I had a spare bonnet given to me by a friend.
Drilled a few holes in it and stuck it on the wall of my garage.
As it was white, I was using it as a board for ideas/plans for alterations to the van.
Fancied something different and a friend of mine Carl, who runs D7R Fabrications, had been doing some very cool stuff with hacking/venting front arches on some of his customers cars, so I gave him the bonnet to see what he could come up with.
Adding a vent for cooling the bonnet temps and hopefulyl feeding some moving air to the TMIC
This is what he came up with:
Had to add bonnet pins, as the latch wouldn't fit and needed to be removed.
Honestly, I wasn't sold on it.
But as the work was done and Campermart was looming, I thought I'd have a go at getting it on the van.
Carl insisted it needed to be colour coded to look good. So off to the painter to see what could be done.
When it came back, in yellow... I STILL wasn't impressed with it. I just couldn't see the vision Carl had.
Even as I was adding the mesh to the thing, I just wasn't sure.
Then, once it was on.... I could see the light!!!!
VERY VERY happy with it.
would it not worked better to have the scoop raised and the opening on the front (high pressure) edge of the bonnet? At least with the slot where it is the low pressure should suck hot air out of the bay (up through the IC though...)
Aero catches are a winner.
Yeah it's all kind of an experiment.
I am not 100% sure if it will help or not... or possibly even make things worse
Right now, I just really love the look of it, so I will run it until I find any issues with it.
There is an EGT on the top of my downpipe, so I will be able to monitor temperatures.
Plus, I have a seperate AIT sensor too, so I will be able to see if the temps stay higher for longer. all shows on my PLX device on the dash.
Honestly, I only drag race once or twice a year, so It won't really have any massively negative effects.
Going to keep old bonnet on the wall, so if needs be I can always use it again.
Long term, as they are only £85 a go, I could always buy a NEW one and try a different design
