I don't know your build, but unless that bottom end is super loose, I'm Gonna say the oil is too high a viscosity for starters. That will add to oil temps but that seems to be considerable temps. Are you sure your guage is correct ? Just taking a guess but in F., 100 C is 210 so that has to be close to 300 ? Your coolant would be effected as well and boiling all over.

Need to look into and check the guage..

Doc

 

140c is about 284f.... I let off at about 135 today but know it will go alot higher.

nothing wrong with the guage i dont think...

I tried the Thermo-Tec stick on sheet on my oil pan. Supposed rated at 2000 deg F. Peeled itself right off before my next oil change. Nothing left except the clear adhesive layer on my oil pan. Waste of $15.

 

Pick up some gold foil from CBRD and place it on your oil pan. Wrap your downpipe atleast past the oil pan.

I'm sure this would help with oil temps.

 

Ya i warned nilly away from that crap too, sticky's don't stick in the heat With AMSOIL 0w30 in the car at Barber on a stock block, and the downpipe now wrapped, looking at my docs, 99deg outside and 140ish track temp, oil went up to about 249 at it's peak, with temp sensor same place everyone else puts it, on filter housing. That was with the new oil cooler duct (plain jain aluminum sheeting formed around the c-west front end where the cooler sits). Methinks that the front pass. brake caliper, which had to be 1200+ cause my sh*t was on fire, are only about 12 or so inches away from the oil cooler, and only a thin piece of wheel-well plastic between them....mayhaps most of the problems are coming from there....but then again you got the wheel and tire between them, but is that really doing anything to help or hurt..

 

I hit 135-140c at the track as well Nils.

I need to look into upgrade cooling as well.

 

There are 2 ports on the filter housing. I think the guys that see lower temps put their sensor in the cooler return spot, the guys that sees higher put them in the cooler feed spot.

think im gonna weld a bung on my oil pan & put the sensor there.... I want to know what my temps are in there.

Oil pressure is also an issue, during HARD right hand sweepers I loose oil pressure, I know the oil slushes around in the pan .. so others must have this issue too.

 

ok when you guys are talking about 100c-140c or so, is this on the stock oil gauge?? what does the stock gauge read in?? i have never seen my stock oil gauge go over 85-90!!

 

no, pls pay attention & read the thread..... aftermarket guages.

we are talking about tracking your car on a road course, 85-90c doing that is impossible.

 

Trackday last friday at SOW. Temps were WELL over 100*F outside. Oil temps never exceeded 120*C on Mobil 1 10w30 extended performance. However, I was only out there for 15-20minutes at a time.

 

How hard and long are you guys with the oil temp issues pushing your car on track? I was at VIR this past weekend and still didn't see much over 240F, even in low 90F weather. I do shift at 6500 rpm most of the time, almost never exceed 7000 rpm, and rarely sustain revs above 6000 rpm, all in the interest of keeping my stock motor together. When I do push it, I only do so for maybe 10 minutes max at a time before backing off for a lap. I also usually am trying to conserve brake pads somewhat in the interest of economy, so I don't wind the car out on every straight. Are you guys driving 10/10ths for 20-30 minutes at a time, the way you would in a wheel-to-wheel situation?

 

I go pretty hard and don't see the sort of temps Nils is getting. Then again he is making a good bit more power as well.

Nils- Please document your Accusump install.

 

exactly where is your sensor located at?

n

 

I'll rev pretty high.... 8500 ish.. cant remember exactly. I drive hard... but this is silly, it gets hot after 2-3 laps.. something aint right or reading right.

n

 

ya, I'll document it for sure... any of you other guys loose pressure on hard right hand sweepeers?
