@Alias23: have you put in front or foresee to put a fine net / grid that shelters from possible stones or other material ?

Im not a fan of mesh if I'm honest, I just don't like the look of it, hence why I've gone this route vs say the WinAce items. That open aperture of the scoop just looks cool so im keen to not hide it with front facing mesh.

However, I do feel protection is required, mesh will be used at the rear of the scoop. 

On the intake side, I'm getting a round mesh frame made (example below), this will sit into the OEM intake elbow (red circle). The intake elbow is taken off the OEM scoops and re-attached to the carbon scoop as part of the install process.

As the mesh is on the inside of the intake elbow it makes it both compatible with folks running a standard OEM airbox as well as those running KT or alias23 intake. The mesh will not be visible but I'll likely get it anodised black to satisfy my OCD.

On the other side of the car the rear mesh if you look into the scoop is 'just' visible, so ill be looking to use anodised black mesh (example below) which will be bonded into place.

Thanks to those who've ordered. I'll be looking to complete final numbers over the weekend and ordering with the supplier Monday.

Ordered👍

Completely shitting myself  when it comes to fitment😬....... so a total-idiots guide installation instructions will be more than appreciated😉

[MAG]

Great stuff, I totally agree RE mesh 😁

[stephenwhyte]

@alias23 - any update on when these will be ordered and how many people are buying?👍

[alias23]

Hi Guys

Order placed with supplier. I’ll be sending an email update with a bit more information over the weekend

My bad filming, monotone voice, and appalling editing skills continue with a comparison against a 430 Cup!

Great video👍 @alias23 they do look good and happy knowing they’ll come with the mesh added.

very interesting product. congratulations.

Over the weekend I managed to get a little work done on test fitting the mesh discs on the intake side of the car. I tried two sizes to be safe and found the one size fitted perfectly inside the OEM intake elbow which is retained and connected to the back of the carbon scoops. The idea behind using a fabricated mesh disc is to keep the install simple and clean whilst also allowing the scoops to be used regardless of if using an aftermarket intake or OEM airbox. Have to say im very happy with the test fit.

The disc is pretty tight on fitment but will be further secured using a jubilee clip around the outside of the intake elbow.

Forgive the dirty car! This is the view when you get your head into the scoop and look up ... not that any normal person does this haha

The discs are fabricated from stainless steel so my original plan of anodising black is not going to work. Thanks @GFWilliams for the reminder... so im going to get them powder coated black. Really happy how the kit is coming on

Above and beyond Imran👌 - as someone who’s ordered and looking forward to seeing the new Alias23 scoops, thank you for all your efforts!👏🏻👏🏻👏🏻

@alias23, I remember on the Esprit that a 1mm wire in a 3mm mesh cut airflow by 40% according to Dermot, who knew his Esprit and was an Oxford Don. Have you measured the effect this has on the airflow? 

This is his very old and neglected webspace, he's a clever guy and being the Head of Inorganic Chemistry to used to make his own fuel for a better stoichiometric flame speed and all sorts. Very much the analyst.

An interesting point made @Bibs........

@alias23 what was on the original air intake part of the factory scoop? And do you know what was used on the 380/430 Cup models?

[vd9]

It is a fairly basic math that is needed to understand what opening with what flow speed is sufficient for the engine (displacement+compression+desired AFR+max RPMs will give you what the demand is; clear area of the most restrictive part of the intake+airflow speed will give you the supply; then you only need to make sure that supply is not less then demand at any point in time). I somehow think that airflow is not a restriction on the vast majority of the forced induction cars, and the only difference that fiddling with air intake makes is uncontrolled change of the AFR.

the 430 has mesh in the sidescoops - I know as I had to take out a bunch of leaves! 

If you want me to take a pic, roughly measure the mesh, let me know. 

[TBD]

I wouldn't even think twice as long as the remaining open area is larger than the throttle opening, which it certainly looks to be. Further the entire scoop is a forced air compression chamber, which is its entire purpose.

Folks ... I have an update ... will post later after work but @Bibs great point and definitely helped make an improvement to the kit as of this afternoon

[stephenwhyte]

What a great community this is - great to see people making comments to always create positive suggestions and solutions. Love it👍👍👌

On the 430 (22) it seems that the duct is a part of the side pod. whereas on 350/S, two distinct parts (6,18)

[alias23]

Guys I was ushered into hospital last night and just got home so a little whacked. All fine just need to recover when I’ll post a mini update on the mesh thinking after looking over a 430.

[stephenwhyte]

Hope you’re ok Imran👍

[Karls]

Hope everything is ok Imran.

[alias23]

Thanks everyone for your kind messages. Im gradually getting back into things albeit still a bit rough. Seems like a mix of dehydration, too much travel and work going on which just took a head and knocked me for six. I'll be back in full swing later in the week. Thanks again.

[NANO]

Imran ... I hope you feel better now ... give it strength ...

[alias23]

Okay guys well today was the first day that I felt like I was getting back to normal! So thank you all for your kind messages.

As promised a bit of an update albeit a few days later than expected! I concur with previous notes regarding the ability for forums to help drive feedback, ideas, and better outcomes and I think in this instance it definitely has improved on the design. Thank You!

With the help of a 430 Cup owner I managed to get my head into the scoop of a 430 again and look at what Lotus do out of the box on the intake side of the scoop.



The OEM setup still retains the intake elbow as a separate item so it is not one piece with the scoop as Deroure may give the impression of by their illustration. The mesh itself is wider than the mesh I had originally planned and it appears to be 'wedged' in but without any edge.

I still feel strongly that an edging makes a more secure fit and better design, but I will be changing to a wider gapped mesh, going from 5mm to just over 11mm, this should also be closer to OEM. Being stainless and powder coated I hope to avoid rust which OEM seems to develop over time.

Speaking with the supplier via email on Friday I have a target ship date to me of 29th November - So fingers crossed
