Chasing a 993C2S race car. It’s nice and loud.

@zbomb ive only tracked/autocrossed my corvette and a bunch of dumb Hondas. Can I do 1 track day in my C4S safely?

disclaimer, I'm a slow idiot and I don't think my reflexes are fast enough to starve an engine

That's a loaded question.

1. Primarily - safety is up to you on track. If you are risk adverse, it will serve you well.
2. My opinion - if the car blows up on your 1st track day - it was going to do so anyway at some point in the near future be it on the road or the track. So, go for it ! The cars (as you can see from the posts in this thread) are pretty mega on track... sneaky fast and to me, really easy and forgiving to drive.

I'm another slow idiot. I did 3 HPDE events in mine and found metal in my oil filter afterwards. My first HPDE was my first time ever on a track and even I was able to starve my engine during at least one of these events.

What did you do to prep your car for the track?

Im now convinced its the wing that makes u fast.

I'm convinced it's my good looks and vast intelligence.

Guess we're all free to have our opinions.

Jason,

​​​​​​What are you thinking for off-season car enhancements? You got that suspension completely dialed in!

zbomb

The list is long - what I will actually accomplish is unknown.

GC996

I hear you. Long and expensive.

Brake fluid and the standard PCA pre-track inspection at an indy. I also made sure the cooling system was up to snuff.

I did not install a deep sump, UAOS, swap in Driven racing oil, etc. These were first time lead/follow HPDE events. It was my first time on a track and I was just trying to learn how to drive the car properly. I didn't think of it as "going racing". While I knew an oil starvation issue existed, I thought it would only be a factor in orange or red group racing situations where you're pulling more Gs.

Tough to guarantee that the 3 HPDE events had anything to do with the metals. They may already have been there from wear and tear over time. However, if you changed your oil right before each event, then there is a pretty good clue that you have some internal wear and tear happening relatively quickly.

A lot of variables such as last time you changed your oil, condition of oil, condition of your bores, service history of the car, previous owners driving habits on the street and/or track and therefore engine condition and weak links can all play into it.

If it were my car I would do the following:

1. Get your oil tested now before you change your oil to start a baseline. This will tell you what's floating around in your oil, as well as provide clues as to what components are wearing.
2. Get your car into your Indy and have them take off your oil pan to see what's in there, as well as check the oil filter for more fragments.
3. While your pan is off, get your shop to scope your bores to see what you got for bore conditions.
4. Don't know what oil you run, but the oil test, pan analysis, bore scope, will all tell you if you have a problem brewing or not, as well as what oil you should probably be running. LN Engineering provides a boatload of info on their website on the different types of oil you can run based on your situation. I suspect your Indy has suggestions as well.
5. Make sure you change your oil in the spring after you take the car out of its winter hibernation. If you are planning on tracking your car, make sure you have fresh oil in your engine before the event, and then immediately change it after each event. Lastly, change your oil before winter. There is a theme here...fresh oil often.

If you want more info on how to prep your car, just let me know and I will gladly tell you what has worked well for me from 2004-2018 and what I am doing to prep it for the 2022 season.

But right now, you need to start a baseline of seeing what's inside your engine so you can take the appropriate next steps to facilitate engine longevity for the street and track.

These engines are very durable on the street and track if you do the right things.
