Alternator output. We don't want to change away from a stock cup alternator but in an endurance car where for night use you'll have 6 X HID's, Apex lights, regular cooling fan action etc. etc. on the go we just don't have the amps for it in the alternator. Electro-Hydraulic PAS is great for sprint and road car use but not so good for endurance, even with no load but the pump running it pulls around 13AMPS and can peak at 60AMPS draw when loaded heavily.
The ideal solution is EPAS where a motor assists the coloumn directly. This has zero draw in the neutral position and only draws as assistance is applied. It's what we use on the Mosler etc. and is lovely but a couple of K to put in there so a pricey option!
I don't think so for now Kenny, I think we will see if it can work successfully without so we will increase the tank size and I will ask Matt about some more heat shielding then give it some stick at Donington with long runs and see how it holds up. We will keep a close eye on the temps and if it is then a recurring problem then we will have a look at possible rectifications I think as you say the oil cooler will be the best way to go but I don't want to put one on unless it needs one ThanksAre you going to fit a cooler aswell?
The extra capacity will obviously help but I would have my doubts if it will totally cure the issue, might just last a little while longer before it overheats.
Given the cars intended use I would put a small oil cooler in there, if packaged neatly (as is the rest of the car) the weight increase will be negligible and will give you peace of mind that it's not going to cause an issue in future.
The pump itself is more than capable of pretty much anything you care to throw at it, as long as the fluid is kept at a sensible temperature. The other thing that may be worth considering is an underdriven pulley for the pump, not looked into it on these cars but if the engine spends most of it's time at 7k rpm+ the pump will be working harder than it needs to, therefor pumping more fluid round and putting more heat into it which quickly becomes it's downfall.
Thanks for the drift works recommendation I have just had a look and seems like a decent kitCan you fit a bigger pulley to the PAS pump to underdrive it ? that ought to take some heat out ? PAS fuild cooler kit from driftworks would also be easy to adapt to fit, save buying all the bits seperately.
I didn't realise that it didn't have any cooler as standard which as you say probably explains the issue, Yes I think I saw this pipe at the weekend so I know which you mean and it is in a fairly vulnerable place for taking heat in.I appreciate you don't want to be adding stuff to the car if it's not 100% needed but given past experience most hydraulic power steering systems need some form of cooler, even as standard most cars have something to help get some heat out of the fluid, I was quite surprised to find the Clio doesnt really have anything which may explain why people who track them have issues with the pump and or ultimately the rack.
On road cars it's quite common just to have a simple loop of aluminium tube on the return line from the rack, normally sits infront of the radiator or along the edge of the subframe, might not seem significant but even something like that can be enough to keep temps under control.
A section of the feed line to the pump on a clio is ally but it's not going to see much in the way of cool air to do anything, infact it's going to get hot air off the rad!
If the car is getting used on track for anymore than 15-20 mins at a time I would say some sort of power steering cooler was advisable, increasing the capacity of the system will help but if there's no way to get the heat out, you're just delaying the inevitable. D
I dont want to sound or come across as being negative, just what I've gained over the years, your car is very nicely put together and as I said previously I wish you all the best with it, just trying to save you some time and help you get it ready soon as.
Kenny.
Thanks mate, I have no issues with using used parts so could be an optionCorsa B electric column is readily available secondhand for under a 100 quid and the controllers for them can be had very cheaply if you just go for a basic one.
Obviously there is a cost of fabrication time to fit though, and wether you are happy with secondhand parts, so might not be relevant to this particular build but just thought I'd throw into the mix as different options were being discussed.
Yes I see what your saying Kenny and will have a good look into it and work out with Matt what to do. The kit that was mentioned on driftworks was only £60 odd so pretty cheap solution if it will do the job Thanks againIf its not going to cost you much to fit a bigger reservoir then I dont suppose it can hurt to try it and see but a cooler would be a fit and forget solution. There's nothing worse than having something like this ruin a weekend and cost you a potential points scoring result, £50-60 for the cooler, a few fittings and some hose, all in probably cost you £150 tops depending on what hoses etc you use.

TDF have a great deal of experience in running these clios so whatever solution they come up with I'm sure it will meet the high standards that the rest of the car is at.

various bits of loom and stock when i was up there last,
by now??? probably a selection of destroyed gearboxes from Matts car and a sleeping bag for Al....... haha

Bloody JC5s
Savage but ££
Corsa B column is a no go on an endurance car with hot sticky slicks and lots of steering action. The motor just isn't big enough and you get to the point of thermal related failures (or thermal shut down if you still have the stock EPAS ECU) after a relatively short time running. Been there, tried that, have the data
Yes Ive noticed the C stuff looks a bit more manly but not tried it yet myself, well other than driving standard corsa c's with it, lolCorsa C column is better (bigger wheels etc. etc. as standard) but still not quite man enough. The DC system is very good and actually contains some corsa bits but the gearbox is totally different, controller allows big amp initials etc. and the motor has a big, big heatsink!
I'll have a tenner on it now big tank with an internal deaerator and it'll be absolute mustard
Yes it certainly looks the part I know what you mean about the dyno floor it looks soft in the pictures but is surprisingly hard! Still I suppose its softer than concrete lolyeah, the office looks miles better... and the area above the dyno cell frees up/creates a lot of room now... as for the new flooring in the dyno cell, well, it looks nicer but i think Spanky`s knees might not like it after a RR day on strapping duties hahaha
Duplex penthouse with mezzanine IIRClol. Room with a view
Do it Matt and then I can steal it when you get bored Talking of stealing I still owe you a wiper arm!I can almost justify a Sadev on the basis of massively reducing TDF internal labour charges
