Any updates? Very interested in hearing the results..

Got it on late today. Did a few pulls. Had a few issues. Will be finishing Saturday. Ground issue on bank 2 ignition. 2 rockers backed off. Both resolved. Now fighting sensitivity of knock sensors and dyno

Here you go. This is with belt slip. 150kpa pulls. Both 200 and 300 rom/sec. Minor changes between pulls. Will get some datalog screenshot posted as well. We were picking up still by leaning afr when I called it.Would guess could have hit 780 pretty easily. Will be full 158 kpa when installed in boat.

AFRs look a lil fat. Maybe you're leaner off WOT.

We kept them fat on purpose as a safety net. We did have an exhaust leak on the leaner side but the o2 for holley was on the side without yhe leak

Rich mixtures can help keep exhaust valves cooler. I talk about this on allmondmarine.com/blog in the series on valves. Might be worth a read.

Now that we dynoed the supercharged engines Im going to implement in some oil breather/catch cans. Which ones do you guys recommend for marine application

what supercharger is it again?
