hey guys i got my 2003 termi last november with 19000 miles on it and the dealer told me it was all stock minus the magnapack exhaust now I when i launch either from a dig or in third i peg my boost needle on the stock gauge i was wondering why this would happen i thought it was only supposed to get up to 8.5 any ideas?
10 psi on stock cobra

:shrug:Maybe it's not stock? If you are that curious, take off the pulley guard, if there is one, and measure the diameter of the pulley itself.
most dealers have no idea really what is done to them. the on i test drove was completely stock and the guy told me there was exhaust done.
measure the pulley would be the way to find out. plus the stock pulley is huge. i couldnt beleive the difference from stock pulley to say a 2.9.

thanx for the input im going to measure i think its stock it looks pretty big but still has the guard so ill measure that i think im going to go with the colder weather its down around 48
2lb lower?
im getting 10 psi of boost out of a completely stock engine im going to measure the pulley but i think its stock it looks big behind the pulley guard
might have a canned tune
Actual max boost on a stock Cobra does definitely vary. I've heard some report close to 10 psi. Can't remember what mine was. So what you're seeing sounds close to normal to me.
I see you're a newer member. And congrats on your '03 Cobra. You might benefit by browsing through my Terminator FAQ page on my website. Lots of good, basic information relative to the '03-'04 Cobra. http://stangshiftergaskets.com/2003_2004faqs.htm

Mine would peg the stock gauge in cold weather w/K&N and borla catback)
my boost gauge would peg with only a JLT RAI and catback...
My Cobra with 1,729 miles has always seen 10lbs of boost. Maybe thats why it dyno'd 396 rwhp stock.
:rockon: :rockon:
My car w/ 4k miles have hit 10lbs before.
Cat-back/CAI only.

So YOU'RE one of the lucky ones! :lol1: :rockon:
