So much detail and care going into this build, hopefully it'll be moderately bug free when you go for your first drive. I can only think of 1 other build that was more involved than this one (and it wasn't mine!).

Thanks nev. it takes a surprising amount of effort and detail to keep things as simple as possible. Hopefully through simplicity comes a degree of bug-free ness. But hey, modified cars. Could explode. Roll the dice!

Sikaflex cured overnight, so pipework is now holding its own :)

Final layout now clearly visible. Needs some hose clamps but is pretty much finished :yup: it's all pretty compact when you consider how much pipework for the whole system is packed in this tiny little engine. 4" intake, 3" intercooler, 3.5" dump pipe etc.

Neighbours are home for the Xmas break, so no garage access for me till they're gone again. Need to find something to work on...

First time it’s really be revved, and seemingly lots of condensation in the system! :lol: plus it’s about 2deg at the moment. Might let it warm up more next time...

Knocked a bunch of small shitty stuff off the list. Amongst other invisible and relatively unexciting things, I finally got the tablet-based dash hardwired in. The galaxy tab seems to require a tonne of amps to sustain charge, so sourced a 3A usb 12v adapter and according to some current app seems to pump out a reliable 1800-2000mA. Had to attack the wiring behind the dash (which suck dicks) and splice in a power supply. But happy days! Have race capture, real dash, track addict and dash command running (actually bought apps!). Was happily surprised to find the paid version of real dash has map navigation built in too, which is unreal. Really worked out well :)

Had a couple of hours off work today due to a massive city wide power failure which destroyed our IT dept, and shut down pretty much the whole theatre complex and took all our systems offline. Thanks blokes... I'm going home.

So made a thermoplastic mould of the roof scoop, and finished glassing it up last night

IMG_3454.JPG

popped the plug out (popped being a very generous term for busting the fcuker up into small chunks) and am super satisfied with the result. its a complex compound curve which is a PITA to photograph, so forgive the 11ty pics, but im very happy with myself. symmetrical flowing curves :) the transition of the roofline curve into the duct actually works easy on the eye despite the duct opening being relatively huge. aerodynamically it'll work too. might be a bit of floor separation but i can live with that.

glass filler and a bit of blocking tomorrow, then ill give it a hit with poly 2k spray filler

Silk Cut Scoop - filled, reprofiled, blocked smooth and cut to final dimensions :)
 
It’s a PITA little thing to try and show in a pic, so here’s a short video to give a bit of 3D. It’s huge!
 
 
and some pics of the same thing, because, well, can never have enough pics

and for something a little different...
 
decided to splurge on a race capture pro (got one cheap on facebook) and as an offshoot of that, decided their tablet based dash option (bluetooth) was worth having a play with.
 
after a bit of googling, found the samsung galaxy tab 3 8" was the best fit for physical size whilst maximising the screen size in the available space (and also dirt cheap second hand on scumtree). the lotus/vx binnacle makes this kind of thing p*ss easy too... the used tablet i got came with a shitty case/wallet thing, which i removed the plastic click-in holder part from, epoxied some aluminium box section to the back of it (as a spacer basically) and stuck some 3M self adhesive velcro to both the binnacle and the tablet mount. tough as nails, and not coming out in a hurry (does, in fact, not come out in a hurry - levering/peeling the velcro out in the available space is pretty tough, so once in, its pretty much staying in till the one day youre determined to take it out). i know nothing about android tabs, but the possibilities to get it running semi autonomously seem pretty good too: https://wiki.autospo...blet_Automation need to get my nerd hat on though, and maybe learn something to implement that. 
 
these pics are some random lap timing screen of the race capture, but you can obviously also run OBD dash gauges, or literally any of the 100's of OBD based gauge apps. pretty neat and simply really, and very happy with it :)

Hah, I did almost exactly the same with my RaceCapture Pro, an additional Analogue->CAN converter for some additional sensors and their GoPro controller a few years back. Though I cut a slot in the top of a sacrificial binnacle and just slid the Amazon Fire 8" into it in front of the OE cluster. Worked pretty well but the reflections from the glossy screen drove me nuts and then if you wore sunglasses (was a sunny run to Zandvoort initially) the polarisation meant the screen was almost blank. Still got all of the stuff sat in a box, never used since, somewhere in the study after that abortive trip. :s

Probably less of an issue with a hardtop or any roof on the car anyway and at the very least it would have helped, if not sorted it. Given it was only really a quick lash up and more of a proof of concept and I've probably only driven the car once since in the intervening years, I never invested any further time or effort in it.

 

I do hate glossy screens though. Bane of my life.

Couple of work/kid/wife free hours. Had a crack at getting the diffuser bock shaped up. Max outlet angle now 28deg

Curves need a little fine tuning, and the sides are going to need some creative 3D thinking, but all in all happy with the form :)
