Okay, Me and a buddy were out playing in the talon and theres this new residential area that is newly layed out. No houses, just nice pavement and curvy roads. I come up to this hard right 90 deg, dropped to second(5000RPM) and took this corner hard. (I love the new coilovers) The point to this story is that the car bogged down under acceleration through the corner. WTF? So I turned around and did it again. It did the same thing.

I have never taken it that hard around a corner and had this happen before. What is happening. Is this what a crankscraper fixes?

Bump!

I've been noticing this lately too. I think it has to do with fuel pressure and fuel sloshing around in your fuel rail. Check your pressure. I need to, just haven't yet.

It's wierd. I've never had it happen till I took that hard right!!!
Do I have crankwalk!!!!!!!1 lol

oh god, justin99rs and i were talking about this the other night, lol. its the fuel sloshing around, or at least thats what ive heard from the neon guys (i drive a neon, lol). i encounter this EVERY day. stupid neon! :afro

actually its probably your turvo not getting sufficient voltage...lol :afro

Yep, it's fuel loss. Lots of the road race and auto-x cars have fuel cells with baffles to prevent this.

"its the fuel sloshing around"

Yep. Buy the crankscraper and your problems are sloved. I've auto X'd with the "crankscraper" or baffle a few times with no bogging problems.

UHm, that makes no sense dude. The crank scraper keeps your oil down in the pan and stops your crank from making a big whirling mess out of your oil which slows down the crankshaft. It has NOTHING to do with fuel delivery.

I think it's fuel. O well. Nothing by the sounds of it will fix it.

Yeah dude, get your fuel pressure checked. I have a bad FPR and just haven't replaced it yet. So either that or your pump (not likely) have gone bad and you're not getting the right pressure in your fuel rail.

OOPS sorry i meant to say OIL.

Just completely fill up your tank with gas. Even if you went through the turn at 3 gees a full tank would eliminate fuel sloshing as being the culprit. If the bog still occurs then it is something else.

If your fuel injection pump is not capable of pressurizing the fuel rail so as to resist the modest gee forces in this sort of turn then you would probably have real drivability problems even when not turning.

My guess would be that your crank is suddenly trying to whip up 4-5 quarts of oil as it stands up against one end of the pan. Uses up a lot of energy. Be careful, though. Many, many people have blown their engines this way (usually you will spin a bearing and if you keep driving then you throw that rod or ruin the main journal).

it's the oil bud. get a crankscraper and you'll be done with that. your fuel rail is under pressure so it wouldn't matter if your turning or not, you'd have eratic revs and such with a bad fpr...chris

Was it a right turn? When you make a hard right turn all of the oil in the engine will slosh to the driver's side. The oil pickup tube is on the passanger's side. It will just suck up crankcase air when you do this.

Be CAREFUL. If you are a little low on oil, or you have a halfway decent suspention/tire setup and you can pull decent lat. G's, you can DESTROY all of the bearings in your engine due to oil starvation if you make a hard right turn. It's a flaw in the oil system from the factory, our oil pans are WIDE OPEN. That's how my 1st engine died.

No, a "crankscraper" (kind of a retarded term, it's really a windage tray) won't really fix the problem. The only REAL way to fix the problem is to add baffles to the oil pan - like a few well placed pieces of sheet metal to keep the oil near the pickup tube, while still allowing oil to somewhat move around the pan.
