The only undisputed fact is that you have a high-mileage car. That, in and of itself, does not make you an expert in any way, shape, or form. You're quick to call everyone else an idiot and try to force people to respect things you say but then repeatedly say things that are blatantly wrong and don't live up to the expectations that you're demanding of everyone else. That said a lot, but not in a good way.
Anyone with any experience at all knows that dynamometers all require a baseline in order to quantify delta gains. They all know that dynos read differently, and they all know that results can be skewed-intentionally or accidentally-and that they're not comparable unless you are literally strapping the cars to the same dyno at similar times on the same day with the same operator.
Very few people did a baseline dyno on their stock car before throwing on their turbo in order to quantify the delta. Even fewer are going to have the same supporting modifications to make the dyno comparable to turbo-only. Hell, even you don't have a baseline that can qualify anything other than running results.
You don't have to listen to what the experienced users have to say but the least you can do is stop being a hypocrite and follow your own advice. You've spent a lot on your car now, just take all of your mods off and get a baseline, then come back with your delta after your X-37 install.
I actually don't care if you respect anything I say or not. I am offering up an opinion. People can choose to take what I say with whatever grain of salt they choose. I buy something, I try something, I report something. And driving 165K miles on a car, almost living in the car everyday and doing it in less than 3 years makes me an expert on how the car handles stock, and how it has responded with what I have done to it. That is a lot of seat of pants or butt feel. So much that I can tell you how different the car feels on a high or low barometer day, how the stock suspension reacts over smooth versus rough terrain, how it accelerates, brakes, corners, shifts, and high speed reverse more so than anyone here. I am wiling to cave on the baseline and using my tune 2 as my baseline, even though anyone with any intelligence can look at it, and say, no one has those numbers stock from FORD FIESTA ST. NO ONE. Therefore, something I installed made the increase, and since the most intelligent thing would be the exhaust because it is a turbo car, I am willing to go with that.
Now, for the other thing you mentioned, why only 4 turbos. Because I did my research on this and the other ST forums amongst other car forums on the turbos in question. Before I say this, I want to follow up on the cyborg. I think Bryan makes a fantastic product. I think Bryan is very knowledgeable and have zero problem trusting anything he says. Even if Bryan was not rebuilding these turbos himself, which I believe he is, he knows enough about it to delegate to a company to get it done for him and that is good enough for me. I have manufactured clutches for the high performance world, so I get it. I am different in that I don't like hearing my car. When you are into audio, any noise other than the sound of music is annoying and in the way. So keeping the car as quiet as possible is job 1. Goal was to make as much power as possible as quietly as possible without having to mess with the fuel system or engine. I have been there, done that, and it gets really freaking expensive, and reliability goes down the drain and then it gets so sensitive your constantly having to mess with it. Could not afford to do that with my job. I needed reliable transportation. Adam offered up the Cyborg, and X-37. It was ultimately my choice, but the X-37 offered a solution with less modification and quicker turn around time. Between the Cyborg, and X-37 we are probably splitting hairs in the grand scheme, and should the X-37 with adam's tune make more HP or less HP than the Cyborg, it changes nothing in regards to my respect of Bryan and his product and what he has achieved and what the future holds for him and his product. He is a one man show, and he cannot mass produce what he's doing at the moment, but as his business grows which I am sure it will, he will get there. Anytime anyone ask me what turbo would I recommend, I say, based on what I have read, the cyborg deserves a very serious look. I say it all the time. Price vs performance. It is an incredible deal. If you can afford to wait and send him your turbo first, it is a stupid good deal based on what you get.
The four turbos chosen, we not necessarily the only options, but based on my extensive experience putting High Horsepower engines in dinky small cars, There is only so much metal, and the chassis is only going to take so much. A buddy of mine out of Michigan dropped a LSX 900hp motor in a solstice. he talked about it going sideways up the highway. You can do it all day, doesn't mean its safe, and doesn't mean it is reliable. He knew it when he did it. So, I really believe, now note, that word implies opinion and I can only offer an opinion based on my experience. You produce a fiesta st making 350WHP and 350 FT TORQUE from what a dyno would say, and they have over 50,000 miles on it, that would become the proof that it works and works reliably for daily driving. TORQUE puts an enormous amount of stress on a chassis. Nope, I have no data to back that up other than the National Safety and Transportation Board, or Indy, or IRL, or Nascar. You add support braces to do what???...Class???? Add support, that's right, very good. Its called reinforcement. So either it adds benefit or we have another cobb in your opinion, selling unneeded product.
So as I said to tWolf, those who would want to upgrade their vehicle but not go to the outer extremes as say, Rick, or Rodmoe, or I even think Hijinx has like a 2867 which is high up on the food chain, He drives It every day, but how far, how long, how hard, (no need for him to chime in), If he is racing, more stress on the body, after 30,000 miles of that kind of stress, lets put his car on a frame alignment machine, and see If it is still in spec. If it is, then he has proven his point that the body can handle it. Though not sure hes making all that much power anyway. I though I read something about he said 240 or so. Not sure. Even under stock conditions, after a long period of time, the chassis can weaken due to metal fatigue, Im sure you know that, you're a smart guy.
These 4 turbos, don't go to the extremes under normal tuning. They offer a lot of fun for not a lot of money. Each one offers their own benefit. The pumaspeed X-37 may offer a small advantage over the cyborg if nothing more than time in use. They have been working on this car for a long time. I could be wrong there. Not trying to start anything. ATP offers huge advantages because of experience, but the boost maps, seem to move the 2554 and 2560 out of what I called useable driving range. I called it. That is my assumption. Don't get your panties in a wad. If you live on the street, with traffic, your usable power band is between 750 rpm and 4 K is probably the upper limit. Short quick shifts. The other thing these turbos do is move off the instant torque just enough by moving the RPM band, so that it reduces stress on the transmission, and clutch, and offers a little better traction so the car can get moving. Once your moving, the stress on the tranny and clutch diminishes exponentially.
Rodmoe, and Rick, Joe at 2J, Russ at DHM, Adam at Tune +, Bryan at Cyborg, Pierce Motorsports, and now the guy who posted the 4 turbo setup, OMG that was awesome, anyway, very experienced guys and I would be so lucky to know and have done what they have done. Would trust what they had to say any day of the week. Hell if Rick said, I just installed a springy thing, and it made 20hp based on my butt feel. I would want to know where I could buy it. No dyno needed. He butt feel is probably more accurate than the virtual dyno. No I am not a Rick worshiper. I just respect the guy and understand him. Were both of the anal type when it comes to getting stuff done in our cars. I will, just like him and have just like him go to some stupid extremes to make something work in a car. So I get him. Completely. Joe, races his car, on a regular basis. While I did not completely agree with how he handled my brake situation, I have purchased 3 sets of pads from him since. I could have gotten them from Summit or Jegs or Wilwood, but I trust what he has to say. Russ is on the bleeding edge of what can be done power wise on this car in the states. He knows what hes doing. Rodmoe, is along for that ride. God Bless him, lots of experience in his car, with lots of power. He knows. Pierce is a suspension guy. He knows. There are so many others here, but the point you made was I don't pay any attention to the experts, and that is not so. I don't want to be an expert. I am just sharing experiences. It is up to those who read to come to their own conclusions. Anything I post on any matter other than audio, is an opinion based on experience. My experience. Everyone has to come to their own conclusions but in joining this forum, I am doing everyone other than you and hijinx, and a couple others a disservice if I don't share my experiences not experience(I want to clarify) other than with audio. I can be harsh sometimes, but look at who I'm dealing with.
