depends how much boost do you have? Typical numbers for a stock 99 cobra motor with a entry level centri would be around 420-470 rwhp range. There are a select few out there pushing a lil over 500 rwhp with spot on tunning. Since your new to the game and live in so cal.... take your car to RET and they should guide you in the right direction.
Well the pulley is the stock 3' inch I believe only making around 10 pounds. Full babsani exhaust no cats I believe. Pretty much all stock.
@wma- I know about RET all friends build their cars there. I'm gonna take it in a few weeks. Are in the street racing scene in Compton?
3'' on a procharger?? That doesn't seem right that would be a ton of boost. Maybe be a 4''?? either way 10psi depending on timing should land you around 450-470rwhp depending on if you have the fuel and maf to do so.
A buddy of mine has a vortech 99 cobra, he put down somewhere around 460@ 6000rpm, with the miles on the motor the dyno tune shop didnt want to push it to 7000rpm, Im sure it would of reached 500hp.
