Finally got the tune done for my blouch dominator 1.5xtr turbo! feels amazing. power delivery is much more linear than the previous sti turbo i had. i have included graphs of my old dyno plots just to show you how wildy these numbers vary. i find it funny that the car is clearly faster now with the larger turbo, yet it happens to be the lowest reading dyno sheet.
and before you say anything i know you cant compare differeeny dynos, but heres proof for the non-beleivers! anyway, i want to give a big thanks to Ron for tuning this beast, and all my friends who helped me make this possible with their help, time, knowledge, pizza and beer.

yes sir. 60k miles on it. spent the first 20-30k miles at stage 2, then from 30k-60k with sti turbo
its funny that it says it made more power with the sti turbo according to these dynos LOL |

3400-3500 in 3rd gear, which is right where i was expecting it to be. i think its a lil sooner in 4th but i dont really use 4th.
Ron said we could have easily pushed it further, but suggested i leave it here if i wanted my setup to last. which i most certainly do as i can not afford a new engine right now |

nice numbers and even better powerband! thats exactly the kind of power band im looking for in a turbo and i thought the only way id get that was with a TS setup or a teeny tiny 16G XTR with a bigger hotside.
wonder how this would be on a 2.5 with a 10cm hotside? hmm |

I cannot wait til I get my Blouch Dom 1.5XTR 3" inch inlet, 10cm hot side, ceramic coated installed on my built EJ257 with WRX 2.0L heads. I've been enjoying seeing how this turbo spools and the power curve for everyone else. I'm excited for my new setup. |

spool is good. obviously not as snappy as the vf43/39 i had before, but not bad at all. In someways its a lot better in the sense its easier to drive, smoother power delivery, more off boost power/ throttle response.
before if i floored it at 2500 rpm, i would be fully spooled (18psi) by 3000 rpm. Now with new turbo if i floor it at 2500 rpm i wont be fully spooled till 3450 rpm (18psi). I was worried it was going to be like 37-3800 or even as bad as 4000 but i was pleasently proven wrong! i really like this setup, i just wish i could push it more, but i fear my engine would esplode. I already have random misfires under light load/idle we havent been able to figure out. one day when i have a built shrotblock ready to put in, ill turn up the boost and see if she can hit 350whp on pump Also, i see no point in the 10cm hotside when i have an EWG. that and the topspeed dyno comparison actually makes the 8cm look like the superior turbo regardless. if this wasnt my DD and i didnt mind taking the intake manifold off again, i would have gone 3" inlet and bigger intake. My MAF is already hitting 4.8v on logs so its safe to say ive nearly maxed stock MAF way before the turbo is even close to being maxed out. lastly, the numbers may be some of the lowest posted for this turbo, but dont let that fool you. the SHAPE of the curve awesome IMO. Even though my "before" and "after" dynos read the same HP. my injector duty cycle is about 90% on 750ccs and my MAF maxed. SO theres no way my 560 cc injectors at 90% were making the same power, unless im missing a huge part of the equation. Last edited by 07VTRex; 07-18-2012 at 07:08 PM. |

I have been debating a lot lately about removing the front aero guards and/or the rear strakes (the ones in front of the rear wheel)
I am going to keep the rear bumper pieces i think, and definitely the side skirts. But should i ditch the add-on aero or leave them? help me choose people!!! |

Why didn't you go with the 2.5xtr? The 1.5xtr is not known to make much more than an OEM STI VF.
The curve of the virtual dyno will be different than an actual dyno reading. So wouldn't put too much weight into it. |

Also all of my virtual dynos generally have the same shape as my dyno pulls that I have done, this was with my stock VF39 as I havent dynoed my Dom 1.5 that I have. But was making 380whp VD at 21 psi and ~365whp on airboy on the Dom 1.5 with 10cm EWG. But unfortuanity this was with broke ringlanding as I thought source of my oil smoke was turbo so I replaced my VF with Dom, later I learned it really is internal. |

Looks solid. Definitely spools better than my Dom 1.5 on my V7 EJ207 but that's the higher altitude (3500ft) and the smaller displacement. Im making 280whp with this turbo but limited to 18psi while I try to figure out why its misfiring at higher boost (possibly coilpacks).
Definitely a much better turbo (with 3-400rpm more lag) than the VF30 I had before. Kind of wish I'd gone with the twinscroll version. |

