Hey ppls,

Well, I've made my kit up and it works great. Takes some tuning to get it right, but when it's right, it goes great.

Kit will come complete with two valve and check valve, as described in Autospeed articles Autospeed article

Valves will be mounted to a bracket, all you will have to do it mount the bracket and plug in your boost lines.

Price change : $130 (plus shipping which will be $15 anywhere in Australia)

I will require payment up front, and the kits should be ready in 7-10 days.

See attached pic for the example of what it will look like.

Okay, I noticed the following.

The thing takes a little while to set up, but once set it says set.

Tranisent boost response, ie getting on the throttle in higher gears is much better, insted of slowly building, it just goes straight up to full boost.

First gear is not all that noticeable simply because my car revs out so fast in first anyway.

But spooling is definently quicker.

Possibly interested...

Do you just mount in the normal position between the presure point and actuator? I'm a bit of a dumb arse when i comes to the mechanics of the turbo and am concerned i would not know where to install it...

So your saying the advantage is that the boost comes on quicker than a normal single stage controller? I read in your first page on this that it acts more like a Electronic Controller. Is this correct?

Regards,

Jeremy

PRICE CHANGE. NOW $130 complete

GOT SOME BETTER QUOTES FOR THE PARTS.

Need at least 5 people though.

If we get 10, then price drops to $125 each.

I'm in for sure. These things are great and the theory is sound. The fact you can controll how quick and how strong boost comes on is awesome. I run a standard bleed at the moment and was keen to get one of these kits just could never be farked building it :)

This is a slightly neater way to do it Later on I put it inside the cold air box

Hey Jay,

I notice you've got the upgraded pressure regulator there. Did it make a big difference in controlling boost? was it worth the extra $$$???

That's a good question and something that I might investigate.

I drove to Bendigo and back today and had a lot of opportunities to play with the boost control, mainly slowing down to 80 and dropping it up to 110 (legal limit) to see what the boost does in each gear.

What I found is that the boost will spool to the set level (first valve) in first and second no problem, but then third gear, it would boost to set level and then drop right off, like the wastegate was flying open.

The boost would eventually build to the peak level, but not until 5-6k rpm.

So tonight when I get back, I removed the new second valve (peak boost valve) and replaced it with my old bleed.

Problem solved.

I'm going to investigate another valve that I'm sourcing and try it on my car first.

I hope you all appreciate this!!

I think it's probably not worth the extra cash. the system works well with the one way valve ensuring that the line to the wastegate loses any contained boost pressure as soon as you take your foot off. If you'r finding that boost builds too slowly it's possible that the wastegate is starting to open too soon. This is controlled by the other valve.

I found that the system is sensitive to it's ambient temp. In the Audi it sits against the firewall on the cool side of the motor ( The origional car lives on the Gold Coast) The usual mount point in the Skyline is in a place that can get hot. Thats why I moved it inside the airbox

The reason I finally removed it was I couldn't keep the same boost in all gears, eg 1.2Bar in 1 and 2, 1.4Bar in 3 and up to 1.7 bar in 4th + an E-Boost came up at a good price.

I never had a problem with slow boost buildup or falling off. I was on full boost by 3100rpm in any gear and at least 60%boost by 2700 rpm. It is a good system....but you need to really understand how it works and be prepared to fiddle to get it spot on.

After fitting the old Bleed valve, I now have the impression of the steering wheel on my forehead, as boost cut happened heaps last night.

Can't get it right.

I did have a little restrictor in the system before the first valve as one was fitted in front of the old bleed valve.

I have now pulled that out, but not had a chance yet to go for a drive.

I have to go out this morning at some stage so I'll have another play and let you know.

Can anyone explain this to me like im 7yrs old?

As I understand it a boost controller lets pressure out so the wastegate diaphram doesn't open and allows the turbz to deliver a higher pressure of boost . i.e. "boosted" car.

This looks like it has 2 valves? I read the autospeed article 3 times and still don't understand the difference.

Could someone explain this to me please?

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
