We had the opportunity to run a Dom 3 XTR here on a car that had a few of Blouch's turbo chargers installed previously. All these charts are run on an 06 STi with absolutely no changes to the car other than the turbo itself.
We are in the process of installing a Blouch 2.4" 3.0XTR on another vehicle as well, so the results will be posted in this thread shortly. We will also be tuning a 2.5R (Non-XTR) with the new 10cm hotside change.

Is funny comparing your graphs to IAGs.
On your charts you clearly see that the old DOM 3 52lb spools faster than the newer DOM 3 XT-R 55lb; but on IAGs the newer version kill the old turbo on spool and power . I would like to see the old DOM 3 with the big 10cm2 back housing, I am starting to think that the stupid wheel does nothing. I remember a long time ago that I asked someone knowledgeable if the weight of billet wheel had anything to do with the spool up time, the answer was NO, I wish I could find it. |

What it will do is help with response, and boost recovery after a gear change (assuming not FFS). Think about it, it is science, and all makes sense. |

So the DOM 3 XTR spools slower than the old DOM 4?

Seems to make sense with the significantly larger exhaust housing. Any possibility this car had a pre-turbo exhaust leak or a boost leak?

Im sure tuning has a lot to do with the results on these turbos. just because X vendor shows X gains and X spool doesn't mean the turbo isnt functioning properly.
it is possible Jorge had a slightly better approach to tuning the turbo at IAG |

i was thinking logically this will technically get the turbo to spool faster with a smaller housing? |

To be honest, the IAG comparison seemed way too good to be true and made me wonder if it was done in the same gear or even the same platform (04-06 STI or 07+). People always want the magical turbo that will spool faster AND make more power. Sadly that almost never happens. Physics tends to win over in the end -- Ed |

yeah, its tough to push air through the same size hole faster while still being able to flow more air overall.
our subaru community seems to focus more on the compressor than the turbine cause we've been stuck with 7 and 8 cm for so long. the turbine is the true shaper of your powerband. you cant use the compressor to its potential if the turbine wont let it. |

Hey, I just tuned my DOM 3XTR for pump gas and the car is running great with no det. I noticed that the Defi EGT Gauge is climbing up to 9 though. Is 9 too high?

Damn right when i'm about to go rotated. Blouch why do you always do this.
Now i have to rethink what i want. Quote:
I had a hose pop of the compressor side of the turbo one time and ran the 20g unrestricted to 32-33psi doing a 70-130 pull an empty interstate. Thank god i run stupid amounts of meth (900cc of 100%) probably saved the motor. I pulled the log and only got -2* pulled from 5500 on. Morale of the story, no fuel cut past 24psi....just be careful duder. |

Unfortunately the car with the regular 2.5R with the 10cm hotside was an engine job, so we're awaiting his break-in. We'll be tuning this car on Monday.
The first car we installed a 2.4" 3.0XTR on is just about read after doing pistons and a FMIC as well, so that car will hopefully get tuned tomorrow. We'll be doing another 2.4" 3.0XTR in a few weeks as well. - Pete@EFI |
