Not belt slip, boost is logged on the graph and looks good.

Looks like the car yanked a bunch of timing at the end, or the cams moved, or IMRC's shutting. (Look at the boost curve up, as power is coming down)

Just saw that.. He should log throttle angle, imrc, ignition, and cam timing.

Regardless if the intake is/is not collapsing, I'm going to rock a screen over the inlet. However, if boostworks comes out with a nice intake that clears the race bypass, I might end up going with that.

Here's a better option to just a screen:

Not a bad idea. Just need to find one that fits the SC.

Yeah, probably tricky with sizing. Plus, where do you route your imrc vacuum line if you use a SC screen or direct fit filter?

Supra & Skyline guys use these on 88 trim turbos. I'm sure they make a larger opening. ;)

I'd hook all the evap lines to a catch can with a breather on it... Like most turbo guys do on other platforms.

I do not have IMRC anymore. The boss manifold got rid of it all.

Yeah I'll probably do some logging this weekend when the weather improves and see what the dealio is.

I think this line takes intake vacuum to make the intake runner valves operate

I was thinking about this and why I saw boost increases or fluctuation towards the top end of the range. IF an air filter / tube restriction occurred up high like that, it COULD rapidly indicate to the PCM a lower load that would begin closing the IMRC valves, causing a spike in boost (because of increased restriction at the manifold from the closing valves) or a fluctuation as a result. Just thinking out loud.

If the throttle was closing it would lower the boost number.
(since you should be reading it BEHIND the throttle blade)

Hence why I stated you need to look at IMRC's or Cam Timing.
Which when both start moving incorrectly, = more restriction on motor.

More restriction = more boost.

I can move the cams on these cars a small amount, and make HUGE changes in the boost curve. (usually which results in far less power) Ford did a good job on the cam timing. A very good job.

Simple.....

Screen + Hose Clamp = Race Inlet.

But the imrc isn't the throttle body valve right? It's something inside the manifold after the throttle body I thought. The boat/vacuum is measured inside the manifold but behind the throttle body, and I'm assuming the closing of the internal imrc closing would increase manifold pressure. I don't know, I'm no engineer. If the imrc is the throttle body plate, then I'm thinking about this wrong.

Where is your imrc line routed in this set up?

I ran 33 psi, and made well over 550 awhp on a 2.0 engine for 20k miles parted the car out and the piston and heads didn't have a spec of grime on them. Never would I run a "race filter" or pcv junk into a nice engine.

Got the car running with the boss intake manifold but its running with old tune. I am still awaiting revision from lund for imrc delete. The car seems to rev up smoother and idles a little better. Could have been due to my jacked up imrc in old manifold. I am going to drive it around the block in a few to see how normal drivability is.
