the problem we are trying to avoid is high wheel speed during low ground speed (like a burnout)

Don't forget to point out how sensitive a 4 port solenoid is over a 3 port. 1% can make 3psi difference as opposed to 1% making 0.5psi

So a the 4 port could create less (.5 psi) or 3 port?

Nice video to reach out thanks

I love the video. Thanks for the knowledge. I've been looking for a 4 port setup for my Mazdaspeed3. I see that there are 4 port controllers and I'm curious if I can run one or will my ECU fight me the whole way?

real st. I've been a big fan of you guys. been following you guys for a while thinking about bringing my 93 Honda Prelude to get built. Are you guys. are you guys from you with H22?

Can you do a Video about 4 Port solenoids and frequencies vs resolution and how people need to adjust to help reach thier target boost?

Really good info. What frequency does the 3 port mac solenoid operate at aiming for 20-30psi.

I see it has been a few weeks seen the last video. With the holidays and all I could only imagine how busy you car. But could you do a tech tip on torque converter and converter lock up speeds

Jay, Have you seen boost spike with this 4-port? A local Central Texas shop was testing this on a 5.3 with twin 76mm Turbonetics w/holley dominator ECU and seeing boost spikes, from high to low boost like a roller coaster.

+Jay Meagher before putting it on the dyno and it was good. I was able to get it up to 40psi.

Hey Jay how would this work on a BW EFR using the turbo mount solenoid? I'm running this on my RB30 Skyline and will be young the boost and switching to e85. The ECU I'm using is the Haltech Platinum Pro. Any thoughts???

Have any plumbing diagrams for how this would work on an IWG setup?

i have a 1jz single turbo in a 97 Toyota Tacoma. i have a HKS ECV EX boost controller both vacuum source are directed from throttle body and 3 line going to side of external westgate. there is a open top fotting on the wastegate. it seems external is opening under high boost. what ypu suggest move the hose from side to top on the external wastegate.

Hi, I currently have twin small turbos and the wastegate springs are 0.5bar and I have a 3 port boost controller taking me to 1.2 bar. All works fine. However I'm hearing that if I go to a twin port wastegate and 4 port controller then I can promote quicker spool up. My ECU controls the controller and that may well already be slowing the boost pick up so wondered if this is actually worth doing. Its a 1100kg car mid engine RWD and has good traction. Am i also reading correct that if boost controll is via TPS then boost build up will be quicker when TPS increased due to boost already being created? Not sure if I have explained that correctly

Will it work on VNT Turbo?

So I’m trying to boost my Accord CVT, the problem is that it can’t handle the immense about of torque that a turbo unleashes all at once, so I have to turn the turbo into a supercharger by increasing the boost as the rpms increase and dropping boost before redline can this product help?

Hi... how this will work on a Volvo C30 R-Design 2010 with a geartronic trans im new to this . What Im trying is to get more boost on the k04... been watching videos of boost controllers to gain more boost . and now with this 4 port solenoid got little lost …. thanks in advance

I have plans to be upping power on my stock '13 Evo GSR to about 400 hp at the wheels and an aftermarket wastegate and 3-port were part of that plan. First of all, will my platform support the 4-port you're talking about here and secondly, what if any other mods/parts are needed to support this? Are only certain wastegates going to work this way? I'm bone stock right now and plan to tune on the street with an experienced e-tuner using Evoscan...although I have no idea if he has any experience with 4-port boost controllers. Thanks to all the guys at Real St.! These videos are awesome!!

+John C you are lucky enough to have AWD, so this wont apply as much to you at that power level. To acheive 400hp you wont need to lower the boost in 1st gear like an 800hp fwd or rwd car would need to. Your tires wont spin so in your case you could achieve your goals with a single 3 port solenoid.

Couldn't you just run the boost controller between your pressure reference and the bottom of the wastegate, then leave the top vented to atmosphere? Is this not recommended for some reason?

