Here's some pics of my car with bonnet vents. There XA GT falcon vents, I think they look cool and between fitting them and fitting the RPW thembolic spacer its made throttle response a tad better when the engine is at operating temp. Comments would be appreciated positive or negative dont matter to me.

It might be just me, but I can't see any pics in your post ?

Love em. Well done

Love em. Well done

thanks mate. It took about 4 hrs to fit em with lots of double checking of measurements so as not to stuff a perfectly good bonnet.:happy:

Here is my opinion...

You haven't colour matched the vents...



Have a look at the genuine TMR380 bonnet...here....http://www.aussiemagna.com/forums/showthread.php?t=62854#post1296892

Oh yeh I just noticed, by the way it aint a TMR

Oh yeh I just noticed, by the way it aint a TMR


Yeah, I've got a pretty good idea of what a TMR380 looks like, (BTW genuine TMR380's don't have the bonnet scoops), only the concept car did.

White fitted the bonnet from the concept car which he got from TMR as a spare part.



You need to paint your scoops.....:)



EDIT....you will need to fill the screw holes now as well.

Yea just colour code them and it'll looks sweet. good stuff anyhow

personally i think you've lined them up wrong, rather than matching them with the creases in the bonnet i think you should have lined the rearmost (closest to the driver part) up so it was parallel to thecurve on the top f the bonnet. ive had three looks at the photos now and think the same thing each time.
props to you for doing something different though!

I bet those cool the firewall really well.

Seriously though, there is no way that would have improved throttle response.

My opinion.

It looks good.

You've kept the gunmetal versus gold theme which is fine. It's not a TMR, you're doing your own thing.

The only thing for me which jars slightly is the screw holes. If the 380 had other areas where there were exposed screws it would be OK, but it sticks out.

Looks good, just paint em.

looking good mate, they look good the way they are

Not a fan sorry

Like others said maybe colour coding would look better

Point taken about the colour coding thing but I like the gunmetal theme and the bolt on look is a sort of a race look even if the 380 has no real race pedigree so to speak, it may have done OK if given the chance in the right situation. But thanks for the feedback I'm just trying to do something a bit different, and you would be amazed about how much cooler the plenum is with this mod. I'm not saying it's better throttle response really, just stays the same as it dose when the engine first reaches operating tem just to clarify that. We all know they go slightly better at that point, Yeh?

I like it.

Not my cuppa tea for my 380 (Im an old mofo these days...), but looks sweet and is kinda original.

Looks good, much better than without...I don't believe its much of a performance mod, but at least it will be noticed and have the ability to vent out hot air on hot days

Pretty sweet dude, color code them though properly in 2K none of this acrylic shit and yeah, nice :)

It's the only 380 with bonnet vents at AMC so well done for having an effort.

I was quoted a thousand bucks for a similar fit and bonnet respray....

It is quite likely that throttle response may be better since fitting the RPW thembolic spacer, haven't heard of anyone doing it on a 380 yet, so good to know.

So... what the hell is a thembolic spacer?

Also are vents proven to improve the performance?

good to see someone else has done these. i prefer them colour coded. the only difference i noticed when i opened my vents up was the rear bank of extractors were cooler while driving. used a thermomater to check engine bay temps.

ive still got a bonnet with one vent done just gotta do the other one.

as for thermo block did jack on my motor. may work on a stockish motor though. i fitted mine after i did headwork and cams etc.

Do you have any issue with water draining into them when its raining?

mine just dripped behind the motor not actually onto it.

Without even reading the follower posts. I thought the same thing. Colour Code them.

P.s. After reading the follower posts, agree with the alignment to the bonnet edge thing (shouldn't be too hard to change surely?)

P.p.s. Looks good!

The thermo block is a subtle thing but noticeable for me. Soon I will get a piggyback ECU this I hope complements the mods I have already done which are CAI , extractors and full exhaust system with high flow cat , tranny cooler and slotted discs. That will do it for me cause I,m running out of excuses to give the wife why it needs all this shit.

Colour coded....

you are a GT owner, not an oldie LOL

I like them as is

Yea, definately get them colour coded. Should of used some sikaflex to glue the vents to the bonnet instead of screws. Thumbs up for thinking outside the square though :happy:

YES, BUT, in the case of removal....self tappers are way easier then removing sikaflex from the bonnet everytime!

A thembolic spacer is the key part in a flux capacitor... both are needed for time travel

Bigger intake manifold spacer. Supposed to lessen heat transfer to the intake manifold despite the fact the bolts holding the intake manifold down are metal and still transfer heat :)

I didnt notice anything when I put mine on...I didnt check to see temp figures tho.

