If you're in this boat of deleting DI you're part of the reason this platform isn't moving forward.
Firstly, let me say this is a debate and not an argument so don't get your feathers ruffled;
Do you really believe that adding PI to our platform, a backwards technology according to you, held this platform back? And by that I mean, we had a lack of innovation and progressive advancements in other areas of the platform specifically due to the addition of the supplemental PI? You do remember where we were before that time, right? People were running four M1 meth nozzles through various areas of the intake tract, apparently that is DI doing its job according to you. It wasn't until people kept blowing their cars up this way that people were willing to turn a leaf and try supplemental PI which works far more reliably and is used on all the top power producing N54's today. It is excruciatingly clear and has been for years, that our fuel system has been the largest weak point of our cars without an easy solution, the drive train following immediately after. No matter how fancy the technology is, it sucks and has sucked prior to the shotgun in the peak fuel delivery department. We have a peak fuel problem, not a technology problem. The newer occurrence on the technology timeline does not solve our peak fuel throughput issues. We were capable of supplemental PI the moment we had the Procede or JB3 and probably sooner, yet nobody messed with it because there were lots of sissies, most of those people aren't even around anymore. And all of this is being said in the face of the HPFP failure issues we were plagued with for years. Its good you can limp your car home, because most people actually needed to do that, in fact the first 335i I ever drove as a loaner died on me from a failed HPFP. Great times to be DI it was not.
If you remember that shop undercover performance, they said they had the car running on port fuel only using their intake manifold and the ProEFI, their problem was money and interest. It may have slowed down the shotgun, but the shotgun already took 10 years from the time the N54 was out. If you think a decade is a normal time frame to get to where we are now, you're wrong and its evidence that DI only had plenty of time to push the limits and did not. People like Jake Yamona have no reason to spend countless hours digging around for something we don't need or can't use. Nobody built hardware because there was no fuel, they said it over and over, the hardware is the easy part. So it makes sense to me there is no reason to build the shotgun or spend 100k+ designing a new HPFP when there is no backlog of big single, big power, big wallet guys who will buy it. DI caused us to be too little, too late for big risky moves like that early on. You should also remember that AMS left our platform because of this same reason, fuel. Now that we have PI fuel, everyone and their mom is now flocking to the N54 to buy and build a single turbo kit, this creates an audience for performance shops to target creating more opportunity, its just a damn shame that did not happen when the people with money who actually bought these cars new still owned these cars. That is what makes the M3/M4 so much of a better platform, there is actual progress being made and people with money to buy those mods. All you gotta do is look back for occurences of people being interested in an upgraded HPFP and you'll see just how long DI has kept us from being where we were the moment people started using PI spacers.
Somebody already brought this up, but it's the same as ditching fuel injection and slapping a carburetor because you can't understand fuel injection.
Who doesn't understand the problem with our fuel system? I hope everyone understands the problem by now so that analogy is not the 'same', it would be akin to saying the sky is blue, therefore the problem is our DI system.
If this is turning into a dick swinging contest betting mortgages I'm out, I not getting into that. I'm not rich like you guys. But for fun I'll wager $100 with
@doublespaces. I believe Tony has the fastest DI car as of now and actually has balls to race somebody. I'll put $100 against any PI only n54/55 car that will run Tony. 1/2 mile, 1/4 mile, whatever.
@Tony@VargasTurboTech you up for this?
The reason I made this point is because most people would not make that wager even if they could. Ask Tony what the best way to make north of 900whp is today, yesterday and five years ago. He will tell you that Port Injection is the most realistic answer, in fact, I've seen this stated on multiple occasions by Chris.
Saying you're going to wager me $100 to race a PI only car that doesn't exist is like gasoline guys saying electric cars will never compete while at the same time making sure they never have a chance at going into production. Lets give someone a chance to put a stand alone on their car and run PI only and you'd just be flat out wrong, DI has a limit even with the double shotgun. You might be able to limp your car home better, but as I stated, who cares. I'm talking about peak power delivery not fuel efficiency, emissions or daily driving amenities.
So to keep this apples to apples, you could start by replying with your explanation on how you can make our DI only fuel system flow more
peak fuel than an equally thought out PI only system, with the hardware available today, or yesterday, or any day prior for the last 10+ years.
