I have v9-g-trim vortec kit 6pd need advise on moving up
 

i have a 2000 ss with 6 pound kit from vortec no after cooler engine is stock. car has entire stock kit from vortec installed. I want to put more boost on car what can I do and what do i need and how big can i go.
my mods are full length headers, off road y-pipe, flomasters cat back,slp cool lower ram air and the entire 6 pound kit(whatever came with it)
also can i put the bigger mass air on or throttle body ect. let me know what can be used as well
I thank everyone for any corect advise

Well the first thing you could do is order the aftercooler kit form Vortech and then you could run there 8-9 lb set up larger crank pulley ETC... and then if you want you could even go with a smaller pulley but becareful not to get to carried away though.

thanks

Yep get the aftercooler next. Also ditch the flowmaster they don't flow worth a crap.

2000 SS:

6 pound kit from vortech
full length headers
off road y-pipe
flomasters cat back
slp cool lower ram air

If it were me:
-Get that custom Vortech airbox that Brian Brannen is making ($150)
-Change your muffler, I would get one that is straight-thru with perforated baffles on each side, can you afford stainless? ($70 or 150). I would get something like the ATR Pitbull, Borla XR1, Dynatech Splitflow, Dynomax Ultraflow welded (not bullet)
-Keep stock MAF
-Might suggest get a stock ported TB
-Aftercooler from Vortech
-Colder t-stat

Brian has stated that he will be charging more now that he did this last batch with out making a penny ETC... We paid $165 shipped I don't know what he is planning on charging though. Just a heads up on that.

Depends on your knowledge level, but to up the boost you either need an intercooler or a good alky system or run around on 112+ race gas. Otherwise you WILL break some pistons or do damage.
A good flowing exhaust is a must. Forget about MAF'S and TB'S until you up the boost. Right now they won't do much.
A 2.85" pulley and 49.5" belt combo along with a good alky system is the cheapest way to go.The alky system will cool down the charge pretty good with a 2.85" and also give you the extra fuel you will need. I Ran that combo for a long time.
It'll give you 9-10 psi depending on weather with stock heads/cam and REALLY wakes up the motor. Going from a 3.7" pulley like what you have now, to a 2.85" will make you think you never even had a blower on it before.:burn:

All the kits use the same 8" crank pulley.
My system began life as the non intercooled kit 3 years ago.

Aftercooler, headers, heads & cam.

Aftercooler kit ASSEMBLY from vortech (i have the part no's if you need them)and pulley down that's an easy 50-70 hp there. get rid of those crapmasters i mean flowmaster and get a better flowing muffler like a magnaflow.
where is your graph, what kind of timing and air fuel are you running. it is not suggested to go above 9 lbs on the stock bottom end, you're pushing it there.

if you haven't already get a good flowing air filter like a holley.

get a tune change the plugs to ngk 6's that could work marvels on your car.

a mild cam (you don't need big) will give you 20-40hp. mid 500's on lift, 220/224 split with 114/115 lsa.

believe it or not the 02-03 ls6 cam makes a good blower cam. i recommend getting the best valve springs money can afford and upgrade to hardened pushrods.

that should be plenty of powa to hold you over for now.

thnks but what MM TB to buy there is 2 types

Does anyone know where I can get the ls6 cam and all the springs and pushrods in a package?

try parts@sdpc.com for a quote on the 02 or newer LS6 cam.

I got my ported TB from Bauer but Jantzer is good too.
