Would the hypergram in 18x11 +40 fit for maximum class spec? With a 285/30, square to be able to rotate wheels around.

Searched the thread but all the info was a bit old. Although EJs don't change the parts have.
At what point is everyone considering upgrading oil pan / pickup? Debating IAG vs Killer B ( pan / windage / baffle / pickup). I'm getting 200TW tires and started to worry about oil starvation. |

I say do the pan and pickup together regardless as soon as you get serious about any kind of motorsport with these engines. Its cheap insurance, and also gives you an easy port for oil temps.

Thanks for the input.
That was my train of thought. If I need to pull the pan to change the pickup, might as well swap the pan. I'm keeping this car as close to stock as possible. Motivation is just insurance for stickier tires. |

The Killer B Super G pan is the pan what I use now. I had the IAG, but the sheet metal baffle cracked in a bunch of spots. The "Viton" flaps stiffened and froze open after a few months. The cooling fins made absolutely no difference. When I called for support I was completely blown off. When I switched I stopped getting low oil pressure readings on left uphill turns. The oil was cooler. I think that's because the KB holds more oil and the pan walls are thinner. The KB pan is half the weight. I'm not an engineer but it seems like some pans are designed to work and others to market well. I don't mean to disrespect the three letter word company but it seems weird that so much of their stuff I have owned has failed, and it happens to other people too, but the fan boys keep pushing their stuff. |

I'm no IAG fan boy, and I still run a KB header, but between the two oil pans I wouldn't even run the KB on my daily driver since it falls over on 225 conti ecs tires and stock suspension vs the IAG holding up to 335 A7's with aero and good suspension. |

Is it the pan or pickup/baffle causing the difference in pressures?

The best way to put it is I couldn’t run more than 5 quarts in the KB or it would puke oil out of the iag aos. With the iag pan I can run 6 full liters (6.2 quarts) and it doesn’t puke at all. Pressure drop on the kb is measured in seconds (30 psi at 7k rpm) vs tenths of a second on the iag (40 psi at 6k). There’s really no comparison. |

Are you measuring lateral G? You'd have to get over 1.1 sustained and peaks over 1.2 to see failure on the kb.

But I've got an 05 STi I run for fun too that has a KB pan (where the comment of 225 conti's and stock suspension came from), and at an autox it would push oil as well. It was maybe around .9-1 G total, but I was on throttle everywhere with the back end lit up. The general basis is, if you're competing and pushing the car, the KB will fall down long before the IAG will. |

Is this an issue on track too or mostly just autox? |

Before I did electronic monitoring I put a camera where I could see the oil pressure gauge. The year prior I was coming off course and out of the corner of my eye I saw the oil pressure gauge moving. The next run I looked at it on course and thought I saw 30-40 psi but wasn't sure. Then I mounted a camera to watch it and saw what it was doing via the (slow to update) gauge. After that I stopped having codrivers and got the electronic monitoring hooked in and saw how bad it really was. Once swapped over the problem was mostly gone, but not entirely as I noted. Still, the few dips I see on the car are very short lived and after very hard elements. And it's not like my car is getting slower over the years so I'm constantly pushing it more. I think an IAG with a accusump would be pretty bullet proof, but a dry sump is still the final solution to oiling in an EJ. Porsche did it years ago because they realized the same thing. |

And for the record, the 05 STi is getting an IAG pan as well because I don't want to run it again while it's on the KB.

Its hard to see, especially with the FPS flicker of the digital gauge, but its there. Overlay shows G's as well. Note: I had a misfire during that track day video so I was off throttle a lot of the time babying it. What pump are you using? What sensor are you using for oil pressures? Where is it mounted? |

Watching your videos, you're probably at the threshold for starting to see issues. Not a slam, but you're not running Hoosiers, and the car is not stressing the oiling system a lot yet. The average G I'm seeing in your vids is about what I saw in my 05, but the throttle usage is different due to FWD and differential setup. You're waiting to get on throttle until the car is mostly pointed straight (as evidenced by the one tire fire stuff), while I'm on throttle before the apex. That's a key difference in EJ oil issues.
The average sustained G in my autox car is 1.5 and it'll often peak around 2.0. Combined lat/long is even higher. I have a shimmed 11mm pump, one of the standard AEM 0-5v sensors, and it's mounted in the back galley by the turbo. I've ran different sensors over the years and they're all within a few psi. |

Using my sensor at the back galley as well, the upgraded stainless sensor, 11mm pump too not shimmed. I should figure out a better data logging setup in the future though, the accesport only does so much. My next build, whenever that is, I'll try an IAG pan. |

In a world run by pointless FB groups, its so refreshing to see intelligent discussion somewhere.
