There is a threaded hole on my compressor for a wastegate actuator that goes all the way through and is open to the inside of my compressor housing. Would it be a good place to place a fitting and feed my external wastegate its positive pressure or would there be too much turbulence and not a good boost reading?
Should I go a few inches from the compressor outlet up the charge piping?

Thanks

/\ bingo. if using an mbc or no bcs
if using ebc, it probably doesn't matter much since you can just ramp up the top end

 

hahaha i feel like an idiot now. Thanks for the info! Btw, you live in Indianapolis? Do I know you? I am Harold's nephew, I have his old red Miata now.

 

Sorry, the only Harold I know wouldn't fit in a Miata. In fact he lifted mine and moved it ~6 feet into a parking space for a company video

 

While Joe's article is great, Corky Bell in his book: Maximum Boost disagrees with hooking up the boost signal in the intake manifold. He in fact suggested the best location is at the compressor wheel (Point A in the above link).

 

Nice to see more Indiana people! I have my boost source there, but if I ever get a handle on my boost creep problems I will move it... as is it actually helps combat my boost creep issues.

I'm going to hook it up right after the intercooler. I think it will be ok since I have a small water to air cooler and the routing is very straight forward. I think if I had more piping having the source that far may lag a little, maybe that is why corky doesn't recommend it.

 

So does everybody else. Never reference wastegate from manifold. Joe also said that referencing from intake manifold was bad mmmmmmmmmmkay?

This is where he's wrong.

That book is extremely outdated.

 

The more that you talk to Corky, the less you will listen to him... at least that is how it worked out for me.

Keith

 

lol

his info is about 20-30 years old btw, before we even had electronic boost control.

 

Address your boost signal issues with Corky Bell himself. OP here is a link to Mr. Bell's book. Maximum Boost, to be exact page 148 on the book.

We don't care. The point is: It's wrong, and just because you're quoting something from a book Corky wrote using 20-30 year old info, doesn't mean that it's right.

Make sense?

Referencing from compressor housing is NOT ideal, no matter how many times you point out that Corky says it is. Pretty simple concept, and one illustrated QUITE well in the thread that was previously posted within this thread.

 

I want to hear Corky's response to how they screwed up Keiths (Twodoor) Begi S6 setup so collossally and how their externally gated top of the line $$$ setup creeps like a crappy unported chinacharger. I also want to hear corky's explanation of using crappy steel intercooler piping all the way into 2013, and switching to alum on their "new" system incorporating designs used by companies on miata's that went under about 15 years ago.

brb reading maximum boost for the answers to how maximum boost himself failed

 

I saw Keith's setup in person. He's got a nice tune on it, but with him illustrating everything that went wrong alone the way and how some of that stuff fit, i would have just put it all back in the box along with a steaming coiler, sent it back, and disputed the charge on my credit card.

Big props to Keith for having the skills/patience necessary to get that mess up and running as fast as he did.

 

You guys talk **** about a person who is a supporting vendor in this site and at the same time buy parts from this same vendor. WTF???I don't understand. .., but I would like to see him address his opinion on this topic. I read page 148 on his book and does have a valid point of view.

 

No, it doesn't have a valid point of view. This was again, QUITE clearly explained by the linked thread.


Are you dense?


As for the parts/kits comment... you have COMPLETELY missed the point, and/or you haven't bothered to look at all at what we're talking about.

 

That's your personal opinion, the fact is many people hook the boost signal directly to the compressor wheel and call it a day. In this particular topic the OP has a turbo external waste gate which is controlled by the spring inside the waste gate. To get quick spool all he needs to do is hook a manual boost controller available inline (between waste gate and compressor) and forget about it. There are tons of pictures online as to how to do this.

 

We buy parts when ignorant.... then talk **** after we get burned.

So you're a big fan of Mein Kampf too right? Nothing wrong has ever been written in a book.
