That is an ideal size for the oil pressure gauge. If it comes on during a race push the clutch down immediately and switch off.
Thank you, that's good advice, I will make a note of that.
I notice you only have one fuel pump switch. Is that because you only have one pump? Personally I like 2 separate electric pumps piped in parallel and individually wired & switched for reliability, but it's personal choice really.
Ah, no that's not my car - it a picture I found on google. My understanding is when plumbed in parallel they provide increased flow but at the same pressure? I guess you have two pump for redundancy rather for flow?
It comes down to personal choice at the end of the day I guess. An Ammeter can be helpful, but as the others have said, a Voltmeter is probably more useful.
Long ago, I used to have an almost full 'Smiths Catalogue' fitted to the dashboard, now I couldn't care less, I have a Buzzer on the Oil Lamp and a Clock so I know when it's lunch.
Haha I'd not even considered a clock!
