If you haven't read the previous post I made on maxing out the stock fuel system on E40 please go to my profile and scroll down until you find it and have a read.
This post is going to cover the first part of testing with the
Xtreme-DI LLC
Upgraded HPFP and Bosch Motorsports +30% injectors.
Just so it is clear, here are the changes since the baseline testing from last week:
- XDI HPFP35 Upgraded High Pressure Fuel Pump
- Bosch Motorsports +30% Flow Injectors
- AEM 500psi MAP Sensor **
- Dizzy Tuning's MAP Sensor Adapter
- Turbosmart 14psi Wastegate Actuator
** The 500psi MAP sensor is what I had on hand, normally we would use a 5BAR map sensor but I didn't have any pigtails handy for our Motec 5BAR sensors so I had to improvise. Obviously this is OVERKILL but it got the job done. For customers that are looking to go over 29psi we will have 5BAR kits on hand. Still overkill but it's a quality sensor and that is more important.
The fuel remained E40 to keep testing consistent from the baseline. Unfortunately it needed a little bit more ethanol for this setup but I will get more into that later.
In addition to testing the new fuel setup we are also testing the Turbo Technics S280 and see what it's max capability is, and we found it. We had this thing SCREAMING and push it's to it's absolute limit to where it just wouldn't make anymore power even with increased boost pressure.
Dynograph below is comparing 100% stock fuel system max safe power, to the upgraded pump/injectors on the same turbo.

The reason why I decided to start at lower boost (28psi at 3500rpm) and linearly raise it up (35psi at 6500rpm) was to keep the torque down on the stock block while also keeping the clutch from slipping. We got up to 420wtq on one of the pulls and the clutch was struggling to hold the power.
I mentioned above that the car could have used some more ethanol for this setup. Reasoning being is that I was starting to see some knock in the upper RPM. So I had to bring timing down but raise the boost up to make the power. Likely the same power could of been had with a little more ethanol, 1-2* more of timing, and about 3-4psi less boost. But as I mentioned I wanted to keep the testing consistent so we stuck with E40.
Likely with better charge temps (We were seeing 110* on the dyno) and less humidity (it was 85% humidity last night), a little more ethanol, and some added timing. We could have hit the 410-420whp mark. Though that still means the turbo is well outside it's efficiency range.
𝐓𝐇𝐄 𝐅𝐔𝐄𝐋 𝐒𝐘𝐒𝐓𝐄𝐌:
For clarity this is all being fueled by Direct Injection. There is 𝗡𝗢 𝗔𝗨𝗫 𝗙𝗨𝗘𝗟 on this vehicle. This is 100% being controlled through the factory fuel system.
The car met commanded fuel pressure without problem through entire testing last night. I have attached a picture below (second picture) showing the commanded pressure (blue line) and actual pressure (green line). We are raising the high pressure demand with RPM as the pump flows MORE fuel with MORE RPM. Commanding more pressure than you need at lower RPM can just cause stress on the on the injectors. You only need to use as much pressure as needed to stay on your AFR target. You can see in the third picture below AFR was on target (12.0:1 AFR) the entire pull within 2%.
So we definitely have plenty of pump, and the injectors seem to be handling the combo just fine. I do believe with a little more ethanol we would reach the max of the injectors at 400whp on E60ish. Can't really say that for sure without actually doing the testing on it but we are going to wait for our next turbo to get here before we push this fuel system a little further. The goal will be to make 370-380whp on straight E85 out of the pump just to see if the fuel system can handle it. Which means 90% of the customers out there will be able to run E85 straight out of the pump without having to mix on their Sub 400whp car.
Now, I see people asking "Why wouldn't I just run Aux Fuel / Port Injection. It's cheaper, and it cleans the valves". So here are a few points on why we are looking to take Direct Injection upgrades as far as possible on the platforms we support.
- This is a simple bolt on affair, no need to tap wires into your stock engine harness, and no fuel lines or hardware to install. You simply remove the stock components and install the new upgraded parts. I was able to install both the injectors and the pump in less than an hour.
