Womp Womp noise after track
I'm not sure if I'm being paranoid, but my BRZ has been making womp womp noises at higher speed. For background, this started (or at least I started noticing it) after my first track day. At first, I thought it just be my car making sounds post-track. Perhaps tires?
Do you think it could be a wheel bearing, CV joint, or alignment issue, maybe related to hitting a tall cone or two? Or maybe it's a wheel weight balancing thing? For background at some point during my first track day, I did hear a pop sound. This past Thursday, I didn't really hear the womp womp noise on track too often as we were at lower speeds, but occasionally I could hear the sound. Lastly, some FRS/BRZ enthusiasts were recommending that I upgrade the oil cooler and/or run thicker oil to avoid blowing my motor. Do you think that is necessary? I am not planning on tracking it in 100+ degree heat for a while. I primarily use this as a track toy 1-2x/month and drive it to work maybe 1-2x a week. I am currently running 0W-20 Full Synthetic Castrol or Mobile 1 (I don't know which brand, as the previous owner changed it). Thanks! |

Yes, everyone says an oil cooler is a must for track days, and i have been recommended to go up to 30 weight oil.

Just a few questions, are you using the same tires for the track and for daily driving? If so then that maybe your problem.
Are you still on the oem tranny/diff fluid? If so you might want to upgrade to some better I oils. As for the oil cooler, I really don't think it's needed. Your not forced induction. If stock WRX's run fine all day at a track your car will do just as fine. I driven my turbo mr2 in 100 degree out in Willow Springs and it did fine. People are so worried about taking their car to the track when they shouldn't. If your car is in perfect running condition, you'll have no issues. Now some people do the mistake of not checking their cars at track so if it's starts to over heat they just keep going when they should stop and wait a few hours.

I have an UEL header and a tune but I'm not FI. Granted VIR is a track where you're at WOT in 5th gear in 3 different sections. But I would say, if you intend to keep the car long term and if you're doing more than 3-4 track days per season, getting an oil cooler is really a good idea and I would highly recommend it. I don't care what the STI does, when run hard without a chance to cool down, the twins have a problem with high oil temperature. I used to think just changing my oil before and after every track event would be sufficient. But after VIR I changed my mind. If you're cooking the oil at those temperatures during every session for 2 days in a row and then driving home afterward, I think it at least has the potential to do some damage. I can understand why people don't want to take this step. It's not exactly cheap and if your car is still new it could lead to some warranty issues. But it's better than the alternative. Since installing a Perrin oil cooler I've never run over 235*F. That said, if the car is your daily driver and you're driving in colder temperatures, it should probably be blocked off during the winter. I've noticed on cold mornings, just cursing in 6th gear, temperatures were actually too low (~165*F) and that, combined with low pressure, can also have adverse affects. |

For thw Womp Womp sound it could be just a wheel balancing weight came off. Check around the inside for a clean spot where a weight may have been

Agree the womp womp noise could be from rubber buildup on your tires. I'd check there first.
About oil temps, you probably need a data log from your track day to tell. I was seeing 280 plus on the track. Installed a relatively small Perrin oil cooler and haven't gone past 240 F since. Btw there are some who will say 280 plus is ok for synthetic oil, really just depends what you're comfortable with.

Yeah, I originally figured it was a rubber or wheel weight balancing issue, but then just started getting paranoid. I will go check it out with a flashlight (unfortunately do not have a jack or lift at home). Do you think it could be a wheel bearing, CV joint, axle, or alignment issue or probably not? The car has 42K miles. |

Update: it was an alignment issue, toe was off, even though it drove straight! Also upgrading to Motul diff/tranny fluid.
