I came to the same conclusion, there's no weight to be saved on a Macpherson strut, the loadings are massive. What sort of piston size are you going to - 41mm?Quote:

Hopefully solved the problem of the air filter, with a bit of modification to the bulkhead area and a Reverie carbon fibre airbox, which will be bonded to the trumpets, rather than attaching direct to the throttle bodies;

I need to sort out an air intake hose to the front bumper, as well as a remote air filter.
Original NickJ wiper motor now ditched (and for sale soon);
http://i285.photobucket.com/albums/l...ps6rmyq25s.jpg
I think I'm going to locate the lightest possible rear wiper motor from some other car, and mount it THROUGH the windscreen (i.e. inside the car). As the screen is polycarbonate that should work. Most of the modern rear wiper motors seem to pass through the glass of the rear screen.
Awesome inlet! I always fancied something like that on my old one, just couldn't justify the price tag lol
Love the Airbox Colin ,it's a bit better sized than the one I have ,bit out of my budget though ��
What's the clearance from the radius on the trumpets to the back wall of the airbox? I recall studying one of Dave Vizards publications that showed the effect of not having enough space around the trumpets and what it did to your airflow/power delivery. I don't think it's been published on the internet, so I can't offer a link to it (yet). Looks good though. And as for the windscreen, yes - drill carefully, go up in small increments. I fitted one to my ASCAR (V8 American Stock Car) that I used to race at Rockingham on the oval back some time in history.... The screen on that is made with coated Makrolon (the stuff they use on ships wheelhouse windows - so is tough!!), and it drills nice starting small. If you try to drill too big too quick, it'll snatch and likely crack out from the hole.
Excellent advice, thanks.Quote:

So I would be interested to learn what would be best. I have 90mm trumpets,and a relatively shallow airbox, so I may not be able to achieve perfection and still get it under the bonnet.
Jezz - I was lucky and had this Reverie airbox on the shelf for years. It came up on ebay badly advertised, and I got it for a very nice price :).
I've had a dig around, and there are a number of schools of thought. One is 1/4 the diameter of the intake - BUT that can affect wave reflection which can affect peak torque.
Another one states that you'd need 1.5" or more, otherwise you'll lose peak power at higher revs. The basis is "as far as you can" that way you don't suffer any affects. The same applies for "behind" the bellmouth - so it's more or less in clear space.
Difficult to do in the confines of a Nova engine bay, though you've chopped out a bit of the firewall, which would have you more space for a deeper box.
Many thanks, I've got some 3M epoxy to use for bonding in the trumpets so I will see what I can achieve.Quote:

Fortunately you are allowed to make modifications purely for the intake system, so I can get away with that.Quote:

A little more playing about with the fuel system.
A new swirl pot (the 3rd one, and I am now happy with it), plus the high pressure fuel pump is now fitted and piped up.
The fuel tank has now been modified and I shall be collecting it from my welder on Monday, so I will post up pictures of it then. He's ex-Prodrive, so it should be good :)

Does it run two pumps?
Yes, there will be a low-pressure fuel pump located down by the tank.Quote:

Some nice fab work on the tank Colin, you must be very happy with it.
When are you aiming to compete then this year?
I'm still hoping for this year (albeit the hillclimb season ends around October), now I've got the fuel system sorted the list is getting shorter.
Main things outstanding now are ;
Clutch release system (still playing about with hydraulics)
The pedal box needs fitting and plumbing up, as well as a throttle cable making
All the new switchgear inside the car needs wiring up, together with wiring for the new fuel pumps and the battery
I am still waiting for the MBE new dash display system to be ready - SBD promised I would have it for the end of April, but there have been delays in production of it (it's a new design of LCD display). Stupidly I sold all the instrumentation I raced with previously so I could afford to buy this new display, and didn't have a contingency plan for delays.
Patience is a virtue ;)
Very true, and this is what I'm waiting for;Quote:

Are you putting any form if isolation between mounts and the tank?
Thanks Ben.Quote:

My Nova is currently away for a while, with a friend who is doing some work on it for me. The wiring loom is now all done, hoorah.
And another friend has just finished doing modifications to the radiator and mountings for it;

Not surprisingly, I am delighted with how this has turned out!
Looks very nice Colin
Oooo very tastey!
Looks very good but the alloy sections welded on the ends of the inlet and outlet look to have quite sharp edges which may damage your hoses if clamped onto....
I'm ahead of you there Ben.........they are welded on ferrules on the ends of the pipes, ready to accept Wiggins connectors;Quote:

All coolant pipework will be done in solid alloy pipe with these connectors. No more silicone hose and jubilee clips I hope!
Noting much to update, apart from the acquisition of some split rim wheels.
I have absolutely no idea whether they will fit (in terms of width), but I couldn't resist them as they are a lookalike of the Speedline wheel found on one of my favourite cars, the Lancia 037;

They were originally made for a racing Imp;

They are very cool.
That IMP is very cool
It certainly is!Quote:

Trial fitted the rear wheels today on a spare Nova race shell (wide-arched) that I have, and it's clear they are going to be too wide. I thought they would be at 8" and with a lot of offset;

Can you not just go extra wide arches? Red shell looks cool.
I could, but I wasn't so keen on adding more arch at the back if it can be avoided.Quote:

Ah ok and i always keep my eyes open on what you're selling.
Colin are you sure that the arches on Graham's car are proper wide arches ,I seem to remember them not being as wide as my standard wide arch kit
That's a good point Jezz, they may not be as wide as those on my car. But I can't check as my Nova is 250 miles away from me!Quote:

I wondered where Graham's Nova had gone.. now I know... His "wide body" isn't as wide as some of the rally-x kits, and no where near as wide as I'm planning for one of my future projects.
The wheels - did they come from Col Rooney?
