Update:

Finished Pre-Chamber v3.

This newer version has a much better flame torch then the last two versions. This will help with flame speed during my ultra-lean burn.

Also seeing lower spark plug temps and head coolant temps. This was a major win for me for the way I design my pre-chamber, it needs to run much cooler than other pre-chambers for fuel collection.

Also did some GEM31 fuel testing with the v3 and it runs great. This fuel comes out to around $4.40 a gallon. So, the next test is to see what the fuel mileage is compared to E10 gasoline. My math and homemade gas generator say it will be around 31 mpg Freeway.
