heres a subject i havent seen before. what size fuse/breaker do you guys run in your drag car. i was thinking of getting a 30A for my accessories (pump, lights, fan, starter signal. max for fuel pump is 20A, max for dist is 10A@10k, ECU shouldnt take crap 3A MAX, lights (1-2A) and fan (5A) will be used very little. i was thinking 60A breaker for starter. what do you guys use?

 

I would break the accesories down into individual circuits and switch/fuse them seperatley...

Marker lights (2xFront + 2xRear) should get 10A.
Fuel pump likes 20A.
Fan motor should be happy with 10A.
ECU doesn't use much when VTEC isn't engaged... 7.5A should be fine.
Starter signal should be fine at 15A.
Starter power is usually taken directly from the Battery. A 100A breaker should do the trick if you are looking for safety there.

 

well i still have a "main" going to my master switch then to my fused distribution block so each "circuit" will be individually protected also. just wanted a rough idea of what people were using. its a full drag car so i will probably only have 1-2 lights in the rear and tach/oil pressure/water temp lights. the rest is pretty well broke down. keep em coming.
