I was wondering what is the highest temp you should race your car at before shuting it down?

Actually, the safest thing to do if your motor does overheat is to try to keep it running so you still have water circulating and if possible to keep it running while somebody pours water over the radiator.

I asked Steve Hendren the same thing a few weeks ago and he said on a high compression engine he would not run for extended periods @ 220 or higher, and especially without an oil cooler. What i got out of it was the oil temp will be 40-50 degrees hotter than the water and at those temps it cant lube as well so it doesnt protect the engine thus causeing damage. So i think tht depending on the engine it may not damage heads or gaskets or anything but will cause accelerated wear other places.. At 250 I would say you prob will hurt head gaskets, heads, etc..

Just mny opinion.

Maybe Steve can get on here and go into more detail.
