Oil Pressure Drop On Boost.

[EAT26]

Mmmm 1300 bucks haha

U doin sump baffles, oil return/breather from the head Etc?

Dan is pretty much making all the decisions lol. I just told him what I want out of the car etc and he will work with what I want

I am not sure on what parts are going in just yet I know the basic stuff just waiting on the list to be sent through.

[GTR_JOEY]

Righto well keep us updated with parts and costs mate

Once I get the list Ill post it in my build thread. and once I get the problem Ill post in here

....and once I get the problem Ill post in here

yes please, in particular oil pump and big end bearing condition. My guess is still on clearance problems causing pressure loss under load.

Put it on the dyno and see if it still drops pressure, will narrow down if its the Gs or some other issue.

Did you ever try this? It will very quickly sort out if it is an assembly problem, or a sump design issue.

I personally filled the sump with 6l as its the standard sump it still did it, so I am guessing it is oil pump issue but yeah wait and see I guess.

I suggested putting it on the dyno lol, not overfilling it.

Yes however you also said sump design which is standard hahaa. No we did not put it on the Dyno. I am just playing the waiting game hahaa lol.

Yep the standard sump might not be sufficient for the Gs you are pulling is what I was getting at, hence put it on the dyno and it will very quickly tell you if it is an issue with the sump, or an issue with the build.

Engine is half stripped down after this photo, still no reason why there is a oil pressure loss but Dan did find some metal shavings in the sump.

[Rolls]

So you never tried it on a dyno to determine if it was the oil pump or the Gs and stock sump?

I think he was hell bent on pulling out the engine and stripping it...

Stop being logical Rolls

Money burns holes in pockets.....did anyone say power trip?

No we didn't, however some what glad we didn't. Found half a washer(looked like a washer) in the sump just floating about. If I would of upped it more and more I could have done more damage.

The crank so far looks good so there is no need to replace that yet.

I have gone by what Dan has said and he are still trying to diagnose the issue.

[Rolls]

I hope you find out what it was, would be a fair pain in the ass to put it all back together and still have the issue.

[EAT26]

So my first piston is a bit gone.... lol. hahaha

[Rolls]

Interesting...

[GTR_JOEY]

Pretty much what my number 6 looked like when it let go....

it had standard pistons running 285rwkw.

what generally causes the piston to break away like that... is it just cause they're weak? or is there other contributing factors?
