This +1. I did some quick googling so sorry if my numbers are not super accurate but hopefully they give an idea. The average car alternator outputs around 500 - 800 watts. A UK 13 amp plug socket can output 3000 watts and you said takes 5hours to charge the battery. If your car can charge the battery in 90mins then its roughly putting out 3 times as much power as the plug socket so around 9000 watts so more than 10 times the power of a top end alternator. Same thing with a generator ... a generator with a higher output will require more energy to turn the input shaft. Energy cannot be created it can only be transferred from form to another. A generator takes in mechanical energy (kinetic) and turns it into electrical energy. So if more electrical energy is flowing out then you must have put more mechanical energy in the first place, otherwise you have magically created energy and solved the energy / cost of living crisis! That extra mechanical energy going into the generator in turn must have come from somewhere too ... it must have come from the engine; which has to work harder by putting in more air and fuel and creating a bigger bang in the cylinders and creating more torque. In some racing cars, folks often remove the alternator as it will be sapping up some power from the engine. They rely purely on the battery to provide enough power for the spark plugs for 1 race and then charge or replace battery for the next race. or they install the smallest alternator possible to reduce the drag on the engine.

@LotusLeftLotusRight, When the battery is being charged by the engine the energy being put into the battery has to come from somewhere and that must be from the engine. So your car will be using up more fuel when in charging mode as the engine has to power the wheels and the generator. Whether its better to keep on full hybrid mode the whole journey or switch back an forth to electric only when in town etc ... thats a very tricky question and depends on so many factors and how the car is setup. It could turn out the engine and gearing is tuned to be efficient when on the motorway and charging battery. So by turning off battery charging and reducing load you are not gaining much and it's better to have the electric mode for around town. Or could be better to just keep in hybrid all the time and let the car figure it out or could be better to just use up the battery and then stay on pure ice with no battery charging and only charge via a plug socket ... very hard to tell due to all the different variables. Best thing would be to try an option for a few days log the result and then try a different combination and see if there is a difference and which one works better for you.

Not had time to watch these yet. Anyone give a quick summary is it good stuff? 🤞🏾

Are these shifters better than the 4XX shifter or only an improvement on the S1 shifter? I’m very happy with the 4XX shifter’s performance on my S1 NA Evora.

I use my head to hold it up, it's so light weight you barely notice! 😄 Serious reply: The boys at ES put in a little rod with a hinge, similar to a rod to keep a normal car's bonnet up. The rods sits horizontal along the edge of the cut out for the engine when boot is closed and then hinges up and vertical and the end locates into a hole in the engine cover to keep it stable . Not sure if that came as part of the package or they rigged up something?

Just caught up on the weekend's action and its a mixed feelings from me. While there seem to be lots of action in both the sprint and the full race and kept me engaged the track limits were a joke, especially these extra penalties post race. The system does not work, they need to rethink it. Put gravel traps, barriers and walls back in place. I don't want to see drivers getting hurt but I do want to see them handling risk and I do want to see them penalised (by the track not the stewards) when they get it wrong. I think that is part of the reason some folk look back at previous years and think that current racing is lacking a little something compared to years gone by. In the "old days" (and you don't have to go back too far), there was a lot more jeopardy and a higher probability that a car would not finish, whether that was from a mechanical issue or crashing due to pushing the limits too far. Feels like that's all been sanitised a little bit in the track design and rules and regulations. I think now they have the cost cap in place, they should remove the restrictions on number of engines and gearboxes used per year. Let the teams decided for them selfs what the correct balance is in terms of money spent and performance gained and replacement parts.

@cdco, yep if I remember correctly the rear dampers and springs are stiffer on SC Evora compared to the NA Evora, fronts are the same. Stiffer rear I think would lead to a bit more oversteer balance but doubt the change from NA to SC was big enough to notice unless really pushing on.

Thank you for the update @#84. Can you give any more details on what work you did to the gear box and where you sourced the parts from, how much it cost etc...? My gearbox is currently broken (lost 4,5&6 while doing a track day) and waiting on diagnosis as the car garage is busy at the moment, so I don't know what's gone wrong yet. But would be good to have some idea of upgrade parts for when the garage get round to looking at my gearbox.

Any feedback regarding quality of components from Win Ace vs OEM and also weight difference?

Thanks for the info folks. To me it's a little disappointing that the weight is not closer to the target weight.

It's an Alpine branded camera and should be one of their off the shelf models not a custom made for Lotus job. So searching for an Alpine camera from other sources might come out cheaper than one sourced from Lotus.

100% agree with @agentdr8

Initial reactions are, I'm not happy to hear they exceeded the weight target. But ... any idea what other comparable cars weight? 2500kg sounds like a lot but if its less than comparable competitors then I can forgive them.

Ohhhhfff they just made one of the most gorgeous cars into a bit of minger! Great they are out doing some extreme stuff with the Evija but could we have a lap of the standard road going version please?

+1 for ES Motorsports

My 2p on this subject ... I don't really care how many Lotus have sold and if its a financial success or not. For me this was always just an engineering show of force and marketing exercise to relaunch the Lotus v2.0 brand after Geely took over. So from my point of view I don't care if they sold 1, 10 or 130. Just get one fully fledged production car completed and do the rounds on Top Gear, EVO etc ... and get people excited and frothing and gain some new Lotus fans and write off the loss as R&D and marketing. From what I remember didn't the original Bugatti Veyron sell at a massive loss? VW group just wanted to see what could be done if you gave engineers a blank cheque. Similar to the Lexus LFA and possibly many other examples ... None of those are considered a failure, everyone still looks very fondly at them, even though some of them didn't sell in high numbers and some of the them didn't make any profit. So I don't see why the Evija can't be in a similar vein?

Two articles written by the same journalist. Seems like an OKish first drive article a bit lukewarm rather than boiling hot. I was hoping for a bit more emotion.

I think the Evora (especially the GT4XX versions) is different enough to the Emira that it won't be effected if the market for Emira is softening and prices are reducing.

Thanks for the tips and yep have prepared my self for a big bill

Another person to add to the broken gear box club ☹️ I was having a lovely day at Bedford Autodrome on a track day, really gelling with the car and improving my skills and getting faster…. Then half way round a lap I went to select 4th gear and released the clutch, felt something snap and then got no drive, I lost gears 4,5 & 6, the others 1,2&3 are working fine. I limped back to the pits in 3rd and left the car there and got the train home. I have an 2010 NA Evora with CR box, so I guess that one of the “dodgy” ones.

Cleaning the MAF sensor is easy: Remove the zip tie if you have one Remove the two screws holding it to the air intake tube Unplug the MAF sensor. Use proper MAF cleaner (I believe general purpose electrical cleaner is not suitable), spray generously to clean it and let it air dry should only take a few seconds. Refitting is the same as above but backwards.

Echo what Mik says regarding change to power delivery. I have an NA engine and other bits a bobs to him but the end result is the same ie my changes let the engine breathe more. I felt the same greater sense of urgency to the engine and felt the same stronger top end he describes and it makes you really want to chase that redline!

Yep echo what Jon said above; I tried both Touring and Sport at the LDA, it's not a massive difference but it is noticeable. The sport is just a bit more firmer and direct and the touring just a bit more softer and better for everyday use. Both are totally suitable for a fantastic sports car like the Emira, both will send you happily round corners and neither will feel harsh over bumps. The difference is less than Evora S1 NA damping (softer and beautiful on an open road) vs Evora Sport 410 damping (stiffer and beautiful round a track).

Have a chat to ES Motorsports they can help you out with the mods they did my car, tell them Jay sent you. Larini, 2Bular and Komotec are the most common exhaust suppliers for Lotus bits and BOE are the most common (only) NA induction kit suppliers but are based in US. Although ES may have their own solution they can provide? When I first got my Evora it had 3rd CAT already deleted, Lotus sports back box, otherwise standard. It certainly sounded a little bit louder and fruiter than other Evoras and is a worth while change as its relatively cheap to do. It's just replacing a the 3rd CAT with a bit of tube so any good exhaust place should be able to knock that up. Otherwise I believe both Larini and 2Bular have suitable products. But if you want to go the whole hog, I have BOE Fab induction kit, Larini exhaust headers (removes the initial CATs), down pipe and Y collector, sports CAT in place where the 3rd CAT usually is and the Lotus Sports back box. This gives it a fantastic noise, louder and richer and way more drama without being too asbo. It passes most track day noise tests (just) and is tolerable on long journeys. The indication kit can be expensive to get hold off as its shipped from the US but in my opinion is well worth it.

Any one know which teams have ordered a Emira GT4 and which competitions they will be entering in? Was watching the first race of the WEC in Sebring and thought would have been nice to have the Emira competing in that too. From what I understand Emira is a GT4 car and I think in WEC the lowest class is GTE? Any one know what the difference is and if Emira GT4 could be adapted to enter GTE?
