In my opinion, a few of those pics are calendar worthy!

I must have missed the part about the drivetrain swap. Reading comprehension wasn't my forte on the SAT's. Regarding your points: 1.) LOL insurance. I bet you get giddy when you're not paying the premiums for an STi and yet have the ability to spank one if given the chance. 2.) Smart move. You saved that money you could have put to a STi and got something built for cheaper. You're really paying a lot more for that badge. On the other hand, people are too lazy to do what you did and will just put their money down on the STi because it's instant gratification. They didn't have to wait those 42 days that you did while your SF sat there waiting for its donor. Also, warranty. If something breaks, and it's still a few years in, just take it to the dealer and it's covered. With yours? Something broke? Upgrade it, and stock up on some lava soap. 3.) I believe I read something back there regarding Ian's Forester along with that JDM Forester STi (M type II) as you mentioned as your inspiration. I'm glad you really did it your own way. Makes a lot of us jealous on this forum. FYI, I haven't seen a heavily modified BRP SF around these parts. Hahaha... 4&5.) The sleeper is pretty much why this forum exists. It may be the only reason you really have to put down. I hope that today, you can look back at when you raced that EVO and lost because you pushed it too hard and just say it was worth it. Also, I hope you had the chance to redeem yourself from that day. Reading that part about losing to the EVO was heart breaking and I really felt for you. It was easily the best part of this thread for me, although sad, and nonetheless, very well written. I felt like I was there with you. 6.) Yes, the space. I couldn't agree more. Between me and wifey, multiple trips to Lowe's, Home Depot, and Ikea for a new house I couldn't imagine doing it without my faithful SH. I'm glad you were able to help others in those 9 days you were without power. 7.) I knew about the weight, but I didn't know it was that much lighter. Quite the illusion. I think the only things that the STi has going for it are the aerodynamics and lower center of gravity. So, I'll just leave this here: "Aerodynamics are for people who can't build engines." -Enzo Ferrari 8.) To each his own on personal preferences. I admire your aspirations when you initially got your Forester. I had those same feelings with mine, but the word "practical" comes up a lot more every day I get older and when it's wifey's favorite word. Quote:

Thanks man, that really means allot to hear (read) that feedback. That one day at the track was a tuning issue... the throttle freaked out because i was smashing it so hard (first tiem racing it lol) . I havent actually been back to the track since redeaming myself a week after. She ran low 13s with embarassing 60foot times because i had no clue how to launch. Now with the launch control, every launch is consistent for the most part, as long as you let off the clutch properly. Many people have told me that with improvements, this thing would easy run a flat 12, or perhaps faster with a really harsh launch. Its hear-say at this point, so i need to get back to the track and lay down some times.
Monday will be tuning day (I HOPE lol) ... been cancelled twice so far due to weather. Ill go out with lou in the morning and spend the day learning and roadtuning and then spend the afternoon on the dyno, fine tuning the road tunes and going over what i learned, trying each map to see the real-world power differences. To answer jinxsos question, the exhaust is a modified turboXS midpipe, extended 18 inches to fit properly and a direct bolt-on Cobb axleback (3") for the 04XT model year. Its quiet under normal operation and screams on WOT pulls (no resonator, single highflow cat). I also made a bypass for it, which is just a 2.5" tube thats 27 inches long that slides into the muffler and bypasses it.

