Boost Connect Fittings are Leaking

2011-03-02T10:19:46+10:00

Below you will see an image of the aproximate length of hose that is required to be pushed into the push connect type fittings. The hose is supposed to be inserted about 16mm from the end of the hose. Also, note how the hose is cut at a clean 90 degree angle. If there is a slant, there is a chance that the hose may not seal properly.

How do I connect the polyurethane hard lines to my engine?

2011-05-05T05:12:49+10:00

By utilizing some of the factory rubber tubing, it is easy to connect the hard polyurethane tubing to the engine.

Take a look at the image below. In many applications, it is possible to insert the Boost Connect polyurethane tubing into the inside of the factory rubber hose and clamp the connection with a factory clamp or ziptie if a clamp is not available.

What is a Port C delete and what is the service procedure?

2011-07-13T04:56:53+10:00

Port C refers to the chamber behind the piston acuator. In previous generations of the Synchronic BOV port C was an independent chamber that needed an uninterupted boost signal to function properly.

Pressure flows in from the side port and pushes against the piston, this equalizes the pressure in both the inlet chamber and acuator chamber

In newer generations of the Synchronic BOV we have eliminated the need for an independent port C fitting.

If there is no port C on the side of your valve you have the newest version of BOV. Earlier versions with Port C deleted had a hex cap bolt installed on the side of the valve to seal off where port C used to be.

Port C delete service requires complete disassembly of the BOV to port the casting so the C chamber can receive it's pressure signal from the BOV inlet chamber.

Here you can see the internal port C.

If the Synchronic BOV you have purchased does not have a port C, then you have purchased the newest revision of the Synchronic BOV. The newest revision of the BOV has port C internally built in, therefore the installer no longer has to spend extensive time sourcing a boost only source for port C.

The functionality of both versions of the BOV is identical.

Can older Synapse BOV (those still have port C) be converted to internal boost feed?

Yes, we offer this port C delete service to those whom have the older version of the Synchronic BOV, and wish to update their BOV to the latest revision. The procedure is listed below:

Go to www.synapseengineering.com/support and start a service ticket record.

Fill out the form in this link for the port C delete service, and then print it out.

http://www.synapseengineering.com/archive/tech_support/Synapse_ServiceForm.pdf

The user must send in their BOV, the completed service form, and include a self addressed UPS or USPS return shipping label for sending the product back.

The Service fee is $35.00. You may send the payment via PayPal to: info@synapseengineering.com. If you wish to pay for the service via credit card, please contact our tech support department directly at +1 (858) 457-1700.

The service turn around time is 5 to 7 days from the day our service department receives the package. Your online ticket record will be updated accordingly to help you track the progress.

My BOV leaks at idle or low load situations!

2011-09-23T08:26:47+10:00

If you feel that there is something wrong with your Synchronic BOV being open at idle, do not be concerned. This is normal, and your BOV is functioning as intended.

By bypassing the restriction of the turbo, intercooler piping and all the surface area of the intercooler, you get better throttle response when coming off of vacuum, as well as fuel economy (if you care about that sort of thing). The engine does not have to work as hard to overcome those restrictions when the BOV is venting at idle or low load situations.

However, if the “hissing” sound is not to your liking you can switch to a different port configuration. The Synchronic BOV has 3 configurations to allow for initial reaction (opening) of the valve. The order of fastest to slowest initial reaction (opening) is B --> A+B --> A.

Port Configurations:

1.) Port B to intake manifold pressure, A to atmosphere: If you have a very fast spooling turbo/sc, use this setup. Allows for the fastest valve reaction resulting in fastest throttle response, as seen on our bench tests.

2.) Port A+B to intake manifold pressure: Recommended setup for most people. The valve will stay closed longer than if using just port B.

3.) Port A to intake manifold pressure, B to atmosphere: The valve will stay closed longer than if using port A+B.

What improvements have been made to the Synchronic BOV?

2011-02-10T08:16:26+10:00

Improvements to the design are the following:

Elimination of port C on the side of the BOV- This port is now internally ported on the design and is the hallmark of the latest revision. Performance of the BOV & it's ~17 millisecond initial response time remain unchanged. The original design with an external port C was made public in case there would be the occasional application that required the boost-only source to be plumbed before the intercooler to make use of the pressure difference that may (or may not) exist before and after the intercooler. We have always had our own units internally ported for simplicity and have rigorously tested & validated this change for over 3 years. We will still have the original design in limited quantities and available only for special orders and industrial applications. We believe that the benefits in having one less connection to plumb (or fail) far outweighed the 1% of users out there that needed the externally ported design.

Change to 1/8th NPT threaded vacuum ports- This design change has eliminated the use of the small M4 brass fittings. Although the initial design was compact and very light weight, we received enough feedback that prompted the change. We want to show that we do, in fact, listen to customer feedback, take it very seriously, and will only make a change after significant testing. With this change, you will no longer be able to over tighten and break brass fittings. You can also use our boost-connect fittings, which includes a 90 degree fitting for use in very tight installations. You should also know that this new back cap design is backwards compatible with even the very first Synchronic BOV released to market. You can upgrade your Synchronic BOV to this latest back cap using kit # SB001A.KIT022.

Old Brass fitting vs. 1/8npt vs. 1-touch pneumatic Boost Connect fitting

M4 mounting bolts- The mounting bolts have now been changed over from M4 set screws to M4 bolts to give users the ability to apply more force when tightening down the BOV on mounting flanges.

New mounting flange geometry- This new design eliminates any chance of o-rings getting damaged upon installation.

All of the universal Synchronic BOVs & application specific kits available in the market today should include all of the improvements above.
