Wind GT (Stage 2+) | New Wheels

[MovingShadow]

Before everything started I asked Ktec by mail if they can fit it and they said it wasn't a problem so I wasn't questioning their capabilities.

when they refer to a kevlar clutch rob, it means that it has kevlar added into it. the higher the percentage of kevlar there is in the friction plate, the more torque it can handle. this 'stage 2' clutch will have a little bit of kevlar in it, with slightly thicker pressure plate forks and springs to handle the increased torque. it's no different from fitting a normal clutch, just appears they didn't remember that kevlar clutches and uprated clutches need a longer bedding in period. these sorts of things happen

matteo will be cutting around belgium in his 140 bhp wind very soon. i'll certainly be guessing that you'll be close to 140 that's for sure. we're close to summer to, it's almost time to bring the best out in the car

 

[MovingShadow]

I'm hoping it's more than 140. According to Ktec with the intercooler alone, their Twingo GT got to 140 bhp. So with the decat and sportscat I'm hoping 145 bhp (fingers crossed).

Okay, now I got some emails and it's getting weird..

this is a mail from Ktec:

The clutch is slipping with the same power as when you bought the car into us as we have not been able to map it due to the faulty injectors.

We would not normally expect a clutch to slip as part of the breaking in period as this will start to wear the clutch.

It may be worth speaking to the company that made it for you.

So I send a mail to Andrew from clutch-specialist and this is his respons:

They have never heard of a clutch that needs to do this!?!?! All clutches of every brand and manufacturer require a 300-500 mile bedding in period. This period of soft driving to allow the clutch bed in is essential and failure to do this can cause long term irreversible damage to the clutch.

:roll:

I'd be asking Andrew if they supplied any fitting instructions to cover yours and clutch-specialist's back as it looks like Ktec have tried mapping before running the clutch in :|

So, they know theres a breaking in period. Kevlar will take a bit longer than a standard clutch, so may slip untill its bedded down at least partly and, one trip would be unlikely to do that.

The mileage is kind of irelevant, its the number of engagements and amount of slip for each of them that will wear off the rough top surface and allow it to bed down.

Slipping isn't necesarilly bad, unless they keep it in a slip condition which will build up heat and cook the compound. its not much different to feathering the clutch for a hill start, which will be causing some slip untill its engaged fully... Its not like you keep the clutch feathered all the way up the hill

Okay so I just came off the phone with David from Ktec.

They're driving my car around town for bedding the clutch a little more, when that's improved they will put new injectors in and remap it.

 

[oscar]

nice one! they'll have no excuses not to send the new guy out for everyones mcdonalds lunch ''i cant sorry, got no petrol'' .... here's some keys ; now get a pen and paper lol, no just kidding man. it's good to see that you realise things like this can happen when it comes to cars, it just goes to show you that for any flaws ktec may have they sure as hell put it right without even hinting at any extra costs to their customers and take it on their chin.

what injectors were you going for again matteo was it R26 injectors?

 

[MovingShadow]

I suggested Megane RS injectorsas well but they said to go for Clio 182 injectors anyway.

gladly they did not use megane RS injectors else i cannot keep up with you anymore

 

[MovingShadow]

I asked for an update yesterday and saw this email in the morning.

The car has now been mapped and we hope to be test driving it tomorrow. The clutch is certainly feeling better so we are keen to see what it is like with the extra power and we hope to test this tomorrow for you.

any power numbers yet ?

I phoned them today and got Sean on the line.

He couldn't give me numbers yet and said that Friday it's going on the dyno and then they'll discuss the arrangement for bringing the car back.

 

[singlespeed]

Just pick it up at FCS

Just pick it up at FCS

If it takes any longer, I'll have to..

But the good thing is that I can meet them halfway (in France or something).

I had to go in a kinda emergency surgery last week and now I have to stay home for a month so I got time to meet them halfway and they don't need to drive all the way to Belgium.

So I received the graph from Ktec and I have to say the result is.. weird.

Since they didn't know what power it had before the remap, they used the graph from a Twingo GT with full exhaust and air filter (maybe JE_GT's ?). The lower lines are from the Twingo and the higher ones are mine.

So the outcome is 119.6bhp and 146.5 lbfs/ft of torque.

Strange outcome as my original remap was 127 & 190 Nm (140 lbfs/ft)

(my first remap graph)

So it has less horsepower but more torque? Is it possible that the horsepower is calculated differently between the 2 remaps? One at the flywheel and other one at the wheels?

Email from Ktec:

We have tested and mapped your car on the dyno and tested the car on the road.

On the dyno we only managed to get 119.6bhp and 146.5 lbfs/ft of torque. This is a little lower than we expected to see but due to the ecu issue we were not able to see the power figure before the parts were fitted and mapped.

The car is performing well and I have attached the graph for you to see. The lower lines on the graph are from a Twingo GT which had a full exhaust and air filter but was otherwise standard. You can see very good gains especially in the mid range from the parts which have been added to your car, its just the top end which does not quite hold onto the power as we expected. It may be the actuator is a little weak causing the slight drop off but otherwise the results seem good.

I emailed them back with my old remap graph to show what it was running before they mapped it.

Wheel power Vs engine power.

 

[MovingShadow]

Wheel power Vs engine power.

Now I notice that my first remap is shown the power at the engine and Ktec's is at the wheels..

Making a direct comparison is fairly pointless when your considering RR graphs as there's loads of variables to consider.

However, that said, its a bloody good difference everywhere and a nice smooth curve. Safe to say its going to be noticeable and very usable

I'm sure Neil means usable rather than unable...
