I had planned to use the 67 "B" dash but needed several extra instruments plus the tach and Speedometer would not match the RPM of the engine and the speedo would not match the TR-7 gearbox so I wanted to use a TR-7 instrument cluster in the center and decided I would just put a flat dash the rest of the way on both sides.
I made it out of an aluminum sheet that a friend gave me from an aircraft project he had and I glued a piece of 1/4 in. plywood donated by a local cabinet shop. This allowed enough room for the additional gauges. In the radio speaker position I am installing the air control valves and the ignition advance control for the direct ignition system.
Air tank to the far right is a new Freon bottle and valves to control the air to the air start system are being mounted in the old speaker console. I had planned to install the "G-Tech Pro" unit and the MSD Knock sensor display unit next to the air valves but both have controls on their sides. So they will either be mounted on top of the dash or directly under the dash later. The instrument cluster is from a 77 TR-7 with conventional instruments and the added instruments to the right are, Oil Pressure, Oil Temp., Manifold Vacuum, Fuel Pressure and Air Tank Pressure.
The upper dash and dash pad is 1967 MGB. The electrical switch to the left of the instrument cluster is a Master switch to turn all electrical systems on and all of the switches to the right are to operate electrical components like used on the 1967 "B" dash. Relays will be placed close to each component so the switches will not carry the load and only trigger each relay. Only one 12 gauge wire will carry the current to each area of the car and fine ribbon wire (from the computer industry) will be used to trigger each relay which will be located close to each item (load). This will take the current load off of each switch. (A common cause of electrical failure in older British cars)
Major set back, when assembling the oil lines on the oil pump, the welded on fitting for the remote filter and oil cooler broke off. No penetration on the weld. Two alternative repairs failed so a new fitting was made on the lathe and then welded in place with good penetration this time but that also left a lot of extra metal to machine. My friend's Bridgeport was not available so here I am making use of my drill press with a spot weld removal drill as my make shift end mill. Not great, but it worked. Good thing it broke assembling, rather than later running.
So much time, blood, sweat and tears ($) are in this engine that I will install a low oil pressure kill switch to the ignition system. I will decide after I finish weather to install a bypass for starting or just wait for oil pressure to build before it lets the ignition fire. Since it is compressed air that spins the engine to start I will test the time it takes to build oil pressure to see if a bypass start ignition is necessary.
Work progresses on the oil pump and instrument panel. New oil line fitting is welded into the pump and machined. Now it will be repainted and installed.
The instrument cluster is a stock TR-7 5 speed cluster with the face cut back and will be fitted with a flat clear plastic face in place of the original curved piece. The switch to the left of the cluster is a master switch with an indicator LED. The new gauges to the right of the cluster are Oil Pressure, Oil Temperature, Fuel Pressure, Manifold Vacuum and Air Tank Pressure. The electrical switches are for the Engagement and Disengagement of the Air Distributor drive by the camshaft, The Fuel Pump, Ignition System and lights. The turn signal switch and the wiper switch are standard MG mounted on the steering column. The center consol panel has two control levers that are used to turn on the Air Pressure to the system and to turn the Air pressure on to the Engine for starting. More controls are to be installed in that consol panel. A slide control of total Ignition advance, Choke pull cable, Hood pull cable to unlock the hood and a pull cable to lock the hood. The MSD knock monitor LED display will be mounted on top of the dash over the instrument cluster as will the G Tech Pro "G" meter. A fire suppression system control will also be installed in the consol panel.
In the pictures above you will note the clutch and brake pedals were modified by straightening the brake pedal and bending the clutch further to the left. This was to allow more room for the engine. The pedal mounting assembly was already moved to the left which was not enough. The light gray painted section just to the left of the air tank is how far the engine was moved to the rear. Just about the same was done on the drivers side thus the modification to the pedals.
The door striker plate and latch needed to be either replated with yellow zink or replaced as they were very ugly. So I decided to powder coat them and if they get ugly again too quick I will either zink plate them or replace them at a later date.
The Air tank is a Freon bottle and is in the position it will be mounted. A pressure relief valve will be installed to pop off at 250 PSI. The Freon tank is rated at 365 PSI and I will be using 200 PSI as a operating pressure. The engine spins over at 120 PSI (as you can see in the video on Page 7) but the Direct Ignition requires a faster speed to operate, like a magneto. I did get it to fire and start at 120 PSI when I had the engine on a test stand but the spark was sporadic.
Most sports teams have a mascot and I believe my car should have one that represents the essence of the car. I have searched for one all last year and I finally found one that should represent this car. Many car owners display trophies that they have won at events and a few display a stuffed animal in their car. That's cute but this represents the car as best as I could word it.
The car and the mascot should have a name but I have not been able to come up with one I like yet. Maybe "Dragon" or maybe "Dragon 8" as the photo was named. Or possibly "The Green Dragon". A friend stated that it was a good mascot as the car was a "Fire breathing animal that could fly"
