Is it possible to switch our cars to a dry sump setup? If so any ideas on how much one would expect to pay for such a switch. For all those all motor freaks im sure this would net a good 15+ hp, or even for anyone this would be a great upgrade given an okay cost.

umm? anyone anyone :) Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller... Bueller...

this the only dry sump on a sr20 that i know of:300 HP NA SR20DE (http://www.sr20de.net/multimedia/pictures/300hp_na_sr20/)

Of course it's possible.

How much money have you got to burn? :)

I can't remember, but it's in the low thousands IIRC.

Why do you think this would net any hp?

I've read that it reduces the parasitic drag of the crank cutting through the oil. Also, it eliminates the internal oil pump of the engine and relies on a more complex (and expensive) oiling system consisting of at least two external pumps. It may produce 15 more HP, but you have to consider that the SR20 engine has a two piece oil pan. Knowing how low the crank girdle resides in the block, I really don't see how a dry sump would benefit a SR20. If you remove the primary (middle ) oil pan, you'll see that there wouldn't be enough room to create a dry sump worth doing.

The crank doesn't cut through oil except for some atomized oil in the "air" in the engine, but a dry sump won't eliminate that.

Well I certainly can't say that it won't, I'm highly skeptical. Yes, you eliminate the oil pump run off the crank, but you then have a pump run off an accessory belt off the crank, so what have you gained? Perhaps the accessory pump is more efficient, but 15 hp more efficient?

It would let you lower the engine about 3" in a race car and lower the CG of the engine even further if you can tip the engine back a it.
