Dry sump pump in stock pump location?

[Stinky]

Have any of you guys looked into putting a dry sump pump in the stock pumps location? Obviously there would need to be some major block modifications. I'm just thinking it would be nice to use the stock chain and gear to drive the pump and also keep it from taking up extra space. Thoughts? Am I crazy?

It would be very difficult as you're probably going to run a 3 stage pump which will be at least 3 times as long as the stock one. You'd also then have to externally pipe all the feeds etc.It might be possible to bore through the block in line with the shaft from the pump then run that out of the back and drive the pump but you'll be intefering with the mount locations etc then.Have a look on some of the pics of my engine on here, you'll see the rough size of a 3 stage pump.

There is a guy that did something with his stock pump. I think he's a Kiwi or Aussie and can't find the pics. I think he routed the oil outside the pan from his pan to his pickup via bolt thru pickup tube. Then after that he made a flange on the stock filter location and ran AN's from there.

I'm pretty uneducated in dry sumps, why is there a need for a 3 stage pump? The stock pump flows 80 psi at anything above idle. Please school the newb.

Two of the stages siphon out the oil from the pan (F&R) and send it to the oil reservoir. The third stage is fed from the bottom of the reservoir and feeds oil to the motor. There is really only one stage in the Dry Sump that is feeding oil to the motor.

Same Here T45, curious, why the 'great' oiling abilities of this engine are not good enough. Seems like a good setup, plenty of pressure, and if redo the oilfilter assy, then you could run hoses out of it to oil filters, cooler, and such. looking for more info too.

The stock pump is great for a stock setup. However, under extreme Accel and Cornering the wet sump can go dry as oil forced away from the pickup. A dry sup never experiences this, since the stage of the pump that is oiling the motor is fed from the bottom of a tapered oil reservoir.

A dry sump is rarely, if ever, needed on a street car. But the benefits above, plus the ability to place the motor lower and the reduction of windage losses make the dry sump very appealing for a track car.

[John Dixon]

Exactly what he said ^^^Also, you can pick up power from running the crankcase down to a vacuum so there are less pumping losses from moving air around underneath the pistons. Oil leaks tend to dry up to which is a side-benefit.It's a lot of extra complication and cost though. Don't underestimate the cost of the hoses too, can cost as much as the pump and tank etc easily!!

Thank God I am building a street car. $$$Dry for track, yes.Didn't realize so many people on here are building for such extreme use, I guess drifting is a big reason. I figure even if I get to go boost, stock pump should work for me.

[John Dixon]

Mine's a street / track day car but will see some pretty serious use. Dry sump may not have been necessary but I kinda enjoy the engineering side of it all too and would rather not have to do it again. Also with the $$$ I put into the engine I'd rather not risk it (98mm overbore, custom pistons / rods / headgaskets, solid lifters 70/30 30/70 @ 50' cams, ITBs, tubular headers)

[Chrispy300]

I'm also going the dry sump mainly because I can

I like a challenge and my car is being built for track and targa type use

[T45]

Thanks for the explanation. I wondered why the pan I saw had 2 lines coming from the bottom of the pan, I couldn't figure out where they would go.

I'm glad I turned mine into a rear sump now, daddy feels much better!
