Engine blows out
At 80mph turns in the twins boxer engine would all the oil go to one side causing the other side of the engine to have no oil and blow out?
|
If you're a baller convert to dry sump and all will be well. I know this will really come in handy when daily driving.. At 80mph. I worry about this with my sprintex. Dat shit eats oil doe.

I have yet to hear of an 86 that is cornering on such extreme banks at such speed that oil starvation is occuring. No worry.

However if you start tuning with forced induction (300+ I think) and do hard turns on a track you could get oil starvation in the crank, specifically around the rod bearings. There's a big thread in either the forced induction or engine forums (can't remember). There's a workaround, but it's expensive and somewhat complicated. The issue here is oil pressure more than anything else. |
Speed and power are irrelevant to this question. What matters is sustained lateral acceleration. Sure, a high enough, sustained lateral g-force will cause oil starvation. But that can happen with 100hp or 500hp, at 60mph or 130mph.
What is the maximum sustained g-force that will cause oil starvation on the twins? I have no idea. It might even be different depending on whether you are making a left or a right turn.. |

How does that link contradict what I said?

However, in the real world it's not just how many Gs, but the oil pressure (lots of contributing factors) mixed with the Gs (and angle), mixed with the design of the engine that will decide whether you get oil starvation and where it is. OP asked about this particular car, and oil starvation in the heads due to the boxer layout. In this case it just isn't going to happen. If you've got a heavily modified car in extreme circumstances you can get oil starvation... in the crank. Real world is just never as simple as a single force. So as mentioned earlier by evan, a stock FRS/BRZ isn't going to get oil starvation due to hard banking. |
Go home SquadRogue, you're drunk.

Squady put it this way; if while driving an FRS, you are in a turn that fast, long enough to drain your oil to one side, you already know the answer to your question and what to do about it!

my biggest problem was not oil & g forces, it was fuel and g forces
DAMN LEFT TURNS I setup the car to handle like a beast, it did just that sold the car because the fuel system is crap and no pump any vendor sells you is gonna fix that, it wasnt worth it for me to throw a motor at the car and a proper return type fuel setup(new custom fuel cell or new fabbed up tanks in oe spot etc), which was my next and only possible step; tracking the FA20 in stock form has its limits, the weakest link is the tranny, then fuel then motor. fix all three and I would have kept both our brz a vette motor swap was on the table but for that money plus our trade we are making a cayman s into a track car that will easily EAT any frs or brz no matter how buit up...(adding quaife or guard LSD, JRZ coilovers,---> evoms rs350 kit<--- just wow etc etc) all for same money as trackifying a 86, proper and no left turn fuel starvation, I dont miss that one bit! |

I apparently need a more sensitive Torllometer as mine only goes to 10,000 disbelievawatts and Squady may be coming in higher. |

It has zero to do with HP, EXCEPT - that High HP engines require more consistent oiling due to greater forces within the engine (which has little to do with lateral G-force) So High HP engines are more susceptible to oil starvation. Back on topic: IF you have oil starvation issues (you probably wouldnt know it unless you have an oil pressure sensor and log the data), then the solution for racers is an accusump. If air is ingested by the sump pickup, the accusump will "burp" extra oil to keep the pressure up until the bubble clears the system. Of course, the accusump can only do this for a few seconds, so a long sustained curve could still cause starvation. Of course, the BEST solution is a drysump system with a resivoir & dual oil pumps. |

Bitter breakup huh? I'll bet it was repossessed and you just dont want to admit it.... |

Pics or it didn't happen, anyways. |
At least kiichiro is claiming some kind of knowledge, the rest of you are armchair quarterbacking about your daily drivers.
And what he says makes sense, in this car you will likely fuel starve before you run into oil issues on stock powertrain. |
Anyone thought at that speed the car can oversteer?
|
The OP is why I have no hope for this country.
|
People like CSG, Robispec, and Element have cornered faster than you probably ever will without reporting oil starvation from turning. Element has dealt with oil pressure issues, but that's due to engine power, not turning.

Or are you arguing that an Accusump will NOT help with oil starvation..... Quote:

I blew my motor and I think oil starvation was a large reason why.
I have a oil pan baffle on my new motor. |

The OP was asking about a stock car at stock abilities not some ultramooded hyper race machine. So the answers given were reasonable not "arm chair quarterbacking". He received his answer within 3 posts and the rest are redundant and simply argumentative anyway. To go into the whole fuel starvation thing is a whole different topic and not only doesn't answer the question it was posted with questionable motives in the first place. There is nothing wrong with the tech crowd wanting to have there debates but they frequently reach levels that become so theoretical that they become meaningless for the average guy out there anyway. Squadrouge asked if it is a problem the short answer for him was no unless he starts heavy modding and extensive tracking. |

Notice I didn't say anything about the OP's question, and yes I went off topic to point out how weird it is Kiichiro continues to come here despite his obvious distaste for the platform. He calls it a "toy", when people may not be looking to competitively race their FRS but have an outstanding little racecar to daily drive, weekend warrior, etc... to which many will attest that the FRS goes above and beyond to accomodate. Would love to see VW/Porsche try and come out with a comparable RWD platform for the same pricepoint, and then we can split hairs. Otherwise there's a bit of issues the guy must be dealing with to continue and try to assert how right he is by jumping ship |

I agree with you on his attitude and motivations but I wouldn't snub information from the biggest **** on the planet if it's relevant to my needs. Quote:
See you at the track. :burnrubber: |

Putting a oil baffle plate into our oil pans is not a bad idea for insurance purposes if you are tracking your car or running a tapped oil pan. |
I'm SKAsphalts 1000th thanks. My work here is done. Carry on.

Canadian Tire Motorsport park is ~2 hours 45 minutes from you. You've got three tracks that are within distance for a weekend trip, book a hotel, take off work early on Friday. I dismiss your excuses. :burnrubber: [ame="https://www.youtube.com/watch?v=sTaLs6eT7V0&x-yt-ts=1421828030&x-yt-cl=84411374"]Scion FR-S at CTMP DDT - YouTube[/ame] |
