Is there any chance a similar baffle can be made for the first gens? The FA20 game needs KillerB!

This somewhat explains why it takes so long for RTV sealant to dislodge and needs hard driving for some of the bits to dislodge. If oil is ending up in the front cover area, hard cornering transitions would likely dislodge excess sealant over time.

It's everywhere in the engine! Many assume addressing the lower pan section is a fix, but that is just a small percentage of where it's used. On our development engine you can see it oozing out of places on the inside and outside. |

We've got a couple units available if anyone wants a Beta unit to try out. All it costs you is installing time. Shoot us a PM if you're interested in being a tester

Hi, just wanted to share some preliminary testing I’ve been doing to set a baseline before installing the prototype baffle. I made a video documenting the testing setup and the results:
The summary is: I can consistently reproduce oil pressure drops on right-hand corners, many of which are significant enough to cause concern for bearing damage. This is with low-grip GT Radial SX2 tires and minimal modifications. I’m running OEM coilovers, OEM ride height, and just have minor alignment changes on the front end from offset strut mounts and camber bolts. Rear end is entirely OEM. I’m also running a Jackson Racing oil cooler and Motul 8100 EFE 5W30 motor oil. The prototype baffle is going on my car today and I’ll be at Thunderhill 5-Mile on July 1 to test the baffle. |

This video needs stickied…I know a baffle would be cheaper then this. A remade oil pan and the deeper part centered with oil pick up tube? Or a deeper high capacity oil pan to insure no drop? Even if oil is getting trapped in other parts of the engine extra capacity would negate the pressure drop would it not? Or hell a pick up tube that has a bend center of the current oem oil pan?

This is a fantastic video, thank you for taking the time to put it together. Honestly, it's giving me pause on taking delivery of the GR86 I've been waiting for in a few weeks. I was surprised to see such massive pressure drops even at less intense corners, like in your video around the 10:10 mark. It's showing around 0.9g through the right hander, yet that's still enough to lose 50% of oil pressure. |

I have read about some modifications to pickups to remove bends (I believe this was in a forced induction FA20). They argued that the bend was causing cavitation and, thus, starvation. So in general I’m hesitant about bends unless they have significant testing, which seems lacking even in the factory FA24. In theory this pressure drop could be a result of cavitation in the irregularly shaped FA24 pickup rather than lack of oil, but it’s hard to say without more research. At this point, I’m hoping that the prototype baffle works and I keep can tracking this car for years to come. |
