just bought an 03svt cobra and i want to change the pully, how many psi is it useing stock? the gauge only goes to 10psi... should i go to about 20 or would that be overdueing it? any thoughts? thanks

 

03 uses 8psi stock. boosting to 20psi would be WAY too much unless the rest of your car was modded off the wazoo

 

well on my gauge cluster, it has a gauge, and it sais 0 - 10psi, and when i open it up it tacks all the way to 10... but i just want a smaller pully on there so i can boost it, any thoughts on how much psi i should go to? and how long does it take to change out a pully? any ideas? thanks guys

 

you cant get 20 psi out of your stock blower...the engine could handle 20psi from an aftermarket blower tho, say like procharger or kenne bell

 

New to blown motors. What will be the effects, if any, if you incrcease the boost to say about 12psi on an 04 Cobra? What would need to be done except tuning?

 

no effects, other than hp increase. i recomend getting the most psi you can out of the stock eaton blower tho, you can get more than 12psi. as far as tuning goes, wait until all bpu mods are done.

 

ok cool. thanks for the message too. i responded.

 

I would be VERY careful before you start throwing that much boost into your ride. I've been a broken record tonight, but HOMEWORK, HOMEWORK, HOMEWORK. What is the compression ratio on that car BTW?
