    Porsche updated their RSR race car for 2019 to defend their FIA World Endurance Championship title. The brakes, clutch, and suspension remain the same. What is the main change? The new 4.2 liter naturally aspirated flat-6 motor. Porsche went to bigger displacement: This is interesting. Why? Because the GT3 street car follows the race car. Displacement in the GT3 has yet to go above 4.0 liters. Actually, back with the 997 generation the GT3 saw 4.0 liters so a displacement increase is due just as the RSR shows us. Porsche really has no other option to get power other than to increase displacement and increase revs. We are about at the limit of the motor. Does this mean the 992 GT3 will get 4.2 liters? Maybe. The 992 generation at some point will likely see 4.2 liters. Porsche may be holding the 4.2 in reserve for the 992 GT3 RS because Porsche is Porsche and that is what they do. Is this the end of the line for the naturally aspirated flat-6? Just about. There is another option nobody is talking about though for the naturally aspirated motor to continue in the GT3. The vehicle from Weissach has undergone improvements in all areas and will replace the successful 911 RSR with which Porsche won the manufacturers’ and drivers’ world championship in the FIA WEC as well as the Le Mans endurance classic (France) and the IMSA races at Sebring and Road Atlanta (Petit Le Mans) amongst other events in 2019. In developing the new Porsche 911 RSR, substantial insights were garnered and adopted from the extremely successful race outings of its predecessor. “Since 2017 the 911 RSR has yielded us more than 20 class wins in the world championship as well as at long-distance series in North America and Europe. Our job in the development was to make a very good car even better. The engineers at Weissach have perfectly implemented this in every aspect,” says Fritz Enzinger, Vice President Porsche Motorsport. “We never rest on our laurels,” explains Pascal Zurlinden, Director GT Factory Motorsport. “We’ve extensively analysed all factory and customer campaigns with the Porsche 911 RSR. Our engineers noticed room for improvement in a number of areas. We have made significant progress in the development of our car for the next three-year homologation period, especially in the complex areas of driveability, efficiency, durability and serviceability. Ninety-five percent of the car is new. The only components that we’ve kept unchanged from the predecessor are the headlights, brake system, clutch, driver’s seat and parts of the suspension. Tests so far have run excellently. We’re already looking forward to the first races of the 2019/2020 FIA WEC season.” With the repositioning of the tailpipes, space has been made for an optimised diffuser. The distinctive component at the rear of the Porsche 911 RSR now generates even more downforce. Thanks to the optimisation of airflow at the front and the sides of the Weissach racer, aerodynamic efficiency and stability have increased significantly, thereby further improving the use and durability of the tyres during racing. Focus on the work of drivers and mechanics Driveability and serviceability are critical factors in long-distance racing. For this reason, Porsche placed particular emphasis on these aspects when developing the new 911 RSR. The cockpit has been reworked with the focus on better usability. In this regard, extensive feedback from the Porsche drivers proved invaluable. Like with the predecessor, the body made of carbon-fibre reinforced plastic can be swapped out quickly and thus ensures efficient pit processes in long-distance racing. To give drivers added protection, the active and passive safety elements in the Porsche 911 RSR have been overhauled. The proven collision warning system allows drivers an even better overview to detect approaching prototype vehicles early enough. The optimised roll cage, the FIA side impact panel in the door and cage as well as additional impact protection for the legs improve the passive safety in the event of an accident. Other features include the removable roof hatch and the rigidly-mounted racing seat featuring a six-point safety harness for the driver. First race outing in September 2019 “We’ve been working on the concept of the new Porsche 911 RSR since 2017. The first designs were created using CAD software. In August 2018, the best racing nine-eleven to date completed its first kilometres on the factory’s own test track in Weissach,” says Pascal Zurlinden, describing the important milestones in the car’s development. Over the following months, the factory team conducted numerous tests. Seasoned Porsche works drivers took turns at the wheel of the new 911 RSR. Parallel to this, the aerodynamics were fine-tuned in the Porsche wind tunnel. “Another milestone was our long-run in March 2019 at Le Castellet, where we included the works teams from both the WEC and IMSA. We covered more than 6,000 kilometres over 30 hours without any technical hiccups. The drivers and engineers were very satisfied. The car received its racing homologation on 1st July,” added Zurlinden. World premiere at Goodwood The most spectacular 911 of all time makes its world premiere on 6 July at the Goodwood Festival of Speed (Great Britain). The Porsche 911 RSR will also celebrate its race debut on the British Isles – at the season-opening round of the FIA World Endurance Championship (WEC) at Silverstone on 1 September. Prior to this, the vehicle of the current manufacturers’ world champions will face rival manufacturers contesting the FIA WEC GTE-Pro class for the first time at a two-day prologue in Barcelona (Spain) on 23/24 July. The Porsche GT Team will field two works cars at eight rounds of the 2019/2020 season with drivers Michael Christensen (Denmark) and Kévin Estre (France) as well as Gianmaria Bruni (Italy) and Richard Lietz (Austria). In the IMSA WeatherTech SportsCar Championship, the switch to the latest model will take place in the 2020 season. In North America, an additional two factory-run Porsche 911 RSR will fight for the GTLM category title against competing manufacturers. For customer teams, the vehicle will be available from the 2020/2021 FIA WEC season. For the first time, the factory race cars from Weissach will be decked out in two different designs: The typical Porsche white will continue to be the dominating colour on the No. 91 car. Added accents include a centrally-placed red stripe extending from the front hood over the roof to the rear apron, as well as red side sills. Grey highlights on the side complement the clear and dynamic design. On the No. 92 car, the white and grey colours are reversed. The rear wing and the wing mirrors are black instead of white so that fans can differentiate between the two.