- There aren't two systems that need to be tuned. When you add AUX Fuel/Port Injection you are trying to make two ECU's work together that don't talk to each other. They are completely separated.
- No need to flash the injector controller or disconnect/turn off when switching fuels. With a full DI system that can support your two different fuels you simply fill up with whatever fuel you like and map switch.
- Aux fueling (for now) is controlled by a system made in 1998 (Split Second). This is batch fire, and not a sequential system. So it does not spray when the valves are open they all just fire at the same time regardless if the valve is open or not. This causes "puddling" and changes the state of the fuel from an atomized state and enters your cylinder as a "shot" of fuel versus efficiently combining in the cylinder with the fuel from the DI side.
- We, as well as most tuners charge more for aux fuel tuning. If you do the pump/injector upgrade it is covered in our standard tuning rates, no additional cost.
- Carbon build up is less of a factor when you are running Ethanol. The only reason you would need to do a fuel system upgrade like this would be to run more ethanol. With ethanol there is virtually no carbon deposits to bake onto the back of the valves.
- This is getting us a step closer to being able to provide a full flex fuel capable system through the stock ECU. Meaning you will be able to fill up with any fuel between E10 and E85 and the ECU will compensate automatically without switching tunes. No ETA on this obviously as there is another party involved that needs to provide the ability but we will get there.
Do I still recommend Port Injection / Aux Fuel? Absolutely. I can't say that it doesn't work because we have proven that it does work all the way up to 700whp. However I recommend that the DI system be upgraded ALONG WITH aux fuel when the fuel demand for just the DI system can't be met. Allowing your engine to get the majority of it's fuel from the DI system allows you to rely on the port injection less, which means you fuel the engine "MO BETTA" and it's less stress on the fuel system overall.
𝐓𝐇𝐄 𝐓𝐔𝐑𝐁𝐎:
The Turbo Technics S280 is by far the best bolt-on turbo upgrade for the Fiesta ST to date. If you are looking for quick spool and (realistically) a solid 370-380whp turbo then this is it. We were seeing 30psi at 3500rpm, no other turbo on the market has the fast of spool and still be 350whp+ capable.
Yes, I made 400whp, and there might of been another 10-15whp in it with some more ethanol and timing, but for the turbo size I don't see 35psi of boost sustainable. Based on the wheel size and the turbine shaft it will definitely put stress on the turbo. I could be wrong, it could last "FOR-EV-ER" [/Sandlot] but to keep the turbo and the stock engine happy lets call it 370whp as the mint area for this turbo.
If you're not looking to make that much power, it's still a solid choice because you aren't sacrificing spool or low end torque with this turbo. Say you just want a little bit over 300whp, you would only need 25psi to hit that mark and it hits 25psi at 3200RPM. The stock turbo hits 25psi at 3000-3100rpm, so virtually zero added lag.
So, if you want one. Myself and
Ron Miller
have them on our websites and you can order today! (Yea, I didn't use proper grammar order there but I do what I want
)
𝗪𝗛𝗔𝗧𝗦 𝗡𝗘𝗫𝗧?:
We do have some more fuel system changes to test along with some even bigger injectors to get us through the next 100whp (400-500whp). However we need to make some changes to the car itself.
- Clutch was slipping slightly on these last pulls with the big boy torque. So we are working on some single and twin disc clutches for the Fiesta ST. More information about this soon.
- The turbo is pretty much capped out and we aren't going to be able to continue through our next phase of testing with this turbo. So we have a Peron G-Series Turbo kit on the way for the car, and I will be pairing it with a G25-660 w/ .92 A/R turbocharger and that should get us through the foreseeable future in testing.
- I have a longblock en-route along with a transmission to launch our Engine and Transmission Program. Just like the Focus ST/RS and Ecoboost Mustang we will have a full Shortblock and Cylinder Head package available and likely a full turn key longblock for our customers to purchase.
The overall goal is 600whp. Yes, a lofty goal for the 1.6L but who is to say it will be a 1.6L it's whole life
. We have some things in the works, like we always do, but I have no doubt we will get there and who knows we might get there on 100% Direct Injection Fueling
