I did the FVD Brombscher deep sump upgrade. It's the most beautiful piece of aluminum you will never see.

You have not been paying attention, Mr. Ireland.

In addition to the deep sump pan and baffle upgrades, some folks do this:

The web site of a very well-known Porsche engine builder offers the following sage advice specifically for the M96 engine:
Those that want to keep their engine alive on the track should couple a proper race oil with higher volume scavenge pumps, better oil control baffles and a higher volume oil filter.

Now you guys have me scared....do I even put my car on the track without an oil baffle upgrade?

Haven't paid just yet.....

I don't plan to drive crazy on the track, but I like to have fun!

Dot legal race rubber and long sweeping bends could starve the oil just enough but otherwise you should be OK. Might wanna do an oil change before and after as well if you're paranoid.

Also you may be smoking depending on the state of your AOS.

Either way, I would put that microscope to use after your session.

You most likely will not sustain high G long enough to cause oil starvation in an autocross.

Seem significant discount, depending on parts needed, if you go to Canton directly

I think tons of people track stock 996s, but I wouldn't go beyond extreme high performance street tires without other upgrades.

Sneaky Pete

Exactly. I ran Sumi's and MPSS. Had a blast with both. It's when I went to Toyo 888's is when gloom and doom happened.

I wouldn't think twice about tracking with street tires.

My understanding was he was thinking of going to Blackhawk Farms, which is a road race course, not autocross.

Also, if you get the deep sump kit, be sure that you install the sump pickup extension. There was a thread on here from a couple of years ago where someone had an engine failure because he installed the deep sump, but then did not install the pickup extension. So, instead of fixing the problem with the oil starvation, it exacerbated it.

Ahsai

Yea, I remember that thread. Poor guy.

We ran with lots of stock 996's, 986's and 997's this weekend. Fairly flat track. Nobody had an issue and I never did after multiple events prior to my baffle upgrade. But, starvation could happen anywhere at any time on any track I suppose.

I spoke to a guy that lost his motor in his stock Cayman at Daytona due to starvation. He dropped in a nicely upgraded track motor, went back to Daytona and crashed it. So there is always that guy. Not sure if he is still married or not.

So THAT'S who has been driving up prices on M96 cores...

alpine003

Mainly on long left hander high speed corners with high enough G's(mainly race rubber) that will starve banks 4-6. Adding second oil scavenging pump and the appropriate crossover tube will greatly reduce this. This was a ROW option for both 3.4 and 3.6 motors. We unfortunately didn't get that option as Porsche assumed us dumb Americans only like to go fast in a straight line or pu$$y foot it around corners.

So last night I put the front track pads on the car and bleed the front brakes.

So is it normal to remove the calipers to change the pads? I thought this would take seconds with the Brembo brakes....but it took me a while on the first side because of the anti-squeal pads attached to the pad. I ended up removing the caliper to get the brake pads out.





The track pads had the anti-squeal devices in the box that I received them in, but they were no longer attached to the pads. I put them in the calipers, put the calipers back on, then just inserted the pads back into the calipers and buttoned everything up.

When I un-do everything, I'll have to take the calipers back off to get the street pads back in.

I will do the rears tonight, do I need to take the calipers off for those? The rear track pads have no anti-squeal device, but I saw in the manual that there is something for the rears, more like a little star?
