K1100 16V Turbo build...now transmission build.

I think going the oil cooler route with built in tank would be the easiest way, but if it was mounted higher than the box would it have a tendency to drain back into the box and not stay full?

Only if a hose is at the bottom, if theyre both at the top the oil cannot drain out

I seriously doubt it!

oil in the oil cooler no matter how much will have no effect on the surge in the sump. If there isn't enough oil in the sump to keep the oil pick up covered you're in trouble, doesn't matter if there is 3 or 4 litres of oil in there. Extra oil in the oil cooler won't help that.

The fact that the gears have taken up more room means that the surge of the oil may still be similar. Reducing the oil quantity a little to compensate like Paul suggests is probibly going to be perfectly adequate

I think as long as there is a 3.5" depth of oil in the sump then surge shouldnt be a problem as the pick up will be well covered

I seriously doubt it!

That's exactly what I'm trying to do Colin. I basically want to keep the same volume of oil in the system, if not increase it slightly but possibly reduce the amount of oil being held in the box too.

Right I see. Will there be any benefits? Or just added compexity?

Colin, Matt has not mentioned surge, even although your comments are obviously valid.

If surge was a problem then the windage tray mentioned earlier might be the answer
(but is there still room with the new gears ?)

If surge is no longer the issue I think Matt was concerned with 1) too high an oil level to allow the crank to turn without aeration and general drag and 2) if the level is reduced will that make the oil get hotter more quickly.

Pauls car seems to survive on less oil, but I have a feeling that a car used hard for more than just a few miles might prefer more oil, so an oil cooler seems to fit the bill, with or without extra capacity.

Now tell me that I am talking out of turn - I know that there are much better informed/more experienced people on here !

Would love to know if there is any chance of some more of these being built?

how about some kind of semi dry sump?
still plenty of run off/spray to lube the gears and linkages and store most of it where the second pump cam take a constant supply from?

say some how get the center pick up to draw oil up and out of the gear box then throw a scavenging pump into the top of a holding tank from the bottom of the tank onto the normal oil pump just like normal and have a vent on top of the tank to the sump to balance/release pressure/over flow you could say have a tank that holds 3 leters and fill the engin with 4 the extra liter being ether still falling to the sump or being circulated lubeing the gearbox

Hi Matt, regarding the oil quantity:
I agree with Paul just to measure first.
Check out on an ordinary gearbox without oilcooler how much oil goes in the box. Realize app. another 3/4 pint of oil will be in oilways and filter.
Then check the same for your box to the same level (which is safe for surging but also no crank slamming the oil.)

I bet it will be maybe a pint less in worst case due to extra submerged parts and some original space missing.
And then add up the volume of an oilcooler (13 row?) and it s hoses. This will compensate the quantity.
It all depends how long and strong you will spank your car later on: oil temperature with normal to sporty street use is maybe even too low when using an oilcooler. I found that out myself and installed a thermostate in the oil cooler hoses. Best decision ever. Good temps at the street and no signs of overheating at trackdays.

ps: what is the quantity of oil between max and min level of the dip stick? I guess more than 1 1/2 pint.

Some incredible work as usual mate! look forward to seeing it on the road again!

Also, i still have that block up the barn if you need it? having a little clear out so its yours if you want it?

I think filling the box up and seeing where the level comes to is the first step. If its too high then I'll modify an oil cooler to have extra storage capacity and work out a way to keep the level lower.

Cheers Dan, yeah it's slowly getting there just the last few bits to do now then it's test time! Yeah I'm still after that block, just give me a shout when your at the barn next and I'll come and collect it. whilst im there i'll give you a kick up the arse to get yours finished.lol

Haha, yeah no worries just let me know when. Doing headlining is not a nice job!

It's been a while since I last updated this...mainly due to lack of pics of anything worth showing. Here's a few of the bits I've been working on.

Air pump is now finished (apart from drilling the final air fitting size,yet to be decided).







And fitted to the block..



New oil drain location sorted. Had to to finish the air pump before knowing if this would fit, luckily it just goes!



I did this a month or so ago...the neutral switch location.



Lots of other little bits are now finished off, and I'm hoping to have my reverse gear ground tomorrow so I can start fitting the reverse gear shaft, and gt on with making the selector cylinder for that....there is finally light at the end of the tunnel! :)

What's the air pump for!

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

For my pneumatic shifter of course. :)

Reverse gear will also be engaged pneumatically too.

You will be running air valves next... Very f1

silly question how dose the air flow/pump throw this i can see that the center rides on the f pump lobe and the spring pushes it back dose it draw some oil up and mix with air then pump it to the shifter device?

it draws its air through the two holes (+ another 2 you can't see in the pic) on the outside of the engine and it blows it out the centre hole of the three you can see. that's the one that will have the air fitting on. the hole on the inside of the flannel air just lubrication/oil drain holes. a little oil may pass by but nothing measurable.

it works out to pump 2.5cc per cam rev so on say 1000rpm idle it'll pump roughly 1250cc per min.

The air pump alone is an amazing bit of thinking/engineering, the rest of the build blows my mind.

nice will it have a one way valve in the system?

http://www.accusump.com/accusump_units.html is this any use to solve the low oil problem?

Thanks, yeah it'll have one pressure regulator inline feeding the reservior tank to limit the pumping pressure to my desired pressure. Probably around 45psi.

Mayo - yeah we use them at work on the old gp cars. Works really well. I hadn't even thought of using one of them...hmm?

Nice turn to arange pneumatic shifting, Matt! Will save you a lot of mechanic links etc. And can be fast. To make the utmost advantage of it, do you consider to use a flatshifter like geartronics (I do..)? In such case I wonder where you would place the rotational transducer.

Talking accusump: this won't enlarge your active oil capacity., but is able to prime the system before cranking and have pressure by oil pump.

have fun! Bart
