External Oil Pump - Single-Stage Wet Sump In Ac Compressor Location


Recommended Posts

hi everyone, I am starting to mockup a single stage external oil pump (wet sump) on my RB26. using a Ross or ATI crank pulley and thinking to use a Petersen single stage wet sump pulling from stock pickup and pressurizing the factory location on the block (not a big fan of moroso)

Curious who else has done this and if you have any photos or ideas. thanks

Single stage pump isn't anything new. It been done a million times over.

I have been doing them in kit forms for years, aviad single stage pump, 6061 alloy bracket, balancer, drive mandrels etc.

Now doing a surge tank type setup using a two stage pump to eliminate the oil surge aspect of running a wet sump/external pump arrangement.

thanks Brad, i searched but did not see anybody making a kit, I am sure this is not new but I have only 4 weeks until my next race and trying to work something simple without going drysump. we are definitely not interested to develop or sell these or be a competitor to you- just need to get my race car going...We can machine and fabricate the items, just want to have a solid plan together and not have to do things twice. would you mind posting some photos of your kit? do you sell parts/pieces or only the complete setup? also if you could elaborate on the oil surge, thank you

The single stage setup looks the same as this but only one stage on the pump obviously.

These photos are of the "surge tank"system.

Imagine a fuel system setup with an external surge tank. However using oil. The front scavenger stage acts like the lift pump in the fuel tank, and the rear pressure stage acts like the external pressure pump.

The tank has some airation baffles and things going on inside, it obviously returns back the sump same as a fuel surge tank does.

Geoff pretty sure aviaid or dry sump.com do a full rb26 kit (maybe an external kit too), they are not on the site but are listed somewhere... just cant find it atm,

i just got a full AVIAID dry sump kit (3 stage) with largest tank, cast sump (billet avail), ati balancer and drive, breather / separator all fittings etc for about the same price as decent wet pump and large capacity sump here in aus..... 12 day from order in cali to delivery here in aus... awesome.

Honestly any serious 26 i do again will have one of their kits. Speak to john schwarz @ AVIAID in chatsworth California, see what they have avail.

Mazworx get all their sumps and parts via ARE http://www.drysump.com/index1.htm which also do some nice gear.

Hi

    • Took a little trip  went to nismo hoping the get my fuel tank hoses and unfortunately they told me they didn’t have stock luckily I was able to go to a Nissan parts store and they were able to order them in for me  then can home and cleaned the tank with some degreaser and fitted the new hoses before putting it back in the car 
    • 100% I’ll hack into the 33. Strap a turbo onto the RB25DE and/or put the 25 head on a 30 block. 33 passed in cos the reserve was too high. I’ll try lowballing it again and negotiate. Aim is to have it landed and on the road for under 15k, then spend the same amount on top in mods.
    • It's generally best practise to run 1x run without VCT enabled, then 1x run enabled till redline. Overlay the two torque graphs and you'll find the desired RPM to turn off VCT. Sometimes, it might be even worthwhile turning off VCT earlier control torque/cylinder pressure and using VCT purely to spool the turbo.
    • They sell them in Malaysia for about $4
    • First time I ever have issues with Amazon, but my wife often tells me to keep an eye out for fakes. It finally got me. I wrapped up the conversation with Gates. The gentlemen I was talking to seemed to hate his job but the response time on their technical support is outstanding. He stated that the hose is marked with some variation of "SAE J30R10" but that if you only purchase a 1 foot length like I did, it is possible to get a cut between markings and have a blank hose. To no ones surprise, he stated the swelling and "gummyness" isn't normal and to replace/buy from somewhere else (He mentioned NAPA). I'll toss a small end of the new one in gas for a few days before pulling the hanger out again, just to be safe.  Hose should arrive Monday. For those running multiple pump in tank hangers, you know the joys of getting them out and back in. I'm surprised I haven't destroyed my level float yet.  Lastly once I wrap all of this up, I'm planning on hitting the dyno again in 2 weeks while I'm on vacation. I realized recently that my VCT is set to turn off at 5000RPM. I'm surprised it wasn't increased while I was on the dyno last. I'm expecting I can increase it to ~6500RPM, if not more. Should hopefully get another 15-20kw out of it. I also want him to revisit my knock thresholds. I'm occasionally getting false knock around 3000rpm.
