and then need to make up covers for wiring and heater hoses.:

and fitting body panels and checking shut gaps...

I have also filled engine with oil and run the dry sump pump with electric drill to check for pressure and oil leaks...
all good...making 80 psi...will need to adjust when engine is started...
Clutch hyd filled and clutch checked / bled...had a leak at the crimp of pipe to adjuster...so cut off and made up new joiner with extension.
Checked clutch works by slowly turning engine over with spanner on crank while in gear, checking output shafts turn and then slowly pressing pedal until shaft stops ( clutch disengages ) then pushed pedal down approx another 1 inch and set the stop point adjuster. do not want to go too far and push centre release off its end !!
Filled up gear box with oil.
pressure tested the coolant system with air before filling with coolant...had a couple of hissing leaks at point where my manifold plate bolts to head instead of mechanical water pump....my mistake...no gasket...rectified
now pressure tested until cap blows off into overflow tank about 20psi....then held pressure for 30 mins....so no leaks...yet...
finally fitted bundle of snakes and silencers.
Next job(s) is to fill with coolant, programme the ecu with engine parameters, fill with fuel, check pumps work and no leaks, check got sparks and then go for a start.......
planned for next week

Bravo Jerry ....... she runs !!!!
I expect to see progress on Christmas Day ..... there's no time for slacking now! A concerted effort and you could be on the road by the coming summer.
Looking ahead, if you plan on going to the AK Open Day in the Spring (even without the GT) then post on here as it would be nice to say hi. Ditto with Chris who is posting pics of his build.
Cheers
Steve.

Hi Jerry, just caught your build for the first time and your seats got my attention. Depending on your height, you may want to consider not installing conventional seats, rather follow the original design ethos. Fabricate a set of brackets to hold a minimal seat base and a separate seat back, both pieces as minimal as possible to maximise the cabin space for you.

Thanks for the suggestion Martin..

I'm not the tallest person and my brother in law ( other driver ) has long legs but body height similar to mine.
With the bubbles fitted we both can sit quite comfortable with helmets on.
Me with the seat slid forward and brother in law with seat slid back.

Jerry, something to consider that I found useful as a taller (6’1”) builder…I changed the angle of the seat with more reclining back by fabricating a front riser that bolted to the adjustable rails. This made it way more comfortable with longer legs as my thighs had more bolstered support from the seat base. So much better that I even had to bring the seat forward a notch from the previous most rearward position.

Thanks Devin,

Yep.... That was exactly what i did.....
but could not tilt too far back as back of seat collided with rear bulkhead when brother in law sat in it. seat max backwards on rails.

both sides now all finished...
just have to carefully remove and seam tig weld all joints...
just hope it does not move too much and all aligns after welding...

Hi there Jerry41, I am building the same thing with a 3d printer. Your Build looks awesome. I use Ai to help with my build and it says 2 things cyl 1 to passenger collector or it says cyl 1 to driver collector tube lengths, I am building the same thing with a 3d printer.

looking good...
remember to make room to be able to remove spark plugs !!!
I will do a drawing and explanation of header / exhaust layout later on today.

layout below

looking towards the REAR of gt ( looking into collectors )


o4 o6 o3 o8

o1 o7 02 o5

numbers depict cylinder numbers

SBF
1 2 3 4
FRONT
5 6 7 8

FIRING ORDER : 1,5,4,2,6,3,7,8

The connection to the collectors allows every exhaust pulse to alternate between collectors.
also if you follow the firing order sequence you will see that there is a rotation / swirl effect.

Hope this is of use
