Gang, I traced the vacuum leak tonight, and ran a temporary test to determine if it was indeed the culprit, and it was. The SM4 has its own built in MAP sensor, and it strongly recommends the hose from the sensor on the SM4 be dedicated only to the SM4, and connected to the intake. It was not hooked up that way. The Defi Boost gauge and the Greddy Prefec B were T connected to the same hose....an absolute problem set up like this. The reason I knew I had a vacuum leak was that my pressure readings never changed when I started and ran the car....It stayed at 100 kpa. So, I ran a temporary test hose from the SM4 to the intake, then plugged the hose to the gauge so it would not leak either, and then started the car. Sure enough, the kpa dropped down to 58-60 while the engine was running. So, that was the problem. Idle is still rich at 11.4, but I am in contact with Ian Hamwood from Autronic, and Enzo from New York. Phenomenal support from these guys!! We will get this adjusted more when we tune. Motor sounds much, much better now, and the throttle response is instant.
Transnission shifts in all gears. getting closer....
I have more of the engine put together, so I thought I would post a few pics of the engine bay, as this is a little closer to what it will look like when I have it completed. I also took a few pics of the iForged wheel again. a little better lighting.
