Scott/Group,

I was just looking at the turbo set up that you posted. http://gallery.eaa326.org/members/semery/?g2_page=1 Thanks for posting.

It looks great. It is continuing my motivation to pursue the turbo. I also have the Conversions Concepts mount. I too will likely have to fabricate - read that as have fabricated since, contrary to my manly man status :-), I know not how to weld :-( - my turbo manifold. I like how clean and simple yours is.

I am trying to decide the best position for it. The current extension that I have on my engine - in order to clear the Mistral Injectors location puts my aftermarket turbo manifold perilously close to my aileron control linkage (about 3/4 of an inch, or so). Also, it is right up on the top of the cowling.

My question to you is, I did not notice a waste gate mounting place on your turbo exhaust manifold. Both my aftermarket manifolds have a place to mount a waste gate. Did I miss it, is the wastage internal to the turbo? which I think is how Mazda did it, but figured this was not the case with the larger T04's we seem to be using). Where might I add one to a manifold I would have made. Would the position be secondary to just putting it in the place with most clearance?

While I have learned a great deal about how turbo's work, I am far from versed enough yet. Is there a conventional wisdom as to when to use a waste gate. I thought they were standard and the primary means to control boost, along with a pop off valve (if that is the correct term and idea?)

Advice and insight is sought and appreciated.

Thanks in advance guys and gals.

All the best,

Chris
