With a CAI and a x-pipe and a catback my car came out to 387.2 hp and 389.1 torque.

But with these cars the power is so diverse B/C they are hand built so results may very...

If you get it dynoed let us know...You may have a Factory FREAK!!!!!!

I totally agree. I tossed an F1-A ProCharger on mine. With a Plasma boost, KPN CAI, Accufab intake, and a decent MAF, i turned 589.00RWHP, without the suspension mods, Several here have gained better. I have a bunch of things done to mine in addition...Meth injection, etc.. I"m talking just horsepower mods.

These 2003 - 3004 4V Mods beg for anything they can get. FMC outdid themselves with these 4V motors...badassed horsepower is on tap, just have to harness it.

Oh yeah, i did this without lifting a freaking valvecover. There are several here who can verify this. Can't wait to spray it once i've planted the RWHP.

With a quality CAI, Xpipe and cat back you should be in the 415-430 range. (Dynojet or eqilivalant)
I pulled 428 with my JLT CAI, Bassani catted X and cat back.

I have a 2004 Cobra with a Flowmaster American Thunder Series Cat Back, K7N FIPK Cold Air Induction kit, and a SuperChips tuner and dynoed at 396RWHP. I'm seriuosly thinking about getting the stock Eaton ported w/ smaller pulley kit. I'd like to be around 450RWHP.

I got my Magnaflow Cat back installed and it really made a difference
in seat of the pants power. The exhaust has a nice mellow tone at cruising
speed (some droning in 6th gear 55-65 MPH .... but not bad) and absolutely ROARS when you wind it up past 4000 RPM. It will definetly put a smile on your face the 1st time you jump on it. (do this test w/o spouse .. it gets loud).

So, I'd say with my CAI and Cat Backs the car has gotten much stronger. Anyone know what installing H pipes will do for sound ? Louder or quieter ? I agree that you want to be quiet at idle and cruising.
Having a sleeper is cool ....

do you get a scratchy back noise from the super charger. i`ve never had anything w/ a supercharger. so im not sure if what im hearing is "normal" when accelerating. ive been told by a mechanic that, that is just the noise you get w/ a superchrager. however, that is also the same mechanic that is going on replacing my 3rd throw out bearing. so go figure.

Open 10'' K&N filter and borla stinger catback

400.2 rwhp
370.1 rwtq

These numbers are SAE. I've since added the MAC prochamber and MAC CAI and picked up 3.4 mph in the 1/8 mile, so power was definately gained.

From what ive seen, it's either you have a freak HP or freak TQ...obviously you have to lose some of the other to gain...take myself for example...450rwhp/495lbft...everyone seems to be within 10hp of each other with the simple bolt-on's...good luck with the tuning
