Puma Bonnet

Any experience with these?

Puma Bonnets for Land Rover Defender

The scoop option looks good and seems in the approximate suitable position. (according to the collective wisdom on another thread/s)
Interested in others thoughts. I haven't found a 2nd Hand Puma bonnet to compare.

I suppose if you had to replace the bonnet, a lighter, cheaper grp would be tempting.

Bonnet scoop looks great but you want air to enter the engine bay through the radiator. For highway engine temps, that scoop might be detrimental.

I guess that whether something looks good is a matter of taste, but that bonnet scoop thing on a Puma-engined Defender would only increase airflow over the rocker cover. As mentioned above, airflow through the radiator would be more useful.

As noted, increasing the air pressure in the engine compartment is not likely to improve cooling, rather the reverse. Do Puma's suffer from overheating?

It would probably also divert part of the airflow over the bonnet down, resulting in a more direct airflow straight onto the windscreen and an overall increase in drag - but the effect would be pretty small. Despite this, the vehicle shape is pretty high drag anyway, so you really don't want to increase it even by a small amount.

I agree.

No one has been game to do it, but if you're trying to pull more air through the radiator it needs to vent up through where they have that forward facing scoop, ie. that needs to be an exit.

Think of a Lancer Evo and the way the IC and rad are vented through the bonnet when rallying/racing.

Uninformed's guard vent worked really well in his 110 too.

I should have elaborated a bit more on the original post.
I was most interested in the quality/integrity of the Masai offerings. Im not having any issues with heat, though did think the vented bonnet was a tidy looking unit.
Im looking at these as I want to fit the acoustic cover on the TD5 and cannot with current bonnet I have (300tdi). The reinforcing gets in the way. The reinforcing on TD5 bonnet is different underneath. I discovered a TD% dfender with the acoustic cover on makes a noticeable difference in the cab despite my under bonnet insulation.
So if im going to get another bonnet and paint it id like to get the Puma style bonnet rather than a TD5 unit.

Looking at info about the net, my prefered option would be a second hand replacement TD5 or Puma bonnet.

I like to stand on my bonnet so flat TD5 preferred, and put off by this warning for grp

WARNING: As this bonnet is made of much lighter GRP (Fibreglass), it is not as strong as the steel Land Rover bonnets. Therefore we advise that during use, please be careful when you shut the bonnet and do not slam it shut.

Also the masai grp needs to be drilled for mounts and will need more prep work than a genuine replacement which will just swap straight on.

If you like the scoop they sell it separately for td5 bonnet. You could plonk it on for looks without actually cutting air into the e.bay. Black out the scoop interior so it looks void and use it to shelve a pair of flip flops!

...or just keep it original! Sorry, but apart from serving no purpose at all, those bonnet scoops just look naff.

I have a TD5 bonnet....it’s marked on the front and has a heap of addition rivets from previous owner.....

Oh and it painted G4 orange

And.....from memory your miles away
