Going to the Runoffs, Upgrading my engine (pictures) Options

[ChrisFoley]

I want to make a good showing at my first SCCA National Runoffs so I decided to upgrade my backup engine. (I don't have a real race engine right now.) I'm installing my 94mm Nickies set

F Production. There are 5 914s entered this year, out of about 38 cars. Three of them are from my division (Northeast).


The alternator is long gone. I don't have much wiring in the car Paul, no relay board either. The car starts with the same column mounted key switch that the car came with. I cut down the stock fuse panel to 3 fuses and mounted it in plain sight on my auxillary gauge panel. The fuel pressure and oil temp gauges are mechanical. The only significant draws on the battery are: starter, fuel pump, ignition and brake lights. I have been using a Pertronix and Bosch blue coil, but I'm switching to a Mallory Unilite with Mallory coil. I've heard that MSD type ignitions don't like running on low voltage. My voltage is typically around 11v, except right after a recharge.
The battery is a regular 914 battery (group 42?), mounted inside a marine container. I have a big grey disconnect on wires from the battery that hooks up to a connector on my charger. I usually run the charger for 15-30 min after each on-track session. I killed the battery at a PCA autocross one time with two drivers. Too many times using the starter.

I have not replaced any panels with fiberglas yet, still have the stock windshield, and will have 60 lbs of ballast on the passenger floor to meet the minimum of 2020 with driver (approx. 230lb). The car has almost perfect left to right balance now.


I've seen pics (PPBBS last year maybe) of a gear driven horizontal fan for a 6 but don't know much about them, and haven't seen one up close. I did look at the 917 fans at the first Rennsport Reunion. I think the drive shaft comes up through the center of the crankcase on them.
