Yes the rockwool does add some weight but i have only used the rockwool on the centre section of the bulkhead as it will handle more heat there. The rest of the bulkhead will be different. Total weight of the insulation is is no more than the 2 quarter windows.
I am hoping for a 50% reduction on noise as this is a road going car after all. Dont realy fancy me and the g/f sitting at the lights with a set of coms on. Done a 70 mile trip in the summer and me head was ringing with the noise. Ear plugs are no good either not when your listening for nuts and bolts comming loose and things falling off :'(

Just a little bit more progress. Some final adjustments to the flip hinges and starting to add the bright stuff and also a taster of the interior. I also added a small clue to what engine it has. And the 3mm foam rubber is really light weight honest.











The rear hood hooks on at the front and will be held down at the rear with bonnet pins.
The hood is easily removed for track days and side windows opened for some cool air.

Done a bit more over the last few days (Full time build only 8 months so far lol)





Decided the head lining looks absolutely dreadful so I changed it. It was also splattered with grease when I lost the grease nipple from the diff travelling at speed.

The steering wheel is quite small and a un-drilled type. The boss was a problem, I don't like the quick release ones as they are pointless and to expensive for what they are. So I made one from a mountney boss with a bit help from a lathe.

Oh and there's more. Started perfecting the dash, its going to be flocked in black and the demisters done in flat black paint.
And there is loads more switches going on. Due to de stalking the column.

Koss, Words Fail Me! This Is Possibly The Best Z-Cars Example I've Ever Seen, And It Isn't Even Finished...
My Hat Goes Off To You, Great Build. You Lucky Fu#ker

Does look fantastic!

Thanks for the comments.

[MiniKid..]

Just read the whole thing and this is defently the best zcars build on here!

could i have some info on the blue headlining and the heaters. Also what fastners are you using for the flip front?

Cheers,
Carl

Hi thanks for the comments, the blue headlining is no more than rags now. The black foam rubber is more appropriate for sound acoustics.

Fasteners on the side of the flip front are 6 x dzus onto the A panels. And the hinges are a top secret

Heaters are available from car builder solutions (like 12v hair dryers).

Got to say, this is definately one of the best I have seen, well done mate. I will be happy just to get mine running :) Congrats and keep it up!

Just a little update,

The sound proofing is absolutely amazing, I was hoping for a 50% reduction in noise and think I got more.
The only noise I get now seems to come from outside the car.

I also found time to look at the reverse staling problem, with a few surprises.
A large capacitor was fitted with + and - connectors. The cap is fed via a 6 amp diode from the +ve side of the battery (the diode being like a one way valve). So if the battery had a sudden voltage drop the cap would store 12 volts for a period of time.
The cap then supplies power to the ECU/ignition sys/injection sys.
After wiring every thing up I put it to the test. Set the idle @ 1800 revs to start with, hit the reverse and guess what? it stalled just like it did in the first place.
Out with the meter.
1 Test voltage on battery and note voltage drop when hitting reverse. Voltage drops down to 3 volts then rises to 9/10 within a second.
2 Test amps used by ecu/injection/ignition. Only 2 amps. Thought it would have been more.
3 Test voltage to ecu/injector sys/ignition while hitting reverse. Hey it stays 12v. So something works.

Going to wire the fuel pump to a separate battery tomorrow and see if the problem lies there.

Some pics off the mobile phone.

Had a look at the reverse scenario again today. The fuel pump draws 5 amps. I temporary wired the fuel pump to a separate battery and guess what it still cuts out in reverse.
Final decision I now have a motor bike battery running the engine and fuel pump. And a mini battery for reverse, lights etc and starting.
I can now do a 3 point turn without cutting the engine and it don't sound like a tram when the engines running.
Back on with the build.

[markrally]

If you carry on adding any more weight like spare batterys and sound deadining it will only be as fast as a tram!!!

When is it going for mot?? and then for sale?

Any progress with the monte?


Cheers

But you can take the big one out for track days. Mot and for sale end of April.
