Scenario 1: A turbo upgraded S55 running straight E85 looking to produce 750whp could easily do so on EU5 injectors without upgraded HPFP's, upgraded LPFP, or PI. However, just as you would need to target high fuel pressure on the HPFP side when getting close to the limit of the factory DI injector you will still need to do the same when reaching the flow limit of the EU5's. This is primary cause of injector failure as we previously discussed. Scenario 2: The same vehicle and goals listed in scenario 1 with the addition of EU5's and HPFP upgrades will support the same power goals, but will do so without the risk of injector failure since upgraded HPFP's flow significantly more volume at a much stable and lower pressure. Unfortunately, since we have not completed testing with EU5's and Dorch HPFP solution for maximum power without PI, we can not say for certain what the safe limit on straight E85 is just yet. However, we can say with certainty that a HPFP upgrade is going to be required for big power applications as fuel pressure will begin to crash at those levels. |

Absolutely understandable, we only recommended running higher than E50-E60 with EU5's if it's available so you can take advantage of the ethanol content. If your ethanol content is restricted due to regional mandates, than we would still recommend running the EU5's if you have the ability to do so.

I tried searching, but couldn't really find a proper answer. What is the difference between the EU5 and EU6 injectors and are there different versions of each?

What other items need to be ordered with the EU5 injectors to mate it up. Kratos mentioned decoupling elements. Also what hpfp and lpfp are y'all going with? Is PI still necessary on stock motor with these fuel upgrades? Trying to gather info and create a build sheet and do more research on what's needed when upgrading turbos. Might pull the trigger in a month or so once I gather all info. My plan is upgrade turbos (undecided brand still looking into all options and talking with people who already have turbos installed), upgrade fueling to run on full e85 and meth for cooling if possible, upgrade dct clutches (probably ssp), stay stock motor (build down the road), stock driveshaft, and axles (maybe upgrade after they break) for now. Thanks! 🤙🏽
P.s. I have a build sheet already but it's way out dated it was created well over a year ago. I'm sure there's a lot of new products and newly found upgrades/ limitations so trying to keep my build as up to date as possible. Thanks ahead of time for any info provided! |

Can’t wait til my KRAS55EVO are installed on my car. SSR went with all your recommendations Dorch HPFP, primary injector upgrade etc. all this paired with a fully built motor (head build, pistons, rods, etc), port injection and new manifold. Really don’t know what to expect. Super excited and can’t to share with you guys in about 2 months once she’s all complete. |

Yes, you will definitely need to retune and calibrate fuel tables to accommodate for the larger EU5 injectors. We will forewarn you that this is not as simple as it sounds and requires an experienced tuner familiar with DI injector scaling if you want to retain good startup, drivability, and WOT characteristics.

It's understandable that they'll need to be tuned for from the aspect of injector scaling as you mentioned, and I only ask as I've read that EU5's require that injector calibration numbers be entered in ISTA when moving from EU6 to EU5's. I'll be doing a remote tune soon after installation but want to ensure that I can still drive to where I need to go without any adverse effects. |
