2014 86CUP Challenge to NorCal with NCRC

[unsurety]

Not worried at all with the procedure of taking off the bumper. I've done it before on a few cars. But the twins have a design flaw. If a bracket was the issue and not the bumper, I wouldn't worry.

You can always get your oil analyzed because every oil act differently to heat and what not. Definitely not something I can even try to answer.

I don't understand why you're saying air cooled oil coolers reads lower. Lower than water cooled? I pull my oil temp from OBD2 so if I can't trust those numbers, then why look at them at all?

I run mobil1 0w30 and I change my oil every 5-6 track days. I'm too lazy to get my oil analyzed. Mobil1 is good enough for me and I rather know that I'm running fresh oil versus thinking my oil might still be good for X amount of track days.

The temperature readout 121 F said on saturday @ T Hill. I am a novice, but I didn't encounter problems with power. I popped my hood after every session, and there was at least 50 minutes after every session to cool down.

I was more concerned with the air cooled oil coolers because the temperatures actually read too low. I don't know if the oil will get hot enough to evaporate moisture during winter.

I'm only using Redline or Amsoil 5w-20 and change @ 3.5k (E85)

Good point, I had planned to get it analyzed at 3.5k. That's sort of early for even E85 N/A cars. I'll only have 2 track days and 2 autox's at that point. Better safe than sorry.

It comes down to semantics... by air cooled I meant a water-to-air oil cooler. Or would that be oil-to-air?

I guess it would be good to provide context, LOL. I was considering this oil cooler, which I guess would be called water-to-water http://www.ft86club.com/forums/showthread.php?t=42511

But since hot coolant is running through it, I expect it to be warmer than say, the Perrin would be. I mean, 200-220 F (coolant) vs. 115 F max ambient, right? I've read a few things saying a high grade synthetic should withstand 270-280. Under track day circumstances with ambient at 105+, maybe not. Even the driving school instructor said 270 is okay for synthetic. The oil analysis should tell me.

I think he's referring to the fact that an air to oil cooler may keep the oil too cool. A thermostatic sandwich plate would address that.

[acx23]

The way he said it make it sound like it's a concern. Like it doesn't give a correct reading.

I have an air to oil oil cooler. The sandwich plate has a thermostatic spring.

If you read through my thread http://www.ft86club.com/forums/showthread.php?t=70832, I have an oil reading of max 222*F at Laguna Seca with sub 95*F intake air temp in a mid 80*F weather. I know MRLS pretty well so I drove the car pretty hard.

Hope this helps

Yup! I don't want to have to block off the cooler for cold weather. Seems a little ghetto.

I'm actually buying the cooler from this guy (mkivsoopra) with a non-thermostatic sandwich plate. It'll be cooling all the time, without running too cold.

I am probably overthinking this, as usual.

My reasoning is I'm staying N/A and lower oil temps are better... to a point. There's the idea that short trips are bad for engines in part because the oil doesn't get up to temp, so moisture accumulates. I feel that a water-to-air oil cooler will only compound this for a daily driver. My commute is only 4 miles, too.

[acx23]

I see. You should probably go with the air to oil route since it uses a sandwich plate with thermostatic spring.

I have 2 cars and I work from home so I rarely drive the FRS. On top of that, I park my cars outside and I live in Daly City/Pacifica, and I'm less a mile away from the ocean. My car is also NA running z2 tires. Just a little background information

The oil cooler he is buying is Oil-water so it doesn't need a thermostat.

I have an identical Oil-water Oil Cooler as mkivsoopra that I am selling. Let me know if you are interested. You don't have to remove the bumper to install this one and it comes fully assembled. Like mkivsoopra, I am going to have to go to greater lengths to cool down my turbocharged engine...

@JSimon is now also in need of an oil cooler. He said he hit pretty high oil temp and the car went into limp mode last weekend at thill.

most of our fellow 86s "spirited" drivers told me to plan all the stuff u need to do to ur car that required taking off the front bumper altogether... we are on the same "never taken our front bumper off" boat

If i remember correctly, jsimon was on e85 and his oil temp still reads at 265

I will be installing an oil cooler before I go out again, fer sure. There's a dramatic difference between how the car cools at 85 degrees and how it cools at 105. The 20 degrees crushes the car's ability to shed heat. I like the idea of an oil cooler like Robispec designed. It will help with the short trips too, and the water should act as a nice heatsink for the oil. Too bad people were having the Robispec solution fail.

Duplicate post as on the Technical Topics --> Tracking/Autocross/HPDE/Drifting:


Results from our 6th and 7th events held on Aug 2 and 3 at the famous Thunderhill Raceway! Thanks to NCRC for hosting us. Special thanks to CSG, LPI Racing, and Mann Engineering for their support.


Half way thru our season and we welcome the twin-86s of @mkivsoopra and @sw20kosh. There's more than meets the eye with these 2 owners/twin 86s. @RehabJeff86 blistering 2:08 and 2:10 lap times proves that you don't need anything but practice practice practice. What does that do for the rest of us? Uh hmm yeah... we need practice practice practice. Keep us on our toes, Jeff!! Next NorCal 86Cup events, Sept 27 and 28 (Sat/Sun) will be at Buttonwillow. And I think we will have our first female driver joining us


Read up about the the Aug 2/3 tips, tricks, and comments on http://www.ft86club.com/forums/showt...=57243&page=20. Start page 20, post #440.

I spoke to NCRC and it's either ~$3K for our own session or bust. Considering that would be everyone in an FR-S/BRZ (excl school/solo). We can consider Thill or BW and invite any FR-S/BRZ from where ever region (excl school/solo drivers).

@sw20kosh - don't take it personal, I just thought this [ur] post is most appropriate for my response haha
