Hi All

anyone done this mod and can comment any issues please? KT website suggests 20bhp potentially on offer but caveats it with “recommends software tune”

thanks

They will not sell it to you without a complete tuning kit (they want to make money). I know an employee from the 2nd biggest official Lotus dealership in Switzerland who is using this on his Lotus Exige 380 without any issues at all (took it out of a customer car they've bought and installed it in his car, without a software tune, and he's a mechanic himself).

Some more googling has found this product. 
 

https://www.vone-racing.fr/produit/boite-a-air-carbone-exige-3-eleven-evora-v6/

 

anyone have any experience of it. I’ve used a translator and don’t think it requires a remap (emailed them to confirm)

 

Why not the Alias23 intake...?🙄

Not available for 4XX cars as far as I’m aware 

Nothing stopping you putting it on 4xx cars, my understanding though was that all development was done on the non charge coolled Exige V6S cars so the results may be unpredictable.

Also, the ECU code was changed I believe for the 4xx cars meaning a MIL light could be thrown.

And finally, I am not aware that they are still in production.

Did they get back to you? I'm thinking of ordering one of these for my Evora 400.

They didn’t but in the description underneath if you translate to English they state this 

The “raw” performances without a map compared to the standard air box are obvious with +33 hp and +42 N.m! (See curves)
We remind you that it is strongly recommended to have the mapping of your Lotus adapted after installation of this type of part.

After Carto + Air box we are familiar with the 500hp on a Require 410/430 base…

If you have an evora 400  get the Greg’s race parts one. I had one on my evora 400 for 3 years with no issues whatsoever. An even better mod is the Komotec 435 map which transforms the car  

 

that being said, Vone Racing one looks very similar. I’m not an expert but as long as internal diameter of where the sensor goes is same as stock then there “shouldn’t” be an issue  

Keep us posted with what you decide 

the first year I installed the Komo-tec intake and went to the dyno, you gain 15-18 hp without reprogramming. The ecu takes care of itself.

the intake noise is nice

@RedViper Hi, I also concluded that the Vone Racing carbon air box was the best option for my 430 Cup (I already have a full 2bular system and EPK), so the next step was ordering the air box and then Back on Track were going to arrange a new ECU and rolling road tune for me to optimise the set up.

Unfortunately, you can’t select the UK on their online shop, and they have been non responsive to email contact asking for guidance on whether they accommodate international orders.

I will try speaking with them directly, but my French speaking skills haven’t advanced further than Tricolore textbook levels from the 80s.

 

If you already have the full EPK I’d go down the KT route. It’s tried and tested and all you need is their airbox and map and won’t need standalone ecu. 
 

the only reason I was looking at vone is because I’m unsure if il go whole hog to a KT475 and just wanted an airbox. KT advise against installing just the airbox without a map and once you use a translator is seems vone racing are saying same thing.

@Cochi Loco - I know several members on here regularly go "touring" in Europe and drive through France etc. It may be possible to see if anyone has a trip planned near to where Vone are and could pick this up for you after you had paid for it. You might even be able to avoid the customs tax?????

@RedViper iirc KT will only sell you the "full kit", so you would need to take their headers/exhaust etc for the 475 kit, which makes no sense if you already have the EPK. Last I heard KT would not "unbundle" their performance kits as they stated that everything has been optimised to work together, which makes sense, as they do provide a warranty etc I believe.

Ahh ok. I was a little unsure on they when I wrote it. I know years ago people were running EPK with 430 kits but that’s prob 10 years ago. If I remember correctly you got more torque but less power or vice versa when comparing against KT offering. Will be on this forum somewhere I believe. 

Thanks @C8RKH and @RedViper. Good idea re asking a friend to collect on way back from Switzerland or France - I have a couple of options.

I ordered a Jubu upgraded charge cooler surge tank from Austria a couple of weeks back and it’s stuck awaiting customs clearance..painful!

And yes, agreed, the KT 475 kit is a full package which doesn’t make sense if I already have a full 2bular system (and KT don’t like to sell the air box/tune separately).

It’s unfortunate that KT do this,

The EX475 tune and Airbox are both good, however there are better options for headers, ypipe and  200 cel cat. 
 

 

If you need help in France send me a message 

Just wanted to update this thread now that I have completed the upgrades. So Komotec now sell their carbon airbox as a standalone item given repeated requests so that’s what I went for in the end.

