how much boost will stock internals take?

[cobraivan]

I've got a 99 cobra with a vortech and an air-to-water, I'm pushing 13 psi at redline. I'd like some more boost at lower rpm, 2.95 pulley ? That should put me at about 14-15? How far can you go if you have enough fueling?

depends on how hard u drive it all the time. seems like many people push their stock blocks to like 14psi but take it easy alot. i personally will stick between 6-9 psi

yeah thats what i think too! some guy is using a vortech at 14 psi and i dont know how he does it besides an intercooler setup. not like that will help a ton but i guess its a start in his mind
