Hey guys,

Just received my carbon bonnet which has a scoop for the air intake

post-68489-13896052238974_thumb.jpg

And now need to make a POD box. It's simple enough to make a normal box such as the one found in this thread. http://www.skylinesaustralia.com/forums/topic/208224-making-a-professional-heatsheildpod-coverair-box-at-cost/

But I want to make one that has a seal around the bottom of the bonnet (top of box) where the scoop is to make sure the air is going where it should. I would think for this that I would need to form a compressive rubber seal the bonnet can sit on but unsure how to go about actually measuring the heights needed around the box walls to keep the seal on the bonnet??? I mean it's pretty hard to close the bonnet and see how high the walls and then rubber lining needs to be??

Any help would be greatly appreciated.

Basic idea:

Make the box in the general area of the scoop. Put some sort of thick/tall lining around top of box with some paint on it. Make sure itll touch the hood when u close it. Close hood, and you will get imprint on hood. Place Some foam on top of box and on hood where the paint outline was so that they press togethor when hood is closed.

Thanks I'll give the foam a go on top of the box then cut it so all edges are touching the hood with roughly the same force then I'll have the print for a rubber seal. Might use chalk so I can remove it from the hood and have several goes at getting the seal right on each edge.

I did a similar thing with mine.

I got the Perspex from bunnings (u can cut with a grinder or anything really) and the rubber edging from clark rubber which I glued onto the Perspex with sikaflex.

cut the Perspex to the required shape to make an airbox that basically seals against the bonnet (1-2cm of clearance) and then use the rubber edging to complete the seal.

Bottom line is you are never going to get a perfect seal so a good job will do 99% of the effect desired. The main intent is to block the air from the engine bay and make the easiest air for it to breathe from the cold air entry.

I made this setup for a 550kw Supra, force fed from the front bar by a 4 inch pipe. It used to lift the bonnet slightly at high speed so the seal must have been pretty good.

I used flat alloy sheet with heat proof foam backing, and the Clark rubber seal.

is this a full carbon fibre bonnet or a fibreglass with a layer of cf over it?

I have the same bonnet in fibreglass. but if I can find a full carbon fibre one I would like to upgrade, I have a arc airbox that sits perfectly under the scoop, been wanting to make a duct for it, post up photos of how you go with this

Attacked it this afternoon. Got the box done and the seal with a foam cut out. The foam still needs a bit of trimming to fit perfect and look a bit cleaner but I'm happy with how it's gone so far

yeah id say sand it to a smooth texture if possible n then spray.

even then, iv heard that the test most cops like to try is the grab n pull. if they do this n shit moves or breaks off they are likely to give the defect. You think it will stand up to that?

    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
