Thanks Daz
Yeah building a race car can snowball alot more then a daily car thats for sure. If going track only i would recommend starting with safety, so full weld in CAMS / FIA spec roll cage, wrap around seat, harness ect.
Steve,
I would not typically be using any of the buttons on the keypad while racing, more before so just setting up the car before i start, things like helmet fan, cockpit fan ect, all the buttons to control things while im racing are on the steering wheel, well only thing thats on the keypad that i might need to use is say wipers, but if i think it may spit or rain a little, i can program one of the buttons on the steering wheel i wont need in a race, such as launch control, to be for the wipers, just wipes while i hold the button, or toggles it on and off ect, every button, besides the radio button, just goes into digital inputs, not wired for anything in particular, so i can temporary set them to do anything.
And yes i do have a radio, and i agree with you. Even at non endurance event like a club track day ill prob have it in, thats if theres someone there thats happy to talk to me ha ha, so they can tell me that im leaking oil bad and to come in or i can tell them that im on fire or why ive stoped on the track! So the benefit is better then the weight, it would save the car or my life.
I have several Kenwood portables (hand held) which i use for work, so yeah i have set the car up to use one.
I have my own frequency issued by the ACMA plus also the normal public UHF 80 channels, so can have private comms to the car for endurence events pit crew could be on another frequency.
They have external connections for the PTT button which is on my steering wheel as seen in the pics, and connection for helmet, plus have antenna on the roof - all ways fun drilling holes in the roof.
Being the portable it runs on battery, so if i shut the car down, radio will still work.
If you enter the wakefield 300 or similar again and need pit crew again, im happy to help and can provide some comms.
