How much boost can the stock S/c push

[tyler87]

I have a 2003 cobra and i am wandering What is the maximum amount of boost you can squeeze out the stock charger??? I think it has the 2.8 pulley on it now not sure though. Is there a way to tell which pulley it is? So my question is is there another pully that will make more boost or will i have to go the crank pulley route? What is the max safest boost to push with the stock motor

I have heard you can go to 25 lbs of boost but safer to keep it under 20

Probably better to keep it around 16 or so before loosing effiency .

If you have a 2.8 upper already I would get the blower ported. It's inexpensive and will give more hp than adding more boost on a stock blower. Also then if you want more the ported blower will take to more boost via lower pulleys much better. With a 2.8 upper most run a 2 or 4 lb lower pulley putting the boost around 16-17 psi which seems to be ideal with pump gas.

16lbs is a good sweet spot. 18lbs tops ported or nonported. After that you'll be making nothing but heat and shifting a whole lot lower in the rpm range becuase the harder you spin it the hp peak keeps going lower and lower.

Maximum pulley combo from BADASS03SVT and I have found is 2.9/6lb.
