Question. Is there a valet mode feature?

When I had my Audi... and had it tuned by APR... I would set valet mode... so it could not be thrashed and would not do more than 70mph and the turbo would not give full boost either.

I am starting to give this kit more serious thought now... because I don't see myself parting with my car for a good while unless any acts of God were to occur.

"Chris – Here is a fuel injector for your supercharged 328i. We sell 4 different flow rates. The 550cc is the most popular.

Talked to Bruce at fiveomotorsport and said these have the same spray pattern, and are the slim type. I also mentioned VF Engineering to them and they said they are a customer and right down the street. Could these be the secret injectors?

Not to toot my own horn but, I TOLD YOU SO!

I did a bit of research on the S85 beforehand, this is awesome news! rhombus , anyway you can propose this injector to Roman@ESS so they can test it? If this fits, I have found my kit!

I talked to a five0motorsports engineer back in January about their S85, the technical info on the spray pattern didnt match. They are a 10deg cone width. OEM is 20deg.

Per ESS "We have tried the 380cc version of the S85 injector from Bosch (used in an Audi TT225 model). Exact same spray cone and pattern as OEM S65/85 injectors. These did not work well. The spray angle on these was around 10 degrees, the N52 ones are around 20 degrees."

The OEM injectors have the following spray characteristics as I measured them:
alpha e20
dual 7 cones
delta 90
gamma 15

Damn.

If fiveomotorsports makes these custom injectors as far as the nozzle goes, can't they be drilled in a way to have the 20 degree spray pattern?

The OEM N52 injector has a 3d stamped plate on the nozzle which has 6 holes in it in a V pattern (3 for each spray cone). The plate is laser welded to the injector tip. The holes are small, they look like they are made with an EDM process for precision.

I have attached pics I took when testing the injector spray pattern (dual cone and forward spray angle) and of the nozzle. I am out of town on business so I dont have the injector with me to take a better pic of the nozzle to show the holes.

Is the flow rate based on the solenoid and internals inside, nozzle hole size, or a combination of both? Perhaps combine the stock nozzle with a body of one of those injectors listed. The nozzle dimensions should be the same, and if they can be separated from the body, I don't see why they wouldn't work.

I just bought a complete set of used N52 injectors on eBay for 35 bucks. I'm gonna see if they can be disassembled and talk to FiveO to see if they can Frankenstein an injector.

Also I'm wondering if the nozzle design on an E60 injector is the same? Also wondering if they are, do they flow more, same, or less. Can anyone chime in on this?

I have a feeling with ESS being so busy with other projects and kits, that it will be a long time if ever to come up with a solution for more power than the VT1+ kit can currently deliver. It will be up to us to find a solution. If we can get the flow and spray pattern correct, it will still take time to test them out, develop a tune based on setup, then finally release an update.

Sounds good. Make sure they know that the spray pattern must be exactly like OEM for it to work on this application.

[vha27]

Rhombus, did you say you had the injectors from FiveO but aren't using them due to idle issues?

Wow that's great I hope you have success towards the injectors your looking for. I think we all need it and I'm definitely waiting to see more power out of this kits. I'm glad that there is a following for it.

[vha27]

As a quick update, I received as set of stock N52 injectors. The spray nozzle cannot be removed/replaced.

Can somebody please test the N62 injectors... Honestly I'm shocked nobody has. Kind of a no-brainer to test those first.

I have put over 6000mi on the kit so far.

hi rhombus, whats the mpg in city now? does it decrease a lot? thks

there's also the V12 that came with valvetronic. N72 or 73 or something?

Direct injection, though. Think of it as two N53s with valvetronic.

[hassmaschine]

are you sure? it was the 1st engine to use Valvetronic (I just can't remember the exact engine code). I'm pretty sure they didn't combine Valvetronic & Direct Injection until much later. They had to shrink the size of the valvetronic components in order to fit it all inside the head, which didn't happen until the N55.

I don't think that's correct. The N73 does use valvetronic and direct injection and I don't think there was ever an N72, unless it's a euro variant I haven't heard of.

The N62 is the only other BMW engine that I know of that uses valvetronic and electronic port injection, just like the N52, but obviously I could be wrong, BMW makes a bunch of engine variants we never see in the U.S.

[hassmaschine]

you're right - N62 was 1st. N73 came after, I had them mixed up.

Hopefully the N62 has something that will work, but since they are both 0.5l a cylinder, I'd bet VE is similar and the injectors are close in size/design.

Except the N62 had a lot of different sizes, from 3.6 to 4.8 so I'm hoping the larger versions have higher flowing injectors. I haven't looked into the details though, differing part numbers, etc...

[hassmaschine]

4.8, yeah, good point. Wouldn't be too hard to cross ref part #s.
