but you have NEVER seen it in action howcan you say it is not worth it?? what if you put it in and your car picks up .5 of a sec down the 1/4??? i know heaps of ppl that have spent alot more than that to make up simular resaults....

as i said ppl with ANY controller come try it out and compare

sewid...

"Gas filled what? A valve like this works using a spring and a diaphragm. Are you thinking we're all complete morons or something?"

No, do some homework, and then come install this in your car and call me an idiot if it goes the same...

This is coming from a guy that says "using gas ... keeps the temps cooler inside the valve"... Yeah you're a real expert. :rofl::P

No wonder this thing improved your performance, you were using a hairbrush as a bleed valve before.

If its not simply a spring/diaphragm device and actually uses gas, the gas sure isn't there for keeping the temperature down.

Dude you are an idiot.

"Gas keeps the temps inside the valve down"? Are you a complete imbecile and believe your own BS? What relevance does the temperature of a bleed valve have to anything.

Go and crawl back under the rock from whence you came little man.

Sewid you really need to do some research befor making comments like this....it may save you from presenting as a complete twit.

Ok,

At the end of the day, there just isnt enough facts supporting this 'very special boost controller'

This is a small world, and something thats this good would travell in no time, and a week after it came out, it would be used everywhere and be as common as a bogan in an old commonwhore.

Ive been into imports and turbos specifically for a few years now, i own one myself, know people that own turbos and have done a fair bit of work on turbos.. and i must say, in all that time ive never heard or seen of this 'very special boost controller'

Now if it came out as part of the Audi's or whatever, then surely major workshops etc would know about it, and be using it?

why arent they?

'Tis a scientific world we live in, without proof, im just not sold, sorry

the gas is used because when you push more power/boost air temp inside the turbo raise correct??? ok let go back to year 7 science.... what happens to air particals when they heat up.... thats right they expand (see where this is going here)... when it expands the air becomes thinner (looses viscosity) ...would i be correct in saying alot of boost controllers start slowly raising the boost (higher boost in taller gears sound familier???) now what if that air is cooled when comes into the valve .... shall i keep going????

reson for em not getting around yet is that they have been under developement for ages getting the porting gas type ect correct and consistant

Guest INASNT

when u raise the boost the boosted air isent going into the pressure pipe that controls the wastegate opening and closing. The amount of thermal transfer going from the turbo to the wastegate to the rubber hose to the boost controller is so minimal in a 1/4 run, the gas would not do shit to make u do any quicker 1/4 time.

listen. Can i get a accurate answer to this question. Will this super doopa pneamatic valve do a better job than my APexi AVCR?

Im using the apexi to limit wheelspin in 1st gear. That alone is reason enough to leave it there.

mx83toy whats your answer to that?

Sewid   you really need to do some research befor making comments like this....it may save you from presenting as a complete twit.

Huh?

I've pulled apart valves like this many times myself. im yet to see one that isnt built like that.

My guess is it would do just as good if not better than the Apexi in terms of control of the set boost. it does not have any of the extra functions of the electronic boosters except to control "how the boost comes on"

ps Hope to find out for myself towards the end of the month.

Look I admit i might be wrong about EVERY relief valve being built using springs/diaphragms because i cant say ive looked at lots of different valves from every manufacturer. I have looked at many and pulled them apart to find that mostly they look the same inside.

But your attempt at explaining why gas is used here is technically flawed and completely wrong.

1) This valve is small, it has no cooling mechanism (compressor, radiator, etc)

2) Cooling air quickly requires a lot of effort and a lot more hardware than this valve provides. This is what we all get bigger and better intercoolers for.

3) Whatever gas they put in this valve is not immune to the laws of thermodynamics.

4) Ergo the gas will heat up to ambient or higher temperature before the car even starts up. The gas will then reach the same temperature as the air passing thru the valve quite quickly.

Even if the gas is stored compressed it is not going to be any cooler than ambient temperature. Only the expansion of that gas will result in any cooling effect. Of course the expansion of the gas means the gas has to go somewhere, into the atmosphere probably? And if not into the atmosphere it will need to be recompressed to perform the useful cooling work again. I dont see a compressor attached to this very special boost controller.

look man i didnt invent the thing....to my understanding this is one of the functions of the gass.... i've gone alot faster with it compared to other controllers full stop. you want to try one out, cool come down,

you want to bag it out come up with something better yourself, and then prove its better else...

    • Don't "upload" the pictures. Just copy the picture direct from somewhere (I usually am pasting screenshots or something else that I have on the clipboard as an image, not as a file" and just paste it direct into the post editor. Just like you were pasting it into a Word doc or something. You can't damage something if you lift it where you are supposed to. If you look carefully at the correct jacking points, you will see that they are reinforced right there. And nowhere else. That is where the "foot" of the factory jack is supposed to sit. That's why you need rubber pads with slots. 10mm might not be deep enough. Note also that the slots are not required if the pinchweld has already been slammed flat. You could just lift it at the correct spot with a flat pad, because the damage is already done. No point in making worse though, if it is recoverable. IF. Yes, that's called a chassis rail. You can lift carefully on these, if you spread the load. A decent block of wood is good. But keep in mind what I said before. Any time you start doing this sort of thing, you are off the normal path and into "be bloody careful", because it is obviously not stable. Dumb. The refinforcement is already there. See above.
    • yeah looks like they've been lifted there previously but with solid not slitted rubber blocks. I'd just bend them back (combination of vice grips or hammer with some sort of drift, then hit the area with underbody protection paint. As for the siderails, I'd call those chassis rails and that is exactly what I meant about being careful with the balance point. You can probably lift off them at the point where the 2 pieces overlap, but you need to be careful with the forward balance of the car if you do when the engine is in....sills are a better choice. I guess you could weld some reinforcement in the sill area near the jacking points but it shouldn't be necessary if you use blocks with a slit. If you do want to reinforce it I'd use square section equal or taller than the seam and then just use flat rubber blocks for lifting
    • driver side sidemember and jacking point (looks the worst by far) driver side rear jack point passenger side sidemember and jack point passenger side rear jack point   Ignore my mug on the last photo. Turns out I was just too stupid to properly use the forum's attachment feature previously
    • Fk me, I guess next time I will try to use the onsite attachments feature. I find it hard to work with so far though because I can't move the images to where I want them to be. I will try to make a separate post with just images. As for lifting. The work I need to do for now involves the exhaust and engine mainly, so the arm covering the jacking points is not a problem. But I don't want to bend in the whole sill or underfloor by lifting the car at the original jack points. I found some rubber blocks, 125 by 125 with a 10mm wide and 10mm deep cutout, which I'm hoping will work for not hitting the jacking rail. The sidemember, as seen in the service manual, are the rectangular frame rails that come from the front of the car and go alongside the gearbox and downpipe. Those that get crushed inwards if you use them for a floorjack. They are already slightly bent in from being used to hoist by other people. I think cutting off the jacking points and welding or bolting on a reinforcement plate along the sill might not be a dumb idea. Or is it dumb?     A 2 post hoist is what I'm gonna work with, but not for any underbody work, just leaky engine and exhaust work so far. Depends on what else I find that might need immediate attention. For metalwork on the sills I think I'd just bring the car to a panel beater. What's your take on getting rid of the original jacking rails and putting reinforcement plates along the sills?
    • Yeah titanium always looks cool but I don't need that, just regular pipes would be fine. But I am really struggling to find any full hardpipe kit that is still for sale.
