2020 Report (continued)

I want to add two comments.

The first new comment to 34-40 is regarding the Stage 1 water pump v-belt. The upper alternator mount only allows about a 15-20 degree contact with the water pump pulley and the water pump was the main reason for this overall change so we stretched a smaller v-belt over the second pulley set on the crank and the water pump. It does squeal if you just go right to the starter but for some wonderful reason if I allow about 3 seconds to let the electric fans start with just the "On" part of the starter key and then turn the switch fully to the right to turn on the starter it starts without a squeal!

The second new comment is that I was surprised that (118 psi/14.7 psi/atm) = 8.03 CR because I originally had the 882 heads cc-ed for a 9:1 CR. I do not have any previous experience with spark plug pressure readings, are they usually low?

Best Wishes,
