Looks great B.
I was thinking of the heat from the PCU a few weeks back. It certainly looks like you will be ready for some endurance races.
Thats my plan, while most of my cars use will no doubt be sprints and club days, my cars build is aimed at endurance.

Will you be running a system where you can transfer data back to the pits each lap? I know the Mazda guys at B12hr had a system where they could send back telemetry of a lap as they passed the receiver they set up in their garage. It was only capable of transfer of small amounts of data but I believe there must be a way to use current 3G or 4G tech to transfer data in real time. Certainly with all these new apps available you must be able to watch a data stream in real time via a mobile device.
As you know i have all the Motec gear, can download very fast when in the pits or garage ect, but yes, at some stage the plan is to the Motec telemetry, which is the same as used in V8SC ect, so its a radio / modem device, is constant connection, most places.

Are you fitting a steering wheel potentiometer to compliment the brake and accelerator? Could be handy for driver training. It is something I would like to look at once mine is up and running.
Yes i will be fitting a pot for steering angle, will be a rotary pot, the 2 wheel belt driven type, in the cabin off the steering column.

I see you still have the brake bias lever. Are you going to fit non power assist brakes, dual cylinders, adjustable bias as I have done? If not, you will have to fit your pressure sensor after that lever. It is also a well proven way for brake adjustment.
Yes i am running a pedal box, Tilton like yours with 2 AP Racing masters for the brakes (front & rear) with balance bar.
I have there a bias adjuster for the balance bar and the AP racing proportioning valve.
When the car is all running i prob wont require the proportioning device but seeing as everything is new, ie pedal type, ratio, masters, rotors, calipers ect, there will be ALOT to setup and change, alot of info will come from data logged but obvioulsy i need to adjust alot to get it right, so rather have alot to adjust from my seat then go back to pits, hop out, adjust stuff, wait till next session, warm up car, brakes, tires ect same temp to see if the change is right or not.
The balance bar on the pedal when adjusted is pretty much fixed, ie when adjsuted to be say 60/30 it will be a similar ratio hard braking or soft.
The proportioning valve is also fixed ratio, (this one 0.325) what you adjust is at what input pressure that fixed ratio comes in, so light braking its 1.1, bit harder maybe still 1.1 but then very hard the output (rear brakes) is reduced pressure.

What are you doing for radio? Are you fitting a CB unit or just running hand held radio with a power supply.
I have a Kenwood commercial portable (handheld) radio which is on the floor on that carbon tray, has external antenna (middle of my roof) and has adaptor for wiring from my helmet (speaker and mike) and external PTT button (steering wheel)
I have a few of these radios i use for work so have my own private frequency's (few ppl would have seen or used them at some of the track days ive helped out at)
I will be running a repeater with an antenna on a mast at larger tracks
I would recommend portable (handheld) radios over hardwired mobile (truck CB style) units, as if you cut the elec isolator or have batt or wiring fault, it will still work. but yeah external roof mount antenna.

Are you making allowance for cool suit for longer races in hot environments? Very handy for 30 minute plus events like 6 hour regularities, 300km races.
I have a cool suit dry ice box now but is only helmet air, i have nto yet got cool suit or pump for water yet, may do down the track.

Will you have a high beam button on the steering wheel? Another handy addition when passing slower traffic and tormenting people you are battling for track position.
Yes, i have a headlight flash button on the wheel.

Have you 'bitten the bullet' with the fuel surge system we were chatting about?
No havent done any fuel stuff yet, exept whats in the boot, but still aiming for a custom ATL bladder in the original location, unsure if i will use 2x 3" dry breaks for refueling yet, sill thinking i may use 2x -12 Staubli dry breaks under the front bonnet, for clean safe refueling via hand pump on a drum, all depends on how many in-race refueling event i will do, even then most have a minimum re fuel time like 5 mins
