4. Petrol.

1700cc at what PSI? I have seen threads like that as well. The problem that I have is where did the information come from? Did they take a 5 BAR standard flow test and then multiply that number to get the CC? Because if they did then the numbers are not correct.

i wonder if these would work... fuckin mustangs gettin all the shit.

DeatschWerks 1700cc Fuel Injectors 2015 Mustang Ecoboost Set of 4

Oh baby. Go to fine me a OEM one for possible fitment.

ill have my boys at ford keep a look out if they get a broken one and ill have em send it ur way... doubt they will get on tho, cuz i dont think theyd be failin already...

What kind of power are those mustangs putting out anyway?

stock?? or modded?

Modded of course. I wonder if anyone has taxed their fuel system yet.

uhhh i know there is a couple big turbo ones pushin 500hp on stock blocks... im pretty sure tht was stock fuel system but not 100%

Good to know. These look like the HDEV 5.2. I'll order one and see if it will somewhat fit out head.

ur gunna order a stock one or the new deatchwerks one?

Dustin Jones, gearhead. Not sure what method he used, but I'm sure it factored in full spray window (without factoring timing).

Looking forward to seeing the results...thanks for your work here. ;)

Gearheads... What do they know? No offense.

He's the guy that drove around with a full size O-Scope on his dashboard and a trunk of wiring going to under his hood for measuring injector PW and shit like that.

Fuel system on ecoboost mustang supports 500whp on pump gas, just fyi. Excited that you are working on this, i have a million diesel shops around me and ive been looking for some used injectors to see what they flow and if anything can be done to improve them. Im getting tired of running out of fuel at 20psi on the cs turbo on e30.

PS Mountune makes bigger DI injectors for the 2.3 EB

The injectors and head design are completely different tho
Even looks like the bucket they use for the cdfp has a roller on it, interesting that this design hasnt come out sooner with all the problems vw had with cam follower wear

EB market >>>> MZR DISI (MZR DISI is dead after all)

jussayin.

retrofit is our only hope

Amen. That's what this is all about...

Power output can very alot between cars. Variables like perfectly seating rings, CC venting, fuel quality, timing used and amount of exhaust backpressure (to mention a few) dictates what power that specific engine makes. And IDC can be taken well beyond 130% on some cars where they cause fuel cut very quickly on others when exceeding 100%.


My car made 360-380awhp from 5400 to 6500 rpm on 25% E85 and stock fueling system (VD numbers though but they are quite accurate) at 11 AFR. This equals 450-475bhp on 20% drivetrain loss. Probably close to maxing the injectors out but it ran quite well, no fuel cuts.

So 550bhp is almost 100bhp more

I assume the statement was more along the lines of how much fuel can it flow, how much potential energy is stored in this amount of fuel and how much power could that be? Hell just a degree of timing could be 15+ Hp on some setups
@littleloogy; did you mean 550 each or for four?

Mountune doesn't make injectors. They just rebrand other ford injectors from a Jaguar I believe.

I wish. 550/4

They kinda look like VAG/TSI injectors. It looks like you bored out the injector bore to make it fit.

what do any of the last two dozen posts have to do with the HPFP.

see why we need a new thread loogy? :)

doo eeeet already. We'll get Raider to clean it up.

Exactly! And I would think that when they state "550bhp capable", that would be on a more normal setup, with "normal" timing and boost. What we do to our cars is optimizing it as much as possible. So if timing on a normal setup is 10*, then we could gain ALOT by bringing it up to ~18*. So possibly 600+? *dreaming a little* :)

So long as our ECU can drive them, I'm willing to test bigger injectors on full corn....Kind of in a good spot to do it anyways.

Wheel or crank?

Bhp.

So probably close to what we have already.

Have you ever seen a stock fueling mazdaspeed with 495whp / 440awhp? Me neither

He said 550 brake; you mean to tell me that our drivetrain loss is around 10%?

I'm here to tell you I'm excited about possible injectors. Been lurking on all your threads for awhile. I knew there was a reason why.

More like 460 on a 3 which is probably around an 80-100 Hp increase over stock. More importantly it would be enough to cover 95% of builds.


Edit: all of the above is ricer math I pulled out of my ass.

Read my post again

550 * 0,9 = 495
550 * 0,8 = 440

whp = two wheel drive = ms3
awhp = four wheel drive = ms6

Yeah, you're saying that MS3 drivetrain loss is only 10%? Always thought it was a bit higher.

Here in Australia we've seen stock 3's dyno 150-155kw stock (190kw crank) which is about 15% loss...

6's usual around 130kw (low 20's loss)

Standerd internet drivetrain losses are

15% fwd
20% rwd
20-25% awd

Stock ms3 s dyno 220-230 so right at 15%

Yeah that's what I was thinking too; 15% seems more reasonable.

That would put 400 WHP cars at about 470 crank...So 550 BHP injectors are about 17% larger, and would see 60-65 WHP gain (roughly)....Or close to 350 WHP on full E85 (assuming 300 WHP is all that can be attained; I forget exactly how much I was able to make).

One other thing that needs to be considered is spray pattern and piston top design to match. I'd assume that the Ford injectors would have a superior spray pattern, but I'm not sure.

It's definitely higher than 10%.
This is a heavy duty tranny. All you need to do is listen to it to know that. I wouldn't doubt it's closer to 20% on the 3.
