Engine Power GAINS With MORE Reliability? How! [TECH TALK]

What do you know about dry sump systems? What kind of power increase might you expect to get on your LS swap or Chevy LS engine with the fitment of a dry sump?
Due to reduced windage losses and increased pressure differentials across the piston rings a dry sump system can not only provide increased reliability due to a constant supply regardless of the g-forces on the engine, but also a slight power increase as Bill Dailey from Dailey Engineering explains to Andre at the 2018 Performance Racing Industry Trade Show.
Discussed is how the vacuum is controlled, some of the potential gains you might expect from an LS crate motor and others depending on your ring tension and also how monitoring this vacuum and the pumps performance can also give an indication of your engines overall health. Lastly Bill covers some of the factors that go into deciding, or even dictating, how many scavenge stages you might expect to use on an engine.

Gain 30 horsepowers and 50 brainpowers with your own HPA branded nipple covers. We've added extra material so that they look just like a regular t-shirt - bit.ly/MerchHPA - Taz 👨🏻

[@Technoflicks]

nipple covers with extra material, is that an original joke? That's brilliant if you made that yourself

[@hpa101]

@@Technoflicks cheers! I didn't have to look it up but it's hard to claim you're ever the first person to think of a joke. I'll take the compliment though. I try and come up with a new one most weeks for a bit of a laugh =) - Taz.

[@motoray69]

They do cover my nipples quite effectively! Now i need a banner for in my garage..... hint hint.

[@Technoflicks]

@@hpa101 I agree, it is hard to claim whether or not you've created a joke. Usually what I say is that I came up with the joke organically or on my own.

This is how 95% of Andre's interviews go: Andre: "What are the benefits of this product?" Guest: "Well E=MC2 and a+b+c=d and blah blah" Andre: "Let's take a few steps back because we need to explain it as 1+1 and 2x2." Thank you Andre for always translating full propeller head into English. 👍

[@ZIAD2122]

It really just shows off his intelligence. I've always believed if you can not explain something in its simplest form you dont truly understand it.

[@AutoBodyEverything]

Eh yea that’s true but.. remember they are obvious questions to provoke obvious answers. Not everyone knows what to ask and sometimes they don’t ask the correct questions. Sometimes in these interviews they will also ask stupid questions bcs you never know what types of questions ppl may have and are afraid to ask.

[@MafiaboysWorld]

@@dogmoo Yeah, it slightly changes each time, I've heard him use both. 👍

[@TheEsseboy]

@@ZIAD2122 Some people are inherently bad at explaining things, they've come up with their own way of understanding things which builds on what they already know and there for are not understandable by people who are not well walked in the field. And when they talk with fellow engineers they tend to talk as efficiently as possible (i.e shortening their desciption is much as possible) so they use fancy terms not everyone is familiar with. And they totally skip over explaining things that every other engineer knows because of their understanding of physics. As a person studying engineering I most often understand what they are saying without Andre's questions, but some things are left out by the engineer, which is common knowledge to those understanding physics, hence Andre can make it understandable to everyone :)

HPA = best automotive tech interviews around.

[@Precisionhack]

These Engine Tech vids give me a high pressure differential in my pants

[@johngregory4801]

Tog Gun reference from the cockpit of Wolfman and Hollywood included.

[@lockjawjak]

Outstanding video as usual, been looking for a dry sump video as detailed as this for a long time

[@HalferLandPerformance]

GOD I LOVE THE DETAILS OF YOUR VIDEOS!! It will go over a BUNCH of peoples heads, but if you listen you learn a lot in each video!

[@hpa101]

Thanks mate! Glad you enjoy the content and cheers for the kind words :) - Taz.

[@Euphoria0011]

Didn't even know that dry sumps created vacuum and reduced blowby, thats badass!

[@JustForRita]

This gives me more ammo to throw at my engine builder regarding my dry sump setup 😂

[@ZIAD2122]

These guys make awesome videos. Awesome questions and the interviewer actually understands what's going on. A+

"when it comes to..." "as we've seen..." *raises volume to 100%*

[@JuanAntonEgo]

D@mn! That was some great tech. Info.i was thinking on runing a Dailey dry dump system in my future engine build.Thank u HPA for making this possible 😀

[@hpa101]

Thanks for watching Juan! - Taz.

[@NieJestemzPolskiPL]

Another great tech talk, pleasure to watch : )

[@ther1kid]

Fantastic interview. They both did a great job.

[@The_StreetSweeper]

I’m running one of these on my street car..427 LSx with Twin 88’s, mine is a Dailey Engineering 7 stage Dry sump with the turbo scavenge section. It is a VERY nice price and well worth the money!!!

[@bigredracer7848]

Thanks for taking the time for us

Thanks for taking the time to watch and comment, appreciate it :) - Taz.

[@gordowg1wg145]

Another excellent interview - I especially liked the way you got the chap to elaborate some points further! :-) 2:20, somewhat amused by that as it was exactly what some F1 teams were doing before they got caught - different circumstances, though, as that was to use it as fuel to circumvent the limited 'official' fuel they were allowed to use. Perhaps of more concern might be the oil lowering the detonation resistance of the fuel used? With the wrist pins (AKA gudgeon or piston) I would suspect it may be more an issue of their lubrication normally being by oil splash, or mist, and without oil squirters, or drilled connecting rods and forced lubrication, they may simply run dry? With most piston skirt designs, especially slipper, the pins would appear to be well clear of any 'blowby' combustion gases which would be very low in a well built engine, anyway? As the chap said, there are teflon/low drag seals available for most engines, many are double lipped to provide optimum protection against leakage - an old-school thing, if you are caught short or cannot find some, is to install the seal backwards ( I would recommend it be well lubricated on initial instal, though). One thing I was hoping might be mentioned with the vacuum level, is the need to have airflow through the crankcase as that is what carries the oil to the pump. By that I mean the pressure difference in the various parts of the crankcase move the oil, droplets and oil mist to the lowest pressure area, the pump(s) inlet(s) and through the pump to the reservoir. Perhaps the best way to illustrate that is with a straw in a drink - with the straw end open it is easy to suck the drink through but if you close off the end it doesn't matter how hard you suck the drink will stay in the straw until you start opening up the end and, how much you open up the end will control the speed the drink moves in the straw and/or how hard you have to suck to move it. Same principle applies with the dry sump - you have to balance the airflow at the desired vacuum to make sure the pumps can actually move the oil through fast enough - IIRC, the rough figure is 80-90% air and 10-20% oil. As an aside, some pump manufacturers will have options for other components to be driven off the back of the pump stack, like power steering pumps for Sprint Cars - might be worth enquiring about for those chaps who have packaging problems or want to tidy up the engine compartment. Oh, and external adjustment makes setting oil pressure a piece of cake.

Steve Dinan said this on a Podcast i watched a while back, I like it!!!

That was awesome, subscribed

[@tdlaustralia7791]

Interesting conversation as usual.

[@brianbob7514]

great video, love the no nonsense content.

[@davidciesielski8251]

Well done

[@panchonorthmann6408]

No mention of Dailey's awesome air/oil separator? I've had a chat or two with Bill. He's actually pretty good at breaking down the intimidating subject matter of oiling, windage, etc. Good guy.

[@dj4monie]

There some good systems available. Radium has a two can, two stage system for the Focus ST that I will be running. Mountune offers a dry stump system for the Ecoboost 2.0/2.3L engine but for $10,000 I don't think I'll need that just yet.

[@DanielOrtegoUSA]

I have a Noonan LS Edge 427, and I'm hoping to have Daily to configure a custom system/pan to fit the Noonan block.

[@Euphoria0011]

looking at one of these for my ej257... :3

[@cscustoms7625]

I know this man is so much more intelligent about complex engine designs and performance. One thing bothers me. A motor is a motor and an engine is an engine very big difference! 😔 I hate my teacher 👨‍🏫 for drilling this into my head but dang... love the videos guys and this is killer information. I really like the way you break it down and bring it back to earth with example applications and such.

