    From Tesla's unofficial timing the prototype Model S was quicker around the ring by 20 sec than a production Taycan Turbo. Do you think they are lying? Why can't a prototype be quicker than a rival car around a track and break down? It's a prototype....what's the issue?

    Relax man. No need to get offended. If you look up Porsche made electric car ages ago. Wake me up when they start making $$$ and have a stable management.

    It's true Porsche, Ferrari or Lamborghini have never had a car breakdown on the 'ring during testing.... https://www.autoevolution.com/news/2021-porsche-911-gt3-prototype-breaks-down-on-nurburgring-spied-up-close-135717.html Everyone loves to hate Telsa but IMO it's unjustified. They are kicking Porsche's ass at the performance EV game and increased competition is obviously great for us consumers. It won't be long before Porsche responds with an improved car, then Telsa will respond, and the cycle continues.

    I wish they would have called it something other than the Supra, seems to be doing the name a dis-justice so far. Like a hall of fame athlete coming out of retirement only to realize the competition has progressed, and he hasn't.

    Is it fair to say that Toyota might have missed their mark with the Supra if todays Tesla and Civic Type R can not just come close, but beat it around the track? Maybe being to critical, but was kinda expecting more.

    Camaro SS 1LE is running 305 up front last time I looked a year ago. Also more than twice the engine capacity.

    what's misleading, they did a drag race, same time same track. They could have done more races like a rolling, clearly the mustang would have won that. Just a video showing launch and grip is a big factor.

    One important factor to bear in mind is that this race was very likely done at high altitude, over 5000 ft above sea level. NA cars lose 15-20% of their power due to the thinner air. Performance inevitably suffers...

    You either get to make it clear it's a prototype and get leniency on break downs or claim that you're faster than your rivals production car. Not both.

    Isn't it generally accepted to be okay that prototypes break down? Simulations only take you so far, you learn about the failure modes when things actually fail in real life testing. Tesla is slammed for running prototypes and then slammed when they fail, even though its okay that they fail.... its a prototype. Tesla can't win

