Replacement non leeking Alloy Powersteering Tank
Discussion
Be careful, I have been told this isn't straight forward, the tank needs to separate any air bubbles and cope with the oil expanding when it warms up. someone needs to see if the tank you are proposing actually does the job before lots of owners rush out and buy them.
The reason no one has changed the ZF one on the later cars is that a better one has not been forthcoming, I have been advised by two fabricators to leave well alone.

Ive run this tank for over 3 years now reving to over 8000rpm on track and running over 600bhp the entire time and not had even the smallest leak or cavitation... it works and is proven on my car.
It is not just a little tank, it has baffles we designed to remove the air from the oil, without these properly deigned the oil would cavitate and be noisy and leak on track.
It will be a copy of mine in internal design but made so it can fit in place of original, it won't have the angle cut out like mine.
Ironically Im actually planning to remake mine over the next year... in carbon

No offence guys but if you want it tested properly, your going to need to fit it to my car for a track test day, which regularly registers over 1.5G on the vbox. The problem is heat and high cornering loads for prolonged lengths of time and that won't be properly tested on a car with road tyres and low cornering speeds just doing a few laps or fast country roads. Even the fast track day cars won't be a suitable test for it in my opinion, it needs a proper kicking to be deemed a true fix.
I'm happy to test it and would buy one if it works, I'd think a larger top half of the reservoir needs added to allow more expansion room above the baffles though but that's just an assumption I've made.

I believe you are the only person running on slicks?...... remember people are having issues with the stock one leaking fluid on fast road drives with normal tyres.... this one is already much larger volume than the stock M400 one and has better baffling hence it doesn't leak on my car. I designed it for fast road and track use.I'm happy to test it and would buy one if it works, I'd think a larger top half of the reservoir needs added to allow more expansion room above the baffles though but that's just an assumption I've made.
I hate selling stuff or getting involved with selling bits, however I was beaten into submission by Pete who really wants one and considers the 4 years on my car a good enough test for him.... make your own mind up and let Pete know.
True its the only car on slicks just now BUT surely that's the whole point in testing something, someone quicker than you on road tyres may well push the system to leak where it hasn't on your car, Whereas if its tested on slicks at the limit we would know that its fit for any purpose up to that level of abuse... lets face it, your car hasn't done that many miles at speed on track days, your always to busy playing with lap tops... 
impressive effort to get a free one Graham
I developed this for my car not your racer and i have no need to put any of my developments on your car before mine to test them, If your happy with your stock one leaking then stick with it or pay to get one developed, Personally I don't care as i already have one which never leaks.

Effort to get a free one? Haha you are mistaken. I couldn't give a monkeys about getting a free PAS tank, If you read my earlier post properly I said I will test it out for Pete and then PAY for one... As I'm paying to replace and upgrade half the parts on my car this winter, I'm sure a wee tank won't be a problem. Until an upgrade is available, my iron-bru bottle catches the overspill just fine.
Yes the tank works for you, great but your missing the point and taking this to heart, but in fact you even admit the tank will be different to yours.
I'm simply trying to help make sure a product doesn't go to market and get fitted to cars badged as a fix which actually hasn't been tested properly, then the manufacturer and Pete end up dealing with unhappy group buy members when it turns out to still leak.
Chill oot man

Come on graham I know full well your loaded and wouldn't skimp on silly stuff like this, I was trying to make light of you claiming any testing other than on your car was a waste of time, especially on mine as I'm sooooo slow....

And I think your missing the point Graham if you believe its the corning g's that cause your fluid to leak, its the sustained rpm which is an area that my car tests harder than yours?
The tank will be different to mine as mine won't fit a twin turbo car as I relocated mine so I could have a larger air filter... it a location change.
Im still very surprised that you of all people are so anti sorting an issue that you suffer badly with... i mean its very important in a race car to keep the fluids (especially oil) in the right place if you want reliability to finish races and be consistently fast.
As for taking it to heart... As you know Ive developed most of the stuff on my car myself, stuff thats very different to what others run... so what you are doing is a bit like me picking apart your racing.
