Thats insane! There isn't a lot of door left though. Why do they allow metal removal like that but dont allow removal or modification of metal around the seal areas on the rear windows or modifications to the bulkhead / battery area firewall?
It's all to do with what is classified as the 'monocoque'......i.e. the main structure of the car which is made in one piece.Quote:

The overriding rule is that you are not allowed to lighten the monocoque between the centres of the wheels. Hence my bulkhead remains completely standard, and part of the spare wheel well is still there at the back.
Colin,
I've looked at the pics of your "spin", and I'm thinking that it's probably due to your wheel on the grass - and your new fierce plate diff. It probably "snatched" and that led to what happened. When I put new plates/springs in my diff, it always got snatchy, and the only answer is to be brave and keep your foot in!! If you lift, it bites you in the bum!
I also note that your ride height is tail low. I always found that that made any of my cars tail happy, far from balanced/neutral. After having mine set up professionally back in 1991 (eek!), it was always tail up, only a bit, numbers in my little black book (and my head).
Back to the weight of the car - what's it down to now?
Yes, it wasn't until I got the photographs through that the reason for the spins became clear! The new diff is so twitchy it was pulling me way over to the right hand side of the track, and onto the grass. I'm sure it's just a question of me learning to drive the diff, and I'm equally sure that ultimately it will be faster, but having been used to the Quaife ATB it's a bit of a shock! But everyone says the same that plated LSD's are evil to drive with, so I certainly expected it.Quote:

As for weight, it's currently 541kg, but is set to gain a couple of kg soon, as I'm going to fit an alternator as I am fed up with the battery issues.
Is the door Steel Colin?
What's left of the frame is steel, the skin itself is aluminium;Quote:

Time for a bit of an update.
The exhaust system is now off the car, and is with a local exhaust fabricators who are going to make it in aluminium for me, which will hopefully save a Kg or two, and it'll be slightly larger to hopefully allow it to breathe a little better. It's a bit of an experiment, as aluminium exhausts aren't commonly used, but my research suggests it should be ok.
As mentioned, I have decided to fit an alternator, after successive problems with lightweight batteries. So I've acquired this alternator;

And this lower pulley, which looks like it should be a direct replacement for my current one (I hope!);

I've had a bit of a leak from the gearbox, which seems to be from the diff cover, so I've removed the cover to check it's all true, and got a new gasket set to go on. I'm taking the opportunity to swap the old diff cover for one which has a drain plug in it, to make future maintenance easier. Note the Straight Cut crownwheel in the gearbox;

Just as a precaution I got Magnecor to make me up a new set of HT leads, which look rather nice;

And I've picked up a few sheets of 3mm carbon fibre, which I reckon can be fashioned into rather lovely front and rear towing eyes;
http://i285.photobucket.com/albums/l...ort/013-31.jpg
And finally I found a Corsa VXR engine with exhaust manifold and turbo, so I can work out what's feasible in terms of future engine developments. Might be a long while before I can afford to do that though;

will you get that past the scrutineers, isn't the rule that the block must be from the original model?
if yes, then it will be a truly awesome device.
The scrutineers would only notice if it's protested by another competitor.......and that's bound to happen, so wouldn't be worth the risk/expense.Quote:

So, if I am going to progress this plan it would be dependent on being able to use the VXR head on a 1600cc 8v Nova block.
I was hoping that the VXR block would look the same as a Nova one, but it's totally different.
Tap an E16 engine number into it... that would make it externally identifiable as an E16 lol
I had heard they use the Z18XE head, but that's actually entirely different, looks more like a late X16XEL evolution.
Why the VXR head specifically btw, an x16xe head would fulfill the requirements?
those extra chunks sort of mess it up..
didn't tom reid fit all the mucky bits into a 1600 ecotec?? you could get round it that way, as the 8v block fits the 1600 head.
the 1800 heads are streets ahead (‘scuse the pun) of the 1600xe variants, 5mm valve train as stock, better port design and angles, and the breathers are cast internally to the block so fitting one to an earlier block is not so simple as the head gasket faces are quite different as i’m sure you can see colin
you can fit all the 1800 crank/pistons etc into a 1600 block but you will need to machine the crank case to clear the crank webs/rods at half stroke
Nothing much to report on my car, so I thought I'd post up these photos a friend took when he visited a Berg Cup hillcimb recently;

That looks epic
Is that a custom bodykit? Looks awesome !
that looks epic :)
these berg cup things look amazing, ive got a few dvds in the house. Quite a few Novas (corsa a's) run in. The Risse motorsport Kadett is amazing!!!
Hasn't there been a video posted of that recently?
Hillclimb fans on you tube, some great videos/cars on there
Some links to vids of the car in the thread below. Its one of the only Corsa A's competing in the Berg Cup.

you got any ideas/plans to take from this car Colin for your own ?
Not really, I do want to get a front splitter, but that will be all.Quote:

My mate was there also, and also felt the need to take some photos of it and send it to me. Unfortunately this was crashed early on :(

^Aaaaaaaw, it looks like a frowny face :(
Sad times :(
Anyone got anymore info on the car ? Build thread ?!
Noooooo absolutly gutting to see it trashed!
Oh nohes! I'm sure he'll have that fixed before the summer's out though. At last a proper airbox on a humble nova; no wonder it sounds so good :)
Wonder why / how he crashed?
who knows, but most of them fall off the track due to slicks and damp/wet tracks added in they give it 110percent effort lol!Quote:

Still messing about with fitting an alternator, I'm going to have to get a new crank pulley machined up (using the standard GM pulley would have meant moving the crank sensor, which I didn't fancy).
So I took the opportunity to change the alternator pulley from a 'V' belt to a multi-groove type, which are less prone to getting thrown off at high revs;
http://i285.photobucket.com/albums/l...ort/001-55.jpg
http://i285.photobucket.com/albums/l...ort/002-91.jpg
The new pulley is aluminium, and the retaining nut is titanium, so a useful weight saving as well.
Just been to see this in action, really impressive car on track. Colin narrowly missed taking a first in class spinning on the last corner on what looked to be a very quick run. Definitely has the potential to beat the quickest of the mini's now!
i hope there are pictures or maybe a video coming shortly ?Quote:

Wanna see it run I highly recommend getting off your lazy arses and getting to an event as it was pretty damn good, huuuuge variety of cars running :) Back next month! :d
But you never bring anything to a show Mark lol your Nova lives in lots of boxes lol
No idea who took it, but I just found the video!;Quote:
