m96 track reliability? (noob question)

[Racer Boy]

The baffle helps to keep the oil around the pickup, it's a essentially a box around the pickup with hinges on the walls, so oil can move towards the pick up when cornering, but it can't move away from it (if that makes sense).

It's a relatively easy project to do. Lots of threads on it, if you use the search function you should get all the information you need.

Mezgers dont use 4 pickups, they have a completely different case design and true dry sump

With more than 175 track days (including 80 races) on stock M96 engines, I think that your mechanic needs to reconsider his position.

I routinely get 60-80 hours of track time plus 10,000 miles of street driving out of a used (90K mile) engine before it finally fails.

I would recommend installing the X-51 baffle since its cheap and easy to install and will give you peace of mind. If you run sticky tires (R-compounds), then I'd recommend a deep sump with the horizontal baffle to go with the X-51 (see photo below).

Yes, I consider 2.5L M96 engines to be disposable, but only because the cost of parts and labor to professionally fully rebuild an engine ($7,500 to $10,000) far exceeds the cost of a decent used (salvage) engine (under $3,000). And no, there isn't a significant increase in engine life of a fully rebuilt engine vs a used engine under racing conditions.

Since I started racing, I don't baby my engine. I shift at redline and downshift at redline (and occasionally over-rev). Maintaining position is the name of the game.

What brand of manufacture is that baffle, plate and sump? Looks nice!

30+ track days on my '99 Boxster with zero engine, smoke, or oil-related issues. Running 0W40 oil, 180 or 200 treadwear rated tires for all of them.

Strong believer in the sump and baffle shown in THStone's post. I ran for 2 years before doing anything with my oil system other than changing oil after each event. It was 28 days on track. The third year I started running Dot 100-A-A tires and added a similar kit. The 4th year I went to a LN block with all the bells and whistles. I have 44,000 on that motor and easily 50 % of that is on track with Dot 40 slicks.
