When does the 1G BOV start to leak?

[LightningGSX]

Why don't you just do a test and see? Rig up one of them boost leak testers, but put a vacuum nipple on it too, plug the BOV vacuum line into that nipple(which will simulate normal boost operation).Slowly pressurise it, watch the boost gauge, and see when it cracks open(probably by a noticable drop it PSI)

We found the limits of the stock BOV while on the dyno. The stock uncrushed would leak around 17 psi. The crushed was good for over 22 psi.

yep, gained 12whp just by swapping to a crushed BOV.

But the crushed one would'nt open fast enough compared to the uncrushed, so the pipes would blow off when I let off the gas.

get a 2g one, i hear that one holds like 30psi, didnt you know that plastic is better then metal. LOL

Next post in a tech area like this and I will ban you Tom. Just think about shit before you post for once.

My 1g bov leaked at idle. After I setup my GM MAF and MAFT in blow-through configuration, I vented the 1g blow off valve. It would suck air in at idle sometimes and it got really annoying. I bought it from a friend who purchased it brand new so it wasn't worn out, just doesn't like to be vented.

Mine holds fine past 21psi... Its crushed and a 1G junkyarder...lol
