My i20N

[RME1987]

So here are a couple of bits I’ve just seen being sold on AliExpress:

The first is the wing that we all have - this seems to be a 1:1 copy so not much use to existing owners but probably of much more interest to N Line owners as originals are very hard to come by.

This second is three options of carbon fibre bonnet - one with a single central vent, one with dual rows of side vents and one with no vents (like the original).

Watch this space….

I hate carbon bonnets.... but those dual side vents are so good looking... i know painting carbon is a thing but i cant justify that cost.

Edit: Of course the carbon will blend well with your colour, my blue not so much

Slightly less exotic than carbon fibre body panels, I’ve bought a new battery. I’ve Done this more as a proactive solution than an absolute necessity. As some may remember, I have previously had the old battery go completely dead when I left the car for a month. Since then it’s been fine but the stop/start hasn’t worked for at least six months (perhaps longer) and whilst this doesn’t really bother me it is a symptom of the battery not being fully charged. Also, whilst the car has stop/start it doesn’t come with a stop/start battery! Presumably this omission is a cost cutting move from Hyundai.
The three battery options I settled on were 1/ Bosh S5 005, 2/ Yuasa YBX 9027 and Varta D52 (silver dynamic). All three are premium batteries with pretty much identical specifications and you will find good and bad reports on them all.
After huge deliberation, which left me with no clue as to which to buy, I rather randomly settled on the Yuasa and it has now been awaiting fitment for the last week…. If it ever stops raining it might just find its way into the car!

Soooo…. I do already have another battery option…. I’ve got a lithium iron battery from Deadweight Industries and this is massively lighter than a normal battery - ridiculously so. But there is a problem with this battery and that is me - I do too many short journeys and these lithium iron batteries really don’t like that. To protect themselves they sense if their charge is getting low and shut down the battery so that it can’t be fully discharged. The result is the battery shuts down without any warning and leaves you stranded. If I had a garage I could simply keep the car on a trickle charger and that would be fine - but I don’t have a garage. I do have a drive way, but it would be a massive pain to have a cable permanently going to the car and I don’t have an outside power socket (perhaps I should fit one). So, at present, my fancy lithium iron battery is just an ornament .

i have run this for a year or so now and my trips are 20min here and there. have had only issue with track days which i have now sorted but normal day to day driving is ok. even at times have left the car for a week with no issue.

Sorry, you’ve run which battery? Do you mean the Deadweight? I have run mine but after a few days it decided it was too low and locked me out. I’ve since had it on a charger and it seems fine but I’m nervous to put it back in .

 

[TypeN]

yes, the Deadweight battery. Had no issues for daily use. If you need contact Deadweight for any assistance, they were very good assisting me. what do you mean by locked out?

I mean the battery decided it’s charge was too low and shut itself off and this meant that the electronic door locks would not work and I had to use the emergency manual key to get into the car.
I did contact Deadweight and they were very responsive but ultimately there’s not much they can do if I’m not sufficiently charging the battery. However, I didn’t have a lithium iron battery charger at the time so perhaps the charge was a touch low when I fitted it and this was exacerbated by my short journeys.

 

[YNWaN]

I’ve been thinking about the Deadweight Industries battery and the issue I experienced with it. I think the problem, for me, was that the batteries protection circuit kicks in when the battery is still at a relatively high level of charge - relative, that is, to a ‘normal’ battery that does not have such self protection. However, I am keen to use it as it is very much lighter than a normal battery - it’s an easy one hand lift.

Anyway, I fitted the Yuasa yesterday and proceeded to follow the somewhat bizarre ‘learning’ process - since then it has rained solidly and I haven’t even tried to drive the car.

On a moderately more productive note I’ve created a new avatar for the forum:

Hi,
What is the bizarre learning process?
Just connect the new battery, close the car and let it sit for few hours? Or is there more to do?
Thx

 

[TypeN]

Battery options?

Wow, that certainly is a super posh battery - very expensive though!

You mean this?

