Why did the video end when she asked you what all the metal in the filter and oil meant? Too much profanity and violence for YouTube?

Time to drop an Audi V8 in that thing!

Waddya know about that? Keeps all the gauges and functionality? Keeps the street-ability of the car?

Bummer! I agree that motor is boat anchor status now. I watched the vid and didn't see any extreme banked sweepers or super high rpm. You kept it in the 4-6k range in the corners which usually protects the 986 motor pretty well.

Our Mitigation over 10 years on the PCA Time Trial circuit:

- 5w40 Castrol full synthetic and we watched oil temps, ending the session if things got to 240F

-Oil level matters and we made sure it was exactly topped before every session.

-We added the X51 pan but no other mechanical oiling mods. I didn't like the deep sump or the Accu-sump solutions.

- We stay off the rev limiter except down a long straight. High rpm in mid corner or zinging too high on heel-toe downshifts in a heavy braking zone has taken several motors according to the data logs.

200+ track days between two 986 BSX cars and no motors lost. Whew!

Dan I watched the video and it looks like you had a couple of pretty high revving downshifts in a hard braking zone prior to a left turn... might not have helped. But other than that, seamed pretty innocent.

No, but it bolts up to the transaxle. I also believe that the engine is physically smaller than a LS small block, so there is less fabrication gymnastics involved.

Im much better at the "fabrication gymnastics" than I am with the electronics. That's my big concern.

Did you run with the stock sump baffle?

Sustained high rpm runs will damage bearings. That's why I shift at 6K rpm.

no. I have the EBS baffle installed.

but it is the stock sump.

I feel like my motor is very strong between 6 and 7k..... and not so much if I'm short-shifting to 3k. So shifting at 6k seems like a fast way to go slower, haha.

Tell me about that? 'cuz I'm assuming you're not slow.

I also have the EBS with stock sump.

I am NOT fast compared to the cars in my run group. I'm a knife at a gun fight. They all have engine & suspension mods along with gumball qualifying tires. The mods I have are to tackle the OEM design flaws but keep it a reasonable street car that I can drive to & from events rather than trailer. I will be driving 600 mi to Indy in Aug for a 3 day DE and then drive back home.

I run street tires to eliminate the higher Gs of track tires. This reduces the chance of oiling issue but gives up a lot to the competition.

I shift at 6K rpm to avoid stretching rod bolts (which leads to rod bearings slipping). Not sure if this is an issue with the 986 but definitely is with the 987. Does this cost me? Yes, but max torque is around 5300 so going to the next gear and getting to max torque in the next gear isn't that costly.

Is it fun being passed all the time? No, but I still have my own kind of fun. I get enjoyment out of driving well technically. I get passed by guys who miss an apex by several feet but they have 200 more HP than I have and leave me in the dust on the next straight. He's probably having just as much fun as I am. In the end, neither of us "wins" the DE. My approach to DE is different than most and isn't for everyone.

I was asking as I like to gather data.

You are right on track for the September DE :dance:

yup... that's my plan.

If I can find me another weekend like this last one, I think I can get there.

I wasn't supposed to have time this weekend, 'cuz my adult-kids were around...... but that's what they get for sleeping-in 'til NOON!!! hahahaha
