oil temps
Mine goes up 135c or so after a 3 or so hot laps as well. I haven't been to the track in awhile but when I was tracking regulary it would do that every time.
It would pretty much stay there though, not get any higher than 138c or so.
This is with 340ish whp on a mustang dyno , with a track tune, with a green. I would rev to 7900 or so if I needed the gearing.
At the time I had stock radiator as well. My water temps where always fine.
At the track I used a cocktail of 15w-50 and 10w-30 redline motor oil.

how has your motor held up?

I do have some leak down now but I strongly believe it's head related, a valve seal or something as I do rev the **** out of it and it still has the stock valvetrain. Time to upgrade.
The Evo 9 we ran at the last buttonwillow TA that got 2nd place in street makes 365whp on the same mustang dyno, with a green, revved to 7900 or so if needed. Stock oil cooler, upgraded radiator. Full weight. It also hits 135c+ oil temps.
From an artical I saw some time ago: Oil's " effectiveness" is constant until about 220f, and for every 10* increase in temp an oils ability to maintain its lubricating effectiveness is cut in half... so by 240*f an oils effectiveness is cut to 25% of it effectiveless at 220*f.... I think thats whats been asked and it loosly fits with what has been expressed in the last 5 pages..Just sharing what I base my judgements on oil temp on.. I am sure there are exceptions to the rule and someone oil is better then someone elses...but for all the rest..this is what I use to be sure I don't have a problem.

With a Petroleum oil, that is correct....225 is upper lubricating limits.. AMSOIL will continue lubricating well beyond that..
I am still leaning toward a faulty guage, sending unit or something other than 290 being the oil temp especially when it is a sudden jump in temp... oil just don't jump 80 degrees right away when you hit the throttle.
I have hit over 270 on my bike, but we are talking an air-cooled V-Twin riding at 5 MPH for 11 Miles with the Ambient temp close to 100 ... No air circulation and still only 270..
Doc
you & doc say to run thinner oil but all my racing buddies along with most EVO race engine builders (like Buschur, DTM) say to go with 20/50....
im gonna try the amsoil 20/50 TRO next... then after that I'll try the Amsoil thinner weight..