“Hi,
as far as i know, you have to connect the new battery then switch ignition on for about 30 sec. (not start the engine), switch off, close all doors, lock the car and leave it alone for at least 4 hours, then the ECU resets the learned battery values and start new learning cycle”

Those are the instructions I followed. The reason I described them as bizarre is due to the stipulation of a four hour wait period. Anyway, it’s done now (It’s had more like a 48 hour wait). However, thinking about it, I didn’t do this with the Deadweight battery and perhaps that was part of the issue. I’ll give it another go when the weather improves a bit. I’ve also got one of those battery monitors that connects to your phone via an app and that works with lead acid and lithium iron batteries. I’ve been running that ever since the original battery went flat on me.

An update on the battery situation - well I’ve finally driven the car with its new Yuasa battery and yeah, it works - no great surprise there . The original stock battery I put on my charger and after a few hours (quite a few) it seems to have fully charged .

I’ve also bought a new bit for my car. This is the lower engine torque mount from Airtec and is quite a substantial thing. I’ve already replaced the bushes in the stock item with Powerflex Black but this is the whole mount and it’s a different design to the stock one. The change in design means an increase in vibration (which doesn’t bother me) but it also means much less torque twist and fore/aft movement. If I still don’t think the bushes are stiff enough I will either make my own or replace them with Delrin ones (a hard plastic) and that will remove any flex.

Yesterday my car went on a little trip and this report/review was done by Tom of Paragon Cars (my car isn’t for sale) - he seemed to like it . The little trip wasn’t for the sake of this review though, it was for a different event - more on that to come….

I just watched that and recognised your car immediately. I jumped on to link the video and it was already here. Love the car mate, you've done a great job. I just wish Courtenay had an agent here. Any chance of you making a road trip to the Nordschliefe? I'd love to see what BTG time yours would do on a track day.

 

[YNWaN]

Thanks bud

It’s possible I might make a trip to the ring but the weather will have to be a bit better.

 

[OldGit]

Nice video. Great to see your car being used. Obviously it does look amazing and seems to go rather well too
I must say, I was rather perturbed to see Tom driving so quickly on wet roads in a car he does not know well.
I would not be happy seeing him using dabs of opposite lock on the road if it was my car!
Do you feel that the opposite lock was necessary? Is he really losing the back end or was that more for show?
I never mess with the stability (anti-crash!) settings on my car because I would never presume I have the skills to save it if something went awry
Anyway, very well done to you for letting a stranger drive your car so quickly.
What are your thoughts on how he drove your pride and joy?

 

[YNWaN]

Well, you make some excellent points. I think he probably did have to do the opposite lock movements if he was driving with stability off and given the conditions. Personally, I never drive in this manner when the roads are wet/damp and I certainly wouldn’t turn the traction control off completely (if that’s what he did). Ultimately, what’s done is done and the car was undamaged and drives just like it did before all this so there’s no point in getting upset. I did build it to be a track car that you can also drive to the shops.

We did discuss his insurance before this drive and he is fully insured.

A couple of updates:

The new battery has been working fine and stop/start now works again. I probably drive in N mode about 80% of the time so the stop/start feature is a bit academic but I guess it’s nice to know it works…

Fuel starvation. This issue first became evident when my car was stage 2 tuned but is more evident (perhaps not more evident, but no less evident) now. If the car has less than a quarter of a tank of fuel and you do heavy cornering and/or braking you get momentary fuel starvation (stuttering) as the fuel sloshes around in the tank. I believe a small swirl pot is built into the plastic bit that holds the fuel pump but it’s probably the same as a stock i20 and either doesn’t hold enough or it just sloshes out during energetic driving. It’s fine for the i20 but not sufficient for the i20N. There are solutions for this but it’s a pain and is basically a separate header tank that is mounted in the engine bay and acts as a small reservoir of fuel to buffer any momentary surge. Of course you’ve got to find a place to mount it and also plumb it all in. The simple answer is to keep the fuel tank topped and not let it get to being three quarters empty, but that’s easier said than done with such a small tank as the i20N has!
