While the subframe mounts are slowly getting done (when I have the odd hour or so in the workshop - two done, one to go), some new parts have arrived.
I've taken advantage of the currently fantastic exchange rate and ordered (from the USA) a pair of Stewart Warner 52mm mechanical gauges to monitor boost and oil pressure. This model boost gauge max is 15psi which is suits this build perfectly since I'll be using the standard CT9 turbo which has a useable boost up to ~13psi. These gauges are wonderfully simple design with easy to read faces and no bling. Gauges are there to read, not to stare at how pretty the lighting colours and fasica patterns are!
I also purchased a PLX Devices wideband O2 sensor module (and the Bosch LSU 4.2 wideband sensor included in the kit). This is a great compact little unit which can be used to drive an analog gauge, however it also provides a linear 0-5V output from air-fuel ratios representing 10:1 (0 Volts) through to 20:1 (5 Volts). I don't yet know how I'm going to display the values from the PLX unit but it may involve re-working the design of a custom multi-channel temperature display I made some time ago to incorporate readings of ambient, intake, oil, exhaust gas/turbo, coolant temperature; and Air/Fuel ratio & battery voltage. All values could be output to a single 20x4 character LCD display with the usual peak values and alarms integrated into the program. There's no need for heaps of gauges mounted around the cabin when you have a single LCD capable of monitoring mutiple parameters.
