Sorry about the pic, the only one i could find.
Also what kind of monies im looking at.
And finally are they any good? Dave at TVMOT said that i need some sort of vent with my setup, just going to run bonnet spacers for the time being. The car has a propper front mount and a big(ish) single tub
cheers :D
Those FEED bonnets don\'t appear to have the vents in the best place - rear of the bonnet is a high pressure zone.
Bonnet raisers will probably actually make your underbonnet temps worse.
You need a decent undertray, and some decent ducting :) What IC and ducting setup are you running?
ah your the guy that helped me out with wheels on fduk right? Awesome!
Currently running no ducting that i know of, i presume you mean pipes taking air around the engine bay? Intercooler is pressed right up to the front bumper

The main reason for the feed bonnet was to keep it stock looking, not usually a fan of bonnet vents.
Also surely bonnet risers will work? Theres a flood of hot air around there, or are you trying to said cold air out side will be at such a pressure that it wont let the hot air out? If that makes sense?
cheers for the help dude :D
There\'s a reason why the air intake for cabin air is in the scuttle, dude, that\'s where the air pressure is highest when moving, so air is forced in there. Very hard for the vents to release hot engine bay air out at the point of highest pressure
so are we saying no to the feed bonnet then?
Though before i dismiss it, it\'d be nice to know what kind of temps people are getting running it.
Who has one then? :D
isnt that sweety wells old car?? why do you NEED vents?? people run huge power cars and dont run vents... look at wildays car he dont have vents... and he doing 10 sec 1/4 miles lol...
yea its chris\'s old car. I was told the car needs vents by someone who has seen and knows alot more about these cars than myself. Im really not a fan of vents, apart from the feed one, purely because it\'s subtle. As for the comment on wildays car, i would assume he has a different method of cooling, the car also has a different purpose.
I\'ve had one of these on my fd and they DO work quite well,I cant remember what my temps were but they did reduce after fitting the bonnet from a standard bonnet.
I have one and they work great, you can even see all the hot air comming out the vents.
ah good times. If you dont mind me asking, what kinda price did you guys pay for them?
think mine was about £500 new from shineauto in the us.

Same here.

Plus why would Feed run it on their Touge car etc if they did nothing at all?
I still want one of these bonnets too :)

Is that a rhetorical question? If not, I\'d suggest it might cynically have something to do with the facts they
a) want to charge millions of Yen to punters to buy replicas of their bonnets
b) want to have a style unique to their company so people can identify it instantly and people who are suckered into a "label lifestyle" will want to be associated with the name
c) all the "good" designs with the vents in the correct place to actually work well had already been snaffled by their competitors (e.g MazdaSpeed, who can actually prove stuff in a wind tunnel instead of errrrm, guessing lol:D) so all they were left with is the one in the OP
They do work and this arguement has taken place befor!
Iirc they work by the air moving quicker over the outside of the bonnet, pulling the hot air out from under the bonnet through the vents, simples.
Nik did you get out of the wrong side of the bed ?:2Confused
No he\'s just getting old :). I see his point, though, it is more form over function compared to other vented bonnets- Try the R-magic vented bonnet, ain\'t no way FEED\'s will cool as effectively as that!
hee hee hee. Getting old :Giggle! I\'m already old! :(
I just sometimes think that we need to keep an eye on the fact that these tuning houses are basically businesses, and they want your money. It\'s easy to get suckered into thinking that anything that comes out of Japan is of unparalleled quality and design, and this just simply isn\'t the case. Some of it is, in fact, just tat designed to separate the gullible from large amounts of hard-earned. I\'m sure FEED are an honest company and have an performance-based acme that they strive for, but I don\'t think even they can afford to pursue that goal in an economic vaccuum, and compromises have to intrude. I expect their vented bonnet does work, I just expect it doesn\'t work very well compared to one that\'s been, shall we say...better designed. To adulterate a well-worn cliche, we can\'t change the laws of physics, but we can persuade people that they\'ve been bent a little for the sake of a styling excercise

cheers dude, looks like it\'ll be a while before funds come in though, argh
I have the CF Feed but have always liked the AD9 bonnet. Which of the two would you say is the best design.
I am more than happy with my bonnet but i must say in traffic it could vent better, but on the move it works very well.
i have the ad9 on my track car:Thumbs-up cant really tell you how well it works compared to the feed but it does let a lot of heat out,mind you it would let a lot of rain in on a wet day to!something else that need\'s considering for a road car:Thumbs-up
Youd be surprised how well the feed bonnet cools actually. I have had both bonnets (feed and AD9) on my car with identical setups and I had cooler water and charge temps with the feed bonnet.

lol i remember meeting you in swindon and you having plastic sheet under you\'re bonnet and seeing how much water it had collected!
i have the feed bonnet on my car and it seems to work very well. its the only vented bonnet ive had on my car and i bought it for the same reasons your thinking of (bthebuk).
slight bit of venting whilst keeping the stock look.
I have the AD9 on mine and the Misses has the FEED one on hers, both seem to work well, if we take them out for a spin tonight I will have a butchers.
I had that bonnet on my fd before it got resprayed, although im not sure if was a genuine FEED, it was fibreglass though. When it was getting prepped for spraying we noticed it was bubbled up in places because of the heat from under the bonnet - looked terrible and really noticeable side on; couldn\'t have been releasing the hot air very well then!
I ended up getting the standard aluminium bonnet and got some vents cut into it!
