Manifold Vacuum

ED9man Thu May 03, 2018 3:51 am

Hello,

My set-up is a D16Y8 freshly built, basically just a stock rebuild. PM6 pistons for a small compression bump and Bisimoto Stage 1 cam. Initially I was having issues with the default fuel cut setting, when coasting in gear above the default rpm threshold of 1,950 and throttle at 0%, I was consistently seeing manifold vacuum above 213, ranging from just above to the 240 range. Should I be concerned? Is the default value on the low side or should I be looking for a vacuum leak? Trying to get a baseline idea of expected values.

Thanks

213 is pretty standard. The cams may be doing it, or a leak, or the engine build. Simply adjust as necessary.
