Well I already have an extended sump. I was wondering if I should run a accusump oil accumulator. After reading up on it a bit. I slowly started to understand how it works.

The way it works. I dont think you would even need a larger sump for that matter

In the event you lose oil pressure for a split moment the accumulator would take care of it until oil pressure is returned. Well for any where from 15 to 60 seconds.

Has anyone used them before.

The car im building is for around 800hp the very most. And only for drag racing.

The oil accumulator can even be used for pre oiling before start up. Cost wise I dont even see a need for a extended sump really.

Any thoughts would be very appreciated.

We have a 9 liter sump and will be using one also.

You can never be too careful when it come to maitaining oil pressure, all you need is that one time you kept the revs up and pooled oil into the head to run the sump dry or high g forces to move the oil around and uncover the pickup.

Its good insurance.

This R33 GTR build includes an extended sump, (same as yours I believe) HKS oil pump, oil restrictors and accusump. I'll find the page for you (although the whole thread is interesting) ...its page 47, post #701 and on the next page post #713 there is a link (reproduced below) that he made on the operation of his accusump.

If ONLY drag racing with no high G corners then not worth the effort cost wieght etc

Extended baffled sump will be enough

Edit, your running rwd with slicks yeah, get the Accusump cuase once those front wheels get airborne all bets are off

If drag racing the design of the frontal sump setup is working against you, on hard launches oil will move to the rear when you need it forward.

Even gated and higher capacity is no guarantee that enough oil will remain over the pickup for long enough, most of the top level of oil will try to go over the baffel towards the rear.

A hard 4WD drag launch on sticky rubber is heaps of g force.

Idealy the sump should have been designed on the rear.

We have a freind with a drag racing Supra that logs oil pressure, on the launch and next 2 gear changes logs recorded the oil pressure dropping to zero before he woke up to what was happening......

As I said above, slicks is a different ball game, I checked the data logging on my 34 after a trip to the drags with Toyo TQs and I had no oil pressure issues

There is so many variables you can not really compair two different engine setups

We are the manufacturer of the Accusump, we always recommend looking into a better oil pan first. With that said, a front sump in a drag racer is a recipe for disaster and I personally would jump into an Accusump right away. The front sump oil pan will be working against your oiling system almost immediately. Our best dealer for New Zealand is a company called Demon Tweaks. Their website is www.demon-tweaks.co.uk.

Never heard of Demon Tweaks and the UK is about 12,000 miles away - the US is closer. Accusump from Canton is available from a number of speed shops in NZ but the one that comes to mind first is Cardwell Racing. I presume there will be a number of suppliers in Australia as well.

From what I hear its a bit more expensive to do a tune up. Well that also depends on the accumulator size your going to use. Like he said above on a oil change discharge it and the oil capacity of the accumulator is the additional amount of oil you will add to your sump. Start the motor up close the valve to the accumulator after about 1 minute of running. Check your oil level with the valve close with engine off. If all is good. There ya have it.

They only con I see to have this part is the space it takes up.

I rattled my brain as to where to mount this part. I may end up taking out the ac condensor and mount it round that area. Right behind the hood latch and on top of the intercooler.

    • Have a vb in honour of the car comming back
    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
