Dry Sumps...

[mattyd]

Hey Guys,

looking, and trying to shop for a dry sump system for a k20, still in a DC5r.
I know ADR/ Pace make a kit for it, however made to fit into a lotus, as do clockwise motion (very sexy piece of metal).
What im looking for is for a DC5R fitment. Does anyone know of anyone who has fitted one of these kits, seen one of these kits, know anything about these kits other than that they are made to fit the K20.... trying to get an email with measurements out of ADR is akin to banging ones head against a wall
or any custom set ups that have been made?

any help greatly apprieciated and rewarded with praise + worship

EDIT---------

Sump is here, ready for install, happening 23/03/09!

Pretty sure Toda does it

ive only seen it for s2000... ive already spent enough on their parts... i dont have 15 grand to spend on a dry sump system from them now... =S

Are you sure the Clockwise Motion setup won't fit in a DC5? There is a bit of room around the sump I would have thought. What will get in the way?

Why do you want a dry sump?

Pic to pretty up the thread:

thanks charger, its a work of art.. i drool everytime i look at it.

im more concerned with the fitment of the supplied pump, gears, belts... i mean ive got a fabricator if it doesnt fit, but for the sort of money the clockwise one commands, i want it to be a bolt on affair....

dry sump for no worries about cavitation when spinning the engine above 9k.
not to dethrown the k20, but after creating a mega buck engine.. i dont want it to let go due to its inadequate oiling system....

plus i just dont trust oil pumps that spin at 14,000 rpm when the engine is spinning at 8750 rpm.

Good reasons . It might be worth checking out k20a.org as the guys there are experienced at maximising the oil systems of K series at high revs without going to a dry sump.

if ur scared about the oil pump, u should fit an s2000 oil pump as that is designed to work at 9000rpm.

there are mods u need to do.. and that can be found on k20a.org

update, well i ordered the adr dry sump system, as it is the only one that bolts to the exhaust side of the engine.. so there is no relocation of water pump, alt, air con.. blah blah..

we looked into the replacement of the oil pump with the f20 pump, and while being only slightly cheaper parts wise, the labour involved is the same, and the results from the dry sump well out weigh the wet sump.

i dont understand the hesitation on clubrsx/k20a.ord/ here to fit dry sumps to hard tuned engines... i know of the classing restrictions for racing in the states, but to me a dry sump is almost a god send on the track, no matter what car, configural layout, or driving style... am i missing the point somewhere?

mayb because not many people understand how dry sump works?

also, people like brands... branded stuff markets their baffle sump and that's what people buy... not to mention, it's easier to install as well...

how much is dry sump and how does it work?

[mattyd]

lol... i get what you mean about being a brandwhore... lol, and not to diss hondas, because i own and love mine, its almost like we are accepting that there is limited power to be made with them, so we go for the next best bragging rights, deck it out ballin in full mugen or j's racing or amuse... lol im kidding people.

Dry sumps are like a source of constant oil pressure, driven by an external oil pump, and the oil is stored in a tank, not in the bottom of the engine. So starvation during corners, bubbles/ foam forming in the oil become somewhat non existent.

Basically, and i will use a 3 stage pump as an example, there is 2 scavage points on a newly cast/ fabricated sump, which is much smaller than your original wet sump. The oil pump now sucks all the oil that gets to the sump through the scavage points, and back into the tank, while feeding new oil from the tank to where you screw on your oil filter. The sucking creates a vacum, and the benefits of this vacum is that there is no oil entering the combustion chamber, better ring seal, no blow by.

Now the oil entering the engine is entering at a constant oil pressure from the pump, and is coating the parts thinly, and then is being sucked off by the vaccum, creating a better lubrication system. Another benefit of this is you can adjust the external pump to run higher oil pressure, which is good for high duration cams, lower rod bearing tolerences ( ie, you can maintain "looser" bearings, jack them up with oil pressure and run 30 pounds of boost in a turbo car, for exaggerated example)

there are heaps of benefits for running a dry sump other than what i have mentioned

the cons, well they weigh more....

price, well the price of the system i have ordered is about $2200 without lines, or a tank or breather. Price can go up to upwards of $7k, it just depends on what you want, need, and engine.

when you put the price of what i paid next to a new oil pump/ modified pump/ new oil pan/ easy $1200, for $1000 more i have a much more reliable system not suceptable to high g cornering, better ring seal and higher oil pressure/ cooler oil.

You're not wrong there I do taht too ahhahaha...

Understand completely where you comin from... and nice little summarized info on how it works

What are you planning to do with your car btw?

great info

WHAT?!! There is more to life than just mugen? oh noes...

...someone stop mugenbox23 from jumping off the cliff!

Unfortunately dry sump kits are quite expensive, which is probably part of the reason why most people don't opt for one. Another reason would be because their engines aren't hardcore and won't need anything beyond a baffled sump which has been proven to suppress oil starvation by the folk over in JDMland.

Congrats on the purchase - care to do a review on it? And now that your reviewing the dry sump, how about a build thread on your car? You've definitely taken an interesting route and would love to read more about it

What about a oil actuator?

Planning on revving pass 10 000rpm?
