Just was wondering if anyone has ever tried a dry sump system b4 and would it work on a CA?

In progress! I have been hampered due to money and time because I am getting married in a month. I will be getting my motor in a week and I only have to get my oil pan finished up with the correct bungs for the pump hookups and various drains in the pan.

I have to ask, why are you guys so bent on having a dry sump, when you haven't even put the wet sump to the test yet. For most of your needs as well as my own which is pretty needy, that wet sump set-up in that engine is more than sufficient. Unless you guys just wanna "DIFFERENT", something is going to go wrong and you may end up selling your CAs as well. Build some respectable power first with the stock set-up and see how much need you have for a dry sump.

Thank goodness someone posted this post...

If you research the operation of a dry sump system, it will be an expensive excerise if you want to be different....

There are alternatives to dry sumps, however if you have no other choice, then so be it.. research wisely

My entire dry sump system will be costing me approximately 850 dollars and a little spare change. I bought a used pump, had it rebuilt, and the whole shebang wasn't even 500 total with shipping to have it rebuilt. It is a nice 3 stage barnes with a built in oil log and high pressure reg. I got about 20 different 12AN lines with many random fittings, all reusable style, with lengths of hose from 6 to 40 inches, 10 of which are anti collapse. I also got a FREE nearly new 4 gallon tank from the hose seller. All of those with shipping was under 150 bucks. I am making my own oil pump bracket, pan, and filter setup from scratch, and I have 250 in EVERYthing for that, including a small used mig/flux core welder that I am acing the use of quickly.

The reason I am going dry sump are many, and have been posted before. Mainly though: with this kit installed and pulling a slightly negative vacuum at all times on the block, I should be netting at least 20 more wheel horsepower with no other mods. Not to mention, my motor will be 3 inches lower and 4 inches further back than with out this setup, and I won't be forced to stick part of the valve covers under a cutup firewall with a heavily modded subframe that would drag most objects sticking up off the road. and the motor will be much more reliable.

Dude, the post was generalised and not directed at anyone specific.. You don't have to keep justifying to me why it is your doing what your doing.. Not being negative just stating that its all good mate..

You have explained in your other topic already... I understand your reasoning as you are forced to use one and to be brutally honest, I am not particularly interested in your detailed dry sump configuration..

I am mererly agreeing with boost_boy that it seems that a lot of people (not yourself) are jumping on the dry sump bandwagon lately (not just in this forum, but others) without fully understanding the concept or reason behind employing the technology....

I believe the majority of people (again not yourself) read forums and think "yeah man, I am going to do that cause it's totally baller or sic" rather than identifying the actual requirement, 9 out of 10 times this is where projects break the budget and dissapointment sets in...

I helped a guy get a dry sump system. He stole my wheels so I loosened his drain plug. He blew his engine so I think dry sump might be a bad thing.

Hey buddy, why do you think I keep pointing my words at you? Quit trying take away from the real and true facts I post from my real world personal experience. I am not attempting to justify my decisions in the face of anyone; I am attempting to sell some fresh people on a truly wonderful technology; they asked about dry sump on ca18's, not why not to do it. To each one's own I was told once, and that was the last opinion I ever really listened to. Take what I write as what it is.

"You have explained in your other topic already... I understand your reasoning as you are forced to use one and to be brutally honest, I am not particularly interested in your detailed dry sump configuration.."

I wasn't answering your question. XTCshri2222 asked the question.

"I am mererly agreeing with boost_boy that it seems that a lot of people (not yourself) are jumping on the dry sump bandwagon lately (not just in this forum, but others) without fully understanding the concept or reason behind employing the technology.... "

That's nice, I was merely disagreeing. Maybe if people that don't have to because of weird projects are still going over and experimenting with this technology, it has real world potential to make a difference that IS worth the time and money. Maybe it is also possible they wish to learn more about it being applied to different motors that it isn't currently popular to do so to. The only way I have found to see how well something will work is to put it through it's paces.

"I believe the majority of people (again not yourself) read forums and think "yeah man, I am going to do that cause it's totally baller or sic" rather than identifying the actual requirement, 9 out of 10 times this is where projects break the budget and dissapointment sets in..."

Tell him that, not me, especially if you are going to acknowledge all of these statements are not pointed at me; thanks. (-And 9 projects out of ten I have ever done went horrribly over budget but i was happy as a pig in crap everytime because I achieved my goal no matter what, and got what I wanted out of my attempt.)

I was just curious if anyone did it, i was looking to do something like that if it was not to much of a pain. Just to be different, but seems like a pain. So i'll stick to what I have now.

My comments were not directed towards yourself, it was a generalisastion, actually I never even thought about your build when posting... But for some reason you really are quite defensive about it...

To be honest I really don't care about your particular setup or experience or knowledge, it works for you so good on you

Also you have absolutely no idea of my experience (and I cannot fathom yours), however I choose not to discuss the design and technology that is being implemented into my current CA18 build...

I never said dry sumps were not wonderful technology, in itself it's absolutely fantastic if you are going to use it in the right environment..

However it will not work for everyone, so for XTCshri2222, the topic starter and the person I assumed would engage with some converstaion, I will state again from my previous post....

Yes there are some people that have built these system for the CA18 motor..

Zmannz seems to be the goto person on these forums for this particular technology, maybe ask them for some advice, seems to be happy to provide an opinion

I have researched some examples in australia, but they are few and far between...
