After scouring cylinder #4, I've decided halfway through the rebuild that it might be a good idea to install an accusump as well as the baffled pan. Probably going to go for a J's pan.

My question is, does anyone know the operating oil pressure in the F20c? The accusump should be at a lower pressure to ensure it can recharge and when pressure falls, it kicks in. Only thing is I would need to know what pressure the oil operates at so I can have a rough idea which psi the accusump must be at.

thanks

BTW going a little off topic here but I just wanted to say many thanks to Bassoctopus for his help in getting some spares (wishbones etc) sorted out, bought some spares off him and some he did'nt have he sourced from Honda for me. Just wanted to say top bloke.

 

Checked the manual
36 psi idle
85 psi @ 3k rpm
Based on 80C oil temp

let me know where you get the Accusump from I'm going that route but not bought yet.

 

Cheers Mikey,

looking to buy the accusump and extras from here:

http://www.accusump.com/acc_products/acc_units.html

If you click on 'which EPC valve do I chose', it recommends you know what your operating pressure is and choose below so that it can recharge whilst pressure remains normal.

 

yep done the research just need to find one at a decent price!
Merlin want

 

Using the link above it works out $495 for the accusump, valve kit and EPC valve set to 55-60 psi. Would be an extra $115 for the billet aluminum
mounting clamps. Trying to work out which would be best........

the 20-25 psi, 35-40 or the 55-60 psi EPC valve.

Any ideas?

 

Higher the pressure the shorter the duration of oil feed.
Lower the pressure closer to damage!
I'm considering 35-40 psi

 

Well looks like 35-40 psi it is then! I should be ordering it next week, shall I let you know how it works out?

 

Kartaphilos is running an accusump (ex PJL car). He might know about the setup.

 

I remember reading that, i thought it was a bit extreme for road use though, defo for track use, i suppose its all down to usage at the end of the day

 

PJL's car was built for track use effectively. And Kartaphilos has continued that, albiet with sprint regs in mind.
