Bonnet Bulge/Scoop ?

So, I have fitted the zetec and am nearing the point of covering the parts of it that I have to cut the bonnet and nose cone for clearance.

What have people used within the 'locost' rules

The scoop or bulge needs to be greater than 290mm wide at the front, but no bigger than 350mm, the length needs to be greater than 200mm and the height needs to be 40mm.

So far I can't find anything close to these, everything seams upto 250mm wide or over 400mm ?

Thanks for any replies.

Is this an Aluminium or Fibreglass bonnet?

I've recently raised my engine by 25mm and it used to rub on the underside of my bonnet in the old position. So I'm pretty sure I shall need a bulge in my Aluminium bonnet before I can re-fit it.

My plan was to anneal the Aluminium and then slowly and carefully 'beat-the'sh1t' out of it to form a lovely, smooth bonnet bulge that covers the engine and allows the bonnet to be fitted to the Scuttle, Chassis and Nosecone. Just like it did before I raised the engine.

That's the plan - I shall see if it works soon

Donít know if this one fits your sizes. I was looking for one as well after changing from single Webber to bike carbs. Now have a hole in bonnet where K&N filter used to stick through.

Thanks guys, my bonnet is f/glass and I've had to cut a long hole for the air filter and it also has to clear the top of the front carbs too, but I think I've got that issue covered, well the carb tops are not sharp, and I've put edge trim on the air filter brackets.
Sadly most bonnet scoops are between 200 and 250mm which is too small for my zetec clearance. I think I'll need to get a 400mm wide one and then cut it down to suit.

Easy enough to make your own from GRP.
I made mine using a card former then took a mould from that and laid up the final shape starting with a gel coat.
Most GRP suppliers offer starter kits or will pull one together for you if you tell them what you're after.
GRP takes a bit of practise but it's cheap enough to warrant a few trial and error moulds to achieve good results.