Life is trully an adventure, this much is true.
With that being said, i come to you again, forester.org with tales of my adventures from true happiness, to heartbreak and back to happiness again. There really is never a dull moment in the life of this forester STi... there really isnt. This will be a good read, i promise you. Pictures and video so you see what i saw, as i saw it. ![]() So today was my tune with lou. I arrived very excited and eager to further my learning about tuning. We drove off to the dyno and lou spent loads of time making tweaks as i drove and explaining everything he did as he did it. we arrived at the dyno: ![]() Get settled on: ![]() ![]() ![]() We do some runs: We make the adjustments: ![]() and we do some more runs: we analyze the charts, make some adjustments. The wobblyness of the line is signature of subarus on the dyno sometimes... the DAM is constantly making fine adjustments to timing and it takes some tedious work to smooth the power curve out perfectly. ![]() So basically, our end result on this heartbreaker mustang Dyno is 315 hp torque. Now frett now, for the mustang dynos are low reading. With the ~18% correction factor to simulate a dynojet... that brings our sum total to 370hp and just shy of ~380trq . Its old numbers were 339hp / 379tq on 23 psi. We achieved these numbers with just 20 psi. Now heres the funny part.... its 20 psi with the wastegate almost maxed out. As it turns out, the Port and Polished TGV deletes and less restrictive exhaust are making the motor more efficient to the point where we are now maxing the turbo out... In other words.. the engine is bringing air in so efficiently and properly now that it doesnt have the ability to build as much pressure in the intake manifold. at 95% WGDC, this is all she will flow with her might 47lbs/min rating. Upon closer inspection and troubleshooting, we were able to back that down to 80% WGDC and still achieve the same boost. It wasnt really making much more after that, so 20-21 PSi was our golden range for the HTA68 on this setup. It allowed for ample and cool(er) air to be going into the motor , which allowed for more timing to be used on the DAM table. Anything above that was blowing hot air into the motor and timing had to be sacraficed. More isnt always better. Nonetheless.... the trip back to the shop was phenomenal! This thing pulls like never before. Just an absurd feeling of force pinning you to the seat, more than it was before on the previous tune. The top end is like a whole new animal. She holds power much more efficiently. ![]() So, you think our evening would end all well and happy there, wouldnt it? Man, if only.... So we get back to the shop and Lou now wants to help me fix a bug with the launch control where it sometimes falls on its face after taking off within the first second. So we take turns taking the drivers seat, with him giving me points on how to properly launch the car. A few attempts in when lou took the wheel to just help me critique a few minor things, he launched from a modest 4800, with what followed an absolutely, blood curdling crunch, screech and a loud BOOM from under the car. ![]() ![]() We both sat there for a few seconds in absolute shock and awe as to what had just happened. I could not and would not want to believe it. SOmething just BLEW up! Put the car in gear, and it wouldnt go anywhere.... so we put the diff in lock and car hobbled back to the shop, where we got it on a lift. At this point, there was a pit the size of texas in my stomach. My poor forester was broken ![]() Teeth came pouring out. Man what a relief! Problem was found. As fate would have it tonight, Lou had a spare matching diff in the shop on the side. Suffice to say, we both looked at each other and knew that it was the only way i was getting home tonight, so we ordered a pizza and got to work. It took us 40 minutes working as a team to get the old rear diff out. We took it apart to inspect the carnage: ![]() ![]() ![]() ![]() ![]() ![]() The launch had sheered the differential gear(s) clean, everything else was untouched. Pizza arrived, we ate, and then installed the new diff. We put everything back togather and took her for a spin. Everything checked out! She lives to see another day again. Lou is the man, he runs a real good show over at Procom Race systems. He took real good care of me and saw to it that i was driving the car home THAT night. It takes a real good business operator to go that kind of distance, and its something that i dont think you see in many shops at all these days. I highly reccomend his services to anyone in central/southern New Jersey. All in all, the car pulled like a demon on the way home. However, i will be abstaining from dry-ground launching until i can get a better rear diff or upgrade to an STi on (means swapping hubs...) . Im looking into Limited slip differentials for the rear, quaiff and cusco being top on the list. All in all, today was one heck of an adventure for this young man. PS : I attribute this diff explosion to the fact that i ran open differential for 6+ months, having all power goto the rear for that time. This is living proof that open diff on a 6spd will eventually breakdown the rear diff. Moral of the story... make sure your DCCD works properly kids!

The correction factor is closer to 12% from a Mustang to a DynoJet, I think you would put down 350-355whp on a dynojet..but who cares about dyno numbers, they mean crap. Track times are a better measure of power. I'd expect traps of 113-115mph with 315whp from a Mustang dyno, which is good for high 11's.
The curves look really good especially the horsepower holding til redline, and the peak numbers are right where I expected them to be. Only issue seems to be the torque is peaking way late. Maybe its because the dyno pull started late, perhaps it spools a little quicker on the street. I'd expect peak torque around 3700 or so. Remember when I said a few months ago about running 23-24psi and that it probably wasn't making any power, just hot air? I'm glad that he is keeping you at 20psi, that is a good spot on pump gas. Post some datalogs up soon! |

