Dual Nostril

[Randy V]

Virtually none of the dual nostril hoods I've seen that come from the mfgrs of our "kits" - are as deep as the originals.

Here is the difference between the single and double as I have both:

I wasn't happy with the thought of the double nostril hood either coming off due to high pressure under it, nor the lack of cooling airflow that some have talked about.. So I decided to take action..

These pics are a brief look into what I had started to do before I stopped working on the GT40 almost a year ago.
Maybe this will give some of you some ideas as to how you'd like to approach a project like this.

Pretty much as it sits today with some minor filler added here and there.

Almost the entire project was done wit West Systems Epoxy resin and 3M high strength repair filler. Not much bondo at all.

No it is not 100% correct, but it will work and when it gets completed someday, I don't think it will look too hideous.

Pretty good exposure of radiator and fans now:

Also remember on the originals that had half depth twin nostrils has a metal kick up plate that went from under th radiator up the the nostril pannel

Hi Great Minds think alike, As my KVA's nostral panel was hacked up when I got it ( cut to clear frame members ) I had to fix it anyway So I dropped the floors and moved the front edge back ( this no longer has to be removed to open the front clip ) which gave more length for the radiator extension panel.

:thumbsup::thumbsup:

Nice work Wally.

very nice picture book Randy, looks way better for flow, what a huge difference, also more downforce this way,
also nice Wally, I don't understand why those nostrils did not came this way in the first place...

@Randy, is it also possible to make it even more forward/longer zo it sits almost or with some rubber against the radiator that way you would have max fit?

Thanks for the complement Randy. I love how you document what you are doing ( I just keep plugging along ) Nice work by the way. GTRene I think someone answered this as to make these panel like this they require being made in two pieces and bonded together. I on purpose moved the lower edge back so as to give myself more area to attach the radiator extension panel as the nostril panel seal against it when the front clip is lowered I wanted it securely attached. Don't know the interchangeability of these But the RF will get something like this done to it before it gets repainted. Hoping to find one to modify and keep the original as is.

Hi Rene,
I had planned on making a stationary piece or pieces that would mount to the radiator and then intersect with the hood. If I ever return to working on the GT again, that will still be my direction.
I have taken literally thousands of pictures of this journey and put many of them on my build site (link in my signature line below) - but I don't believe I put much on the website about the mods made to the hood. The website has been abandoned as well..

I wanted to also drop a note of thanks here to Mike Drew who helped me with some pictures to show me I was not crazy and basically on the right track.

My plans were to also use quarter turn Dzeus fasteners in all four corners. With the tilt front end modification I've engineered, the hood needs to be removed before the front end can be lifted. Of course the same would be true if I had stuck with the camcentric bobbin mounts as supplied with the car.

nice website Randy with lots of picture details.
is it only with the dual nostril type that you have to remove that hood first before you can open/lift the front?

also this dual nostril looks deep too

Hi Rene,

Thanks. One day I may catch up my website..
I don't think the single nostril hood can stay in place either when I tilt the front end forward. The dual nostril is now as deep as the single.

JimmyMacs stuff is always nice.
I like his hood panel better than mine, but that's the least of my concerns right now.

Hi Kevin
Some more ideas for ya, just pulled the mould out yesterday.
Started with Mk3 vent, but wanted the look of the Mk1, so spread the outlets apart (took 40mm from each side) then deepened them to the bottom of the radiator.
Its not the best for flow (large radius wall between outlets) but wanted the inner walls to be vertical and not tucked under.
