I worked on the wing and boot, cut out the inner shell of the carbon/ fibreglass bottom boot lid. Total loss of 1kg, it all adds up in the end.

Also removed the aeromotions computer which weighted 3kg, that is heavy. So in total another 4kg out of the car for the day. We have bets on what the car will weigh once completed, Brett and I reckon 1270kg, dean reckons 1250 and if its not he's gonna cut everything out till he's right. Next week ill start on the bonnet and chop it up.

The whole engine except for the hypertune plenum was cryogenically frozen, from the block to the clutch and flywheel, head, nuts and bolts, the lot. I have no idea if this actually prolongs the life of the parts, but went for it on the engine builders recommendations.

I have heard good things about the cryogen. I didnt think it was worth it personally, but apparently it does make a difference. Got told they put some valves in a vat and they were noticeably harder to machine afterwards.

Did you buy a unfinished camshafts and have them custom machined? how much did that work cost (minus the camshafts themselves)?

nice build man, love those carbon lights.

goodluck hope you make it to WTAC. Looks like you'll be fast!

I hope so, I guess time will tell.

Nah, they are an off the shelf order. My engine builder is secret squirrel when it comes to the cams. Not sure why, they are just cams I say. But I wanted to at least show everyone the specs of em. Edited July 4, 2013 by stevena

Leigh our fabricator and the guy's worked on fitting up a dash today, think ill carbon wrap it.

Wrap it!

Here is an example of one wrapped

[R32GOJIRA]

+1 for wrapping.

You'd get wicked glare from the sun if you dont.

Wouldn't be fun half way through a turn and the reflective light from the sun blinds you!!!

Great build. Interesting read. Personally I would throw some suede over the dash. Help with noise and vibration and look a bit neater than carbon wrap

[R32GOJIRA]

Flocking may even be an option.

[stevena]

Great ideas guys, I even had to look up "flocking" as I didn't know what the process was, have seen it before but didn't know what it was called. I like the dark carbon look wrap, not sure if Steve's is black or carbon black, bit hard to see with that photo but love your dash dude.

[stevena]

Decided on wrapping the dash in matt black as the carbon finish has a glare to it. Dash brackets are welded to the body and the dash attaches to the brackets for easy in and out if required.

[stevena]

Dash weighs 2kg, standard was 10kg, and a copy of the original dash in carbon fibre weighs 2.2kg but cost heaps. Happy with my choice

[Seano350GT]

dash looks great, keen on more updates

[stevena]

Started cutting out the inner shell on the bonnet also, was weighing 9.5kg, now weighing 7.5kg, 2kg of inner shell.

[stevena]

Blocked off the rear vents to the bonnet with some carbon. They were allowing air in to the wrong area.

[stevena]

Changed the steering bush to a solid bush, driftworks. Also repairing the driveshaft as a boot was split

[stevena]

Carbon doors with plastic windows weighing 8kg, I can't decide if I should cut up the door also, I can get another 1.5-2.5kg out of them, cut or leave?

[R32GOJIRA]

Could you not have utilized the vents on the bonnet to divert air through some ducting to where needed? Or too much hassle?

Cut em. This is balls out, every little bit counts.
