Nameless Performance

Let me clear this up after talking with English about this. They found out that the factory actuator does not have enough physical throw in the rod to fully open the flapper valve. It has nothing to do with the downpipe or any downpipe for that matter. They are only seeing it open about 30% English Racing "The actuator doesnt have enough throw to allow the wastegate flapper to open 100% it opens maybe 30%" "the DP has no affect one way or the other if anything I think this is using a modified form of the Ford boost control strategy to open the blow off valve or engineer controlled boost leaks to limit the problem no matter what its obvious that they engineered one mistake to fix another" They are about to get going on Ellesedil car now.

Alright! Well here is what we have found out. Ryans Original setup with the Old DP and our full catback on a stock BPV had no overboost issues. Target boost was around 17-18 which is basically all the stock BPV will want to hold. Since then Ryan added a new BPV which is ours. We then re testing the Old DP and our full catback with the new BPV. It over shot the target boost we originally had on the tune that was done on the car with the stock BPV. Aaron the tuner from English racing said that was due to the stock valve leaking and our new valve doesn't leak so it will hold more boost. It hit 20.74 PSI We didn't change a thing in the tune just rolled it right off the dyno and into the shop to swap the old DP to the new DP. Install was a breeze and took them about an hour and a half. There were no install issues and no flapper issue. Got the car back on the dyno and did a pull. So the new DP and our full catback with our BPV. Did almost exactly the same as it did with the old DP. The new DP had a slightly better spool up time and made more power and TQ across the entire board. Since the car seemed to really want to be in the 20's for boost we changed target boost to 20PSI instead of the 17-18 it orginally had and the car made 299.81AWHP and 352.72TQ aka rocket ship. Aaron did some more massaging in the tune and got the car up to 300.69AWHP and 365.19FTlbs TQ After talking with Aaron about everything he said that having an after market BPV on the car you wont be able to get lower boost numbers. Having a valve that will hold the boost will net you 20+PSI. If you wanted say lower boost like 16-19PSI you would need to keep your stock valve. We also talked about how having an after market valve then porting the housing some since the stock port for the waste gate cant flow enough to keep up you could essential keep the aftermarket valve and still hit a lower boost target with porting. In conclusion both the old DP and the new DP behave almost exactly the same except the new DP overall has better performance netting you in more power and a quicker spool time. Attached is the dyno/boost graph. In RED is the Old DP with our valve. In Blue is the New DP and our valve. http://i64.tinypic.com/15d8cyc.jpg

Will have some news for you guys later today when I get back in the office and have the logs. I must say these motors can make some POWER!

As Ryan already announced we will be at English Thursday doing some back to back tests with the down pipe. We have had some stupid crazy weather here that has put this on the back burner(tons of snow which is normal) and also English now finally can save the logs so we can actually show you data when we do the test. Basic game plan. Ryan will drop his car off and it goes straight on the dyno. Do a few pulls then log. Pull the car off get it on a lift and swap the down pipe to the new one then right back onto the dyno for more pulls. Record those logs then compare the two and graph them together then show and tell. So stay tuned boys!

Shoot me an email Steven.R@namelessperformance.com Lets discuss some dates and get this moving!

I was basing my findings off of what I read on page 12 I believe. You also stated on there you were actually under boosting sometimes and that when it got colder in out side air temps it would hit 22psi sometimes. When the air gets colder any car with have in increase in boost. Its Science like I already explained.

Guys I want to make this simple. I feel like im beating a dead horse here. Help me HELP you! I've spent all day gathering logs and speaking with tuners for you to get this sorted. All day reading this forum and other forums about similar issues on these cars. Im doing my home work. Im not here to argue with you. Just doing my research to find the facts not stories so again if you have not installed this on your car in fear of it overboosted please do not chime in right now. We just want to hear from people who have the first hand experience please. PS. Sorry if im posting to much in a single day not sure if their are rules on that in this forum but im devoting almost all my time to this so it can be resolved quickly. We are all ready to get this over with as much as you.

Exactly why I'm here trying to gather as much data as possible. So we can come to a resolution on this! No where did we say there couldn't be an issue here but from our perspective there have been more successful installs than failures.

This is exactly my point you are basing you thoughts on someone else who had an issue. When there have been others on this forum who have not had the issue. You are not doing any testing for us as there are multiple cars out there with this same DP right now running around enjoying it.

Did you install ours and have an over boost issue like you had with the Indvida? If so can you please provide me with logs.

Again there have been multiple people who have installed this with a correct tune and not have had an over boost issue. Simple facts stated by you guys in this forum.

