more tq with vortech??
#18
try addin' an MREV2 to the mix
or
Kinetix SSV(intake runners, good for FI)
or
Cosworth plenum($$$)
or
Strup or Stillen(2 torquiest i've seen) headers w/stock cats*
or
stock headers w/HFCs*
(*)some people runnin' SCs have problems holdin' PSI when they're exhaust set up has "too much" added flow

i still have stock headers and cats. i want to get headers and cats but am scared i'll make enough power to blow it up once i put those mods on.

The power curve is as is you can change how the curve looks using a combo of intake runner length and headers..
But because of physics.. your S/C wont make any more power then what you have now unless you spin it faster with a smaller pully.. What you have control of is your curve.. but the general result is loss of hp to increase tq.. (only way that this is false is if you're current combination of intake manifold / header isnt at max effiency or is a bad combo)..
Kentix.. thats junk dont even try it.. you can mess around with your plenum.. by swaping spacers around but bigger plenum = more volume = more loss in low end (tq) more potential for high end....
PM me your list of MODs and dyno graph and i'll give you my .02

smaller plenum volume is better for high rpm power while larger plenums are better for midrange power. At some point the air velocity becomes more important than the amount of it that can be stuffed into the manifold at a given moment
btw, the SSV has shown gains on just about everyone who has switched headers, cams, or has headwork.
Pretty much every turbo setup that uses the stock cams with either stock or short /small exhaust manifolds (greddy, APS, PE, JWT, most TN setups, etc) has lost power with the SSV

hope it makes sense my heads a little x.x from the day and i probably jumboed up some words

OP just get rid of your damn bling dubs and your car will feel a hell of a lot faster lol
Also, you are running the stock pulley for the rev up kits so you haven't begun to fully tap the power on that thing. I don't want to insult you but you sound like you are running the standard kit with really no other engine work, more boost or anything else. you are going from mild with a simple vortech kit, to extremely wild with a built motor in my opinion. I say find a middle ground for now
