My engine used to have a down-draft Weber carb on it, so it needed a nice big air intake bump on the bonnet.



Now that I've got bike carbs this bump is totally redundant, so I'm looking for useful suggestions for how to replace it. So far I've thought of:

1. Take it off, weld in a patch. Wouldn't work due to distortion.

2. Take it off, rivet/bolt on a patch. Would look 'orrible.

3. Replace the bump with a much lower one made of aluminium... little more than a nicely-shaped bit of sheet. This is the solution favoured by Paul G (907), but he's better at ali bashing than I am!

4. Replace the bump with a much lower one made of foam covered with GRP. My favourite solution, but I'm not sure how it would look.

5. Replace the bump with some form of grille, which would be useful to let some air out after it's been through the radiator. Anyone know of a fairly large grille that may be suitable?

6. leave the bump. I hate having stuff on the car that doesn't do anything useful.

Any bright ideas?

If you decide to get rid of it and flog it will you let me know please. Cheers Rich

New bonnet? Mines G/F so it was easy to patch and respray, so much nicer without

re-place bonnet????

Cut a symetrical hole opposite and cover both with mesh from behind thus providing a nice bit of extra ventilation.

Turn it around and put an lcd screen in the hole.

^^^ Like that
I would leave it. It helps cool the engine if nothing else and looks pretty cool

got to agree with the above, id just leave it, looks quite nice

Best left in place - it probably channels more cold air into the engine bay than it would as a plain, flat grille.

Plus, it just kind of looks right with the brooklands screens and ali body - a nice classic style

Leave it there and make a plenum to direct cold air at the carbs, maybe a little forced induction at higher speeds.

That's a thought - wouldn't be difficult to make a duct to take air down to flow across the carbs (they're now on the driver's side of the engine)

Hmm... I see a project looming!

There are some excellent 1 day wheeling courses around....



and they aren't that expensive.

leave it on i think it looks neat and will save you work if nowt else.

I'd just make a new engine cover. I think these cars look so much better without openings or bulges in the bonnet.

Personally I would probably paint it black and make a guide below to feed the carbs cold air.

I think it'll be a bit plain without something IMHO. Louvres in a metal bonnet always appeal to me.

I'm a fan of the outlets idea, either one or a matching pair, remove rad heat and relieve pressure under the bonnet too.

If you have a need for it to be useful you could always route a pipe for something, air intake, cooling, something..
