I just wanted to ask one question.

I am trying to decide where I want to hook up the wastegate boost signal.

Should I drill and tap the intake manifold or ;

Should I drill and tap the compressor housing outlet?

What are the potential plus/minus' to doing each. Are there any performance or drivability issues associated with the different locations.

Thanks for any and all input.

No issues with either location. There will be a very slight difference in pressure between the manifold and compressor outlet so a 1 bar WG spring will yield less boost in the manifold if the signal is tapped off the compressor housing... a fraction of a psi less, but still less.

Drill neither.

Install on of these in the fitting between the turbo and the intake pipe.

Be be aware that they charge more for shipping (1st class) than the fitting itself. Complete BS.

For an intercooled system (which I realize Greg doesn't have right now, but Duke does), isn't it better to get the wastegate signal from somewhere after the intercooler? I thought the pressure drops as the charge cools through the intercooler, making the intake manifold the best place to get the wastegate signal from.

Greg, in my case I got the signal from the intake manifold, but I left the vacuum line to the interior temp sensor disconnected so I didn't tap a new fitting. This hasn't seemed the affect the way the HVAC functions in the least.

Like I said, it doesn't really matter.
Let's assume everything is accurate... If you have a 1 bar WG spring signaled off the compressor and you have a boost gauge signaled off the manifold then the gauge will never quite reach 1 bar due to the pressure drop between the compressor and the intake manifold. If the signals originate from the same location then, in a perfect world, the gauge will read 1 bar boost. We are talking about a small difference in pressure in a well setup system... 0.5-1.0 psi or so.
I always tap off the manifold.

I tapped right off the manifold for the most accurate reading.

IMHO, you should not use that tap. Now, I know its not very likely, but what if the bolt comes loose, and that tap falls into the intake system? Especially if its after the IC! Using a welded tap somewhere is the most correct way to go. Just added insurance.

Doh, I didn't see the locking mechanism at first. Thats definatley a better tap than I though.

I wouldn't use it because;
1; it's very easy to just drill/tap for a threaded fitting.
2; punching a hole in the connector cuts the fiber reinforcment imbedded in the silicone.

More importantly . . . is the car running? 8)

Jeremy

Car is running excellent so far. I ended up tapping the compressor housing because I didn't want to remove the intake manifold and the turbo was still off the car at the time.

I will be installing my B35 intake soon enough and I will make certain to put a few extra ports in it prior to installation.(yes I already have the B35 head installed).

As soon as I have time to sort through the pictures I will post some of them up. Bye for now.

Ditto.

OK,
Ill play, doesn't the clamping force of the washer against the fittings back washer give back the structural integrity that was lost by drilling?

No, it wouldn't because the whole structure around the insertion point is affected and can create other issues. If something is designed like that, you don't mess with it. Metal is a different story, which is why the compressor or manifold was probably a very good place to put it

The burst pressure of a typical hose is a couple of hundred psi, it seems very unlikely that one of these taps could cause any problems at 10-20 psi on a street car.

Yep, I there with you brother. In fact, I have one installed and sleep quite well at night too.

When it fails and you overboost and blow your motor, will you tell us?

IMHO is very lazy way to do it and a totally unecessary risk. But hey, what do I know?

Never happen. The signal for the waste gate is from the manifold via a stainless steel line that you installed. The pressure from this fitting goes to the EBC solenoid.

Speaking of lazy, how about you answer my PM reference the heat exchanger.

That kind of attitude is goingt o get you an even quicker response.

You want something quickly than call me on the TELEPHONE!

I hate PMs.

Me too but it is a real PITA to call out from here.

Now just to clarify things. This would not be the best thing to use for the waste gate control. It is perfect for what I am using it for, and electronic boost controller signal to the solenoid.

I would also only use a stainless steel braded or hard line for the signal from the manifold to the waste gate for the utmost fail proof safety.

Why would yourspace be preferable for communication.

For that matter what exactly is "yourspace"

Some would say he was waiting for himself to invent the internet first so he could release his new creation. Right before he invented the hybrid and clean air.

I understand what Duke is saying about communication at work.. It's much easier for me to Email or Pm someone at work where talking distracts those around you. I would think at a military base it would be even harder. Greg I still want a ride at 5er Fest. Edited to save ShawnD some extra work
