    I would assume it is getting enough fuel. With the tests we have done, there hasn't been any sign of KR in any of the cylinders. Logs have never looked so clean.

    I'm the consulting engineer working with Steve on this. The intake manifold actually flows a lot better than is commonly believed. Part of the issue with meth systems currently on the market is the quantity of fuel being distributed; the nozzles are primitive, atomization is sub par, wall wetting is a significant issue and all of those things cause droplet formation, which will end up being problematic when it comes to flowing fuel equally in the manifold -you HAVE to have not just good but great atomization. We did some testing on higher boost (VTT 2+ 19t uc) on E60 and increased timing until noise became steady. What we saw was interspersed random cylinder noise for a while, then once the threshold was crossed, almost a step increase to noise on all cylinders. In other words, we're not having issues with cylinder 1 and 6, AT ALL. This was repeatable. This is partly that the manifold is better than we thought, partly because most meth systems are not great at atomizing, partly because even the ones that are good at it are flowing so much fuel it just isn't going to work as well, but mostly because we chose the location and type of nozzles to really maximize atomization. These things are pretty much putting out a fog. So why doesn't everyone else do that? Cost, and limited flow potential. While we have a little room to grow, this design has a specific place in a build, certainly not the sky-is-the-limit designs, for that go with Tony's dual HPFP, port injection, or both.

    Wouldn't you be seeing knock in those cylinder if they weren't getting enough fuel?

    A PTE 6466 is around 1950$ retail compared to 2300$ or so for an EFR turbo. So 300$ really doesn't make sense to be cheaper when those builds on other platforms cost at least 3X more than what anyone has done in this platform. I don't think that is the case at all in my honest opinion. I'm going with the straight swap comparisons, twin scroll, same fuel, same car, same day. I've seen a few of them floating around in the supra forums directly comparing 6466 vs 9180. Plus, I'm not comparing their number to ours. I'm comparing their numbers to their numbers on their car. So it is all apples to apples here in the research I have done. I have driven an EFR on the street actually. I have probably owned an EFR before anyone else on this site and actually reviewed it with a full build back in 2012. The 6758 EFR was a great turbo. Until it blew 7 months later at only 20 psi LOL. BW didn't want to warranty it, so I said fuck them. Good turbo, but shitty customer service.

    Here is direct comparison of the GTX and some similar sized EFR offerings, again on a PI low compression platform. I've posted these before. But shows the EFR's are not leaving the GTX's in the dust at all. I will always go with Garrett over anything else given a choice.

    Wonder if anything will come of it. The head of Fifa is still chilling in his headquarters: Qatar will likely still host despite the bribes.

    Any info on how well pistons 1 and 6 are getting fueled with this? I know we have issues with meth distribution due to same length intake runners and curves in them for those cylinders. Port injection doesnt seem to have an issue with that, and I'm hoping this wont have issues with cyl's 1 and 6.

    Ive driven an EFR back to back after a swap from a Garrett GTX of similar size. The results were not that different. The EFR spooled slightly faster, but nothing that blew me out of the water. On the other hand, I do 100% agree with you that a big EFR on the N54 will be very interesting due to our high compression DI configuration. I for one and excited to see how it does.

    They stick with those turbos because they are cheaper and they may make a bit more power when pushed to the bleeding edge. Also, a lot of the comparisons were flawed (using open vs. twinscroll manifolds w/ different turbos), etc. Also, they are all low compression, PI motors that the power comparisons were done at 40-50psi. Our motor is very different. If you've ever driven an EFR on the street, you'd understand the hype. It's transient response smashes any of the PTE offerings.

    I agree with this too. But its new to this platform where most of those turbos have been tried. I like new things, always that excitement of seeing a turbo tried for the first time, as the N54 can extract some serious power from turbos other platforms cannot.

    The 9180 hasn't even been impressing others in supra/evo/STI platform. They all still stick with PTE 6466/6766/ and the new 6870. Still, I am interested to see it's potential. What can you do... That picture is something that I would think to see on e90post lol. If people want to be technical, this is the forum to put a full picture and have the real people here go ooh and ahh.

    Maybe you should go back and read. I AGREED WITH SOMEONE. I did not make my own post questioning the hype. I felt like it, but I didn't. I simply agreed, and added my own point. Bottom line, we do not make a single kit. so this effects us 0%. As I said another single turbo kit with any kind of manifold, let alone one already on the market, yawn. An N54 kit with a 9180, that on the other hand is exciting.

    That would require a manifold. My bet is it is a flange and half a set of runners. lol.

    Let's just say I'm not surprised you're dampening the mood when it comes to a potential competitor. I'd like to learn more about the manifold.

    The hype makes no sense. Nor does the super duper secretive I wont release photos. Um ok, why because someone might copy it, and then we have 3 CNC that will all flow the same on the market? The only thing I see that would be exciting about this project above other single kits, is the 9180. Besides that. Same same