    PorscheBoost wrote about the BMS (Burger Tuning) JB4 being available for the Porsche 991.2 9A2B6 3.0 turbo motor a few months back. Since then BMS has shipped plenty of JB4 boxes to Porsche customers and it is always great to read a first hand review. The review below is by PorscheBoost member @Aatish: Breaking this down into 3 different sections: 1.) Install 2.) Performance impression 3.) Daily drivability impression TL;DR: If you’re looking for a nice bump in power that doesn’t involve taking out your ECU and risking your warranty at a high level, then I would totally go JB4 route. Not sure how it compares to other piggy back units, however given the experience with my 991.2 C2 and my past dealing with BMS and the team, I wouldn’t consider anything else at the moment. Install TL;DR: - Relatively simple, in comparison with other units. - No need to remove bumper - About 30 – 45 min if you take your time Performance TL;DR: - Very noticeable increase in power - Not going to make your car a built GTR, but definitely significantly faster than stock - Logging suite and app are ace Drivability TL;DR: - Not jumpy or unrefined in any way during normal driving - No codes or issues experienced (so far) - Feels just as refined as stock Install Overall, not hard just requires proper prep and a slow pace. There are only 2 sensors, one on the Y-pipe and one on the intake manifold. Y-pipe is easy to access…intake manifold is more involved. Still, possible to do without removing any body panels. Only tool needed was an 11mm socket to disconnect the negative battery terminal. 1.) With a cool car, unlock car, roll down windows, and pop the frunk and engine cover open. Do not turn on the car (or let it run for too long). You do not want to work while the engine is hot/warm. 2.) In the frunk, pop off the top cover exposing the battery. Take 11mm socket and disconnect the negative battery terminal. This will cut power to all systems (including the DME and all the sensors). Optional step, though I’ve always done this when install piggyback tunes in the past. Lowers the risk of shorting something during install… 3.) In the rear of the car, remove the duct leading to the intake plenum. Pinch outside wall to flex the stiff plastic clip. This will allow you to slip the rubber off the retaining wall, freeing the duct. 4.) Pull on the top edge of the plastic cover to free from top corner retaining plugs. Once free, repeat with bottom corner plugs. Once loose, shift up and lift out, exposing the fans and their connector pieces. 5.) Pick a fan, and grab the connector. Push the tab on the rear of the connection, and pull firmly to release the connection. There is a retaining piece to keep the fans affixed to the frame. To release, pull firm and pinch the pin from underneath. Same goes for the clip wire. Remove fan and tuck the clip away from the opening. Repeat for the other fan. Make sure you note which fan is right and left. 6.) To remove the plenum, first unhook the release cable from its seat on the plenum. Then, firm lift on the plenum, releasing the pressure holds from the interior plumbing. Lift out completely from bay. 7.) Note position of the Y-pipe sensor. Practice releasing and installing the connector with 1 hand. Get a feel for how the plug releases and the behavior of the plug when properly inserted. 8.) Optional: Grab some lube (lotion or Vaseline) and make sure your hands are somewhat moist and slippery. 9.) Reaching the intake connector requires giving your car a minor colonoscopy. Note the position of the sensor and plug. Route the wiring harness with the brown and black wires near the connector area. Go in with a flat hand work your way down there. I have large hands, so I needed to do some squeezing (hence the lube). Get your hand behind the connector. Once down there grab the back and release the plug. Grab the JB4 female end and insert the DME end into it. Will take some finessing, but it is possible. Once that’s in, grab the male JB4 end and plug into the sensor plug. Make sure it’s securely attached (should not be loose). Once satisfied, slowly get your hand/arm out. Be careful not to tear any skin. Again, will require some finessing but it’s possible. Practicing with the Y-pipe connector and building some muscle memory goes a long way. 10.) Repeat connection steps for the Y-pipe (not as hard). Yellow cable wiring harness. 11.) Disconnect the sound tube on the left side, route the green wire through till it stops moving 12.) Inside car, fold seats back and pop the top carpet cover off on driver side. Just grab and pull firmly. Green wire should be there. Pull through completely and connect the OBD wire to the plug. Then plug into the OBD port, near the accelerator pedal. Once connected, push wiring underneath floor matt and into the side seems to hide. Reattach the carpet cover. 13.) Reconnect the tube if you want to. I didn’t. Tuck the JB4 unit into the right-hand side of the engine compartment. There’s a little space where it tucks nicely. Zip tie if you want to. 14.) Repeat steps 6-1 in reverse to reassemble the plenum, fans, cover, and battery. Once connected, start car and make sure no CEL. Connect to the app if you have the Bluetooth option. 15.) Go for a quick spin to make sure everything is well. There shouldn’t be any CELs or warnings… Will take a few miles to adapt, but you’ll notice a decent bump during the first couple of pulls. Once the car has some miles on it with the unit, it picks up in power and it’s very noticeable the change. Performance Initial impressions after install were nice, though a bit underwhelming at first. Car felt the same down low in the revs, however really picked up after 4500. JB4 was set on map 1 and driven for about 100 miles or so. Definitely became more noticeable after a days worth of driving. Pulled like a train throughout the range; no more fall off feel after 5000 rpm, like how it feels on stock. It pulls very strong once boost kicks in, all the way to redline. After shifts, the boost is held and it’s a noticeable pull when into next gear. Map 1 is a great starter map. Map 2 turned it up a notch more. Definitely a bit more pull during acceleration. The way to car picks up in RPM after 5500 rpm is legit. Stock, car feels like it’s being held back and falls off a bit. With Map 2, car keeps pulling hard till redline, and keeps intensity through the gear. I love it!!! The JB4 Bluetooth kit is optional. I would honestly not get the unit without this option. Worth the extra money; gives you a lot more control and ability. I’ve been logging regularly to make sure timing and AFRs are stable (they have been). Map switching on the fly is sweet. Very little lag in data communications; it’s super responsive. Auto-log feature is love and hate. I like that it starts a log when I do a pull, and automatically ends once I lift off…sometimes it starts when I’m aggressively passing someone though. Kinda annoying, though I’ll blame this on me. The manual log function works very well. Hoping to try E85 mixes in the coming week, once I burn through 1 more tank. I have about 300 miles on this unit in the past 3 days. Hopefully should have another 200-300 by next weekend. Drivability Cruising around how I normally do (sport mode, manual shift), car feels factory in terms of refinement. Definitely feels a bit more powerful, however everything is still smooth. Shifts in both auto and manual mode are still quick and snappy. No jerkiness or anything abnormal so far… Haven’t had any codes or CELs (knock on wood). Scan function from the JB4 app shows nothing wrong. Drove car through light rain (not by choice). Weather proofing seems to be up to snuff. If you’re concerned about compromising the refined feel of the car with this unit, I would not be too concerned. I used it all day for my Saturday rounds, and it all seemed to be business as normal (though it just moved a bit faster). Final Thoughts Overall, very satisfied with the JB4. Would definitely recommend this to anybody looking for some more performance, without the need to remove ECU. A proper flash tune may provide a bit more flexibility for performance gains…but this is more than enough for me. Performance bump with map 1 and 2 is worth it alone. The app and extra maps is even better. I can geek out with the logging software and the user adjustable map function if I want to as well, which is sweet. Was very satisfied with BMS when I had my Bimmer. This holds true with their Porsche offering. Excited to see how this platform develops as more people jump on board! Update 2 - Drag Strip Car was heat soaked from the commute over and the prolonged idling during staging. That said, it performed like a champ. No issues during the runs; everything was business as usual. Numbers Map 0 (stock) - 12.699 @111.00mph Map 3 Run 1 - 12.165 @115.11mph Map 3 Run 2 - 12.237 @115.66 mph IATs were at around 130-140 prior to each run (not ideal). Shoulda brought a fan to cool things off in-between runs. Oh well

    That's pretty sweet but for me I won't need it. Still cool for the off-road guys that you can get it installed at the dealer.

    I’m just wondering how the Camaro SS 1LE and Mustang GT PP2 are beating an M2 competition around a track. Shouldn’t the M2C be the most ultimate ///M car currently availible?
