Well we finally got around to doing some street tuning to prepare for the dyno and also to get ready for Stillen.Everything works well and the car runs strong.Idles perfect and no CELs.Cant really hear the Synchronic BOVs though but I am not hearing any surging either.I am putting some video togther so you guys can check it out under boost.I added about 20% more fuel under boost to keep it from leaning out so we will see what it does on the dyno.Oh and we will be at Stillen too if anyone wants to check it out

Maybe there isn't enough flow rate (during blow off) to get good sound from both BOV's... Plus all that additional piping volume might be a factor.
I told you to go with one BOV mounted on the shared side of the intercooler.
This looks like an awesome system. I'm really looking forward to see some numbers from this. I'm betting it will really bring great numbers... Let me know when you start selling the kit.

These is less piping then before.

(where on the piping do you have the BOVs mounted? that might also effect the sound.
It is on the cold side(shared) of the intercooler so both blow-off will releive all air inside the intercooler.
If its in front of the intercooler (during the normal flow direction), that will slow the gasses coming back from the piping and the plenums.)

Will do.We have to do some dyno testing and see where we end up compared to our baseline.The car feels strong but seat of the pants impressions suck for comparisons sake

doc, as great as it was, that vid was painful to watch... why so much compression? send me the full uncompressed vid and i'll host it for you... yikes, the skipping nearly gave me a seizure...
btw, could you PM me a price on the plenum?

Will send a pm.The compression was to alllow the average Joe to watch it since it was orignally 58mb.LOL 58 megs for a 2 minute video.
