Designing a Twin Charger System

[cammmy]

Hi Everyone

I've been reading the excellent threads on this forum regarding twin charging engines. I was wondering if it would be possible to create a general design thread to give people (like myself) who are looking into to doing something like this some guidelines on how to plan their system? Of course that is only if those in the know have time.

Would anyone be able to give a basic overview of twin charger design/s (with positives and negatives of having TC>SC or SC/TC?). Components required and their placement/plumbing, sizing the compressors involved and maybe adding diagrams and any issues that you have come across?

I've spent a while searching for information and have found some good stuff (mostly in this forum) but it's a bit scattered between a few different threads. It would be really good to have a thread that laid out the basics all in one place as opposed to looking at specific builds. Hopefully that could cut down repetitive questions in the future also; People could start their own specific design/build threads after getting the basics here.

Thanks
Cam

Your post hints a little at a diy build possibly more suited to a motoring forum, or perhaps the hobbies forum.

I suggest you Google ''VW's Twincharger System Overview'' as it should bring up a few main points.

As you mention, searching on here will bring up a lot of info too,

Brian,

Hi Brian

Thanks for the reply. The threads I have read so far were all in this section, which is why I've posted here. If I'm incorrect, can this be moved?

I've had a look at the VW twin charger diagrams however it is different from the system that Warpspeed talks about in that it disengages and bypasses the charger at high RPM. It also does not help with sizing compressors or other components required such as wastegates etc.

Searching the forum does bring back information in various threads. It's just that often it's responses to specific questions and jumping between different threads is not the easiest way to take in all the info. I was hoping that if those in the know were willing to compile their previous info and maybe provide some general info/guidelines, that it would allow people such as myself to come up with a design for their application and then only ask the questions required to refine it to something workable. Ultimately (hopefully) saving anyone from answering the same question across various threads, as well making the great knowledge that is here more accessible.

Thanks
