Yup fixed oriface pcv under the intake. I plugged mine when I had the manifold off while I redid the heads. Put two breathers on the valve covers and called it done.....redneck yes but it works....beats blowing boost into the crank case.

Got some testing done today:
Here is how the stock Whipple induction looked before I started......
I had to use the tube that came with the Whipple kit that hooks to the throttle body because there was just no room between the intercooler and the firewall. I installed the air filter directly to that tube as seen below.......
I was pretty hopefull, but unfortunately there was no change at all in blower pressure. It spiked once at 148kPa, but that was the best it did. Most times in boost it varied between 138kPa-144kPa. I saw no signs of belt slip either....so at this point i am unsure where my problem is. This setup eliminated 3 feet of 4" induction tube as well as the old filter, filter box, and air draw that was being pulled through the fender well. This tells me that there must not be any restriction in the Whipple induction kit. The blower did sound cool with the induction removed and i will try to get a couple clips of that uploaded later. I am confused and open for suggestions

It was actually just for testing purposes to see if i was getting a restriction in the old intake tubing. I dont plan on keeping it this way, especially now that i know it didnt make a difference. TB is stock...what is that, 80mm?

Nope, but i would imagine if there was a drop, it would be reletive to the pulleys I have been trying. My pressure has not gone up even when changing to a 1/4" smaller pulley.

He needs 3 test ports in the intake: one on either side of the throttle to show if it is a restriction, and one by the filter to compare it and the one outside of the throttle, to show if that Whippletube along the firewall is as restrictive as I personally think it is.
Then another pressure sensor betwixt the blower and intercooler, to compare with the MAP reading, to see if the I/C is restrictive.
