DIY 8 stack injection system (Track day Manafold)

I decided to make a track day manifold for my XR8 tickford. So I drew up all the manifold plates and had them lazer cut this saved an enormous amount of time in the good old days (after Dinosaur's and before TV) we used to drill and oxy cut 3/8" plate and spend hours grinding and filing to finish the plates there is none of that with lazer cut parts, but you must be accurate with your drawings and measurements.

I obtained 8 x 38mm throttle body's of the Internet they had to be modified and have some appendages removed but they worked out just fine. The manifold was tacked together and very slowly welded 1/2" at a time to avoid warping and it worked fine, only minimum grinding was required to the manifold head faces to be perfect. You will notice I have incorporated a common vacuum manifold up the centre to accomodate MAP, IdleCS, and fuel pressure regulator attachment points.I will be installing an EZEFI Modular self tune ECU (as used by Inglese 8 stack system) http://www.ezefi.com/ I had a lot of fun making this system and look forward to the challenge of making it run properly for track days,

Front compartment lay out trying to retain sort of boot area!

Gear Change system, and dash instruments

Day racing 8 stack fuel injection

Progress July 21st front compartment & Brakes

Tail lights and rear vents

Progress March

Suspension progress

All suspension parts have been painted and assembled, all newly overhauled Corvette brakes rotors & callipers. The gear change main tube lever is complete, we are still on the trolley and will stay there but we are now a rolling chassis.

The peddals are in

I have just mounted the Pedal Box after some modification. but it all worked out in the end. I have begun on the Instrument mounting into the dash.

Special muffler Idea

Well I thought I would have a go at a special muffler. The theory double tubes per side in the muffler to 1 to double the noise absorbtion area. Halve the gas velocity. so more time and area to absorbe the noise. Will it work ? We will never know until some bunny tries it?

Progress after returning from Perth

With appologies I am still learning to Blogg but here goes.

Well I got my old mate Henry to help me pick up the BCU with a hired trailer, we encountered some difficulty when we arrived home with the work stand I constructed it was a bit on the light side but with some Mods and new wheels it is now serviceable. the first thing I had to do on arrival home was squirrel away all the parts supplied by DRB as we are in quite a small unit I now have parts hiding everywhere. I removed the front and rear body mouldings and have put them out in the weather to cure this is necessary to stabilise the new fibreglass.Well I got my old mate Henry to help me pick up the BCU with a hired trailer, we encountered some difficulty when we arrived home with the work stand I constructed it was a bit on the light side but with some Mods and new wheels it is now serviceable. the first thing I had to do on arrival home was squirrel away all the parts supplied by DRB as we are in quite a small unit I now have parts hiding everywhere.

The first Job I did on the BCU was to finish and install the fuel system, Tanks, Filler caps, Scavenge system, fuel gauges, pick ups, Primary Pump, secondary Pump and surge tank return lines and sub frame covers. Then I had Lunch!

The next project was the Air conditioning ducting (yes they are Air Conditioned as they do not have wind up windows) including Windscreen demisters and steering column mount. The under dash evaporator fits quite well but is fiddly to get right.

The wheels have arrived from England and now have the tyres fitted and balanced and look great. (See pic's) . The pedal box arrived complete with master cylinders. and is well on the way to being installed.

I have just discovered that the rack and pinion I obtained by default is the wrong one I managed to pick one up in Sydney so we are underway again with the steering.

My peddle Box arrived from the UK
