which end do you blow into? There are 3 holes....
I can't blow through the J-boot or "vacuum line" side (the top and bottom)
BUT if I blow into the intake side it goes straight through the top ("vacuum line" side)

Sorry guys.

Acetylene - I have been trying to get back to the dyno for the past 3 weeks. The shop that I used last time, paddock performance, has been pushing me aside every time i have called. I will try yet again this week and post up if I am successful. Unfortuantly I am stuck going to them as they are giving me the next 3 pulls for free. Wether or not that ever happens remains to be seen.

Kyle - Good question. Im pretty sure it should not matter, it should only be an open passage between the boosted side and the intake side when there is vacume... but do a search, as I am taking a stab in the dark

Steve - the vaccume leaks were at the throttle body o-ring, and the banjo bolt off the intake manifold

Keith - Take the valve out, it takes 5 minutes top. I dont think sucking on the vacume port is giong to tell you anything

I asked thids before a long time ago, but never really got any good data.

Has anyone tried experimenting with different spring rates in the DV?? To increase spool up after shifts, etc.

Yep, k26/6 235rwhp, 308 rwtq, 17 pounds of boost

Im pretty happy with that. How does that compare to what other people are seeing with this setup? Basically its the lindsey instant rwhp kit with a 3 inch exhaust and testpipe

How can I go from the Turkey Gobble to the Cobra hiss or the pshhhh sound that the blow off valve offers?. I thought the 951 diddnt work well with a blow off valve due to the inlets, is there one out there that is made better than the oem bosch part? there is a guy on fleabay selling them for about 70.00 in aircraft grade aluminum or 4130 chromo.
