I'm not even really racing though... I just want to be able to run a full 20 minute track session in a stock motor, stock turbo car with headers and a downpipe without having to spend 60+% of the session doing cooldown laps.
"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.

It’s impossible to run straight 20mins even on a stock car. Those that do it aren’t monitoring.
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.

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.

I have uncoated and unwrapped IAG spec GTSpec EL headers. I’ve been monitoring temps since my gauges went in at Stage 2 through a sandwich plate at the oil filter with the wire routed up to the block back to the firewall. This was 4-5 years ago now. The headers went on 2 years ago. The headers and the EWG with a retune was the only thing that was done at that time. There were zero changes in oil temps. I haven’t done anything to the car since then, temps are still the same since I was Stage 2 five years ago.

Normal temps are around 95C (203F), roam around 100C (212F) on hot days, and go up to 105-110C (221-230F) during heavy driving or autox on 30-40C (86-104F) days.

I have uncoated and unwrapped (KillerB ELH + custom UpPipe), Invidia CATTED downpipe and 3" Borla catback. Oil temp sensor installed in a oil filter sandwich plate adaptor.

Normal Oil temp is around 190F and I have never seen it goes over 200F (spring time outside temp). When I have Oil temp at 190F my Water temp is usually around 200F. I have a conservative tune with peak wheel torque of 320 lb-ft and peak WHP 295.

Wow that's different. Stock my car would hit 200ish around town.

I do live at 6500 ft which I imagine makes a difference.

Does the car see track use?

Appreciate the reply.

That sounds fairly close to what I see around town... a bit lower but not too drastic. Do you track the car?

I have heard the Killer B ones should run hotter than other EL designs due to being a 4-1 design. I'm also wondering how much effect elevation is having as I live at 6500 ft. I know that will make cooling harder, but I'm not sure by how much.

This car has only seen autox. I’ve never been willing to push this car on a road course on the stock cooling system. It doesn’t help that I have to travel 2.5hrs one way to the closest track.

I’m right at sea level.

It's my winter car, it is parked and stored in the summer so no track use :lol::lol:
