NoFear matches up Pitt's Map1 [ 8.7 map 1 and 8.8 map 2.] So they managed to squeeze out about 1.5 psi more boost, nice. Guess that means that Lotus is bleeding off pressure in the stock config or bypassing compressor. Not bad, beats changing the pulley+ belt which is basically impossible to...

For those with ODB interface- is Boost pressure displayed in PSI ? If so what is the max boost pressure stock vs map2. Question is for both engines.

[ 4 screws to remove from the charge cooler to get to the sensor there’s actually 6.] MR69 are the intercooler bolts challenging to back out? Looking forward to impression/results, do you have a draggy performance meter?

[With all these extra power.. would anyone recommend going 305 ]. With some members braking axles trying to launch this car, adding more traction might lead to more problems- clutch, trans. Spinning wheels might be a good drivetrain relief outlet. I would wait until more members upgrade and...

[Sure the info-tainment system sucks, the brakes are slightly grabby, I hate the Emira key fob, ] Very true on all pints- has anyone looked into how to moderate the braking grabbiness...maybe a good topic for a new thread. (no keyless entry is a silly oversight in 2025, my first car with...

Suspect the entire drivetrain is mercedes and the M139 + DTC drivetrain is used in much heavier 4 door cars. Wouldn't expect the AMG axles to have any issue in the Emira's.

[the exhaust is mostly about sound, not power.] Well said, and I agree. With the stock exhaust, and exhaust valve fully open it's basically an open system after main Cat off turbo.

[It is only the I4 and only in Sport & Track modes.] I haven't made it 1000miles yet, so haven't toggled in Sport or Track mode but even in tour it sounds a bit artificial. Are you sure ?

Well, thats alot of detail :) [Map 1 was at 77 degrees out at 3.5K RPM feathered clutch dump] Sounds like a launch to me. What do you consider a Launch.? Just letting the clutch out completely at 3.5k-4k?

Coreyalert3 Thanks for posting draggy results. [Map 2 (93 Oct) Quarter mile dragy run no launch] What do you mean by 'no launch'? how are you keeping these run consistent? A 6 mph trap speed improvement is pretty good

wow, that's clean break. If everyone starts bring cars in for axel snaps, Lotus will ask dealers to start dumping the data logs, and start flagging cars. [ but the axle is the same part number as the Evora] Evora is lighter than the Emira, right? Have people been running 50 extra HP in the...

yikes - did the Axle actually sheer or break at u joint ? [Sometimes you fix one weakness just to discover another follows shortly behind. Better an axle to break than a Trans to grenade] Very true, and sad for people who are looking to tune the Emira. Thanks for sharing your story and...

[Promote the brand with movie placement. eg another Bond car. Just so people remember the brand exists.] Yes, Lotus's brand awareness team is asleep at the wheel. The Emira is a masterpiece; would pair well in a Bond movie. They also completely missed the boat with the US auto magazines...

[I’m just happy that someone came up with a way to improve the performance of our cars to now make them perform] I have another supercharged car, would really like to understand how this JB4 unit is 'creating' more supercharger boost? 2 psi is a lot. Unless Lotus has been venting pressure, and...

Lotus Tech's Losses Increased to More than $1 Billion Last Year The automaker now needs a cash injection to keep the lights on That's a huge loss for such a small company. Wonder who might be interesting in buying this poorly run brand/company next. VW?

[yes, but the market has spoken and 6 speed cars across the market are what collectors and enthusiasts really desire and really desire and will pay up for. ] Given their are almost no manual performance cars produced for the US market in 2025. Not sure this accurate. Ferrari , Lambo...

Maybe Lotus is detuning to 400Hp from ~420Hp. Then introduce an 'S' version with ~420HP -- lol

[ without updating the software - those values wouldn't change.] Some AMG owners are reporting different results (more than one). Perhaps some versions of the 2024 AMG cars have different software revisions. Perhaps Lotus really did detune the car with the latest, software update....

Found this drivetrain loss estimator to help us understand possible crank HP. Clipped the Front Wheel Drive transaxle drivetrain ; which is essentially our setups. 12.5 % for DTC and 12% for Manual. Drivetrain horsepower loss guestimator Front Wheel Drive (FWD): Generally has the lowest...

[We will do some back to back Draggy pulls and post the results once we get a kit installed on the shop car, maybe some dyno pulls as well just to show a secondary set of results.] Yes, would be great to have a second perspective (about this companies claims /dyno / draggy ) 95 HP from a...

[95whp increase on the V6 powered cars!] Understand how to squeeze more HP out of a Turbo car, but how is it really possible to push 25% HP out of a supercharged engine without changing the pulley or significantly reducing the charge temperature. I replaced the pulley on one of my supercharged...

[Can't void what you don't see. ] Well - modern cars log a lot of data (memory is cheap) imagine boost is ore of the logged data points. If you blow a cylinder head gasket and cars logs show you were running 36 psi of boost vs 30 psi there may be some push back on the warranty claim...

[nterestingly enough even if we go with that the TDI tune essentially adds boost so even if it was a formula looking at the Boost it should have come up with a higher number but right now it just shows 400] We'll all the data from members is helpful trying to pin down what is happing. So- when...

Interesting - click on the 'Infotainment HP thread' above. Perhaps your on to something. Some cars may have the Chinese spec in the US essentially the "mercedes CLA45 full HP. Some US cars may havethe 'software update' to a lower HP to 400 vs ~420. Eager to see what mine will hit, but it's...

Lotus F1 - were you able to observe the HP on the infotainment screen prior to taking in? Some US cars are showing more than 400HP- one guy reported 423 HP on the infotainment. If your car max's out at 400HP after update, then they probably reduced turbo PSI/HP. My car is at 350 miles - so...

For sure a v8 isn't coming anytime soon, look how long it took to get the Turbo into the US. I'm with you thinking 2029+ if an engine candidate actually exists today. I have a couple Mercedes AMG V8's they are awesome, however the engines are large, the trunk would likely need to go.

Been following this guy for years, he produces well edited videos and with good content. Brooks has a lot of connections and access to almost every high end car youtube.com/dragtimes Brooks confirmed 3.4s to 60mph (same as C&D) on an untreated damp road. Stated he made 3.3s pass as well, Nice.

Well that's a great video. Your club should help Lotus with their Marketing ! IMO Lotus's marketing team is asleep at wheel. By now they should have extensive high res asset library with cool back grounds for all car colors, vids etc for social media (yes, they have some but limited)...

So - how does the car sound without augmentation ? (with the entertainment system off)

Car & Driver posted a 3.4 to 60mph in a US car (very impressive). US cars may produce the typical M139 HP as in the CLA45s 416-423HP even though Lotus advertises 400HP. https://www.emiraforum.com/threads/jan-2025-car-driver-emira-amg-one-pager.5617/

Perhaps if enough people send 'feedback' to Lotus directly and when you visit Lotus service centers, they will provide a software update one-day. Maybe provde a toggle in a hidden menu so Car Review companies don't find it and call it out...

Certainly informative, sad to see so many 'American' car companies build cars outside the US. Japanese manufactures have already started moving down the desired policy path years ago with a good amount of cars already produced in the US. Surprised to see Mercedes is producing there New line...

Had those greasy drip marks too, cleaned once haven't seen anything since. Although I have had the car a warm environment yet.

Perfect. With the vents being a controversial topic and I'm personally unsure of specific purpose, I just asked Aeries if they are able to easily add two small slits to the top interior of the port. In a inconspicuous spot to try and mimic original slits. They just sent new pictures of the...

That's great picture, nice to see all the drilled aluminum. Think what Kitkit is saying their may be a bit of negative pressure created as air passes through the port from the wheel well. Which may be pulling air from between the liner and potentially some of the air from engine compartment...
