Remember, when you do this it MUST be done
so it is PUSH to SHUT IT OFF. That is a rule,
so do it right the first time. I will attach
a cable to the other end of the rod so I can
turn the power off or on from the driver's seat.
I think this is an important safety item and
you should consider this as well. If you have
a major electrical problem you are likely the
first to know it and if you can instantly kill
the power without unbuckling and going to the
rear of the car you might save a lot of repair
time and some valuable parts.

This is the finished
electrical panel. The MSD Programmable Digital
7 ignition box and remote Programmer are
there along with the main cables from the
batteries. I like to ground everything to
direct to the battery through a main cable
and this makes it easy. If I ever need to
add something it will be a lot easier as
well since the main power cable is right
where you need it. The Moroso switch panel
was easy to mount with a small piece of
1-inch aluminum angle and will easy to reach
and still out of the way when we are racing. |
This is how we mounted
the required master disconnect switch. The
rod attached to the handle with a small
bolt and lock nut (make sure it doesn't
bind up) and a black knob from a local hardware
store was put on a small piece of steel
rod that I cut some threads on to attach
it. The rod goes forward from the switch
and will attach to a short cable I will
locate next to the driver so the battery
can be turned on or off from the driver's
seat. Make sure your outside disconnect
rod or knob is PUSH OFF, it is an IHRA and
NHRA rule. |

Close up of the
way we used the handle that came with the
switch and attached our rod so we could
have a knob outside the car and one in the
driver's area. Nothing trick, just some
thought and a couple bucks worth of hardware. |
I made my own fuel pump brackets out of some
scrap steel. The bracket for the master switch
was bent up in the vise and the mount for the
Moroso switch panel is a $1.00 piece of aluminum
angle from a lumber store. You can make a lot
of very functional parts in your garage if you
just give it some thought. It is a great way
to save a bunch of money and put some pride
into knowing you did it yourself.
I have just about completed the fuel system.
I drilled out the fuel cell to accept a new
#10 AN outlet and I have decided to use Aeroquip
Socketless hose and special fittings for the
plumbing. This hose has 250 psi pressure rating
and is totally resistant to race gas,

alcohol,
transmission fluid or oils. It will save me
about $400 over using stainless hose and the
appropriate hose ends. That money will pay for
new slicks and the fuel system won't know the
difference.
We are going to start out running race gas
and to that end we wanted to start with an electric
fuel pump. We chose the A2000 pump from Aeromotive.
It has more than enough volume for us and has
an adjustable bypass so we can control the pressure
going to the regulator for either gas or alcohol.
We decided to use a relay to power it with for
a couple reasons. If you use the switch panel
to turn the pump on and off, all the amps go
through the switch and it gets worn out quicker.
In addition, you are trying to pull the necessary
amps through the small wires coming out of the
switch panel. With a relay installed back by
the pump, all the switch is doing is signaling
the relay to turn on and off the high amps needed
to run the pump. I used a readily available
30-amp relay from Radio Shack (cost about $7.00)
and will make sure the pump is getting full
power all the time.
