How many teeth do they jump? How does one determine this? There is no reason they couldn’t jump just one tooth if blipping the throttle aggressively or engine braking.

How many Miata engines have you built?

Here is the first one I did for the endurance car I race in… it has had many podium wins since and we are racing it again this coming weekend in an 8 hour race.