    Post the logs. I would hazard to guess you sucked up the muck at the bottom of the fuel tank and it clogged something along the way. You would hope the HPFP rail screen would catch it unless you removed the screen and drill out the HPFP for a VERY small increase in HPFP aka the ol false VTT HPFP upgrade/fix they sold.

    All VTT does is cast shade and spread FUD on competitors products. See new N54 HPFP product thread or anything that could take away a single sale. Don't feel like you are singled out, this is all they do on the forums. It is is not casting shade and FUD it is insulting anyone who disagrees with them or posts an opinion that is not 100% in line with them. They are hands down the least professional company I have ever ran across. They could not do worse PR for themselves if they tried. At least you don't refuse to refund money on product not delivered for 6+ months ;) Everything @SteamSpeed has released so far seems to be of decent quality, there is no reason to believe this is any different. Edit: I think Sticky's forum rules are that for a vendor thread you can remove Tony's BS posts if you ask him. Maybe you have to actually make the thread vs. him?

    Yes, we are 100% sure Tony at VTT does not work with us, and has no direct knowledge of our products, our manufacturing, etc., so any thing he claims about us or our product is just a guess. Much of what Tony has said is false, and should be treated as misinformation. For instance, the turbo pictured is in fact twin scroll, not single, so sticky, the original title was correct, please fix it back. 😉 We will provide further detailed specs later on when we are ready to make an announcement. It is also kind of funny that Tony is publicly admitting that some other company, Zage, and not VTT manufactures the GC "Game Changer" N55 turbos, and that "his" Zage-manufactured turbos have had serious quality issues, ie. high failure rates. Also, there isn’t anything special about adding branding in housings; it certainly doesn’t enhance performance. When you are using someone else’s turbo tooling, and they are making turbos for you, as Tony already admitted is the case, generally you only have to change one of the molds to add a logo, so you might pay a tooling fee to the company that owns the housing design of $1-3k. Congratulations! You paid and extra few thousand dollars to have special branding on the housing design that is owned by another company. We've designed and manufactured our own custom housings before, we've also built turbos using some off the shelf components. Anyway, Tony seems to prefer to tear things down. We prefer to build things. In that spirit, we won’t spend any more energy on this thread, unless someone has legitimate questions, or otherwise needs our help. This should be obvious, but one company bashing a competitor is not a good source of information. Look for our official announcements on the forum, FB, or our blog, or call us if you have questions.

    The more HPFP options the better. DI only is what everyone wants. The reason people use PI 99% of the time is it is MUCH cheaper than upgrading the DI system given the current options and vendor. This is not the only HPFP solution coming out this year. Competition is good for the consumer. It drives prices down. Having a single vendor offer a product is not good for anyone. If you bring a simple product to the market you have to assume it will be knocked off in a short amount of time. It is what it is. Price it correctly so knocking it off will not happen or price it and then drop the price when the competition inevitably shows up. Look at FuelIT! They continue to innovate and offer new products as people do DIY youtube vids for stock bucket walbros and save themselves $350 bucks or companies like precision race works etc. starts offering a very similar fuel products at a slightly lower price point. There is no use crying about it. This has been going on for ages and will continue. Competitors spreading FUD on a product that is not released is very unprofessional. If it is a failure they will net more sales at the end of the day. Let's just wait and see how this does and how long a new HPFP lasts. Anything else is just wild speculation as there are not enough data points to make an educated statement of how well the product works and what HP it supports on 100% E85, how long a new HPFP will last, or how long the product will last.

    As the title says.... I did a stupid and forgot the car was running in the laneway, and let it run completely out of gas. Then of course, all of the hvac, stereo, lights, etc were still on and the battery went flat. Charged the battery, got gas, got it restarted, everything good....not so much. Now, whenever I do any heavy acceleration, it get misfires. Light to moderate acceleration is just fine, but as soon as it gets above 4k RPM, misfires again. If I continue to accelerate hard, the CEL will illuminate and I need to shut the car on and off again to stop the misfiring. Codes are cylinder misfires. So, my questions is, what did I fuck up? Where to start? HPFP? LPFP? Injectors? Plugs? I don't want to start throwing parts at it until I get a bit of direction. Thanks for your help! I can post data logs or specific codes if need be. (Bimmergeeks ProTool) Cheers.

    N54 engine is in the E46 engine bay. I may have to do few custom modifications in the engine bay. just a few issues, nothing major.

    I could have got an E91. But, my goal was to keep the e46 wagon and swap an engine with more power. I love the body style and the way it looks. Initially I looked into swapping a LSX or S54 but eventually picked the N54 since you can make more power for less money. And I believe N54 platform could be almost legendary as a 2JZ. Furthermore, I'm hoping to document the swap so it would be helpful for someone else who is looking to do a similar swap. Learn from my mistakes. :laughing-rofl:

    The overboost with underboost code makes me think the DME isn't seeing boost from the JB4 hence the 30FF. I'd pull the JB4 completely off and go from there, scan codes from the OBD instead; Clear the existing codes and see what pops back up. If it is an issue with the JB4 itself, this would be a good time to upgrade to the G5 board; The G4 has been obsolete since 2011.

    It's still in beta testing so I wouldn't expect there to be a warranty. They're not going to warranty the HPFP that's for sure.

    Well, I did see something in Chinese that referenced the B58B30TU mentioning the (presumably new) X6. I am just mystified why BMW would refer to an engine that has not been produced as a predecessor. On the other hand, the plumbing in this engine with 3 pumps is daunting, I cannot fathom replacing the plastic parts as they fail.

    Full forged internals eh? Pistons, rods, and crank. This is going to be some interesting stuff when people start going larger turbos.

    As it says, "The design of the valve lift control system has not changed in comparison with the B58TU engine". They call the part #4 a 'Gate'.
