preparation, testing, cost cutting, presentation, etc

Priming pulses should be near zero on high-overlap engines.

Lots of IO is a good thing, use a connector with as many pins as you can.

Two or more men should check everything. Just for sanity. Humans make mistake. It's like code review but for metal.

Things I already knew:

Fuel systems shouldn't be return-less without OEM-spec development... (air lock post dry system = long starting time)
Fuel pumps should have a check valve in them (to maintain pressure post shut off)
Front brakes should have greater thermal capacity, pad area, and clamping force than rear
Air temperature sensors should be open element type and mounted appropriately
On AND off overrides on fuel pumps, cooling fans, water pumps and other similar things are highly useful

The first sentence means: Kids will be optimistic and not start things early enough, and leave things too late, ending up with issues as a result.

Priming pulses, zero is an option, but there are other options that would work well for a car of this nature, such as prime on crank.

Publishing the above unedited!

Comments welcome!
