MBT is minimum timing for best torque. Basically you put the car on the dyno, set it to run straight across a single row, and advance the timing until the power stops increasing (or it pings). That's MBT. Then you back it off from there by a bit for safety.

What the actual MBT value will be depends on a whole bunch of things (backpressure, cams, cam timing, boost level, RPM, etc), so you pretty much have to determine it experimentally for each engine config. That's basically what 80-90% of power dyno tuning is all about.

100kpa row should generally be 29-30 ish between 5000-6500. Taper down towards lower RPMs.

Cruise cells at low load can be 40 or more for fuel economy (not so important for a track car).

Everything looks super solid to me. The ziptie between the oil feed line and the crankcase breather is going to last about 45 seconds on track There should be enough length in the oil feed line to route it around the outside of everything and around the forward edge of the heat shield.

Aside from that, there are a ton of nice details here. Well done.

Thanks. That zip tie was temporary while the heat shield was built. I've since re-clocked the oil line so no support is necessary. Do you have a pic of the routing you usually use? Mine is still going backwards towards the firewall

Nice build. I should post pictures of my EFR build too. I am lazy.

How are you feeding air to the oil cooler in that location? I was thinking about placing mine there to have better flow for radiator but I am giving my set up a try first. Oil temps are great on hard canyon runs, no track yet.
