btw there car makes about 470ishkw so yeah

just a conversion getting thrown in. 470Kw = ~630 HP

Not necessarlly. It all depends on the design and intended use. However, most are over designed.

There is a vid of big block wet sump on dyno that they remove 1 qt and it gained noticeable amount of hp. this was large wet sump i believe 6qt ,so they ran 5 qt .

Less volume of oil in the crankcase = less windage = less hp to spin the crank = more overall hp
Using a extra quart oil pan with one less quart of oil helps to achieve this without loss of original intended capacity.

Don't use a crankshaft, they are heavy and inefficient.
A drysump means you can run the oil pump using an electric pump instead of engine power and make more HP.

i think all of you guys are missing the point. This is a eco website that is greared to helping the enviroment and reducing our dependancey on oil. Well if you have a oil bypass system you only need to change the oil once in the cars life and just add oil if the motor burns it up. leaks it etc. Over all if you own a car for say 200,000 miles and its a 5 quart system and you change the oil eveyr say 5,000 miles that equals over 200 quarts of oil compared to a bypass system that only needs 5 quarts plus or minus say another 10 at most for oil lost, burned, etc.

And if you bring your used oil in for recycling...

A rotary doesn't have a crankshaft, and I think its quite funny!
And two strokes don't have oil pumps or oil pans.

Not sure most performance dry sumps have like 3 stage oil pumps compared to single stage in a wet sump . you do get advantages as you pointed out with windage as it is dry now and of course main one of no starvation in high G forces .Most engines have no shortage on hp that use dry sumps (not used on many passenger cars except a few sports cars like 930 ).
I try an find the vid it was showing the differences of different oils and then running the engine low by 1 qt which on this extended pan is fine .

yes I did miss the point, because you didn't make it.
My apologies if this was your intention, looked like a spammer posting to me.
As usual Frank is right, you can recycle used oil, these days used oil is actually very valuable.

Glancing at the amsoil site, looks like the system would be $200+, + effort to install it, might void warranty, and then $38 dollar filters. 200 quarts oil, and 40 filters when spread out over 6-7 years/200,000 miles is more ECO friendly to me.
Those systems can be worth while when your talking gallons of oil in a engine, but not 4-5 quarts, when you get into gallons, sending out samples for testing can even be worth while.
I'm here to learn how to save $$ not the world. Burning E85 in wife car to save $$ and as a plus part of the money stays local, when E85 cost more per mile back to E10.
