Jackson Racing SC
Jackson Racing Oil Cooler
JRTuned Tune
VP Racing Motorsports 109 Fuel
13K Track Miles - 10K NA / 3K FI

I figured this would happen at some point.
Engine had a strange off throttle oscillation that couldn't be tracked down.
Here is what my oil pan looked like after a connecting rod let go:

Some superchargers wear a hole through the bonnet because the pulley on top touches the bonnet.A smaller pulley destroys the supercharger from over revving.

lol nice try, pretty sure it's covered in the manual.
And smaller pulleys can do that to any supercharger out of its spec.

Even on 109 fuel? any logs?

People with issues on JRSC are starting to show up, always good to know that this is not isolated to just one type of FI or manufacturer, but our oem blocks.

Sorry to hear! Can you describe what this oscillation? was it during throttle lift?
