I have a 2004 cobra coupe and have only changed the exhaust & air filter. What other mods can i make to increase Horsepower? Can the stock supercharger be increased from 8lbs boost to 12? Please advise.

 

Pulley, tuner, drag radials. Oh and get rid of the stock shifter.

 

Keep in mind that if you screw with the boost, you will void any warranty you may have left.

There are tons of websites that sell aftermarket pulleys to alter your boost, and as long as you only go form 8 to 12 you will probably not HAVE to change injectors (although you may not enjoy the full benefit of the additional boost without other mods). Those engines can take a lot of abuse, but don't screw too much with them if you don't get a dyno tune or you may risk running lean.

 

CHECK THE SUMMIT CATALOG THEY HAVE THIS BAD A$$ KIT FOR THE O3 O4S PUT IT IN THE HIGH 500 HP RANGE COMES WITH PULLY UPGRADE DIABLO TUNER AND SLP EXAUST AND A COUPLE OTHER THINGS PRICE IS AROUND $1800

 

Wrong.

That kit is for flywheel horse, and honestly, who gives a **** about flywheel horse.
