Hello everybody, My name is John and I'm a new member of MNSubaru.com. I go to MSU for Automotive Engineering and have lived here in Mankato for a little over a year. I moved to Minnesota last March from Virginia Beach to pursue my degree and be closer to my family. Living in Virginia I was used to having the boxster rumble almost everywhere I go so I've been kinda bummed living here where there are very few Subies and even less subaru enthusiasts. It's been a great relief finding MnSubaru and hearing about some of the events and discussion that take place close to home. I was referred here by the guys at Grimmspeed Performance in Minneapolis. I was there dropping off an exhuast manifold and when I asked about local Subie events, meets and such, they quickly referred me to this forum. So here I am! I have been the proud owner of 3 subarus. Over the years I have become a Die-Hard subaru owner and my experiences with these vehicles is actually what inspired me to pursue my current major. Currently I have a 05 Sti and an 08 Legacy. My Sti is my pride and joy, I've had it since July 2004 and not a day goes buy where I'd consider going any other direction with my vehicle obsession. It's currently under construction and the motor should be back to me by mid June. Once she's back on the road I look forward to joining in and hopefully organizing some events with you guys. Thanks to everyone who contributes to this forum. Now maybe I can talk to someone besides my fiance and coworkers about turbos and tuning maps. They're great but I know they're just pretending to be interested.
Welcome! You can always wee what we're doing in Rochester here: http://mnsubaru.com/forums/showthread.php/7562-Rochester-S.E.-MN
Mankato is pretty thin in the Subaru market. Plus, the car scene just up and died last year. Some people gather in the free lot once in a while though. Don't let Gary Mead tell you mild steel is stronger than chromoly.
Thanks for the welcome everybody. Just spoke to my builder in California and he informed me that my engine will be shipping out tomorrow so I should see it some time next week. My car's been down since November so I can't begin to tell you how stoked I am to wrap up this project and get the car back on the streets. It wont be quite the monster I anticipated at first. I have to break the motor in on pump fuel before switching over to E85, I'm not sweating it though, I'll just be happy to drive the car again. If anybody is interested in getting their hands dirty, learning a thing or two about subies or just hanging out and having some beers in the garage with a bunch of gear heads, let me know. I'm going to start a separate thread for my build and keep updates there.
Yes, I know Lucas. I was pretty jealous when he told me he had two Sti engines in his garage. How's your car coming along?
Well, I actually live in Kato right now. If you see the San Remo red 04' around town, that would be me! I'm pretty easy to spot. I don't go to MSU anymore, but I still lift at the Otto Rec center. I'd always be down to chat or help you with anything, but being in the AET program means you probably know a hell of a lot more than me.
welcome!! I live in Le Sueur only drive mine on the weekends. I am in mankato at least one time a week. There is nothing within 12-20 miles from me... Welcome
I've said it before too to others, if you need a hand down there, give me a shout. I typically live down there. haha welcome aboard, you'll find more of us down in Kato once school is in swing
Welcome. What's done to your engine if not a secret? The last time I sent my engine to CA was to get it sleeved
Ha ha, no top secret build just your regular built BIG turbo Suby. I wont go into a lot of detail but the major mods I have done are as follows: Cosworth 9.2:1 CR Forged Pistons 99.75mm Cosworth 278/274 AVCS Cams Eagle H-Beam rods Supertech 1mm oversized valves, Inconel exhaust valves Supertech Dual valve springs, retainers, etc. Garage Tuning custom head work (radius porting) JDM 12mm Oil Pump Killer B oil pickup I think that's about it for the engine. I have an extensive list of supporting mods that go with it though! I Shoud be Getting my Hydra back from Quantum Performance next week so I'll finally be able to fire up this beast. Oil pump is already primed! Probably see some of you guys at some upcoming meets, dying to get this car back on the road.
The setup itself is capable of upwards of 700whp. My ACT clutch might let me hold about 600whp but it's the massive torque from running E85 that's probably gonna shut me down before that. My original goal was for 500-550Whp but I lost my mind halfway through the process and more than doubled my build expenses. I was warned this would happen. LOL!!!
I still do not see a specific turbo listed. A turbo that is capable of 700 whp is not going to spool fast enough to be a torque "monster", E85 or not.
Do you know this from experience or is that just the impression you gained from reading subaru forums? BTW; torque is the measure of rotational force not the feeling you get in the seat of your pants when your turbo spools up.
