Thread: Oil Cooler + VVL

Re: Diagram.
Filter on top, engine block on the bottom.
Edit: LOLWAT - Filter on bottom, engine block on top.

You need threaded and internally flared connections designed for the high pressure. AN fittings usually.

I can't see hose clamps holding 80-100PSI

so that diagram is engine > cooler > filter > engine.....

You have it backwards, the engine side from the cooler says in so it goes from the engine > filter > cooler > engine

There are little arrows pointing which way teh flow goes in that picture as well

Oh fuck. I think I was confused. In the diagram the filter goes on the bottom and the engine block is on the top. DOH!

LOL I didn't even notice that in your post. Ya block top filter bottom from what I can tell.

Read a lot of threads now about oil cooler installations and the one thing I don't get is why people say 90deg bends introduce a pressure drop.

Can anyone please elaborate on this? I don't see how a smooth flowing 90 deg an fitting in a pressurised system can cause a drop in pressure? Due to available space, I'm pretty sure I'd need 6 x 90 deg fittings to complete the install. 2 at the block, 2 at the remote filter and then 2 at the cooler in/outlets.

They usually use -8 or -10AN lines and fittings. Your not gonna see any noticable pressure drop by having 90 deg bends in the system. Not gonna happen. lol

^^ yeah that's what I thought too. I'm using -10 lines and fittings so flow should be fine. Thanks

Sharp 90deg bends do add a significant amount of pressure drop compared to the same length of straight pipe which is why people say that. I doubt it will cause too much trouble, maybe knock 1-2 PSI off the downstream pressure, there are online calculators you can use if you know fluid viscosity, pipe diameter flow rate etc etc if you feel like doing that. The reason it adds to the pressure drop is that it is harder for the fluid to change direction than keep going straight, the sharper the change in direction, the larger the drop.
