How do you plan to deal with the stock oil pump? Is it bypassed/removed or do you supply it oil with a low-pressure/high volume pump...or maybe just a gravity feed from the swirl pot? Where in the line does the oil cooler go?

Sorry if the questions are a bit much, it's just what I've been thinking about when I first thought about this. Actually, the idea came from my boss. He was giving me crap about his '79 porsche 930 turbo having a dry sump system and my car doesn't...

 

haven't entirely though about it, what style of a pump is it? vane or rotor? and what is it driven by?

as far as the oil cooler, we have yet to decide if an under hood or a in cabin mount is best, so as soon as we get that plotted we can figure out the way to route the cooler into the system.

and don't apologize for the questions, this is how we make a better kit!

 

Well, I'm pretty sure it's a rotor and driven by the...uh...motor. Might be gear-driven, but not sure off of what. Just think of the damage I could do if I attempted this!

 

How much would something like this be?

 

depends on the size of the pump needed, I'm not sure what oil pressure needs to be made in the motor, prolly under $2k tho.

and yes i agree with you that you couldn't have someone tryin to rip out and oil pump. Why would you have to block it off anyway? If the dry sump pump was making a higher psi, the rotor would be inconsequential, even if it couldn't slop enough oil into it, it wouldn't be a big deal. The only thing I could see with that being an issue is if the rotor actually blew up and fragmented, I haven't heard any stories of that happening tho.

 

I was thinking more along the lines of overpressurizing the oil system, blowing out seals, etc...

 

the dry sump over powering it?

or the stock system?
cause the stock pump won't increase pressure after the dry sump, it'll just flow.

 

Stock system. I was under the impression the gear/rotor pumps will pressurize whatever is sent to them at a fixed ratio. Say the stock pump pressurizes 10:1, and the input side of the pump is around 1psi, so the output is 10 psi. Well, the dry sump pushes in 2 psi and, well, the math is easy enough.

I apologize if it seems like I'm insulting your intelligence, that's definitely not the case. I certainly can't design or build a dry sump system like you guys. I've just got some experience with F-15 hydralic systems and how their pumps work, so I thought the stock pump would do the same (sort of).

 

pumps don't create pressure, they just create flow. Pressure is the resistance to flow, and if the oil is already hitting resistance before it hits the pump ( which it inevitabley will coming from the dry sump pump ) then the stock pump is just sloshin it forward. I'm not sure if the pre-exsisting pressure would interefere with the stock pump trying to flow it forward, these are all issues we are gonna have to hammer out when we get the oiling system dissected and figure out whats happening. We could just make a plug for the oil pickup and have it reverse flowed from the head down so the pump could be totally bypassed. But once again I'm not sure.

 

Ah, good points.

 

LOL i knew that $31K education from wyotech would come in handy! Forums!

 

So for engines (in this case) oil demand is flow based(?). Is any oil pressure required to get oil in the journals/bearings?

In aircraft the hydraulic systems are definitely pressure based and the pumps are designed to compress the fluid to roughly 3000psi. They have the ability to vary the compression ratio in relation to the input pressure, pretty cool stuff.

 

this is a really good idea, there are no dry pumps for the evo yet

 

Im running a deadbolt 16g perrin fmic, pe650s, utec, all supporting mods. Big valley is running a 35r and i believe they won the shootout at e-town this year. Not trying to start anything just stating a fact.

 

Im down to make it for you guy's, just need to get the ball rolling. Ill try and get an evo oil pan and then have it sent out to have the new shallower one made.
