anyone know if any of the 308 conversion kits/parts could be used on a 328 engine? Don't remember seeing anything about there ever being dry sump 328 motors, just the early 308s. | ||

Hi guys. I don't know about dry sumps helping to pull pistons down (remembering that the crankcase is basically open to the air cleaner), but I do know about windage.. i.e., the crankshaft expending energy to fling oil around in a wet sump. The windage thing isn't worth bothering with unless you're in ultra competition where every fraction of a percent may count, but maintaining oil pressure somehow seems like a pretty good idea. Having a dry sump, the main advange to me (in an every day sense) was that having a whole case of oil in that tank seemed reassuring. Andy | ||

Verell/Jeff Re-wet to dry sump conversion. Bill Pound used to sell kits to do the conversion. Requires removal of the AC compressor. About $3K I think. Philip | ||

re: DRY SUMP CONVERSION Search the archives. Some early Euro 308s had a dry sump, most likely these parts were the basis for the conversion. | ||

You forgot one little power adding item on the dry sump. Since the outward oil pumps in a dry sump system are in charge of getting all the oil out of the block and into the sump, they are big enough to pull pressure out of the sump. This, in turn, pulls on the pistons, and adds power! | ||

Has anyone converted their 308's (any flavor) from wet to dry sump? Details? Source for parts, etc... Inquiring minds would like to know  Jeff Davison | ||

Craig-Terry Great answer and link! Thank you..I'm not a 'sump dummy' any longer! | ||

easy: Wet sump engines have an oil pan on the bottom of the engine. All engine oil, after circulating around the engine, falls back to the pan where it is picked up by the oil pump. Dry sump engines store the oil in a seperate oil tank that is not an integral part of the engine. The oil is pumped from the tank, through the engine and back to the tank. The oil is not stored in the sump of the engine. Dry sump engines are better for racing applications for several reasons. Primarily because on a wet sump engine under hard cornering, braking or acceleration the oil sloshes around in the sump and this can interfere with proper oil pickup and thus constant oil pressure. In some cases on some engines this can lead to failure in extreme operating situations. A dry sump engine also weighs less and can give better weight distribution given that the oil tank can be positioned with weight distribution in mind. Also of critical importance is that a dry sump engine can sit much lower in the chassis than a wet sump as they are "shorter" without a deep sump to hold oil. This is why the engine in a Porsche 911 sits so low.... its dry sump. BTW: I mean on "real" 911's.... not this current batch of water cooled nonsense that Porsche peddles these days. | ||

Can someone please tell me the difference and what physical components in the car make up these two features? pros and cons also. |
