Reviewing the logs from last night, I was seeing 5, maybe 6 psi consistently with the filter on. The only change between the logs was putting the filter on. |

If you have the 9 psi pulley and the Si trim then you should be seeing 14-15psi without a filter. By only getting 11.5-12 means there's something else wrong. It has to be a boost leak, belt slip, or pulley sizing issues.
I see you have a lightweight crank pulley. Tiny increments in that will make huge moves up top. Start there.

So you have a 3.15 Jackshaft pulley and a 3.00 supercharger pulley? With that combination and the 2.85 serpentine pulley you should be making an additional pound of boost so really you should be seeing 15-16psi without a filter. The filter has shown to drop the boost down by 4psi so you should be seeing close to 12psi with it on. Something is definitely not right. Can you confirm with a caliper the size of your pulleys?

I’m at 8PSI with 9lb pulley and Si. Elevation plays a factor but no leak pretty sure we tested when I was at 7lbs with stock 8lb pulley. Sounds like turtle’s filter is giving a huge drop.
How long have people ran with no filter just screen? The idea terrifies me with rubber belt dust getting in boosted piping seems like a matter of time before it finds it’s way through the valves into cylinder but clearly huge gains to be had. I remember somebody explaining something I believe to Patrick about if you change to small pulleys it can over power the filter somehow decreasing boost? Don’t remember but elaborate if that phenomenon rings a bill. Anybody tried doing their own tunes? I would play around with pulleys and filters more if I could be tweaking my own tunes otherwise it’s too much of a hassle

If you're concerned about running just the screen you could get it tuned with the screen and then install a pre-filter for daily use. The pre-filter I tried (Filterwears) cut my boost by 5 psi but it can be removed in about 10 seconds if you want to increase your boost level for race situations. I don't remember anyone mentioning anything about too small of pulleys over powering the filter but I'm old and my memory isn't that good (that's my excuse and I'm sticking to it) You have to be certified by Ecutek if I'm correct in order to be able to use their tuning software and most tuners lock their tune so you wouldn't have access to it without their permission.

I'll be taking a hiatus for awhile for a short deployment, so I'm not ignoring anyone, just under the ocean. I'm hoping some R&D gets done for a better intake setup while I'm gone. I will happily contribute whatever and however I can! This thread has been absolutely fantastic in leading the way for the A2A setup and figuring out everything together! Thank you all! See ya on the flip side. |

Thought it would get a higher peak figure with the higher rev range and shift into a higher range for the following gears, probably overthinking it lol |

Everything's been upgraded to better stuff like bearings etc. I'll be doing some pulley changes once the E85 tune is sorted on current gear, so basically it's had impeller upgrade/bearings etc.. it had the 9psi stillen pulley on it already so guessing 500ish wheel HP then see where the fuel pump/injectors are at before upgrading the pulleys. (I got the Aeromotive 340 and Idx1050's, so guessing pump upgrade needed here). |
