My Supercharged Miata Is Already Broken? No Boost

My Supercharged Mazda MX-5 Is Now Slower Than It Was Before

MX-5 Supercharger Install Video - nolocal.info/have/video/roGFqMaw3n6NmJ4
The joy of project cars! After installing the Edelbrock Stage 1 supercharger kit on my 2016 Mazda Miata, the unfortunate news is that things are not working properly. The biggest problem is that at high RPM the car doesn't have any boost with the gas pedal to the floor. We'll examine the installation, data logs, hose routing, throttle body, bypass valve, bypass actuator, and supercharger to figure out what is causing the car to not produce any boost during certain situations.
A big thank you to Edelbrock and Fab9 for working with me on the issues and helping to sort out the car!

    *Important Note:* A lot of folks saying "obviously the car needs to be tuned if you add a supercharger." If you watched the supercharger install video, you'd see the *very first thing I did* was flash the ECU with the supplied calibration file to support the supercharger/boost/etc (the tune). If parts of this video do not seem clear, I'd recommend watching the installation video - nolocal.info/have/video/roGFqMaw3n6NmJ4

    @Sean Grimes good observation but not all manufacturers use that strategy, especially the brand new engines, but i to have seen scan tools display incorrect data, that is one reason i try and only use factory tools, but they are still only displaying processed data, if you want the true picture, a scope is the way to go, using a scope and scan tool together is the best practice

    Hey Jason Proberly one of Your best videos. I totally aggree with Your point about finding the rootcause, is the part we are learning from. I live in Denmark and has a Volvo V70, D5 185 hp, my 2007, manual 6 gear, driving over 20 km/l (norm 14.8) over a distance around 200k km. It is now “driven in”, with 420k km on the clock. So I think a lot about effiency and how Long things can last. I also like Your videos with better effiency, whether it is electric, gasoline, diesel or combinations. I liked the video with mix of gasoline and diesel and high effiency. And also Your remark about mileage mostly is about, how hard You press the pedal. It is so true. We can easy cut consumption to driving by 10% to 20% by driving more relaxed. All parts have reduced wear, by driving more relaxed. It could be fun to know what have greates particle polution, at newer diesel/gasoline driving relaxed, or a electric f.ex. Tesla driven faster. Or are electric cars driven more relaxed? I think of total particle pollution from tires, brankes, enginge etc. That said, Tesla have done a lot of great innovations.. but many things could as well have been implemented in carbon engine verhicles. Best Regards Brian, Denmark

    Really good videos on the MX5! just one thing you either talk too loud or have a microphone gain too high. Even at a low volume setting its sadly a bit painful to listen. Example when you talk at 02:13 to 02:15 this is the right voice volume you should talk at; Hope this helps.

    Awesome video, I really like the closing comments about the attitude video creators should have. If you have a moment, what is the program you use to capture all the data, and did you buy the cable separately? Another: I was wondering if the reason it could be fixed by tuning is because the throttle position is entirely computer controlled or how did you know that the throttle butterfly was not malfunctioning or getting stuck? Thanks. Nice S2K on your other recent videos.

    I couldn't understand WTF you were talking about for the first half of the video and I know a bit about auto engineering. I figured I was too far behind the times. Then when you said you didn't understand how the bypass valve worked (!) I realised I didn't understand the first half because you were talking gibberish! How could an "engineer" get this simple principle so very wrong? Bypass valves work like turbo blow-off valves or wastegates - they dump excess boost when it's not needed. Simples. Also you keep talking about :tuning problems". You didn't have any tuning problems you had software or calibration problems.

    On the last video it was mentioned that horsepower is heavy. So having a lighter car with less power is not only more efficient, but just as enjoyable for street driving. It is called a Z06 C6 Corvette. Lingenfelter can pump out 650 NA horsepower out of an LS7 motor. This Vette, the Z06 weights just 3140 pounds. Horsepower in this illustration is not as heavy as thought. Plus, you can get one for a reasonable price nowadays.

    From watching channels that do custom tun es, I've learned you should data log and send the results back to the tuner.This helps improve the tune and spot wierd issues. In your case your had a glaring problem. But this is a learning moment and I hope this helped others out.

    Our owners club has one of the UKs MX5 top mechanics who trains Mazda mechanics he has been involved with the MX5 in the UK since the NA. His advice if you play with them don’t expect the reliability to last as their engines are at optimum balance between performance and longevity. Although a simple task like re chipping with a BBR set will increase performance by several percent but it won’t last. If you want performance don’t by an MX5 get an Aerial Atom.

    Thank you for going through the diagnostic issue to the end. This is what I do for a living and some people think it's magic or the mechanic is automatically supposed to know what is wrong as soon as they tell you the issue, give you the "Code" or hand you the keys. Very clearly described step by step and no bs results. Sometimes as a mechanic I will be watching one of these videos and say "Hey wait! That's not right!". And some guys end with results like "It is what it is". But this was clearly diagnosed and you used all the tools available to you and one of the best tools is not being to proud to ask questions. Questions always trigger a new thought pattern even if the answer you get wasn't correct. I don't remember when I subscribed to your channel but I haven't seen one, I didn't like. Keep doing it just the way your doing it and thank you again.

    Jason, don't throttle-by-wire SUCK? I mean, it gives a totally synthetic feeling, wich ruins the driving experience. As a driving enthusiast, I don't want a computer controling my acelleration choices, I just want the throttle to do what I I'm telling it to. Also it's a very delicate system with lots of sensors and actuators, wich makes it much more susceptible to fails and makes maintenece more expensive too. So, my question is, why don't we have the option to buy a new car with cable throttle anymore? And, of couse, don't throttle-by-wire SUCK? Would you do a video about that? Greetings from Brazil.

    You baffle me with your car modding decisions. Superchargers, even positive displacement superchargers, are kind of pointless on the miata at any boost level. I make 7 psi @ 2800 rpm and 10 psi @ 3200 rpm on a single scroll Borg Warner EFR 6758, and I've got a twin scroll housing that should deliver that same boost 500 rpm earlier. If you are driving a manual miata, you are rarely below 2000 rpm based on the owners manual recommended shift points. You could be making 7 pounds of boost on a cheaper, smaller, and lighter Garrett turbo as low as 2000 rpm if you set it up right, which completely neglects the one advantage a positive displacement supercharger theoretically has over a turbocharger.

    If you had taken it to a good dyno the operator would have seen the difference in the throttle position and then been able to calibrate the TPS as well as gone over the fuel mapping at any throttle increments they feel need to be mapped. As for the bypass valve being a restriction.. It would never be a restriction as its just bleeding air past the impellers. The dyno would have been the simplest diagnostic tool and saved you a lot of time.
