I saw this wastegate by Synapse Engineering... new product on the market because the diaphragm has been eliminated to a piston type sealed by an o-ring.

Check out the video on youtube.com and give me your thoughts. I’m just sick and tired with my HKS 50mm Boost spiking. They also make a piston type BOV.

Holla back,

andre abel ibarra uses it on his 3 rotor drag car it works very well.

 

How long could an O ring last near those types of temperatures?

 

Is this Roger, Joey or Gordon... Been along time!




Yes, i know Abel ibarra uses it on his car, but I was just inquiring if anyone else attempted to use it locally... if so, what`s the outcome results.


I think I`m going to get one, but can you preload it down to 12psi and then use a Greddy Profec-b to regulated boost between High/Low. Reason I ask, is because the video said to was 45psi preload and then 60psi high boost!


Please advise!

For any car thats not a 1000hp drag car, all you'll ever need is a Tial 44mm.

 

I`ll call TiTan and they said the cost was 350.00 same amount as the Tial.




Just another video on the explanation

I still think its an amazing piece of work.

Watching this video is just sad for any other wastegate.

I just installed one on my Race car and they look good for the money.

The good thing is that you can choke the 50mm down to 26mm,36mm,40mm and 46mm.Very nice ehh.

 

Why would you need a wastegate that is 100% sealed. In a real world and not a bucket of water it is not going to make ANY difference at all. I guarantee if you pressurized an intake or exhaust port in a piston engine you would have the same amount of leakage around the valve guide.

These may be the best wastegates in the world but i just don't like how they advertise them. Instead of just emphasizing their quality they are trying to prove that they are superior with parlor tricks and smoke and mirrors.

I will stick with my Tials.

 

So how is it, any boost creep at all?

 

Has anyone retrofitted any other wastegate to an FD HKS cast iron manifold?

 

I agree completely, It's gonna take more than some guy in a garage with a bucket of water to sell me.

 

copy catters they stole the idea from jgs wastegates
I have one of ther 50mm's

 

So how do you like the JGS Wastegte?

 

works good, but the spring that came with it was too soft like 6 pounds
when I was going for 30+ pounds at my last tuning session, It would not go past 12 PSI with the Profec Type S boost controller turned up all the way.....They sent some stiffer springs.which might equal 18 PSI....I do't like there spring selection
even Tial 60mm spring combo won't exceed 20 PSI
I don't have plans for a low boost setting for the street or Pump gas

 

That's one of the good things about the Tial. You don't need a stiff spring to get high boost.
I've got up to 47-50psi with their base spring!
No other wastegate can come close to that.

 

I will never buy from synapses They have great marketing, but I just dont like them as a company.

Synptic is on here...... care to chime in?

 

ohhh I hope they do.

 

I am trying a new setup with this wastegates.I have had others that leaked

during hard boost,Tial,innovative wastegate,turbonetics,etc...

I am going for high boost big power,(50-60psi).I am just trying stabalize the

boost at the high rpm range.I have had some really bad boost creaps when i

go past 40-45 psi,because most of the wasteges i have tried leaked through the

stem below the base causing the wastegate to shut down close.

Most of the wastegetes don't last 5-10 hard runs that i have tried.Synapse looks

like it seals really good with boost.Me and my buddy have been doing some

on the bench experiments with co2 and they hold on the spot with no leaks.

I have tried the others with the same experiment and they don't stay stable.

My new setup is a monsterous super thumper 91mm on my 13B Rx3.Maybe

later on we won't need no wastegates,i have seen others run without

wastegates just all out boost up to 75 psi on methanol !!!.

 

Brent Rau doesn't run any wastegate.

 

A leaking wg can lead to poor boost control. I lived with this on my HKS race wg for years trying different boost controllers to fight boost variation with no sucess. Maybe a Tial can control boost better than the HKS without this fancy wg design that synapse has released.

 

Maybe in a fish tank.

When a wastegate is installed and operating in a car you have less pressure differential. In the fish tank you have 30PSI on one side an 0PSI on the other. On an engine under boost you have slightly more pressure on the exhaust side than the diaphragm side. And even if you had a small leak at this 5PSI differential the flow of the hose going to the wastegate would easily keep it pressurized.

I'm not buying it.

 

that underwater test was done with a knock off wastegate. some cheap piece of crap that is known to leak. how about they get a genuine tial gate and do the water test.

 

Cause they can't afford one...

I find it funny that THEIR discharge section looks suspiciously like the Tial unit.
Or did Tial steal that design from somewhere else?

I find it funny that they bash the poppet design, which has been used successfully for decades, is suddenly obsolete?
