Gents ,

can any one shed a little light on the most effective way of manually pumping up the clutch pack from in the cab and can one mount a guage to decipher as to how much lock up ones applying - eg 10% through to full.

I don't really need as a street car but more for drag situation.

We have been working on the electrical side of things and have hit a wall - so for now i would like to look at this option,

Another approach may be finding a way of manually stimulating the hydraulic pump via electrical switching .

Any thoughts or experience here.

I have started another thread in regard to simply attempting to trigger the Attessa to work with no ABS in place and have all but given up , we are so near as well.

Oh well lets have a look at this in the interim.

All input taken seriuosly and appreciated. :P

Ahhh....

I've just moved back to Oz and realised I've left a lot of GT-R info on my old computer overseas - including an article on how to set up a manual hydraulic transfer case lock-up!

I'll see if I can get the article back from old contacts, but from memory it is common in Japanese drag racing circles to use a manual hydraulic lever to pump up pressure in the ATESSA system to lock up the clutch packs. The pressure is held until you manually release the pressure via a solenoid controlled by a remote (and conveniently mounted) button which then converts back to rear wheel drive. An intermediate bleed valve can be inserted and adjusted so that the pressure is released slowly, thereby progressively releasing drive from the front axles. As it's an electronic solenoid releasing the pressure, there is no reason why this couldn't be activated automatically based on a signal from the vehicle speed.

Give me a day and I'll see what I can retrieve back.

Hi Gav ,

hows things ? As you would appreciate this has to be done properly . i have heard of a few chaps doing it very primitively and running into a few problems.

What you have described sounds logical, retrieving the info would be much appreciated. I shall wait .

Thanks for your effort Gav.

I had a problem installing powerfc to my enr33 -- the problem was locked e-ts clutch because of constant 4.5v at tps output pin @powerfc. So give e-ts control unit constant 4.5v at this pin and see if it helps.

Hi stronzo,

there is a little more behind mine than that , do quick search - exXU1 - and attessa, you will see where it's all at .

Thanks for the in put though and i am glad you got yours sorted relatively easy.

What - nobody out there knows ?? Thats surprising! :O

What about running a variable voltage controller on the hydraulic pump...just a thought.

just buy a HKS ETC-EDA it l do exactly what you want.

or buy an Apex'i manual pump lever.

easy

apexi dont make those anymore, tried to order one last year no good. ADVAN in silverwater make one but it doesnt look as nice. I am making one on a wilwood brake pedal and floor mounting it, but I still dont know if it will work how I hope.

Hi Daniel ,

how are you?

Alls good so far with the project - your plate worked fine .

Who are these people who make this , and or have you got your attessa manually operated - if so what is the best way- remember i have no abs and we cant seem to get working correctly - so i we would like to do in another fashion, either set up another electronic way or manually with gauge , any suggestion or links please?

thanks.

Don’t you guys feel like savages, operating the ATTESA in such a crude manor. Gone is the controlling of torque delivery to the front wheels in a nice progressive manor while exiting corners. Your using up all the spares, dragging em up strips :(

M

I have gone the HKS ETC+EDA route, but would be intersted in a manual controller.

Me too! I have had limited luck on attaining info in this area - i am interested in your set up Daniel - if it works of course, maybe if Next time and me order you to make one or get hold of some for us we could get at a reasonable cost. what's your thoughts?

Guys have a look at these, i think i am going to buy one - can't help my self ? http://www.ikeya-f.co.jp/en/car_type/bnr32.html

    • 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.
