Hey guys,

Just wanted to let you know that for awhile now I have been thinking of emailing Synapse because to put it bluntly they look to have a kick *** product that is marketed like ****.

So as some people know Synapse Engineering are the first to provide a diaphramless design in their wastegates and blow off valves. This means, reliability and more importantly response and control.

Personally, I would think that this would be a hot fire item (the Synchronic Wastegate) for the single turbo crowd.

For those of you who are not familiar with them here is there website:

http://www.synapseengineering.com/

A few videos about their product you can visit streetfire.net and just search "synapse engineering" there is also a video in their archives section.

Just to be clear, I am in no way attached to Synapse Engineering, I get no commision, sponsorship deals or christmas cards from them.

So back on the subject. I sent Synapse an email today and I expected maybe a reply. As anyone who has ever emailed a manufacturer has experienced it sometimes takes days if not weeks to get a reply to an email and that is IF you get one.

Well I emailed at 2:31PM and I got this reply 6 MINUTES later:

Alex,

Thanks for the feedback. I actually can't divulge the details yet, but I
think that we will be making a huge mark in the rotary world should all go
well with a big name racer or two.

The BOV is universal in that you can actually interchange the flanges. A
video still needs to be made to demonstrate this feature. So it should be
an easier install for those with factory piping because I understand how
much fabricators will likely charge customers. Ultimately, the features of
the wastegate should be most helpful for the Rotary crowd, especially with
the flexibility in tuning that will be available with the Synchronic
wastegates.

At this time we also are not pushing hard for sales because product is not
readily available. In the next 2 months we will are building up stock and
will adjust marketing and outbound information accordingly.

That's pretty fast!

 

Looks like a pretty nice product. I hope they put some sort of cover over the valve so nothing can get lodged into it.

 

damn ....and i am just in the market for a BOV ...so this could be something

 

I looked in to their BOV a few weeks back but not even their distributors know when it will be available, they don't even have a release date. I wasn't aware they have a wastegate as well, though.

 

Like Peter told me it should be in the next few months.

If you look at their design it is pretty much meant to be rooted.

If you can see the HKS vs Synapse BOV, the reaction times are stunning.

It was really the wastegate that got me, I mean even if you can get 200rpm of faster spool it is a halfway between journal bearing and ball bearing.

 

I posted info on this a while back in tha video section. Emailed them about tha interest from people from tha rotary community we're giving me...maybe I got them interested in us?

 

Has anyone tried these yet? Their FPR is available and mounts directly to the rail, like OEM.

 

Putting a bump for searching later, I would like to hear from anyone that gets these...

 

i wouldnt say thats the world's first diaphragm-less BOV, ever seen the TurboXS RFL? no diaphragm, solid piston with a spring.

kevin.

 

Is this thing a hoax or what? I would love to hear some review or seem some actual facts about the product. I would also like to test with this but can`t seem to find much info on it. Anyone have any updates or experience with the synchronic wastegate? I am not to interested in the BOV though.

 

One of those big names in the rotary world is Abel Ibarra. There are a few videos on youtube of his RX-8 doing some testing with the synchronic wastegate

 

I recently recieved two of their new BOVs (the last two that vendor had) and having A-spec put one of their WG on my 500R kit that being built.

I will post my thoughts on performance of these units when I get my car built and on the road.

 

Great! I am looking forward to reading what you have to say about the WG afgmoto1978

 

I too am also interested in what you have to say about this BOV

 

Is the Synapse BOV and Wastegate good with my FD3s Twin Turbo??

 

Any new word?

 

I got a new word. Im using their 40mm wastegate holding a solid 11.5psi on low boost, and 15psi on high. The actuator has 3 vacuum tees that allow you to set it at 6 "boost levels" (not actual psi springs) ranging from as low as 5psi to 20+psi ON THE SAME SPRING. The kit also includes a stiffer 60lb spring to go a bit higher. This wastegate is very responsive and holds rock solid boost. All I can say is that the Synapse Engineering wastegates are the best bar-none AND their prices are very competitive. I also have their BOV and it's not a bells-and-whistles BOV, no "sound adjustments" on this thing, just functionality and kick *** design. (Sounds like a "WHOOSH" if you're curious.) The BOV uses a Y tee for its DUAL vacuum ports, giving it really good response to boost/vacuum changes. If you need to recirculate for your MAF, it comes with a recirculation fitting installed so you can plumb it back between the air filter/MAF and compressor inlet allowing people that use MAF on their turbo cars to run the BOV, and if you just want some extra OOMPH for the compressor to spool quicker you want to vent back to the compressor inlet. If you like to vent to air, this BOV is a pull-type so when under vacuum it's open and when boost is created it shuts. Now the purpose of it being open under vacuum is if you place this BOV closer to the throttle body (as opposed to between the compressor and intercooler) it will help your engine get past all the restriction the turbo and intercooler system creates under vacuum consequently eliminating low RPM bog. With this setup it's recommended to use a small K&N filter on the recirculation fitting, otherwise your engine's getting dirty air when under vacuum. I'd say the naysayers should try em out, they just might find a permanent home in your setup.

PS. I am not affiliated nor am I paid by Synapse Engineering for endorsing their product. I just know they're the best.

 

Sounds like I know who to go to when I go single.

 

What is weird is that since speaking with Synapse last their website has yet to be updated.

I am slowly seeing wastegates for sale, so they must be getting out there somehow.

 

Wow, I just so happened to come across this post while googling. You're the guy that I've been looking for. I was watching some YouTube video of a bunch of cars driving by the camera in NY caravaning to SevenStock, right? I heard that it was one of our Synchronic BOVs that blew off from your car.

Tell me which port combos you are running to get your 11.5 psi and which turbo?

Also, give me a call at the office so that I can fill you in on a tuning tip for the BOV that will optimize it even further. 858-457-1700.

 

I am very interested in this BOV for my FD and FC, sounds like it is a very good design etc. my question is, when do one need to have it with the recirculation fitting installed ?? is this nessesary for the FD and FC or can you went it to the air ? thank's.

It's only necessary for stock closed-loop MAF setups so you don't run rich between shifts. If you have a standalone that uses open-loop and a MAP sensor you can vent to the atmosphere. This BOV stays open under vacuum to bypass the turbo restrictions so it's recommended that a K&N filter is fitted to the dump fitting, that's how I run mine.

 

i saw this on youtube...its very ingenous. pretty sure they said it was pretty costly

 

So far I'm really impressed with the performance of the BOVs. I added control valve filters to the unused pop-off valve nipple to prevent contamination.

Mounting the BOVs to their flanges without damaging the o-ring provided was very difficult. Be sure to lube that o-ring seal thoroughly before you test fit or permanently install the BOV. Also tightening the set screws are a bit cumbersome if installed in a tight place.

Will post video later for a reference of the sound for those audiophiles.
