+1 Hard to tell from the pics, but this 911 will see the track again.

I just saw the tail and wondered if an RSA bit the dust...
I agree, enough money can fix just about any car. Might be cheaper to part it out if its a standard C2.
Still sad to see any 964 die though.

No doubt. And even more so, as with all the racing he's done over the years, I'd like to someone to name ANYONE with more track miles on a 964 out west than him.
Everyone remember the first time they went into oil? Damn shock! Mine was an open track day maybe 3-4 events into my racing "career" when a modified 928 let loose in front of me at Firebird. No harm, but pissed me off to no end when I saw how cobbled together that car was and they let it out on the track.

From discussions years back with a knowledgeable Porsche AG race car service manager in Germany, you want to flow cool air from the 964 front bumper intake back into the wheel well in order to create positive air pressure in the wheel well itself. You can put a duct back into the well well (TechArt used to make a kit, by the way) from the front bumper (which some people call a brake duct) but all you really need to do is punch a sizeable hole (or holes, as this case appears to be) into the liner to permit air to come into the wheel well. By creating a more positive pressure area in the wheel well fed by cool frontal air, the wheel well will better evacuate the hot air from around the brake. Or so the story went. Jurgen Barth told me this personally, in case someone happens to recognize the name. I suspect he knew what he was talking about.
I just happen to have my liners out at this very moment.

"better airflow without liners" . . . . maybe, but!
Given that the standard right side/passenger side oil radiator vents out the bottom, that would suggest that bottom venting is adequate for an additional oil radiator mounted on the left/drivers side in the space normally reserved for the AC radiator on cars so equipped. Of course you also need to remember just what purposes the liners serve in being installed in the wheel wells in the first place. For sure they prevent rocks and crud from being thrown up into the fender (where they can create "star" dents like on old Carrera chassis cars) and forward into the fender well where they can damage lights, cables, radiator, fan, etc. On a track car or race car, the liners may not be needed or necessary. So you might get better airflow without the liners but you still run the risk of having the tires throw debris into the fenderwells. I could be wrong, but I seem to recall that Porsche still ran the liners on the 964 Cup cars of that era. BTW, an interesting sidebar to the auxiliary or extra oil radiator issue on the 3.6 engine is that I was also told by Jurgen Barth of Porsche AG/Weissach that they had determined the car did not need an extra oil cooler until the engine put out over 300 horsepower.

Based on my experience, I agree. Additional venting is unnecessary.

My experience suggest otherwise. I have identical coolers .... left and right. It is true that when I run with ambient temperatures in the 70s, I tape up the front venting area to reduce airflow. At or close to 80, two coolers are needed IMHO.

"At or close to 80, two coolers are needed IMHO".
Understandable. Practically speaking, who knows what air/track temperatures the Porsche engineers were using for reference when they made that 300 hp power/auxiliary cooling determination? And perhaps more to the point, I've yet to hear someone seriously argue that Porsche engineers are infallible.

I don't know. From what I see it looks like it will need an entire new front nose clip. Remove from the gas tank forward and replace. The front right looks like it is pushed down the front left looks like it is pushed up and everything looks pushed to the right. They might be able to pull it but I would rather have it cut and replaced per the factory guidelines than trying to straighten damage like that. If there was a camber truss the damage might extend beyond the obvious might even be more than we think.
Quite the shame.
