushrods. This is especially critical if you are still running the stock rocker arm setup. Regrinds very in quality. A simple regrind destroys any surface hardening the original shaft had. Not putting the regrind though a new surface prep will cause premature lobe wear.

I do wish that i had a wider lsa but when i did the small mods to this motor it was going to be na and then 100-150 shot. I know quite a few people that have used these regrinds from the same persone and none have had any problems.
As far as the exhaust i dont mind it being a lil loud, and my last setup was louder than this so im good. I work 3rd shift so i leave home about 8:45 and get home at 6:00 am. And this car is driven every day to work, 1hr round trip.
As far as the fuel system (besides fuel rails) we went ahead and built it to take 800rwhp as my goal for next year will be 700rwhp.
This winter its getting forged pistons and rods to turn up the boost (only around 7-8#s till then), and at the same time itll be getting a custom cam from PatG as well so the lsa will be much better suited for turbo and the higher boost.

were going to Beech Bend today for testing and see what she does. My only two draw backs are that i have 3.73 gears (not ideal, will change down to 3.23 in a few months), and i can only foot brake to 1600rmp for i start pushin the tires, so there will be no boost at all on the line, wishin i could take off at about 2500
nice setup. What size injectors?
This is the car that Chris Coffey worked on? Looks good! You should post other pic of the body. It looked awesome. I like those Buick GS cars!

neither lol, i have drum brakes on the rear end, i can only foot brake 1500 rpm before i start pushing the car (front tires hold and slide, rears just push the car), im hopefully getting some 4 piston rear race brakes in a month or so, so that i can hold the car, stall up some more rpm, and build some boost on the line.
if i can just get the car to 60' like the previous procharger setup (current turbo setup has more power and torque, by 15hp and 20 tq) it should be good for some 6.6 8th mile and 10.5 1/4 mile
