Very nice eddy!
I made the hole smaller as to disturb the airflow in the plenum less. The AOS is what controls the airflow through that it, and the size of the hole is large enough to vent the crankcase
To fit the airbox you will have to remove the left side manifold so yes, you're going to remove it
JB:
-Q1: Yes the main goal is to decrease the charge loss, resulting in greater airflow and thus greater power. I haven't really noticed a change in response though.
-Q2: Yes
Few pages back I talk about it.
I did a few test runs, and I've measured an average of 8% more airflow. Unfortunately, I could only compare maximum value, so I don't know exactly at what RPM it happened (probably near maximum power rpm).
I can't do a Y shape, it's patented, and I don't do that to get troubles
Q3: The stock ECU is able to make it run, no worries on that. But a remap would get the most out of it.
Q4: The stock TB for 2.7 and 3.2 engine is 68mm. The 911/987 TB is 74mm, and the GT3 is 83mm.
For now, I only make it for the 911 TB, because I believe it is the more suited for the application, and also cheaper and easier to find.
I will make one the BIG 83mm TB later, and also one for the 996 cars to fit the GT3 TB.
Q5: I talk about it a few pages back too. The plenum and TB should NOT be your only mod/first mod!
That is why I've ask the tester to have at least an exhaust.
My configuration right now is soft, I run eBay headers and midpipes, and the plenum...
I'm going to fit a k&n filter soon.
a 987 airbox will be a good addition, that's why eddy and mavis.d are doing it
I can't guarantee that the car will pass emissions unfortunately!
I'll try to do a summary of everything on the first post
I might have found an easier solution for the AOS to plenum connection, might even be cheaper than the current one!
Thanks guys for everything! Continue to give your opinions!
Ben.
