What compression are you guys running while retaining the stock style oil pump setup....maybe a better way to word this would be: At what compression do you need to change to a dry sump system?

Never heard of compression causing you to have to switch to dry sump. Most expensive motors are dry sump because they can afford it. They are better, & safer systems, and if you can afford a $40,000+ CAR & a $20,000+ engine, you can afford the $2000. I have only seen 1 stock location pump in anything over 1500 HP, but that's because he was kind of a newbie with that kind of engine with too much money. He's a little above 15-1 & a fogger. I'm no expert, I do have 3 cars with dry sumps, but not because of compression, because of safety. Good luck, maybe a engine builder will have heard of a reason & a general rule.

I am planning a 15:1 ETP canted valve motor.....where did you get your dry sump systems and what is involved in installing one on say a L92 style block

 

A motor my buddy runs has a 15-1 compression ratio with a stock style pump.

 

Dry sump is the best way to go but mostly used by people wiht big money engines.

You average motor or sotckish motor does not need one.

 

Don't forget really BIG engines, I imagine it is hard to feed oil to a 632 revving to 7500 with a stock style oil pump

 

My TT BBC will have a gravity feed oiling system......... no pump at all


Whats nice about the dry systems is it frees up power, crank is not hitting oil in the pan.....

But back on topic I don't think the compression has anything to do with it, its more based on RPM and how much money you have in the engine.

Granted there are guys in the 8's and I am sure the 7's with a wet system. To me 2 grand is a good investment.

 

If I had the $ I would run a dry sump for the safety for sure, and if the $ isn't an issue I would highly reccommend one. Personally I do not have one on my 10K motor, but if I had a 20K motor a dry sump is certainly one thing that would have pushed it to that price.


A vacum pump, and a dry sump are the 2 things I really want to add to my car, vacum pump will probably find it's way on first, but the dry sump will be the next thing.

 

Thanks for the help guys. You guys talked me into running a dry sump......I haven't researched what is involved in converting a wet sump system to a dry sump. Can anyone point me in the right direction?

 

Just buy a kit, there isn't a lot involved, basically the pick up is tubes mounted to the side of the oil pan, there is a belt driven pump and a tank that holds the oil, there are a few more pieces but you get the idea.

Here is a photo of a kit.

Converting is not a big deal. 1st, you need to have space next to the block. The most common is drivers side, but you can design it for either side. I'm using a aviaid on one engine & a SCP on another. I have vacuum pumps on both of these, but I will probably be going to a 5 stage with no vacuum pump soon. I saw a Pro-Stock guy doing it a while ago & he liked it. That was before they had these fancy elect pumps.
2nd, you tap the input from the pump to the filter for a plug. I prefer the block, but some tap the main.
3rd, they sell adapters to replace the oil filter, you use it to put oil into the filter output which feeds the engine.
4th, mount tank & then start measuring & cutting lines. Me personally would do the dry sump last because the -12 lines are much bigger than fuel lines & other wires.

There are several great pumps out there. Wolffe, auto verdi, moroso ect ect. The moroso web site has several pictures of routing, it will teach you the basics. I also use a dual filter system. Filters on the pan & filter on the pressure side. I use heaters & a temp sender for the data recorder. You can go stripped down with no extras like I did on my slow car or like I did on my fast car with dual filters, heaters ect.

There are several guys on here besides me, so keep asking & if I miss something, hopefully we can get you all set. I would decide on a pump company 1st & let them help you out. I already pretty much know what I want, so I have found a lot of stuff on ebay. Buy when I see something & save for the next project if the price is good.

Ok, so if I was to start from nothing. I would find a spot for the tank. Buy or build the biggest tank that will fit. Decide which side you will mount the pump. Find a good 5 stage pump. New if you can afford, lightly used if you have to. Start gathering up the parts & when ready, design & build your new oiling system. Good luck & ask away if you need anything.