I would like to how he came to that conclusion as well. Unless he is referring to torque maybe. S

People are making good power with the VF52 on pump, along the same lines (in some cases better) as the 1.5xtr on pump. Which the OP graphs also re-affirms. With that being said, the 1.5xtr will excel with higher octane gas.
If I was concerned about spool and running the car on pump. I would have went with a different turbo. False. The 2.5xtr will make more mid to top power than the 1.5xtr, both on pump and on better gas. True on the 1.5 spooling quicker. Last edited by Fierysun; 07-19-2012 at 02:33 PM. |

I call BS. Went from a VF to a Dom 1.5, the Dom has much more power potential. Went from a nearly maxed-out 300 whp to 355 whp with room to push it later if needed. I'm holding a flat 18 psi out to redline, no VF does that.

Oh and as far as the dyno graph of the 8cm vs 10cm that Top Speed did. The 10cm held more boost/power longer than the 8cm. Both spooled about the same only difference was top end. I've been over that thread a hundred times. I'm excited for my new setup and hope it's everything I've been expecting it to be. |

the blouch website has a misprint. the 1.5xtr is rated at 47 lbs/min and the 2.5 xtr rated at 49lbs/min
Why did i choose the 1.5 over the 2.5? The difference is negligble. I wanted 350 whp before i realized my engine didnt want to make that much on stock internals. I am not gonna push the 1.5 as far as it should be pushed so why go even bigger and have even more lag? in hindsight, i got ahead of myself and should have built the motor first. I should have waited and done it all at once, or settled for a maxed out 18g setup. oh well captain hindsight.... i do not think the size of the intake is going to effect spool at all. i think it is completely unrelated, and it is the exhaust size/shape/length that matters, but i could be wrong. all in all i really like this turbo, i just wish i had of planned better instead of being impatient as always. just because a vf series might have the same peak hp number as this turbo does not mean its as fast. its the area under the curve, integral for you math people, that is what makes a car fast. Peak numbers are just peak numbers and do nothing to describe the overall shape of the power curve. Even without understanding the theory, anyone who has ridden in a tuned VF subaru knows they fall on their face afer about 5000 rpms and make jack **** for power, temps rise, efficiencies fall, bad times are had by all i dont have access to e85 where i live, or else i would already gone down that road. best case scenario is to build the block and see how far pump can take this thing I am very curious as to how my setup compares to other similar setups. i too am running a solid 18psi from 3400-6700 rpms. it feels good, smooth and linear. i really like this turbo, i just wish i had an ej257 or 207 |

The Dom 1.5 is not a big power producing turbo on pump. It drops off even more at the top than the 2.5. Your better off with one of the higher quality 20g variance, than the 1.5. Quote:
The 3" inlet actually hurts spool with a stock location setup. 2.4" is the way to go. Last edited by Fierysun; 07-19-2012 at 04:46 PM. |

Both setup identical except for turbo. Dom 1.5 10cm 2.4" vs stock VF39 both on meth. Its kinda apples to oranges (VF is maxed out, Dom 1.5 is just starting to wake up) as VF is 25psi tapering to 15psi and Dom 1.5 is solid 20 psi and it will need higher boost to shine but limited by fuel when tuning was done. Both are 3rd gear so spool is little late on both and I gain couple hundred RPMs later by changing cam timing on Dom 1.5 so dont get to caught up in later spool. VF39 tune made 322whp on dynojet SAE correction, havent dynoed Dom 1.5 yet. Both of these logs are uncorrected as I didnt record temps of VF run.
Major mods is GS 38mm EWG using 4port boost control, Perrin big maf with velocity stack, Invidia dp, ebay exhaust, stock long block with stock TGV, meth, lightweight pulley and ACT streetlight flywheel, GS PnP manifold, turbo inlet. As you can see after 4800rpm the Dom 1.5 leaves the VF39 Sorry not trying to thread jack you there, just wanted to show comparision of VF39 to Dom 1.5 Last edited by bswilmington; 07-19-2012 at 07:59 PM. |

Looks like a good safe tune. I've ran the dom 1.5 at 26psi on a built 2.5, made right around 400/410 on E. On pump we made it to 22.5lbs at I want to say it was 360/360. This turbo flows a whole lot more than a vf39, take it to altitude and there is no comparison.
