"Racing" is expensive.

This is where I harp on people about building a car for cooling. For track, cooling should be a HUGE focus if you want it to last. That is why my S2000 is setup the way it is.

I could melt down a stock car pretty quickly. I've ridden passenger in some stock cars with novices and even they were overheating their cars.

I'm aware, thanks.

I'd feel my car is pretty well prepared. My issue is after the headers got put on the temps jumped drastically. That's what I'm trying to figure out.

a simple test would be to put your old header on just to verify that is the issue.

if you have done that, and I missed the post, my apologies.

Yup.

As currently set up, with the stock header I could run 20 minutes last season without worry for oil or coolant temps. If it came down to paying close to a grand for heat shields, I think I'd just put the stock header back on.

Totally -- and something I've thought of. Issue was I took the time while the car was down to switch intakes and add an IAG AOS. So I'd need to get retuned again for the stock header.

You can wrap the header instead.

I think that's what I'm going to do.

I was shying away from it as Killer B was recommending not to, but at this point I'm not sure what else to try.

Many killerB headers installed including mine have seen no or marginal increase in oil temp so it has to be something else causing your problem. Faulty oil temp sensor maybe ?

If you look a few posts up, sensor has been confirmed to be accurate. Reads within about 5-ish degrees of a high-end IR thermometer.

I'm curious about your setup... so far I haven't run across anyone who is running unwrapped, uncoated headers who is monitoring oil temps and has seen no change since the headers went in.

If you wouldn't mind sharing, what are your mods, usage, and normal oil temps? Headers uncoated and unwrapped?

It could certainly be something else. But I'm really leaning towards the headers as the temp change happened immediately after they went in... that and that no one else seems to have any idea what else could be causing it.
