Pinto Dry Sump System - Pipe Diameter

[waynemk2]

Hi Guys.

Just looking for advice.

I fitted -12 dry sump pipes and unions to a pinto.
Boot mounted tank. -12 feed, to pump, -12 from pump to filter head -12 return via cooler.

Now been advised that they should be 3/4, the way it is at the moment could see pressure drop off, and not to run the engine until its changed.

What are peoples opinions out there.

-12 is 3/4

I use;

AN16 from tank to pump
AN10 pressure out to block
AN12 scavange to filter
AN12 filter to cooler
AN12 cooler to tank

Never had a problem but that doesnt mean it is the best.

Boot mounted tank
Will work ok with -12 to pump
If it’s a good pump but -16 would be better

Then -10 from pump to filter head
-10 from filter head to engine

Oil pressure switch in block not filter head

Then scavenge

3/4 pipe or -12 x2

Then either -12 or -16 to cooler
Then to tank

Also you a good oil cooler and good filter
Head as these also make a difference

Smooth bore pipes always

-12 the lot never had a problem. I only run one return line in -12 and it’s fine
