is your excessive VE at low load around 2000-3000 rpm?

I was worried about removing the pulse dampers as well when I upgrade the fuel rails, so I also picked up a pair of the Radium ones that mount directly into their fuel rail. Super nice and compact.

interesting to see if pulse dampeners will do anything, keep us posted I have found that playing with injection end angle had more affect on this than altering the cams Also, I had this spike back when the engine was stock with unmodified fuel system |

We are partially back....
Had some requests to bring the pictures back.. but due to hd failure I've lost quite a lot. I was able to recover about 1000+ pics.. so everything up to 2018 should work.. |

Wow... I had not seen this thread before.
Amazing build! It seems incredible you were able to do all that painting without a booth. Superb detail. |

Ok.. I re-did all the missing pics as best as I could..
Didnt bother with screenshots of the tuning maps.. but if anybody does want to look at it.. just reply and I'll do my best.. |

So.. we are off with some updates..
Lets start with the rest of 2021... Did my first track day... Meet the FIRM. Florida International Rally & Motorsport Park How it went you ask ??? Well.. out of the whole day I had maybe 20min of track time.. Mostly doing runs back to the "paddock" to make a change and back out.. Just went too soon.. as I was getting knock left and right. Lunch hour was as well, spent fiddling with the computer... |

After the fiasco of the track day.. it was time to retire the 8yo hard rubber.
Tire rack has really fast shipping.. 2days after the order and this showed up... A set of Hankook Ventus R-S4. I've heard a lot of good things about the longevity and traction.. so this was the choice. Picked up a welder too... As it was about time to start learning TIG. This was my first attempt welding AL.. no prep.. no experience... This was the result with some practice.. As a practice, I welded up few of AL, Steel and Stainless cubes. weldmetalsonline.com has ready to go and clean kits It was now time to man up and chop up that Cobb exhaust. I needed to weld up the holes around the cat and weld in the V-band. I backpurged the pipe as best as I could.. Last but not least.. we got another member to our family.. No ride in the subie for him yet.. but he's working out the courage. Seems like the car is loud for him. |

Slowly catching up to current state..
As the center console had 3 different materials/colors it was time to fix that. Disassembling was and still is a PITA.. but everything had to be taken off. Almost as fluffy as alcantara.. almost. Still undecided about the gear shift trim... so might do that one as well one day. Oh.. and here is the doggie a bit older.. with a vintage Penguin Computing plush toy.. |

Nice. Very nice work. My brother and I have done this before as well. Just not to the extent you and your team have.. WOW.

Meet meth..
Misinformation leading to my mistakes .. so you dont have to repeat. Lets start with rule #1.. AEM meth kits are ****.. (never had one.. but read so many bad things on the meth forums, so stay away from that one) Rule #2 Some companies lie on pump ratings. Given that most of them use the same Aquatec 5800, some rate at 160psi and same at 300psi... ~160psi would be the correct number. Most meth kit mfg will say.. put the nozzle 6" before the throttle body.. This is wrong... You need to put it as far as possible from the throttle body. This gives time for the meth mixture (usually 50-50 with water) to cool the air and get absorbed. Depending on effect desired its best to put it right after the intercoler. (that is if your intercooler is efficient or big enough to cool the air charge) If your IC is not.. then you can put one after the turbo. There are also ways to increase your turbo efficiency by spraying pre-turbo. Here is a chart of possible nozzle placement.. (just missing the manifold location) Best setup for knock supression is direct placement in the manifold in each runner. This guarantees that each cylinder sees the same amount of the mixture. Couple this, with the after intercooler nozzle(s) for best results. You'll get the anti-knock properties from direct injection plus cooler air charge, which should also increase your knock threshold. This was where the old 2 nozzles were. Given this.. and the knock I was seeing with really low timing, it was time to put few holes into that manifold that I spent hours and hours polishing and cleaning up.. I've ordered a Prometh kit.. with a nice manifold and all.. Very pretty, aluminium with stainless nozzles... or is it ??? The nozzles I ordered were about 1/2 the size of my Aquamist nozzles. Given "the rule".. the smaller the nozzle the better the atomization.. Started testing, made some vids.. (thus crappy pics) So for ****s-and-giggles I wanted to see how this compares to my old Aquamist nozzles. This is how they flow at lowest duty cycle... If you pause for a second you'll see 4 jet streams.. Here is a pic of Aquamist at 50% duty cycle. (rated at 510cc and 440cc @160psi) I've cricled the mist and the nozzle.. so you know.. you could see it... (Oh.. yes.. the Aquamist at its lowest duty cycle still sprays a mist..) And Prometh at the same DC. (rated at 240cc @160psi) You be the judge now.. But wait.. there is more.. After seeing such ****ty results from smaller nozzles, I've decided not to use them and ordered a new kit from Aquamist. Putting away all nozzles Aquamist and Prometh back into a box.. (actually trying to return them.. but after restocking fee and shipping I'd get back $50, cant return the nozzles, just the manifold. So maybe at least they are good to water a veggie garden?) |

After about a 1.5 months.. the Aquamist kit arrived from England.. yay !!!
Was so excited, and wanted to see how the flow compares to the Prometh.. as size wise they were pretty much the same. Took out the Promeths out of the box.... to see this. But wait.. there is more... (filter) And more... Even the nozzle itself had rust !!! 3 out of 4 nozzles didnt flow at all.. The one that did, was just dripping. Now.. It would be unfair if I didnt check Aquamist nozzles.. so I opened them up as well. (The rust spots you see on the cloth, are from cleaning the Prometh nozzles..) As you see ZERO rust or dirt. Here is an over all test with 3 Aquamists, ranging from 240cc - 510cc against a 240cc Prometh. Pressure wise .. its just tap water.. at around ~50-70psi. Here is why the Prometh is such an inferior product. Despite the ****ty atomizations pattern for its nozzle size.. its made from 3 different metals!!! (steel, stainless, aluminium) The spring and filter arent even stainless !!!! Now.. thank you gut feeling. Back to install. Here is the after intercooler nozzle. (to reduce IAT) Aquamist manifold. And the individual manifold nozzles. |

Hitting image limits.. thus the post splits..
And here are the results. On average there is a drop of about 15-20F. Was expecting a bit more.. but it will do for now.. (maybe will go to an even bigger nozzle in the future) Notice how the IAT sensor lags... Ah yes.. I forgot rule #3. Always, always check your pressure after installing the nozzles. Mine was at 130 psi with 4 nozzles !!! Bumped it to 200-210. (as per Scott) Got this gauge from usrallyteam.com... I've picked the owner's brain quite a bit.. so the info you see here is from him. Thanks Scott !!! |

I can speak to the horrible nature of AEM meth kits. I ran one of their progressive v3 kits on my sti. It was using 4 of the smallest nozzles Devils Own sold. I had a set of Radium dual injector tgv housings modified so the 2nd injector ports were running the meth nozzles. I'm not exactly sure what failed. Could've been the controller or maybe the solenoid/check valve. It got stuck open and running full blast. Ended up lifting a head due to how much water/meth was in the cylinder which couldn't be compressed.
Ended up having to rebuild my iag closed deck short block after only about 3k miles. F the AEM set up. I've used an aquamist kit in the past with great results. That aside awesome build man! Last edited by Black90tsiawd; 04-18-2023 at 08:50 AM. |