OK I understand that argument by visually looking at the two parts side by side. One looking slightly different still doesn't prove one is superior over the other and still doesn't explain the 5 other people with the group by part that didn't port it and didn't have over boost. This is why I continue to stress its a tuning related issue.

OK then why is no one doing those same fixes like porting the wastegate to combat the already known issue with these cars overboosting?

Just spoke with one of the owners about you since you are local. We want you to go and do the normal install then take it straight to English racing for the tune by Aaron. If there are any issues after the tune about the issues you guys are talking about here on the forums we will then take over your car and do what is necessary to figure it out. Let me know your thoughts.

Has anyone had a chance to read this forum post? http://legacygt.com/forums/showthread.php/overboosting-issue-catless-downpipe-236467.html Some already published information about these cars and how they overboost with how the factory turbine housing is designed. I just read all of this again. So far from reading every comment ive made a list. This is my list of people who ran our DP with out issue: Fischbache Swannee Dreizehn Sarang FlLegacy laopadak People with issues Eckselven. Over bossted on his TBE with fitment issue. Got the fitment issues resolved then took the CBE off reverted to stock and have no overboost issue until you installed a Cobb intake. Was your car re tuned for that intake or did you just slap it on? Do you have logs you can send? Sm00veM00ve had a cracked housing that was ported, something weird going on with his 20g. Went back to stock and had overboost issue then after being fully tuned and having your tuner tinker with it he got it pretty solid but you still noticed overboost during colder temps? Do you have logs you can send me and also who is your "tuner"? Haruichi808 Had overboost issues, You also stated you had amateur hour on the dyno and had hose's flying off your car and you may have the EBC hooked up incorrectly. Im sorry but its hard for me to pin point an issue to any part on your car if it doesn't sound like its put together correctly or well. Would advise a professional to do a solid once over on your car. Then I see you installed an Indvida DP and still overboost but its not as much as you saw on ours but its "acceptable" ApexoftheVortex Had no issues with boost creep. Then sounds like with any fast car you got used to the power and wanted more as do we all! Got a different tune from a totally different tuner then had boost creep issues. Now the finger is pointed at the DP when before on a different tune it was a non issue? Is there more I didn't see or am missing? Just trying to get all our ducks in a row here. Also having colder temps will affect any turbo charged car, or turbo/ supercharged anything for that matter. When the temps drop the air condenses thus providing more boost. The hotter the air is the more it will expand and not have as much boost. Same theory a Steam Turbine power plant does. During the Winter months it runs at half capacity but will still produce the same amount the plant does during the summer at full capacity. Mike from TA who has tuned from what we see two of these dropped some solid info as well "Report Post Send a private message to Tuning Alliance Find all posts by Tuning Alliance Reply With Quote Multi-Quote This Message Thanks Quick reply to this message Hey guys, I have tuned a few of these recently and have seen varying results. I was asked by some customers to comment and thought this may be helpful to others. I haven't had much up and close time with a VF54 personally, but its seems the wastegate sizing is a bit too small for the system.I would speculate that variation in the turbine castings is causing some to flow better than others and ultimately work okay while others consistently creep. I have seen the same issue in 15-16 STi's, when a high flowing downpipe is installed severe boost spikes occur (23-24psi) regardless of boost control or flapper position. In extreme cases I have implemented throttle limiting to decrease airflow and boost into the engine. This is the only easy fix aside from reverting to a stock downpipe. Problem: Insufficient Wastegate flow (mechanical boost creep) Cause: High flowing downpipe Potential Fixes: -Wastegate and/or turbine porting (requires turbo removal) -External Wastegate (Not practical on 5th gen) -Electronic limiting of throttle -Restrictive/stock downpipe Other suggestions: -FMIC (may reduce boost and reduce charge temps for a happier engine) ~Mike" Again talking about how these turbos need porting and the waste gate size is small and when you take that and an extremely free flowing downpipe boost spikes occur. Talking about different elevation and different climates is all in the tune. This is not new knowledge. Your tuner that is from that area will tune the car to the climate and what the car needs to live. When we go to races that are all over the US we have to constantly change the cars tune depending on where we are at. You can't expect to be tuned say where we are from in a colder wet climate then when we go to a race in Florida were its super hot and humid the car will perform the exact same. It doesn't and adjustments need to be made. So far from the very few logs I've seen and had to go out of my way to find or get they are all drastically different from one and another. We ask who tuned your car for a reason. Being in this industry and talking to hundreds of customers on the daily I hear tons of horror story's about this sick deal this guy got on an e tune and then his cars blows up. Come to find out its Joe Shmo tuning cars out of his mom's basement. There is a small number of tuners I know and trust nation wide. Then there are hundreds more I would never trust since they simply dont have the knowledge or experience. Maybe they can do basic tunes on a wrx/sti fine but not on these Legacy's. They are complicated cars to tune as you have found out.

