When i get back from iraq the chrysler 300 is no longer going in the garage...it will soon be filled with a 03/04 cobra. I did my time with the whole 2v thing, but just didnt get the results i was craving...not enough HP.

With a stock cobra what is the differance in pullies? ie: The 2.9 pulley puts you at ???hp...the 2.8 pulley at ???hp...and so on.

I have read the reviews on the JLT intake for 03/04 cobras. Seems like its an easy bolt on for the hp. I'd have to see the dyno results to be a believer...but obviously you'll get more gains with forced induction.

One more thing...the clutch. King cobra or the dual plated? Never tore apart a clutch and not sure on the major differances. I saw the hp rating on a king cobra clutch is 450hp...is that engine or wheel power? My goal is to get 400-425rwhp by swapping the pulley, intake, and a dyno tune. Is that possible?

Thanks

has alot of the more common numbers

 

wow thats one hell of a FAQ. I dont think ill ever have to post another question...lol. Thank you very much for the link/help.

one thing i didnt see or may have overlooked...what is the limit of the stock injectors?

 

they will make it somewhere between 550-600...they are about the same as the 42lb injectors.

with the 2.8 pulley that will put you at 450-470 hp and the same upper pulley with 4# lower will get you close if not over 500 wheel horsepower

 

i beleive the fuel pump will need a boost-a-pump to get past around 495rwhp-500rwhp ish.

cause i remember my friend was going to need one, but he ended up selling it. and maybe an MAF extender? i cant remember what the stock MAF goes til.

 

The 03-04 Cobra have their own special made 11" clutch setups. So the old 10.5" king cobra is not what you will have or need on that car. Most go with twin disc setups because they are much smoother. And like they said with a smaller pulley, a few supporting mods most get 440-475rwhp with them.
