Listen for knock, and get out of it if you hear any. My clutch lasted only 6k miles with boost (3k at 5-6 psi, next 3k progressing to 10 psi), so go ahead and leave some room in your budget for a clutch.

Al, my car would bust em loose at the very top of 3rd. If you compare my dyno graph with say BRG's, I think you'll see how the greddy kit with some management and a downpipe rolls power on nice and linearly, while a more "stock" kit acts like a lightswitch.

yeah at 7 psi with BFG Gforce KDWs mine breaks loose in second, haven't messed with third much. Damn thing has bene taking too long to get the bugs worked out to mess with it all much.
Soon though, very soon. Learning to Tig aluminum this week, that is key in me having the car back on the road.

BOV shouldn't sound like a turkey gobble, that's what compressor surge sounds like. Make sure your BOV is actually working.

if you overtighten your BOV it can sound like a turkey, or squirrel... its totally fine if it is that way

Al, im runnin at 5psi right now as well with 8* and the thing goes like a bat out of hell (compared to stock). Ive got azenis and it frequently spins in first gear a little bit with pure accelleration and second can spin with a hard shift. This is with an open 1.6 diff though, so its apples to oranges compared to a lower ratio 1.8 torsen rear end. Ive got a 1.8 torsen ready to swap, im sick of spinning my tires on corners

Not exactly. Turkey Gobble describes compressor surge. As the compressor blade spins violently out of control and the opposite direction.

Overtightened BOVs would be described as "fluttering". Imagine swinging a flag through the air really fast.

The word overtighten should descirbe the results as not being "totally fine". What is happening is the the bov is opening and closing very rapidly as the spring overpowers the pressure change. The result can still allow pressure to make it back to the compressor. If anything just adjust the BOV to make a proper dump of pressure.

+1 on overtightening the bypass valve to the point of "gobble" as not being totally fine

My tial won't blow off if I "T" it in to multiple vac lines. I removed my upper intake mani, drilled and tapped it for 1/8" NPT and devoted the Tial it's own vac line. Now it blows off easy at low (3) boost psi. Might want to try just giving it it's own vac line to see if that helps.

A GReddy Type-S? Remove the soft spring inside and leave the heavy one. That's what I did.

i like my turkey calling 16g i doubt it effects your turbo anytime soon eventualy you migth get some excess wear on the bearings and maybe untorque the shaft to some extent but that would be a long time down the raod, in my opinion BOV is just extra. Glad you got the results you where looking for with patience and abit more work you will see this is only the begining.

I dunno braineack ive been rocking the stock rubber to limit the strain on my drivetrain through the motor breack in and i get it loos in 4th at 4 psi depending on what i am doing i love going into corners and power sliding it around at the apex F&F redneck drift people.

Hmm i havent driven it much at all, just a few nice runs. My tires breaking lose is deff. because its cold as hell, and they are stock rubber on there, not original, but stock. And it deffinately sounds like a blow off valve, i cant tell for sure, but is there any way to tell if it is working? I have the bov setting all the way on "hard", ill play with that today.

Also is there anyway to make sure my vortec is hooked up right and working? Ill be putting up some pictures later, im at school right now.

Thanks for all the insight.