Just sent them an email!

Gentlemen, First off we want to start by saying that we are not trying to ignore you or leave you out in the cold. We had gotten locked out of this account and have now been able to regain access. So far after re reading every single page and yes we have been reading this every week. We have seen 2-3 people install these without issue and with a solid tune from a reputable tuner who knows what they are doing and they do not have any issues. We also have Ryan's car which has been running for a few years with our downpipe and has not had any issues with over boost. He had it tuned at English Racing. On a side note we ask that you not bombard him with questions as he is just trying to be helpful in the situation. There has been a handful of people who said they have had issues but only one of them provided any solid data on it. Then it seemed this person and his tuner sorted it out then installed an intake and was back to over boosting? Then we have everyone else who hasn't touched the down pipe complaining it over boost. Well how do you know it does? Have you tried it or are you just reading a story someone had on the forums? To the people who have tried it and said they had issues. Where are your logs proving that so we can look? What other supporting mods do you have on the car to control boost? We use and recommend the Grim Speed 3 port controller. We use it on all of our race cars here at the shop and never have issues with them. Keep in mind this downpipe is very complicated to make. If a properly made downpipe is installed on this car it will out flow your factory waste gate the second you get on the gas. This is why you need the correct supporting mods and a tuner who knows how to properly adjust the waste gate duty cycle to make it all work correctly. We have been in contact with English about this and will be posting the information gathered from Ryan's logs. Currently English's tuner Aaron is having laptop issues and can not record and save data logs. This is part of the reason why we have been unable to get Ryan's car on the dyno to gather supporting data. We are all trying to organize times to meet up and get the car into testing but it can be very difficult with 3 parties who all have conflicting schedules. We are going to come to a conclusion on this. We want you to be happy with this. This is why we do things like group buys to help customers who have rare cars like you guys. Please understand from our perspective that only 3 of you installed this DP and had no issues. Ryan's car has been running one for years with no issues and then a handful of you came forward suggesting you had experienced over boosting and only one person had supporting evidence there was over boost. From a business stand point the fact that we only have proof of one issue does not make us eager to refund every order, while we have people that are driving their cars right now with our downpipe installed without issues. We hope you understand our point of view. Like we have explained before, we are not the type of business that ignores theses types of issues. On the other hand we will not just state that we have 3 out there that are working fine, so if you haven't tried it sorry about your luck. We want to help in this process and are doing the best we can with the time and resources we have available. We are in the process now of getting the information together to help those who claim over boost is an issue. Our companies activities are taking a large portion of our combined time as we are still relatively small, however we are prioritizing this issue and doing what is within our abilities to take action and find a solution. This will take time and we appreciate your understanding in this. Our racing programs have been growing very quickly, as we are sure some of you have seen on our social media accounts. This takes up a ton of our time and resources. John one of the owners and lead engineers is head of all the racing so he is constantly gone flying all over the US managing race events and ensuring success on all fronts of our racing division. The other owner Jason just had a baby! So he has been very busy doing that. We tell you guys this information because we are a small company, filled with a handful of people just like you, who wants for our customer base to know us more on a personal level and can take pride investing in a product that supports small business as well as some of the best build quality and performance characteristics on the market. Regardless, we are busy and so are you, we understand that and hope that you can work with us on the issues that have been brought forward. If we truly want to get to the bottom of this please provide us with information from your vehicles so we can analyze the data and address the issue. For those of you who have installed this part reaching out to us with the information would be greatly appreciated. * Provide us with data logs * List of supporting mods * Who tuned it *List of other mods you have on the car This will help us immensely in figuring out the issue, we are reaching out to you for your assistance in this matter. To the guys who have read this forum and not installed it in a fear that your car will over boost. Please sit tight and let the people who have actually tried it get to the bottom of it. Your input does not help with this matter. . Also to anyone who private messaged this account. We just got all of those when we unlocked this account. We promise we were not ignoring you. Please take note that emailing us is the best form of contact as it will notify us immediately. Lets all be professional and figure this thing out! In the mean time we are working with English Racing and Ryan to get a time to do a dyno pull with his car's current setup. Then swap just the DP and touch nothing else then do another pull then plot the two graphs together. The communities response and the way this was handled has been a huge eye opener for us.