Torque is actually a moment and power is work done over time. As far as torque measured with large turbos go, it is a simple matter of force applied vs. a given rpm. Large turbos simply do not provide the pressure ratios at a given rpm that would measure a higher torque number. It's pretty simple. From my experience, knowledge, and observation, large torque numbers are only going to happen if you can produce a high pressure ratio with your compressor at a relatively low rpm. E85 allows people with small turbos to run large amounts of boost at really low rpm, thus producing high torque numbers. If you cannot make high boost pressures at low rpm (below 4500 rpm), you simply are not going to produce large torque numbers. The people within this community have not made large torque numbers with turbos capable of 700 whp on E85 or race gas. There are exceptions to the rule, but those exceptions are not using a fixed geometry turbine or a turbo mounted in the engine bay. Torque converters help too.
I will agree with you that a small displacement motor has a hard time making significant low end torque on a big turbo setup. That's generally speaking of course. I'm not talking about a stock 2.0L WRX with a GT35R. On that you probably wont see full boost until about 5500 rpms. A 2.5L Sti on the same setup is gonna spool a little quicker, maybe 4500rpm's depending on the compressor size. Now consider a more advanced setup with proper tuning, larger cams, twin scroll turbo, higher compression pistons, lots of head work and of course good old corn booze. You can make big numbers across a much wider power range. You can disagree with me all you want but try telling those that have done it that you can't make a lot of torque on a big turbo. AJ of Adrenalin Rush in Woodbury is making 701whp/ 555wtq on his 2.7L WRX running E85. He has a GIGANTIC turbo! Phil at Element Tuning has probably tuned hundreds of 500+WHP subarus that make big numbers across a broad power range. One of his recent customers made 667whp and 577wtq on the almost identical setup as mine. He started making boost at around 3000 rpm's and at 4500rpm's he was making 450wtq. A stock sti makes about 220wtq on the same dyno. You should call Phil up and spit some of your schoolboy knowledge to him, be sure and let us know the type of tongue lashing he gives you. He'll probably tell you to stick to what you know, which seems to be the basics. Keep plugging away and eventually you're brain will catch up with your mouth.
You'd be well served by shutting your own mouth and maybe re-reading Piddsters post. He wasn't ripping on you, merely stating his own observations based on what he's seen within the community. You may want to read some other posts of his, he's one of the more knowledgeable guys on the board when it comes to making power out of a Subaru plant. He's also one of the better fabricators and all around hands on guys here. Instead of waving your E-wang around trying to prove him wrong, you may want to ask what he means by "high" torque. His definition and yours may be different. Start reading some more and insulting less.
Whoa, whoa, whoa. What seemed to start off as a good discussion in your reply turned into a serious chastising. Professionalism is a trait that carries people places, as opposed to rudeness. This fact is especially true when one is new to an organization. In the real world that kind of attitude will get you fired in short order. Brian may have hit the nail on the head with our definition of high torque, but I'll digress for the sake of it. Anyways, back on topic. I would love to be proved wrong. If you do it, that would be fantastic. If a broader powerband with large turbos can be successfully obtained in the Subaru community, more power to it. I'm not against that prospect at all. However, I have yet to see it happen without a torque converter or a variable nozzle turbine. You referenced AJ's car. Great. He did not make "massive" torque which you eluded to in your previous posts. Yes he made great power. It was not on E85. Read a little closer. Yes it is a monster. It does not have a typical setup nor does it follow any rules most of us play by. Apples to oranges, playa. I've seen more of AJ's setup except for four other people on this forum. Does that make me awesome? Not in the least. Stop preaching to the choir. Also, please stop with the references to what Phil does, and what a stock STi makes on various dynamometers. You seem to think that I have just gotten into the game of modifying Subarus. I'm well aware of what these cars put to the rollers. I have also met Phil in person, and have seen his style of operation. He is a great tuner. He is also not a mechanical person. Do not argue this with me. He does not know the Hydra as well as you think he does. Again, do some homework. I find it funny that you are in your first semester in the AET program, yet you are suddenly an expert in modifying Subarus. I'll check with the 30 graduates I know from that program and see where you line up. Lets see. Can you tune your own car? Doesn't look like it. -20 points for you. Do you have to pass me on to other experienced people to verify your claims? -10 ten points. Have you posted the turbo you are using? -15 points. Can you verify your boost response with a compressor map? Not proven yet, so -10 points. Have you posted your "supporting" mods? -15 points. From the looks of things, you have a long ways to go before you gain respect in this community. Oh. And since you're in Kato, beat Whener for me. Will you?
Can't we all just get along without bench measuring each others "e-wangs". Besides the proper way to solve this would be down the strip. Cornfed_sti vs. Piddster
I shouldn't have responded at all. This thread pretty much cements why I spend very little time on forums anymore.
