Oil pressure F4R 832

[Nikidani]

Hi guys! Have you ever heard of calibrated holes to be inserted on the engine head oil supply pipe to increase the pressure on the lower part of the engine? .... If so, does anyone know the hole diameter for an F4R 832 with hydraulic tappets? Thank you!

You won’t need to do it on the 832 mate. It’s only the 73x series engine that needs.

No problem of pressure in F4R 832? Sure?

 

[bloke]

Just the normal bottom end problems on no.2

It’s more harmonics that cause the problems like @bloke says.

Thank you guys!... You're the N. 1

[QUOTE = "NorthloopCup, post: 11707638, membro: 61663"] Sono più armoniche a causare problemi come [USER = 98854] @bloke [/ USER]. [/ QUOTE]

.... Allora cosa fare per aumentare l'affidabilità di F4R 832? .... Per eliminare queste armoniche?

What’s that in English mate? Lol!

Sorry NorthloopCup!

.... So what to do to increase the reliability of F4R 832? .... To cancel these harmonics?

Dynamically balance all the rotating assembly mate.

I trainer francesi dicono di aver risolto il problema della biella che sfonda il blocco posizionando le scanalature delle boccole principali sopra e sotto, viti ARP sulle bielle e olio 15w50 .... Che ne pensi?

Sorry!
The French trainers say they have solved the problem of the connecting rod that breaks through the block by placing the main bushings grooves above and below, ARP screws on the connecting rods and oil 15w50 .... What do you think?

We’ve been running full grooved bearings for ages mate. Lol!! Took them long enough to work that one out!! ?
15/50 isn’t so necessary though. Mine ran fine on 5/40.

Thank you NorthloopCup!

Always very kind and prepared!