Hi Jay, sorry to ask you again, will this boost control solenoid work on my MK5 GTI FSI engine with a PTE5858 ? It's currently using the N75 valve and it's run electronically. Does yours work the same?

@jaymeagher1510

As long as your control frequency is the same and you're able to access the duty and correction approach to error it's just a solenoid. What makes the 4 port able to have the increased range is the fact that it's removing signal from the bottom of the wastegate's diaphragm and adding to the top of the diaphragm while a 3 port is just manipulating one or the other.

Boost by gear may not be your best bet if you're making decent power. I'd use the non driven wheel speed to do boost VS speed. It will help calm it down on the gear changes. I'm not familiar with the S300, I stopped using Hondata years ago as it's not really what comes in the shop. thanks

@jaymeagher1510

4 жыл бұрын

In most cases a 4 port will offer is the most range the system can mechanically make. The limitations are what your turbo can make for max boost with zero wastegate flow and what your wastegates can flow running base boost. You'd want give more information to get a more complete answer. Will your system hold 10psi without boost creep to redline? Will your turbo flow enough air to make your target boost at a reasonable back pressure/drive pressure? Basically what you end up with with a 4 port @100% duty is all the signal leaked that was going to the bottom of the gate and all available signal to the top of the wastegate forced closed. You'd plumb the 4 port just as the instructions state. Please be careful with octane at these boost levels, "bad coils" in your community are a side effect of detonation.

you would either need an aftermarket ecu, or you wanted to stick with a stock ecu, you could purchase a stand-alone boost controller that comes with a controller unit and solenoid...but you would need some way to tune the fueling on your stock ecu if you increase the boost

+Alexander Dougin Some applications can, some can't. Your same wastegate and boost control setup may not get the same results on an LS1 with an 88mm or an evo with a gt30r. It's a good place to start when planning out a build because there are lots of variables that can affect this right? Engine size vs Turbo size, Turbo size vs Wastegate size, wastegate placement, ethanol or gasoline. And even more variables like boost behavior. For example, a big engine with a small turbo vs a small engine with a big turbo will both have different shaped boost curves with the same wastegate spring. Wastegate position may cause a high boost spike and fall off, or creep to higher boost after reaching target. The "double the wastegate spring" rule is a good starting point for someone laying out a build. It will cover the bases for many of the combinations of variables just mentioned, and leave enough room for the ability to have solid boost control without unexpected or undesirable boost behavior. Every specific application will be different and the spring can be adjusted as necessary once you have a place to start but at the end of the day, the 4-port solenoid method will achieve a wider available boost range on the same wastegate spring than a 3 port will. So if you max out the spring on a 3 port (whatever that max may be), and still want more boost in high gear, swapping to a 4-port solenoid can help you avoid upping the spring. but if your application can give you a wide enough boost range with a 3 port then you wont really need the 4 port.

You'd have to use some sort of stand alone boost controller. You could get any one of the electric units on the market. Turbosmart makes a nice one. With the high drive pressures and short engine speed window on a older diesel engine you normally just pick the turbo that makes your power goal and let it eat whatever boost the unit will make.

😊

Fucking Tremendous!

At 2:40 the 3 port solenoid is setup incorrectly isn't it I run mine which is identical port 1 for turbo pressure in, port two goes to wastegate and 3 is pressure bleed you've got the bleed filter on the wastegate out port?

@jaymeagher1510

If you're using the solenoid to reduce the amount of boost that reaches the bottom of the wastegate you would plumb it the way you're talking about. If you're using a 3 port to add air to the top of the gate you would use it the way it's pictured. If you had an ecu that offered the control you could use a second 3 port solenoid and leak signal to the bottom of the gate and add signal to the top. This route you'd duplicate what a 4 port does. If my explanation doesn't help you look up the instructions for the greddy boost controllers and there's some pictures you can use to get a visual aid. thanks
