they were talking about them at the track day, b/c of the guys that got rod knock, said they were going to get ve oil pump so they didnt get oil starvation

so the normal FWD DE's are wide blocks? so we can get the whole package that they offer for the SR correct? thanks

Having a larger pump has nothing to do with oil starvation. Having enough oil in the pan is a prerequisite.

That is why you need my new invention. It is called the "oil adder" TM (C) Pat Pending.

It is a revolutionary new device. That makes sure there is oil in your pan.



Remember TM (C) and pat pending so don't try and steal my idea.

You say you can offer a pan... then in the end just offer what is already available and doesn't address the issue that originally started your offer. Crank scrapers help knock oil down, but it doesn't fix the inherit oil issue with the sr20 that prompted this.

It is very possible to make a better pan setup, but the problem isn't designing it IMO. It is that nobody would pay what it costs to make since it is such a small sub group that would be interested especially with the variations in upper pan to block mounting.

I am not knocking on you for not making and selling the pan... but just get your story straight is all. If you were looking at just growing the pan down to increase capacity you SEVERELY misunderstood the issues people were talking about and the problems with sr20 oiling.


We spoke with Crank-scrapers as mentioned by many members on here and Kevin advised that the options he has are the most effective and efficient. He said making a new pan would not be cost effective due to the many variations like you stated. Plus, we would have to make a deeper pan which in many cases would bottom out over speed bumps, etc.
We have discussed elongating the pickup tube to deepen the pump, but we would have to modify the pan to drop the pump in more.

I apologize for the confusion, hope this helps. If it was me, Id run a Teflon scraper, budge removal, VE pump, straight weight oil.

Anyone looked into these ... http://www.drysump.com/pan30.htm
BTW that pan is $589 and that just the pan, no lines, pump, ...

I guess Im trying to find the middle ground as everyone know a dry setup would and could cost $$$$

This causes foaming!

how would a dry system affect having the factory oil pump?
since a dry system uses an external pump...right?

I'm not absolutely certain on this, but I'm pretty sure there are other factors other than the VE oil pump that keeps the VEs from ruining rod bearings as easily as the DE(T) guys (if even that assumption is true). The higher oil pressure is great, and can probably compensate a little if you have a dented pan. The oil pickup is also a little different which might also help if you have a dented pan. This is probably only half of the story.

I can only assume the oil passages throughout the entire block are better sized/routed/designed to provide oil to the main failure points. Instead of running low on pressure to rod bearing 3, a combination of high pressure oil pump and better designed passages must keep oil pressure where we need it most a bit better.

The problem with lateral loads and oil starvation are obviously not solved by an oil pump. It might be helped slightly by the oil pickup, but not from the looks of it.

This is where the redesigned oil pan idea comes in. One-way trap doors, better baffles and oil control is the key. Keeping oil down in the lower oil pan is the goal. It seems like this route is not worth it though.
The other way to keep oil in the lower pan is with the use of crank scrapers, upper baffles (both already produced by Kevin) and slightly overfilling the engine (too much and you run into foaming).

With this discount on the crank scraper and upper baffles I'd be all over them if I weren't under such a tight deadline to get my car finished.

That is what I was getting at. People wanted to have new pans to fix the problem.... making a pan that would fix the problem would be just as much or more than drysump...

It CAN be done... But it shouldn't be done for the cost/benefit ratio.

Also if anybody wants I will gladly design a pan that fixes the problem... Provide you prints you can take anywhere to produce and even source parts if you want. Half down to start and I bet nobody will like my rate.

Has anyone seen how much the dry sump system is?
Is there a kit, or is it all pieced together?
