Designed in house using CMM technology, 3D modelling and FEA (Finite Element Analysis) to ensure perfect fitment
Maximum torsional stiffness for your highly stressed racing engine whilst minimising weight
Internal draft angles and gutter channel virtually eliminate pooling and vacuum effect from the rotating assembly
ORB style ports thread-milled to maintain high quality surface finish and tight tolerances
Designed for maximum clearance around OEM chassis components
Manufactured from aerospace grade aluminium using multi-axis precision CNC machines
Anodized gloss black for corrosion resistance
Uses grade 10.9 or better hardware

A billet dry sump to suit Nissan VQ35HR / VQ37HR engines – precision design providing maximum torsional stiffness for your highly stressed racing engine whilst minimising weight

Weight 8 kg (17.6lbs)
Dimensions 700 x 300 x 200 mm


Whole system about $5000 AUD about $4,000USD!

Everything is engineered and designed from scratch in house where as other companies are essentially buying kits ie they dont make all their own hardware

They don't have a dry sump for the VQ37VHR??

They certainly do, I funded the prototype ........ which is a part of my engine build .... here

http://www.the370z.com/engine-drivet...ine-build.html

Sump pan is one part of the kit, also contains pump mounting brackets, crank damper and gilmer-drive pulleys, etc etc. Remote oil tank not included.

Just got off the phone with them about 5k aussie for a basic system (a few grand more if you want the whole enchiladas) - exchange rate looks good right now for USD to AUD:tiphat:

Nice looking kit. I'm assuming that it replaces the AC compressor like the Dailey Engineering kit does?

Anymore information about this kit? Does it have an option for a air oil separator and will the ATi dry sump damper work with this kit? Will you lose AC with this kit, summers are brutal here in fl

yes, but he did explain a way where you can keep the AC, they make their own damper i believe.

Im on the website now and all i can see is the damper and the pan. I Don't see an option for the entire kit.

Yeah i told him he needs to update his website - BGTV8 has the system on his VQ40 a few posts above, it has more pictures of the 370z kit.

They mainly do RB motors, 15 in the last 2 months.

Yeah i noticed that. I clicked on BG's link. Guess i'll just have wait to until more info is out about the kit.

Could always go.with mamotorsports dry sump, or wait until phunk comes out with his

I'm sitting here thinking looks like the most important part is the oil pan. Now mind you I'm just now starting to research Drysump's but could one not build there own kit? I found plenary of websites with supplies

Barnes Dry Sump Oil Pump Systems - Circle Track Supply, Inc.

Now of course you need a lot of research like how much pressure you will need to make sure you get the correct size pump and oil tank. But hey it's a start lol

Daily engineering makes a dry sump setup as well. So they do have others out there. Looks good though.

And what's the price point??

Mamotorsports is a Daily's dry sump.

I wouldn't recommend unless you really plan on tracking the car hard or plan on making some serious power( you are going boost:stirthepot:). It's 7 grand minus the AN fittings and lines and you lose your A/C, but that could always be worked around. So at the end of the day you're looking closer to $10,000 for MAM sump. Just giving my unworthy 2 cents

im not currently working on a dry sump. its an idea ive tossed around in the past but currently no project going on with that!

If and when the new z35 comes out. My 370 I will be turning into a strictly track car. I plan on boosting it in the near future. The wife already gave me the green light lol. :driving:

Then i say go for it, Im doing it year after my build. Another alternative is the nismo oil pump, and the rjm oil pump gears. But the rjm gears are still untested.

Yes I was looking at them.. but to me they just seem a bit pricy.. for what they are.

I have them, but not installed as they came just a bit too late for my build. That said, I'm eager to see if someone is able to safely raise the redline with them and run on the track at ~8500 RPM.

We will see, My buddy installed them on his Z but his redline is only to 8k, power drops off after 7,500

My billet gear pumps for the VQ35 are spinning to 8600rpms at 6bar. I have the VQ37 being working on right now. These will be drop in gears with something a little extra. If you guys decide not to go with the dry sump.

How much are you thinking?

Cheaper than a Nismo pump.

cheaper than 750?

Why the draining is on one side only? So does this mean that if I am making a loong opposite of the draining turn where all the oil will be pushed to one side, will the crank whip it in to foam and destroy the engine and/plus the draining tubes go vaccum due to oil being pushed to opposite side?


Just wanting to clarify if this is an Engineering disaster.(or not)

No, afraid not. However you'll still save some compared to the Nismo and get more from our pump, than you would from the Nismo. We worked off a Nismo pump, that's why I know we stepped it up.

Will this pump be tested in real world conditions before released to the market?
How much more do you think it will cost?

Our VQ35DE gears have been out a year now, the 370z gears will be the same material. At 8600rpm we are seeing 6bar of pressure, this is in a race application, no street driving. We'll have some VHR builds running our pumpsite, just waiting on us to release to public. Well the Nismo is $1299 if I remember correctly, so target price will be less than that. That way you get more for your money.

Dry Sump
 

What happens with the OEM oil pump when you go the dry sump route? Does it just stay as is?

Noop, it goes away.

The suction ports are onthe windage side of the engine the crank feeds them. Also it doesnt work quite that way the reserve size of the tank is the most important thing and the pan is definetly not the most important part of the kit its the pump followed by the crank setup, pump mount and drive, and vacuum regulation so you dont instantly destroy all the rotating seals in the engine and score the piston by drying the cylinder walls. Oh and filtration and pressure drop between pump and block oil inlet. The pan could literally be a modified factory pan with with the pickup and lower pan removed and welded off and some -12 bungs welded to the side. Just wouldnt work as efficiently.

A good 4 stage pump is north of $2k and the tanks filters lines and other misc stuff for install will run you another 1500-2000. Also dont forget the 12qt $140 oil changes those hp6a oilfilters aint cheap
