Well...took the car out for her first track day at Dominion Raceway that just opened up last year. Any way, if you saw my post in the internal motor section, you know how this ends, but the car felt great, it was my first time on r comp tires and man, that was great. I got through my 1st session check ride for solo and managed a 1:41.5 in my second session before the motor destroyed itself. 178K on the clock, so I can't complain. The track is still quite bumpy, but it was a fun course, looking forward to getting back out there after I I Get a new motor.

My thoughts:
It popped from oil starvation. You were unnecessarily winding the engine out to the limiter in some spots. The stock wet sump oiling system doesn't like extended periods of high rpm. This, combined with the extra grip from R compound tires caused it to starve really bad, which smoked the bearings. Once you had metal on metal those temps skyrocketed.
For the new engine, call up Improved Racing and buy everything they sell. Pan baffle, crank scraper, and oil cooler. They also recommend Melling oil pumps, supposedly they cavitation less at high rpm.I would also add an Accusump for extra insurance. Keep the RPM under 6500, use a high quality synthetic, and the new one should live a long happy life.

That makes a lot of sense...the one lap I was trying to see if 2nd gear was better for the little esses and then where I passed the vette, it seemed like a waste to shift in fourth so I kept holding 3rd. Lesson learned. Motor had 178K on it, so it's not terribly surprising.
Thanks for the tip on checking out Improved Racing...will do.
Keep the advice coming...much appreciated.

I have a lot of laps around Dominion now, both as a driver and an instructor. I didn't like it at first, but its started to grow on me. when you're ready for the Improved Racing stuff hit me up I can give you a discount code for it. I have all their stuff in my car and they help me out. I think I'm going to ride up there this week when the One Lap of America guys stop there, I have a lot of racing buddys that are running that this year.
