Low oil pressure alarm point

[neil a]

Going to be setting alarm points on my dash2 , what would be the recommended alarm point for a track use f4r ?

It all depends on how healthy the engine is really mate. I’ve seen them as low as 11psi on hot idle!

Mine idles worryingly low even with the oil pump mod.

When you say the oil pump mod, do you mean the shim on the oil pressure relief valve?

Yes, although I did it this way. Is that what you mean?

Yeah that’s it mate in either way shape or form. We do more than that with them and we also fit restrictors in the block to head oil drilling on a full build.

Yes I noticed you do that. When the time comes for a rebuild I may pop it up to you for that.

No worries mate. We do lots of different stuff to other people, but it works and it’s proven itself over and over again. I actually had to remove the shims on my oil pump as the pressure was too high! Lol! 118psi cold! ?
Ashley’s engine is another one that’s made cracking oil pressure.