Back On Track fitted the KT airbox, AIM digital dash and new SCS Delta ECU. The car was then transported to SCS in Norwich to get set up on their dyno and road tested (marginally more power at ~450bhp).

The car was delivered back to me this weekend and I have done about 50 road test miles since its return. It feels and sounds v different - more urgent, more torquey, definitely quicker but will need track time to fully assess.

I’m off to the Nurburgring for a track day at the end of the month so that will be a good opportunity to test it out properly.

SCS also added auto-blip to the ECU function which is activated in Sport and Race mode at higher revs/speed. I can heel & toe easily in my S240 Exige and my 993, but have always struggled to consistently HnT in the 430 Cup so I’ll see whether I like it. I tried HnT manually post the new ECU and it was much easier.

NB: only other existing mechanical mods are a full 2bular exhaust (manifolds, EPK, sports cats, QP track back box).

Hopefully all goes well on the trip to Germany 🤞

Thanks to your post I'm now 1300 Euros poorer (as I've now ordered the carbon airbox from Komotec). 🤕

But richer in so many other ways :D

Haha, sorry! It sounds fantastic though! 😀

I'm sure it does! They will even send me a new tune (currently have their EX435 with a K&N filter insert) to adapt to the airbox change... for only 500 Euros more! 🤑🤬🤣

Thanks for the update. What torque figure did you achieve please. Or even better do you have a dyno graph 😃. I have pretty much decided to go the SCS ecu route myself now. Just waiting for warranty to expire in June on my 420. Interestingly you are 3rd person I’ve heard do the SCS route in last couple of months and everyone has got around 450bhp. However the other two are running stock Cats and one even stock airbox. Do you know if SCS work to a certain constraints for safety as I would have expected uprated manifolds on yours to give a chunk more power.

great news that KT now sell their airbox as standalone item Too. I’d decided on Vone racing but as other found got no response to emails or sounds like wouldn’t be simple mail Order option.

That’s a new development. Do they offer any updated performance figures for that option please. Does it feel any quicker with tweaked 435 map and the induction? Thanks

@RedViper The torque figure was 389lb ft. I agree with you, I thought maybe the car would get more power given the manifold/cats, but I was assured that SCS tune to get safe power and to increase torque.

Once I’ve had some decent time in the car and find time to go back to BoT for them to have a test drive with it and give me more details re parameters, I’ll reserve full judgement. So far though, it felt very strong.

That’s great to hear. I’m definitely going to go down this route myself. Thanks

I have an Exige 410. With their EX435 tune and the K&N filter insert, the car feels more alive and quicker above 5000rpm. However, this is not a drastic difference... 20HP more in relation to 416HP stock, is a small increase. It simply feels like the car is a bit less restricted from 5000rpm onwards, with a little bit more of a kick towards the end of the rev range.

I've asked Komotec if there will be a slight power increase again with the carbon airbox and the adjusted tune. To which they've replied: "Yes, there will be slightly more power again, but you should take the car on a dyno after installing the intake and loading the tune file."... I've asked them why I should take the car and test it on a dyno, if it's to measure if there's an increase in power (and how I'm not keen on spending even more money for a dyno run here in Switzerland). No answer anymore since then... from my experience with them so far, Komotec is really not good in terms of communication skills (maybe they are better when you visit them in house).

I'm not sure if I will take the car to a dyno. Everything is expensive in Switzerland, especially hourly rates. I've bought the airbox mainly for the sound, and if the power is the same as it is now, I'm fine with that.

Would I recommend the route I've taken so far? Definitely not. It has cost me a lot when everything is added up:

• Initial EX435 tune (including My Genuis device to upload their tuning file) plus customs fee: 1500 Euro

• K&N filter insert (they sent this one for free together with an updated EX435 tuning file, because the first version didn't increase power at all) plus parts installation at my dealer: 100 Euro

• Airbox (1300 Euro) with adjusted software tune (500 Euro), including customs fee and parts installation at my dealer: 2200 Euro

• Another 200-500 Euro if I want to pay for a dyno test here in Switzerland

This brings me to a total of roughly 3800-4300 Euro, for basically a Komotec EX435 tune plus carbon air intake box. Very close to the price of their EX475 kit. 🤐