@erich, its possible, but to make the STI (r180) rear differential work properly, i would need to swap new hubs and axles in.... have you taken a look at what 04 (5x100) STi hubs cost? (LOL, hard to find, and too much) ... besides, im running large enough brakes as is, in the rear with the H6 LGT swap. On paper, an upgraded differential like a quaife or Cusco inside my R160 would do the trick. The differential teeth are what failed and sheered in this case. I mean, i kinda had it coming. I do often enjoy the fruits of the car so to speak, and i have put it thru the ringer with shenanigans and track events, so within a few seconds of the actual shock of hearing it go boom, that little voice inside my head said... yup... you had it coming! I mean, look at my setup... 9-inch wide wheels with very grippy tires, the drivetrain is fortified with every bushing available to upgrade, stage 1 clutch, locking front diff and a whole boatload of torque at the low end range... it was a recipe for something to snap a weak link in the chain. It just ended up being that a stock rear diff was that weaker link.
@bri : thanks man! Ill get some datalogs up as soon as i get out and do some more highway pulls. Im not sure why the dyno makes it look like its spooling later than it really is, perhaps it wasnt calibrated as it should have been. Also keep in mind i put my stock crankpulley back on, which def made the low end seem a tiny bit sluggish, but at the advantage of having the motor be safe and sound with a harmonic damper. On the street she pulls like a demon and spool-up doesnt seem to be as late as the graph shows it to be, it feels the same as before except with a top end that holds. Kinda feels like going into hyperspace. As far as the boost pressure was concerend, lou and i had a lengthy discussion on that. More isnt always better, period. Plus the turbo wouldnt really build anything past 21psi because for whatever strange reason, the wastegate duty was nearly maxed out to reach around that area. It could have been a bug in the system, but we theorized that the motor was just working THAT much more efficiently with the ported TGV deletes and better exhaust, so much so that it just was taking that much more air in and not letting boost build past a certain point, based on its size limitations. I mean, i dont have a huge turbo, so it didnt come as any surprise. To back our theory up, we were making roughly the same Horsepower as my previous tune of 23-24psi was making, on just 20 to 21 psi. Judging by datalog comparison, it was done on a little less timing advance too, again, which kind of added to our theory of just better overall efficiency. But yeah, the difference is very noticable in the car's driving. She pulls awsome now. However, i will not be doing any (harsh) launching or track events until i get that limited slip put into the rear diff, perhaps lower RPM takeoffs by slipping the clutch. As it looks now, quaife sells an R160 limited slip for about a grand new. Ill have to ponder on this quite a bit because that is a fair chunk of change. Perhaps ill work some extra OT and put it aside as a fund for that. This experience as a whole however, just proves to me that i need a second car as a daily driver. This car reminds me more and more of how it is a weekend warrior.

Sorry to hear about the mishap but I'm glad it's all fixed now. You're lucky he had a spare lying around. Looks like I'll be needing another joy ride soon.
![]() I actually knew about the rear diff going before I read all this thanks to Instagram haha.

I remember Lou tuning a 2012 STI with the same setup as yours basically, and it put down 330whp/325wtq on the same dyno...His setup has dual avcs, and more importantly a FMIC, which I'm attributing to the extra ~25whp it made. The cooler charge from the intercooler over the STI Tmic probably allowed him to run more timing. Just another mod to put in your head to start saving for
Did you guys happen to do a smoke test before tuning? Judging by the high wastegate duties (especially on the Grimmspeed 3port), the dyno showing late spool, and the inability to go over 20-21psi when you were hitting 24psi before the TGV's, there is a strong possibility of a boost leak somewhere. The 3 port solenoids usually run about 30% lower wastegate duty cycles. I don't think the tgv's are that much of a restriction at your power level to make the turbo only hit 20psi now. Not to mention you guys just had open heart surgery on the car by removing the intake manifold to do the tgv's...there's a lot of gaskets there, and add in all the hoses and gaskets on the tmic that came off also. Even if the smoke tester doesn't show any leaks, I would also use a pressure tester at the intake up to 15-20psi to be sure. I'm not saying you def. have a leak somewhere, but its possible. If it was my car, it would bug me, and I'd wanna be sure. Throw some E85 in there for fun/track, gain another 35-50whp, possibly mid 11's car! |

Hey mike, lol thanks and yeah the powers back, ive returned to civilization again.
LOL thanks man, no we didnt test for any leaks, but the wastegate duty cycle is down to 80% now from 95 and still getting the same boost. There may be a bug in the programming, it isnt the first time lou has encountered this, but i will surely give it a leakdown test just to be totall sure of it. The car runs fine otherwise, the spool isnt that late in my opinion. I know the dyno looks funny but lou was hitting the gas an awkward time on each run. Driving it around, it feels pretty normal to me. But like i said, i am going to delve further into this when i get the chance to see if theres a slight leak somewhere. In the meantime, i tried the new rear diff out this evening to see how well it was holding up. Testing out the new Rear differential - YouTube EDIT: If i go front mount, its going to be the same day that the external wastegate and precision (6262?) goes in as well. Go big or go home. First things first... Limited slip (aftermarket) rear differential for hte R160 rear so it dont go boom boom again.
