Maximum boost is now 8.4 PSI. It is hard to really see the latest intake tract in the pictures.
Basically it is a 2.5 to 3 “ coupler off the throttle body, to a 90 degree elbow, to a 60 degree elbow to the filter.
As you can see the old and even the RX-7 intakes were inhaling warm air from the exhaust manifold.
There was a heat shield on the original that is not in the pictures, but I bet the new setup gets cooler air.
Intake temps during the dyno runs were around 90 degrees with the hood open and a really big fan blowing on the engine compartment.
The 8.4 PSI was measured using the eManage Ultimate and GReddy Pressure sensor. The ambient air temperature during the test run must have been 50 degrees, because that’s what the intake temp read.
One other side effect, boy can you hear the blower whine now!!!
