Hi Simon,
Very impressive project.
I'd like to ask a couple of questions, hope you don't mind...
Is the breather box simply vented to atmosphere through the big bore black hose?
What are you doing with regards to the space previously occupied by the boot floor panel?
Cheers,
Moray

Hi Guys, Q's welcome 
Boot floor will be more 2mm ally checker-plate, I have a US "Jaz" fuel cell to go in there as well as a 2 gall water tank (and the battery)
I wanted to make it flat to aid fitting all these parts, also to be able to do something with the underfloor area aero wise (in time...)
Breather currently vents to atmo through the big hose, when I get a length of 25mm ID i'll take it right into the chassis rail.
Just need to get the intake "box" done now, that will then cover up the (large) hole in the inner wing.
I have also decided not to use the ABS for the time being, I like being able to turn it in on the brakes and that is not possible with the EBD system, I do however, reserve the right to change my mind on this at least another 50 times...
Cheers
Simon

Lol! What's the score with the slam panel and vertical stiffener Simon? It looks in a couple of the later engine bay that you've cut the slam panel away between the headlights (or is there a piece of something black laid over the top?).
If you have cut it/them out, what was the reason behind it, and has the front of the car gone a little wobbly without them?
BTW, FWIW don't blame you on the ABS decision. Don't like it - for the same reason you expressed.

Slam panel and vertical are no more
space is needed for the intercooler / rad / condenser configuration.
Seems ok, not too wobbly, maybe needs a little stay each side, but we'll see after all the bits are in.

You can use just about anything for that. I got an extruded aluminium box (designed to hold a piece of electronic equipment) from Farnell. A bit of work to seal the ends and fit the hose unions in, and it looks like it was made to do the job. Much cheaper than getting one custom fabricated too.
Hi David
Yea, Alex @ AH Fab, top bloke, made to my drawing (ummm, make that back of a *** packet sketch...)
Well gutted at missing scooby shootout, just too many bloody jobs to do in too little time. On the upside at least I have a boot floor now
Will add some more piccies tomorrow

Well that was interesting 
Took my car up the road with our MicroSat timing gear attached to it and did a couple of standing start 0 – 100 and 100 – 0 test’s. I’ll put the txt files onto my www site but suffice to say I’m a bit gutted not to break the 4 / 10 to 60 / 100 with the engine still std, I’ll try a couple more tonight as I got a lot of wheelspin on the first run and bogged on the second. Then I'll start tuning it
Figures so far: -
0-60 4.16 and 4.15
0-100 10.56 and 10.57
¼ 12.90 and 12.85
100-0 4.39 and 5.08 (rear’s locked up on second braking run)
Must try harder!!
Cheers

I'm more cheerfull about the times now
I was well gutted not to break 4 sec's to 60 and 10 secs to 100 though! Went out last night and got the 100 time down to 10.26 but it's a bu**er to launch. Never mind, start tuning it instead
