Dry sump tank in trunk?

[Greg from Aus]

High Guy's, I am thinking of putting my dry sump tank in the trunk of my 69.

I am looking fo the pro's and con's

I've not done it in a car but I've had the tank behind the cab of a truck. The additional oil volume can help keep temps down if needed.

On the downside, it could prove to be the source of a mess during oil changes or you run into issues.

Thanks, Is there any pressure loss from the longer piping?

It would penetrate the trunk floor so, an oil change wouldn't be a problem.

We didn't witness any, but you need to insure your hose is sized appropriately.
The oil pressure is created by one (or more) of your oil pump stages. The rest pull a vacuum on the motor and return the oil to the tank. All that being said, the tank itself isn't under much pressure.

Edit: Full disclosure, this was in a 4x4 modified pulling truck, not a street car, so I can't answer to how corners may effect this setup.

[Motorcitydak]

The line(s) going from the bottom of the tank to the oil pump will be under suction. Make sure that the hose you use for that cannot be collapsed. I would not suggest using a regular rubber hose for that. Maybe braided or something similar

The Corvette Racing team puts their sump tanks in the back of their cars so it seems like something that has more pro's than con's if you do it right. I placed my 3qt Accusump in the back of my ride and noticed very little pressure drop. Not quite the same of course, but some of the same principles.

I'm surprised that nobody else here has put a dry sump in the trunk. I've been thinking a lot about where I want to mount my tank. I keep coming back to the thought of weight bias and the effect of moving a couple of gallons of fluid 6 to 8 ft to the rear.

Why not :question:

Im doing my tank in the bed of my truck,

1" ID SS tube under the cab single feed and dual return. 5 gallon petersons tank.

roughly 6ft of line both ways in total. the circle track guys do this all the time and have no issues.

That's what I was thinking.

Greg - I was so big on this a few weeks ago. Spoke to Jason @ Katech, Gary @ ARE and Bill @ Aviad. I also posted a thread on 'Tech and got some good opinions. My situation was maybe a bit different as I already had a ported LS9 pump, Peterson tank and baffled pan. None of which I was relishing swapping out. BTW, (FET) Mike Maier is running a tank in the trunk and Brian H was very helpful in showing me the set up.

General concensus with the experts was it could be done w the factory pump and tank, but would probably need -16 feed/return. ARE suggested I use their pan...:D

Here's what killed it for me. First, I can't reconcile how a -16 return gets fully utilized when my thermostat, cooler and other parts use -12 and smaller? I kinda thought that must defeat the purpose, or at least create a fluid bottle neck. Second, have you priced -16 XRP fittings? One bulkhead pass through needed four, maybe eight ($800). I didn't price it out completely, but I figured I had $1200 or more in fittings for those two lines. Third, packaging it on my car was another fab item to add to the list. Take my word for it, we eyeballed it front to back and there's trunk work, pass throughs to ensure the lines are not the lowest thing on the car, and possibly subframe mods to get it to the pan. That's getting old w a painted/powdercoated car, and I've still got a long list to complete; I want to get my car on the road at this point so it was a question of priorities. Fourth, thank Hollywood for this, even w a firewall you're putting flammable fluids in the passenger compartment of a car that will see street time. Carl and I both agree (you guys may not) that even though there would be a firewall separation, the trunk is part of the passenger compartment. Fifth, everyone I spoke said there was no significant front end penalty with tank up there. Lastly, I'm not building a max effort race car. My car is a street car that will be track capable. It may see more track time than street time, but it would certainly be a different animal if it was track only. I don't know how to better explain this, but putting the tank in the trunk would violate the theme of the car. I could go further on this point but this is already the longest post in Lat G history...:cheers:

I'm with Ron, it seems like a lot of expense and effort for no REAL gain in performance. This isn't Nascar guys. Sure you save a few lbs on the front end but you are adding more than a few to the overall. Also, your adding capacity and that means you really need more pump. Mike Maier is running a Nascar Nationwide engine. They likely have the dry sump in some low perfect place and an oil pump that would bilge the titanic.

Chris, I have to diagree with you on the similarity on the accumulator. It's a lot different in my mind.

Todd, I think Mike actually has the dry sump in the trunk of his car now. I think I spied it there over the weekend at Del Mar.

My friends dry sump set up. Street legal car but will see mostly track time

seriously who doesn't like a little extra junk in the trunk? :D

[SuperB70]

Here in Europe we have been putting tanks in the trunk for decades. Normal place in rally- and track cars.

In your case, how about useing hard line in next to fuel lines inthe chassic?

Another pro's is that more oil, loner time to get hot and will last longer good.

Hard to argue with the likes of Hannu Mikkola, Juha Kankkunen, Tommi Mäkinen or Marcus Grönholm.... :bow:

LOL:rofl: Our names are little different...

But we arent only winners in rallying.

European GT Champions with Orteca Vipers, Audi factory race cars and so on...

Kimis performance todays race was also great. Only if he had different tire strategy.

We also hold many NHRA drag racing world records :thumbsup:

:wow: :wow: WRC those guys are race car drivers. :wow: :wow:

It hurts to admit but it's a French guy who has a mortal lock on that series. And with French cars :rolleyes:

It's ok you're a Chevy guy they've never won there. :rofl:

[SuperB70]

There is nothing bad to say about Mr. Loed than he will be in historybook.
He is the King. I humbly take my hat off. :hail:

Great example what you get when first class driver gets to develop a car from beginning. Has done that with every Citroens WRC-model.

Same happend with Makinen and Mitsubishi Evos.

French car? Well they are race cars, a global product.
I'll bet that not all parts have PSA (Peugeot Citroen Group) logo on them

The day that Chevy wins a carmakers World Championship in WRC, I'll burn my Ford and Mopars and tattoo a bowtie to my forhead.:wow:

Well I can beat that winning record still with a couple Finns:

7- and 11-time World Enduro Champions Kari Tiainen and Juha Salminen.

Salminen has cleaned the table also in US...

Hey pal I drive a Ford daily. Not sure I should admit it. :_paranoid

That's different. You need that to be dependable. :D

Half the fun in this sport is tinkering so your Chevy is probably the right choice for that :rofl:

I think you're cars are safe. How about some updated pics of your Bee? :woot:

[SuperB70]

This is little OT but many thing is different here.

Like a Watt link. It has been used in rallycars from to early '70.
Sometimes I wonder some writings in here, like use of aftermarket ECU.
We dont reprogram/flash or chip our stockones, just remove them and put on a shell. We use things like KMS, Motec, Autronic, Cosworth, MegaQ ans so on...

Much more sophisticated than Accel, Holley and Fast. But I think it's about where its made to you guyes...

With all due respect.

[SuperB70]

There is nothing happening, thanks for asking...
I'm building a '68 Charger with 572 Hemi + 4.2L Kenne Bell.

Maeby you have read my thread about it in Forced Ind-section.

Its coming nicely, should be starting in this or next week. Then opening my on business so will see do I ever get to start my own car.

I did get some parts for my engine. Another crank, forged H-rods and custom JE's. So I can put unused Competition Coupe stuff on a shell.
Have made own custom billet main caps and last but not least I bought my self one those Kenne Bells Liqued cooled 4.2L blowers. Supports up to 1400Hp
