He has a sedan the Q300 hatch has only one muffler and its crazy on the highway at a constant speed. I hate being next to the dividers because sound just echos even more. When I go WOT the car sounds amazing and I get compliments like crazy but I'm really starting to want something with less drone.
*edit* I type slow. I also was considering the greddy sp elite but as xluben said price is kinda making me hold off. |

Me too. Q300 sounded fine going through the rev's but the horrible drone was killer. |

It is much louder than I anticipated from the "Whisper" but I am in love with it and will probably never change it. The thing that is awesome about it is that there is absolutely zero drone on the highway. That's their claim to fame and they got it down. I found mine used with like 5k miles for $600 which is pretty reasonable IMO. IDK if you have cats or not, but the catback has no resonators which definitely adds to the loudness. Putting a cat in would quiet it down substantially.

I'm catless. Have you had other exhausts on the car? I have a hard time basing my decisions on people's opinions. I've heard plenty of people say the Q300 is quiet and also that the SPT is loud. I think it all depends what you're comparing it to. I've had a few setups now, both too loud and too quiet, so I have a good idea what I'm looking for.

what about the ARK exhaust? Its about the same price range as the Greddy SP so its something to think about if you do decide to drop over 1k on the exhaust lol.

Hey Ben, just wondering what the figment was like with the FMS FMIC? Did you have to remove the stock crash beam? Trying to decide whether to get the FMS or the RacerX Fmic, the latter which I know retains the stock crash bar.
Also, do you find that the fmic causes more lag or lessens the throttle response?? Or is it something that is barely noticeable? |

On a 2011 you will have to significantly cut your bumper. All of the unpainted plastic needs to be removed, as well as about an inch of painted plastic along the whole length of the opening. Once you have the core mounted, everything else goes together well. The pipes/couplers/clamps seem well done. I've been happy with it (after spending 2 days trying to figure out how to get it mounted). I like the design quite a bit better than the RacerX. The RacerX is really making compromises to try and fit in with all the stock stuff in place. Smaller core, odd pipe routing, etc. I'd take the FMS over the RacerX just based on that. One thing to note is that recently ImportImageRacing (they own the "FMS" brand) got in a batch of intercoolers with the end tanks on upside down. From what I have heard, they are still selling these and have been trying to tell people it is normal. I would try and wait until they get another (correctly made) batch before buying one. |

Here are my results using Virtual Dyno vs. the actual Dynojet at MAPerformance. I have two different setups that I've had dyno'd at MAP. The first was with the stock VF52 (on E85) and the second one was the 20G XTR (on E85). Here is more info on the 20G XTR setup if anyone is interested.
http://forums.nasioc.com/forums/show....php?t=2338819 2011 WRX - VF52 - E85: Dynojet (MAPerformance): 339WHP Virtual Dyno (Dynojet): 338WHP 2011 WRX - 20GXTR - E85: Dynojet (MAPerformance): 462WHP Virtual Dyno (Dynojet): 463WHP The peak horsepower results are VERY close! The peak torque is different by about 5%, but the overall curves (both power and torque) look very similar. The main issues I see with people posting Virtual Dyno results are the following:

The other interesting comparison here (for some people) is the stock turbo vs. a bit larger one, the 20G XTR. This size (very similar to the Dom 1.5XTR) is something that many people probably consider when looking at stock location turbos and I haven't seen too many direct comparisons. I haven't seen too many people push this size turbo to higher boost (many are often run at 20-24psi), so often the results are not that impressive. When TopSpeed did the Dom1.5XTR testing, they pushed the turbo to similar boost and had great results as well.
What I glean from looking at these plots is that you can gain over 100WHP and 100WTQ when going from a stock turbo to this size turbo. You will probably lose up to 500rpm's of spool (ie. RPM @ 20psi) but peak torque will shift by nearly 1k rpm's. Often when you see turbo's this size having peak torque only about 500rpm's later than a stock turbo, it is because they are only pushing it to just over 20psi. When you push the boost higher you will typically see spool up at the same RPM but the peak will be further right. On the street it feels great, but it does hit later. There is gobs and gobs more power, but you do have to wait for it. Downshifting does wonders. It's much easier to stay out of boost, but when you get on it, it really moves. I love the setup and could never see myself going back, but be warned that it does feel different. No more flooring it at 3k and zipping away. You're better off downshifting, then flooring it, and then zipping away much faster I daily drive this car, and I love it. Plenty of usable power, and it comes on quick enough to be good for daily use. The stock turbo on E85 is an absolute blast compared to a bone stock car. Spools the same or sooner, and has so much more power and especially torque. The boost still drops off by redline, but you can get a very good midrange torque peak. The car will spool so fast for the power you can make. This is a great setup and tons of fun. It is very cheap to do, and it should be quite reliable as well. If you want more power, I would wholeheartedly suggest going through stages, rather than just jumping to something big and laggy because you want a big dyno number. You'll learn a lot more about what you really want along the way. Of course I'm sure there will be people who want to nit pick one thing or another in this post. These are just my thoughts on my results. I'm sure some people have spooled earlier or later, and some have made more or less power. This is what I've seen, and it's just one example. The only other word of warning is that with this power, things break. I've cracked a piston and shredded 3rd gear in the last year (but now I have a built motor and built tranny, so hopefully things last!). |

I am pretty sure I have seen your watermark somewhere... You wouldn't happen to be from MCB? I am 99% sure you are

Do you think the stock block on a VF52 with a tmic using E85 would have been reliable? I wouldn't push the tq nearly as high as you but somewhere in the 330hp 340tq range I hope is within reach and will still be reliable to get me through my normal commute. I never FFS or launch my car.

My opinion is its all in the tune, I was with a HTA68 / FMS FMIC @ 21lbs and my cylinder 3 went. Almost a week exctly after Xlubens went, 3-months later built stage-1 block and waiting on getting the tune. I was not running E85 as I do not have any around these parts, so I went with Meth HSF-2 kit.
I personally think it is all in the tune. I would never do this again. If you modify a subaru, be caeful. |

That's why if you build power you should have a block ready to go

The 09-12's can hold 400 tq pretty reliably, imo.

I just did this Friday (I'm only running 93 tho, no E85 where I live)... your analysis is pretty spot on. It feels like driving a n/a car- except when you down shift- then she stands up and stays with you till red. I've only driven it this weekend, but my gas mileage skyrocketed to 29. Before I was constantly teasing the turbo and burning gas because of it, now not so much. Something I certainly hadn't expected.