[@heavymechandelectrical]

I work on mostly diesel and may gas never considered crankcase pressure as a product of leaks and that's just my ignorance always learning thanks guys let alone turbos damn

[@moondo60]

Your Castings are undoubtedly the best real performance engine engineering and development items on the entire web. I think you very kindly for the specific drill down type questions in a higher level of Engine developers that you interview thousand thanks

[@hpa101]

Cheers for the love E D H! Glad you're enjoying our style. We've got some awesome stuff coming up from Goodwood and there will be a bit of old F1 engine tech in there for you too so make sure you've subbed. First one drops in a bit under 24 hours =) - Taz.

[@Morphasella]

what is the teflon/ silicone piston ring he is talking about?

[@omarreyes8722]

Oh yeah this is gonna be a good one 😁😁🍿🍿

[@mikeruthen6236]

Would've liked to hear a little more about turbo scavenge section though..

[@hpa101]

Do you have a specific question? It might be answered somewhere else, let us know - Taz.

[@canadianmarauder1923]

Very cool. Lots of advantages but I don’t drive a race car. Gathering parts to do an Eaton swap on a 32v 4.6 ford but this is probably overkill.

[@dj4monie]

This is overkill for many situations, but so are running surge tanks and three high power EFI fuel pumps but that is quickly becoming normalized since running E85 is getting more popular all the time.

[@powerst33r]

Wouldn't more vacuum in the sump increase blow by due to greater pressure differential? How often do we need to rebuild the scavenge pump?

[@YZFoFittie]

No, because that's how the piston rings work. That's like asking how many times should you wipe your butt...

[@AutoBodyEverything]

I don’t recall if this video clarified N/A engines vs forced induction engine!

[@dj4monie]

LS Crate motor is NA

[@gearrodclements7531]

Dry sumps actually help free up horsepower either way, when you run forced induction you increase blowby, but by running a dry sump you can still evacuate those gases and decrease windage.

[@snikwad003]

But how many horse pressures dose the vacuum suck up🤔

[@TheSteve1175]

Just subed,, 😁

[@stumilne5994]

Andre: "Just going back to your earlier point; In my drag experience, alcohol fueled on K Road, you would often find that even 5.5inches of head could lead to a bown rear ring seal, would that be fair to say?"

[@hpa101]

Gotta have a hobby! - Taz.

[@_i-kr6eg]

Alot of confusion, because it's expensive! not to mention plugging oil holes in the engine to suit . All the rest is not that hard to figure out just some people haven't got a clue

[@hpa101]

Compared to the cost of rebuilding some engines, it's cheap. Like all parts, not everyone needs or wants everything out there, but if the pros outweigh the cons for you then it's a no brainer, and likewise for the opposite - Taz.

[@soraaoixxthebluesky]

Never been so early

[@lukeericson4211]

Inches of mercury or inches of water?

[@rouanvanderende5922]

just show close ups of the actual dry sump please.

[@hpa101]

You will find these via some searching. We're more focused on the tech sorry - Taz.

[@asambi69]

I mean how reliable is it? Have they been tested by Manufacturers over several hundreds of thousands of miles?.

[@hpa101]

Many motorcycles run dry sump systems from factory, so in a nutshell, yes. That said you wouldn't fit a dry sump to your road car just because, this is really for competition vehicles - Taz.

[@dj4monie]

@@hpa101 Yeah and 98% of the people reading this despite the channel being what is don't race competitively at all, not even on a weekend warrior level. I like the idea of a dry stump for lots of reasons even on a daily driver. Tuners in general are worst cheapskates than broke muscle car guys. Like I said many don't race competitively but don't even have the fastest car on their block either so I wonder if they are really learning something with this videos. It is killing me that I can't compete at the moment....

[@ATLASGAMINGApallo]

Wait real talk Can I use vodka as oil?

[@hpa101]

If that is your dream, you sure can. We would advise that you don't however :) - Taz.

[@Iketano]

No dislike damnnn

[@hpa101]

There is now XD - Taz.

[@winstonhale4674]

No right or wrong...

[@coronapack]

When a nerd becomes a gearhead.

[@tomaspreece3126]

We need less chat and more images of what you are talking about... it's super boring seeing people talk for about 10 minutes and nothing else (you've been doing this a lot in your videos). Not even an image of the products. Take this as a feedback and not an attack.

[@dj4monie]

There is an image at the start of the video. Like most men you like Pictures more than words.
