Put on a KillerB header last night!
Unfortunately the custom EWG setup wouldn't clear my downpipe so we had to improvise an EWG block off plate. I'll probably have to pick up a different downpipe to make it fit.

Quick speedo video with the KillerB header that I put on over the weekend.
50-100mph time on this is just under 4.3 seconds. I was in the 4.6 to 4.7s range prior. *Stock photo from RSD. Mine is actually a standard one with a custom EWG flange and dump. Just for fun I'll be going on the local Mustang Dyno at RS Motors this weekend. Any guesses what I'll make? |

So there are definitive gains from the KB even though you already ran a ELH?

The two pulls I did on video with the KillerB header were 4.27s and 4.28s One was a 1,2,3,4th gear (only 2,3,4 are used in the 50-100 range) and one was just 3rd and 4th but both had similar times (this is normally what I see, 2,3,4 is in boost the whole time, but has an extra shift while 3-4 has 1 less shift but is just coming into boost in 3rd at 50mph). |

Tell me more about your hesitation you are having. I have a handful of cars tuned with the CarBerry rom now and my wife's and the 7670 WRX both have some weird hesitation issues that I just cannot get tuned out no matter what I try. The logs don't show what the issue is and trying different things with fuel, timing and avcs and nothing helps the issue. It seems to come on around 2 - 5 psi. If you push through it its fine.
Speaking of avcs - on a dual avcs cars, to have zero over lap, the intake cam gets set to zero and the exhaust came gets set to 17*. At rest, zero on both, there is technically 17* of advance on the exhaust cam. Once you leave rest, ie, start driving, normal avcs mapping commands the exhaust cam up to 17 or more. More than 17 retards it giving you more overlap. In general that's used for spool up and then taken out by the time the turbo is spooled up. After that, at least 17* and in some cases a little more (say 20*) is held out to redline. If your cams just stay at rest all the time, I would think you have a constant 17* advance on the exhaust side. That probably isn't doing you any favors up top in terms of volumetric efficiency with your exhaust cams essentially opening a bit early. Maybe it really doesn't have that much impact but it makes me wonder. Has Nuke mentioned this at all as a possible concern? Would be curious to see what he thinks. It could possibly be related to your hesitation but its hard to say. I know when my car is still in warm-up logic, I have zero cam movement and if I start driving, I feel hesitation and loss of power in a similar area. Once the avcs comes on, everything feels normal. |

None of the other attempts fixed the issue, but swapping the cam sensor (on the Cosworth bracket, because I have an AVCS motor in my non AVCS car) cured it immediately. My car never threw a cam sensor code, but some people have seen this with the Cosworth bracket and had to shim the sensor. My car has single AVCS cams. The intake side has AVCS cam gears and AVCS cams (but are not functioning). The exhaust has NON AVCS cam gears and NON AVCS cams. To address the cam timing issue on the intake side we advanced the timing by one tooth. This will put the AVCS cams/gears approx where the NON AVCS would end up. http://forums.nasioc.com/forums/show...8&postcount=30 If I went back a tooth and was fully retarded I could probably get some more top end back (this is how the car originally was running), but as-is it should be similar to if I had NON AVCS cams. I don't think this had anything to do with the hesitation. It appears it was 100% due to the sensor (bad sensor or improper air gap I don't know). |

Interesting that the cam sensor swap fixed it. If I go back to the MAF based rom on my wfie's car, everything is fine. If I put it on the CarBerry rom with the exact same boost/fuel/timing/avcs in the same area, the issue is there and it does feel like misfire. I doubt this rom would pick up the cam signal differently but maybe its something to look at. |

I don't see why the AP would introduce any new issues for you. Should work great. |

I had my car dyno'd at the MNSubaru 10 Year Anniversary Meet and Dyno Day held at RS Motors on Saturday.
The car made 457WHP/ 422WTQ on a Mustang Dyno (for reference the car ran 10.9s @ 126mph the last time at the track). Here's a larger version of the plot: RS was nice enough to log the pulls on my AccessPort, so here's a Virtual Dyno comparison just for fun. I have the weight set to 3500lbs and the calibration set to "Mustang" and the numbers are pretty close. Change the calibration to "Dynojet" (what I normally use) and the numbers go to 525WHP. Compare that to my most recent road log and it reads 525WHP with the weight set to 3300lbs. Typically I've just been using the default 07 STI profile (same chassis and gearing as my car, but higher weight) and that makes it read 561WHP. No real point to all this, other than to show that dyno numbers (especially Virtual Dyno) can be manipulated considerably. But if you do have the correct inputs, the numbers can be very close and the curves look quite similar to on an actual dyno. The only thing I think I really need to take away from this is that the 3300lbs (3100lb car + 200lb driver) is likely going to be better than the 3550lb (3350lb car + 200lb driver) that I had been using in the past. The car was under 3000lbs on the scale at the track but that was with floor mats out, no tools, glove box and center console cleared out, no Recaro baby seat, etc. Around 3100lbs on the street is probably pretty close. |

Quick little comparison of the powerband on some different Subaru turbo setups.
All of these were cars run on the same Mustang dyno and the same day. Manually plotted in Excel. 457WHP - 422WTQ - 2002 - Subaru - WRX - E85 - 27.9PSI - 60-1 - 2.5L - 6MT, FMIC, EWG, etc. 343WHP - 360WTQ - 2008 - Subaru - WRX - E85 - 23.5PSI - 68HTA - 2.5L - FMIC, EWG, etc. 256WHP - 257WTQ - 2015 - Subaru - STI - Pump - 15.5PSI - Stock - 2.5L - Stock 204WHP - 192WTQ - 2002 - Subaru - WRX - Pump - 13.9PSI - TD04 - 2.0L - Stage 2 |
