Ever since the advent of turbocharging in performance automotive applications, there have been those looking to exploit the absolute power-making potential of turbo-based forced induction. We all totally get that as well, because boost is addictive and too much is never enough, right?

Of course, when it comes to this sort of thing and the components used to control, deliver and limit boost pressure, there are good products and not-so-good products, and the right way and wrong way of going about things. Reliable information on the subject can be hard to find though, so we thought it would be a grand idea to demystify the ins and outs of boost control with the help of our friends at Turbosmart in another round of Ask The Expert.

As one of the world’s most respected manufacturers of turbo ancillaries, Turbosmart have a wealth of knowledge when it comes to boost controllers, wastegates and blow-off valves, and the guys in the R&D department want to share it! Maybe you’d like to learn about the performance differences between a manual or electronic boost controller? Perhaps you’d like to know how high quality external wategates and those cheap, random equivalents you see for sale on the internet differ? Or it could be something as simple as finding out what a blow-off valve actually does, and why turbo cars have them?

Whatever your turbo boost control related question, add it in the comments section below and next week we’ll pass them over to Turbosmart who will choose a handful to answer for the follow-up feature.