When I fitted the spacer to the manifold I noticed that it's only the heads of the manifold bolts that are transferring the heat to the manifold as there is a clearance hole for the bolts , so I went to the local fastener shop and purchased 10 or so vulcanised fibre washers to insulate the bolt heads from the manifold and also the support brackets at the back. This I think has totally insulated the manifold from the rest of the engine, having done this you need to reconnect the earth from the manifold to another part of the engine so as its still earthed properly and all's cool. My inlet manifold stays cool , just luke warm really this has to have an effect on the temp of the air charge going in. The RPW product is good but needs these extras to be properly effective.(Y)

I like the vents the way they are, nice one.

With regards to intake temps, i cant see the spacer having much of an effect on intake temps at high speed, the air would be passing through the inlet so quick i doubt it would have sufficient time to warm up. A more worth-while manifold mod would be to polish and smooth down the insides of the manifold itself. The casting from factory is quite grainy and a lot of crap sticks to it. Just my 2c

Probably a stupid question really, but why does the inlet manifold need to be earthed out? Would it matter if it was isolated from the rest of the car?

Throttle body wiring may require a ground?

they look heaps good, how hard were they to do?

I fitted the RPW 'thermoblok' inlet manifold gasket a couple of weeks ago, and took stratman's advice and also fitted fibre washers.

I haven't noticed any reduction in manifold temps at all. Not measured as such, just going by touch & feel. Still far too hot to touch for any longer than a split second.

I suspect it's mainly down to the heat being given off by my unshielded and uncoated extractors, especially the rear extractor.

So unless I pull my extractors off and get them coated, or get a new coated set fitted (mucho $ either way), I reckon I could benefit from bonnet vents.

.......I reckon I could benefit from bonnet vents.



I'm thinking of the Evo one like in my avatar for exactly the same reason as you, the extractors make a ton of heat when idling.

Hey kj380 & Blackstar. I reckon you guys would be pretty happy with bonnet vents no matter what style you use, that must be the reason my manifold is so cool. I couldn't tell cause I did them both at pretty much the same time , mind you I haven't had a hot Qld day to see what it's like in that situation. Yeah and Blackstar I reckon if you did a nearly exact replica of you're avatars bonnet you're car would look sick. It should really keep cool as well.

Nice vents man, I kinda like the two tone!

PS, Blackstar - I was the original chopper of your avatar!

i can't remeber where I found it? On a forum in asia somewhere...could not understand the posts...LOL

could you email me a bigger pic of it?

need to take to a panel beater for a quote.....

I just looked for it. I studpidly hosted it on imageshack and the link has now expired. If anyone has a proper picture for it, please can you send it to me and Blackstar!

Someone on this forum, cant remember who, has a large image of it displayed in their profile. Will look now.

Minor thread mine.

Still seriously thinking about bonnet vents like Stratman's (you still out there Stratman?).

Anyone have any idea on the cost of a pair of these XA GT Falcon vents?

And how easy or hard they are to fit? (again looking at you Stratman)

I sprayed my extractors with 3M Heat Proof 650 degrees C 'ceramic' paint (aluminium colour) a couple of weeks ago. $20 or thereabouts from SCA.

Partly to see if it reduced the heat given off by the extractors, partly to cover up the spots where the blue coating had flaked away, cover the rust spots and improve the appearance.

Didn't remove the extractors, so a pretty piss poor coat on the rear extractor which is hard to get at but a good coat on the front extractor, both from the top and underneath.

Much improved appearance, but the jury's still out on the heat verdict.

So still thinking of ways to cool the underbonnet temp, like these vents.

Any help much appreciated.

KJ.

haha should have done it properly the first time and got them professionally ceramic coated before you put them in... like me!!! dont put bonnet vent on or you'll have all us young hoons trying to race you each set of lights :P

'sif that doesn't happen now.

Well done Stratman. I used to have an XA V8 and I longed for the scoops on it. I have loved them ever since. Colour coding or not, screws or not all comes down to personal taste and what look you are after. I have wondered about running one in as a CAI to the airbox. Obviously there are issues with rain etc but mmm I do like that idea. Also being just one vent and asymmetric it would ask a lot of questions about what is under the bonnet.

Thanks 380matey, well kj380 the xa GT bonnet vents are something I picked up from Ebay I looked for ages and then one day they came up. Yes there real fomoco and I imagine there would be some very pissed xa gt owners, but at $50 I couldnt pass them by. You can get repo ones at certain ford rare spare type shops around $80-$90. This one may be a good place to start your search www.fordmuscleparts.com.au there's a few more but I can't remember the names just do the google thing. They're not hard to fit if you're a bit handy and a little patient just double check all you're measurements and you'll do fine. Good Luck.(Y)

Thanks mate.

I did all sorts of Google and eBay searches last night and couldn't find any XA GT vents anywhere.
Just have to keep looking like you did.

KJ.

It's funny when I looked on Ebay I typed 'xa gt bonnet vents' and zilch, but when I trolled through just 'bonnet vents' I came across them. There's some cool looking v35 nissan carbon fibre bonnet vents on Ebay but you better have deep pockets.
