Vortech kit - BOV question

I dont know why I never noticed this before, but the Blowoff Valve that came with the Vortech kit has a small vac line fitting on the bottom of it. I have nothing connected to this and never have. You guys with Vortech Kits, do you have a vac line connected here? if so where do you plug the other end of the line? I

Yes, you need to hook that up. I hooked mine to a tee in the vacuum system.

Wow that was fast! Thanks for the reply. So what problems would/could this have caused by not being connected for so long? I assume if Vac pressure gets high enough it opens the BOV and returns air back to the blower inlet?

The bypass stays open when in vacuum to alleviate compressor surge. when you go into boost the bypass closes. You need that line or you can mess up the blower. Check and see if a line blew off, I have a hard time believing kenny brown would leave that off.

Well I got the car with 55k miles on it and I know the Ford Dealer did all the service on this car (including cracked intake replacement). So I imagine Ford may have done this. Could this being off have an impact on performance or HP levels? With the other mods, this car should be making more power IMO. Last month with Dyno tuning, it only made about 205/250 on a Mustang Dyno loaded to 3900 pounds.

Can you tell me where you T'd in the vac line on yours? There's a small vac line coming from the back of the intake to the passenger side fender (that's pretty close), can I just T-into that one.

Yea no kidding Now the Mustang Dyno generally reads lower than a Dynojet because it compensates for vehicle weight, but I still expected more. Here's the mod list:

Vortech 3.25" pulley
255 lph fuel pump
42# injectors
PI Intake
70mm Throttle body
90mm LMaf
2.5" Dual exhaust (no cats)
J-mod
3.73 gears

I've considered putting it on a Dynojet to see how different the numbers are from the Mustang Dyno. I think I'll fix the BOV first though. I'm wondering, with that BOV not connected, maybe I'm losing boost pressure back through the intake or something silly like that. I've found a local 2002 Explorer engine for $700 so I may pick that up as my next mod.
