Stock 3.65" pulley is fated @ 8~8.5 pounds. So wouldn't that put you at 12lbs? When you say you added a 4lb pulley... was this a lower or are we talking a 2.93 upper?
You really need to get a full CAI versus the drop-in K&N. You'll pick up almost another 20+HP/TQ.
With your mods I suspect you're somewhere around 440 RWHP. Are you using the canned pulley tune from the Predator? Reason I ask is there's more HP to be had if you get a tuner to supply you with a custom Predator tune...

LOL Yeah I figured U were messing with me.. a 4lb pulley would probably be too big to fit under the hood.. hehe
Anyways, yeah I think your right.. Stock boost is actually 8 - 8.5. So your right, actually I'm somewhere in the 12lb range. The gauge reads 10 lbs, and it would peg it with the stock pulley, but the guage is probably not exact. And its an Upper 2.93.. not a lower.
About the CAI, you think itd really make that much differance? All my friends here say its pretty much just for looks. Barley any gain over stock set up...?
About the preditor.. I have the stock tune set up for that pulley size. I need to get someone get ahold of it that knows what their doing and tune it. I had a 2003 GT before this, and ran a 9.40 in the 8th, and let my buddie re-do the program, and he got an 8.80 out of it just from messing with the preditor!

Actually the guage is pretty accurate all the way up to 15lbs. They make an overlay you can install along with a small mod that will allow the stock boost gauge to read all the way up to 15.Padg said:
The reason you may have been seeing 10lbs with the stock pulley could have been due to the drop-in K&N plus the cooler weather. Keep in mind that most mods you perform to open up the intake side of the engine will show an increase in boost and exhaust mods will drop the boost.
Do all your friends own & drive a SC'ed 03 Cobra? Trust us in this forum, we've "been there & done that"! The stock airbox is pretty damn restrictive and although a drop-in K&N will add significant gains over the stock paper filter a JLT, Steeda, or K&N FIPK is worth 25 RWHP over the stock airbox & filter.Padg said:
There's not much you can do with the Predator on your own that will increase HP/TQ over the built in tunes. You can adjust the air/fuel ratio but unless you're on a dyno with wideband I suggest you don't monkey with it! Get someone who has the ability to build custom Preditor tunes to email you a new tuned based off of your mods.Padg said:About the preditor.. I have the stock tune set up for that pulley size.
