I made 18.3 lbs with the 2.8 pulley and a stock lower. I've seen 20lbs on cold days before. I'm also running ARH long tubes with a 3 inch o/r X. 21 to 22 lbs sounds really high. I'm pretty sure the 2.8 pulley is a 19lbs pulley.
Are you running a catted mid pipe? Last year I brought my car to the dyno and saw 2 extra lbs of boost. I hit 21lbs with the 2.8. Turns out my cats came apart and blocked about 60 percent of my exhaust. I still made 598/570 lol. I gutted the cats and the boost came back down. If your running cats I would check them asap. The exhaust wasn't much quieter being blocked and the cats were only 3 years old. Converters are bad news.Yea idk man. But I don't want to push the car past 18 lbs.
yea 17-18 lbs seems about right with longtubes from what I've seen. I've been on 2 separate dynos now and both times saw 21+
My tuner said I would see 20-22psi on the 2.9" I orders with it. VMPs chart is definitely off from what I seen.
15psi on the 3.3" is what I ended up with.
Can you send me price for gt500 kit and fuel kit? See if I can make this work...
Did you guys mean to reply to this thread or another vendor on here? http://www.svtperformance.com/forum...ree-Shipping-amp-0-Financing-for-up-to-1-year! I don't recall anyone selling the unit from the official thread.I would like a price on the kit also, with the gt500 intake.
