Adjustable boost actuator???

[snwman77]

So why would I need a Boost controller if I have an adjustable boost actuator?? So you know what im talking about. A boost actuator is the unit that opens and closes the waste gate and the boost controller is the little unit that has the knob that you can turn to raise and lower the amount of perssure to the boost actuator so it will open and close the waste gate as your intake pressure goes up and down. So what im asking is what is the need of the boost controller if you have an adjustable boost actuator??? You should be able to adjust the spring tension in the adjustable boost actuator and that would then open and close the waste gate according to intake pressure or am I all wrong on this?

Because the guys that are always trying different boost levels rather turn a knob, then play with e clips, and hot exhaust housings, etc. And depending on the kit, getting at the WASTEGATE actuator could be a real pain in the ***, although this isn't an issue on cpc kits.

So I ask again does a person need a Boost controller if he has an adjustable boost actuator??? and why.

Do you have a port for a boost reference hose on your boost actuator?

That's the question I was asking last time.

If you want to change boost level now, how do you do it? knob, box...?

I didn't understand what was gained with the unit you mentioned.

NEED? No. Ease of adjustment of turning two fingers, vs stopping, getting out the screwdriver pliers and wrench, loosimg the e clip in the snow, etc...

All a boost controller does is bleed off the boost source going to the wastegate, less boost signal going to
The wastegate actuator, the more boost it makes before it gets enough source to open, and control boost.

Do you have a port for a boost reference hose on your boost actuator?

Yes It has a port, Thats so when the sled is making more boost then you want the waste gate will open and boost will be set to the amount of spring tension you have the Adjustable boost actuator. I would think that having a Adjustable boost actuator and a boost controller would be unnesasery. You could be adjusting the Adjustable boost actuator and adjusting the boost controller and you would be fighting yourself. You could tune boost up with the Adjustable boost actuator and then turn the boost down with the boost controller and end up at the same boost to your engine. And on top of all that the boost controller restricks flow in the full open position so if i didnt run the boost controller would the Adjustable boost actuator open too fast even with it turnd up to max boost?

Right!!!!! So why would I need a boost controller if I have an Adjustable boost actuator???

Once the boost actuator is set so the waste gate is closed you should not need to play with it. MY Adjustable boost actuator can be adjusted with two fingers, I just need to turn it and it will apply more or less spring tension to keep the waste gate closed for more or less boost.

Alright then. We made a big circle and got nowhere and you have your awesome adjustable boost actuator. Did this thread really just happen?

Yes it did really just happen!!! If you know so much about it tell us.
I Know what both parts do, and I think most of us do in the forum. Im asking if I need Both working together.

no you dont need one. the problem is on some adjustable wastegate arms, you can only adjust them so far... some want MORE boost.. and then you NEED a controller. if you set yours to a level within the wastegate's adjustable range that you want, and have no urge for ease of changing levels, then NO< you dont need a boost controler

I dont get the point of this thread, it seems that you keep seeing answers and asking the same question.

also, its a wastegate, not boost actuator. just for ease of explanation.

I dont have an ajustable arm on my Adjustable boost actuator. My Adjustable boost actuator has a spring just like the old ones but i can add more spring tension to mine. Adding spring tension will add more boost. I keep asking the same things over and over cuz non of you know what im asking, you just want to tell me what a waste gate is and what these parts do. I know what they do. and you still didnt answer my question.

WTF turbo are you using? Do you have an aero or some hokey setup on a garrett? You are not reading the replies everyone has gave you. Your right... YOU don't need one. You obviously don't get it, you have base spring pressure on the wastegate! actuator, say 5psi, then your boost controller can up the boost from that point, by bleeding off the boost signal going to the wastegate actuator.

This is now beat to death...

 

[badass1000]

I usually don't reply to this **** but damn.... You can't fix stupid.
Your question has ben answered several times and with great detail. If you can't figure it out by now maybee you should get rid of your turbo.

 

[badass1000]

what a moron. maybee you should be more specific in your question then. Because no one here gets it but you.
Simply put no. You do not have to have a boost controller.
Yeah... I don't know ****. I have never had a turbo with a internal gate. Always had a tial external wastegate. Boost control is not really that necissary on my sled. I set it and leave it. I don't use a boost controller. I change the waste gate spring. I may change it a little once in awhile, but changing on the hill is not necissary. clutching, suspension, and fuel changes are required when making boost changes. Not going to change fuel, suspension, or clutch on the hill.
This is what I use on my turbo street legal drag bikes:

nlr ams 1000. ben useing one for about 4 years now on a couple different street/drag bikes. boost control is a big part of street legal drag racing. My bikes make more power then I can get to the ground. ams 1000 is required to put down 11psi in first gear. 475+hp at the rear wheel on my new turbo gsxr 1000.

Both ?

If you have booth good if you only have one good and if you do not have one that is good to. No you do not heed one two but there is nothing wrong with having two do you need it NO.

looks like snwman77 deleted his post between my lasts two posts stating I don't know **** and he is a genius.

How come you erased the smart comment? MM Did not snwman77

Well, we ask a question or make a suggestion and you not only answer, you explain what everything does and how it relates to everything else. You keep answering your own question. I can't help but be a smart You're crazy! Are you trying to put on a school and make it sound like it's not?

Like coxy said earlier, no you don't need one, but you apparently already know this. Unbelievable!
