^yea have spent ages googling tbh and have seen them.  Got a couple of mates coming around in a few minutes to help me swap the bonnets over.  Then I can start to get a better idea what height I have to play with but also where the cut outs would sit.  I agree the VR/S has such smooth lines I don’t want to stuff them up.

Hard to see coz I did it in pencil, but you can see one idea I sketched is similar to above.

So you are not going to cut out out directly above and seal it with foam like an . Im trying to visualise what you are doing.

 

 

So  not like this

 

 

 

 

Only front feed?

That’s alright, I am trying to work out what the hell I am doing too!!

This is rough as guts, but its the sort of idea I am kinda working on.  The second bonnet is fairly rough condition, but that’s OK as the plan is to cut and modify it to try and see how I want it, then once I am happy, neatly transfer it to the current bonnet.  But yes only front feed, although will most likely incorporate a vent near the rear to reduce general under bonnet temps.  Maybe even a rear grill/vent of a first gen Commy.

Not sure you can work out what i m thinking, so basically two scoops into two bulges.  They are boxed in under the bonnet and sit down on top of the air boxes when the bonnet is closed.

[sands vsParticipant vs commodore View build HERE Member since: March 1, 2015 Posts: 619]

Ah yes now it makes sense great images in my eyes.. Hardest bit will be trying to make it look decent I suppose. Will you retain the bonnet liner just cut it?

Great thinking should keep the temps into the intake down. If it works well enough might even be able to touch up the tune and get more out of it.  Does it get very hot in the bay now?

Yea my plan is to refit the insulator.  It gets mental hot under there now.  That’s the main reason for doing it.  Not so worried about figure it makes on the dining more that it’s nice and usable.  Hopefully it will look good.  Bonnets are very much personal taste though.  If its neat and actually functional that’s the main thing to me.

Without decent heated enclosure large ABS is really a challenge to control warping

The route I’ve taken in the past for these kinds of thing is to print an inner or outer mould and use either fiberglass or carbon for the finished product.

Print out an mould in PLA, sand, prime, fill to desired finish. Seal and spray with mould release and lay up your fiber of choice. You can use the print itself or make a more traditional negative with fiberglass then use that as the mould for the carbon.

Another option could be to print the negative in ABS and just cover the outside directly with carbon. Heat resistance + strength + less concerns about ABS surface finish.

I’m sure if you persevere a solution  with straight ABS will prevent itself. The more i print the more i realize these thing are absolutely fantastic for prototypes but fall a little short for production in some cases.

^cheers mate, actually just bought an old school large TV cabinet, going to get some acrylic doors for it and have myself a  nice budget enclosure.  I seem to have got the warpage pretty well sorted by bumping up the temps, and keeping the door shut to the print room..

So have had a bit of a play around today.  A little hesitant to post this up as I know everyone’s idea of bonnets is different.  I really like the simplicity and functionality of this, which sorta goes with the look I personally like.  The steel one will have a nice say 5 or 10mm rounded edge around, and I am thinking of a simple grill mounted inside a few mm back form the edge.  Unfortunately have a crook ankle right now so that prob about it for today.  But will leave them on, crack a coldie and give it some more thought.  Then time to get out the grinder and start mocking up how it works with the air boxes.  Few phone pics for posterity.

You really need to think this through carefully

Not a fan at all Gary.

This would look better or even a really low line HDT reverse cowl type with the opening at the bacK

I agree with the others Gary. Not a fan looks out of place. Although it’s been done a million times, a Monaro bonnet or a modded reverse cowl would suit better.

I’ve never been a fan of the twin nostril type bonnet scoops.  As above, a small reverse scoop or HDT VL style scoop would be the go.  Something like this…

[cava454Moderator 93 VR BT1 View build HERE Member since: February 20, 2015 Posts: 2 390]

That’s the one mate. I think this is he best option IMO then you can seal the intakes to the bottom of the cowl and happy days. Same theory as my air tray

Yea, wont lie, rethinking this.  Starting to think about an option that doesnt come through the bonnet.  Maybe an otr where the bonnet forms the top half.  Needs more thought.

Trouble is the lines of a VR are so clean.

[cava454Moderator 93 VR BT1 View build HERE Member since: February 20, 2015 Posts: 2 390]

Unless you slant the radiator back and allow it to get some cool air an OTR will heat soak like a mofo.

Try get someone to photo shop one of those HDT scoops on. If it looks good then you could do something really cool with it.
