cobra newbie. need another mod!

leo540i · 03-02-2009, 06:03 PM

Right now I have:
-2.8 pulley
-bbk dual blade throttle body
-magnaflow high flow cats
-slp loud mouth cat back
-spec stage 3 clutch
-heat exchangers

On a conservative tune it puts down 440 whp and 460 wtq and I use the handheld predator to tune it.

What should be my next bang for the buck modification and roughly how much power can I gain from it? (without having to buy supporting mods) So far I'm looking at:
-lower pulley (don't know what size, brand, and belt size I would need if any)
-ported plenum (does it help?)
-upgraded MAF

port your blower

Save,save and save again for a TS.

leo540i · 03-02-2009, 06:11 PM

What is a TS?

I like how the car pulls right now and am just looking to safely squeeze another 15 hp out of it (if possible). In the future I would maybe port the blower, but not yet.

Can I tune with my diablosport predator for a lower pulley?

Twin Screw,KB or Whipple.

I probably will not keep the car long enough to go that route.

Anybody?

Then keep it the way it is, You will never get your money back for the mods you do.

That is ok. I am simply looking for a quick fix for now.

Anybody?

IRS brace, no power, but saves a $2,500 rear end rebuild.

Port the blower, or buy a used, ported blower.

i went with a used one they are on the market for cheap i bought my black stage 4 ported eaton for 600

I'm assuming you have an intake, if not that should be first on the list. Either a lower pulley or port the blower. You're looking at $329 for a lower pulley along with $40 for the alt pulley and another $45 for a new belt. Or a ported blower from Posi will run you $430, or find a used Steig for $600-$700 and sell your stock blower to make the money back.

You said you were tuning it yourself on the Predator? A good custom tune by an experienced tuner will probably get you another 10-20 HP by changing other parameters in your tune, and improve general driveability also. There are quite a few reputable tuners mentioned in these forums that you might want to call and ask...
I use Rick at Amazon Tuning, and I've also heard lots of good things about Justin at VMP, Ed at RWTD, and the list goes on...

CAI would be a quick, cheap, upgrade. However, you might want to do some suspension mods like an IRS brace and subframe connectors

leo540i · 03-03-2009, 10:15 AM

I forgot to mention in my list of modifications. I do have the IRS brace, the car is lowered, has maximum motorsports adjusters/shock towers (?), and a cai
