Oil Control In Rb's For Circuit Drag Or Drift

[KiwiRS4T]

this thread has turned into how to make your rb survive at the track without a dry sump

not dry sump talk

Quite right. I and a number of others have found that with the right combination of restrictors, sump breathers and a properly designed catch can system the problems can be overcome. My catch can vents to the turbo intake so is a completely sealed system. If there had been oil laden fumes going into the turbo I would have added another air/oil separator into that line but there was no evidence of that being necessary.

Sending the blow buy into the turbos through the engine and out the bum is not a sealed system

ASR do have extended sumps MrFIjiGold had a word with them and initially they wanted to use my car to design it however. Unfortunate happened and it's no more. I recommend you give them a call the big problem with out GTTs is that they have to design around the sway bar

He no longer has GTT

And the big problem with my GTT is i still have no oil pressure under braking hard with ASR sump...

Perhaps better to describe it as "as sealed as an OEM system".

Have you guys ever had that setup kill a turbo when to much oil gets blown into tge turbo. ??

[fatz]

I think my setup is for people who don't want to pull the head and slip in a restrictor

I once had that issue in the early days, it didnt kill the turbos.

But it did end up smoking under boost like it had a blown turbo.

Ended up being oil had pooled in the intercooler piping just before the intercooler, cleaned it all out, was back to normal.

If you get oil mist going in it will probably be fine. If the oil-air separation stages fail to do a good job and you get large drops hitting the comp wheel, it could possibly do some damage.

[MJTru]

I had the same thing happened to me years back. SAME thing really left me worried that if enough oil hit that wheel at high speeds it could destroy the turbo. Thats why I asked.

fatz you lazy bastard put some restrictors in, that's a big part of the problem right there. Oil does no good for your engine when it's all floating around at the top.

Lol. I would have though he would have done that with that setup looking so good. I would agree. Spend some time pickung the right size according to your pump options.

[fatz]

Lol you guys talking about pulling heads off and doing all this fancy shit

Meanwhile I am out thrashing the car at the track thus my over the yop catch can setup with scavenge

My setup also factors in when you engine starts to wear out it gives you options to prolong the engines thrashing life( now that the engine is blowing buy abit more I can activate the scavenge )

If I rebuilt the engine I would stick one in but f**ked if I am pulling apart a runner..... Once you let the Nissan out they are never the same

[MJTru]

Your right they not the same. They become monsters.

[MJTru]

Wit a good tune of course. Lol:blink:

[fatz]

yea you don't see many 400 plus rwkw gtrs going nonstop all day

I only have 310 and I keep killing thinga

[iruvyouskyrine]

Fatz has the idea. Drive it and deal with it rather than pulling the engine out and sitting at a keyboard arguing over the Internet with people that your engine will have zero oil issues and you will do it this way and they should to, and then you realise you haven't driven your car for over a year and won't for another few months when the person with the issue is out wringing their cars neck every few weeks.

[GTSBoy]

Perhaps. I suspect that anyone who is serious enough to care about this stuff (enough to do something about it, that is) and is permitted to spend/waste money on their car by the domestic authority (wife) shouldn't be so short of cash that they wouldn't just buy and build another engine out of the car while driving the original.

I do a lot of car things the cheap way (or not do anything at all!) because between myself and my wife we know that it is just a waste of money, even taking into consideration the philosophy that anything you enjoyed wasting was not actually wasted. But if I decided that I just couldn't put up with the 9 or 10 things about my car that are currently bothering me, I'd just go spend the $10 or $15k that would be needed to right it all (properly). I think the engine building stuff really ought to be done the same way.

[fatz]

If you built a motor 20 track days later you will need the catch can setup anyway because when you thrash a car they wear out

400 kW cars wear out quicker as well

[KiwiRS4T]

Have you guys ever had that setup kill a turbo when to much oil gets blown into tge turbo. ??

No. As I said if I thought there was a likelihood of that happening (e.g. traces of oil in the line to the turbo inlet) I would have put an air/oil separator in the line. My catch can seems to do what its intended to do.

[fatz]

Thrashed heaps of 25s at tracks and they were never a issue unless they were high I. The leak down teat
