Turbocharger episode
This episode of Podcast Auto is about turbochargers. They can be a heavy subject, so I'm not sure if the show will answer your every question, but hopefully you'll learn something new.

I've also started a Flickr account for pictures. The first batch is from the autocross event I covered last show. Check them out if you are interested.

    Your podcast on turbochargers was great. In fact all your podcasts have been great so far!

    Question: How are superchargers different from turbochargers? Are they different names for the same thing?

    thanks,

    JJ

    Thanks for the compliment, I'm glad you are finding the podcasts enjoyable.


    Superchargers and turbochargers both perform the same function, namely compressing air going into the engine so more fuel can be added and more power produced. The difference is that turbos get their energy from the exhaust of the engine, while superchargers are directly driven by the engine typically by a belt. It gets complicated when you start talking about the pros and cons of each, but that is the main difference. I'll have to do a supercharger show in the future and talk about it in more detail.

    Hi,
    Your shows have been great so far. My wife and I are in Israel now, and it is great to be able to listen to you on my iRiver as I walk the streets of Jerusalem. I find your shows very informative and entertaining. I'm wondering if you can do a show on Supercharged engines, the pros and cons of turbos as opposed to superchargers.

    How does your M3 copare to a WRX?

    Thank you,

    EC

    hi jerry, i enjoy your shows and it's very entertaining... but in this episode, something that bugs me a bit is that your flawed explaination about antilag...

    it's not fuel dump, it's because that it's common practice to run richer fuel/air mixture... and so there are more unburn fuel in the exhaust, so basically, they can open up a vent and allow air to pass into the high pressure, high tempereature area of the exhaust before the turbine, and so cause combustion which turns the turbine more. or as i do it on my impreza... i hooked the BOV up to the exhaust.

    btw, i am only 16 turning 17 ;)
