948 hits the track for it's maiden spring voyage!

I agree.
At this point I would assume that they are there to compress the end plates against the core, for longer life?....or they could be used to prevent laminar flow??
If my stock rad ever dies I will be taking it apart to see...

You still need to check your fuel pressure when your running and it's getting hot. Your tune or pressure may be off just enough to cause the car to go lean on the top end. If you are truly getting the dyno number that you say, your running out of fuel at those RPM's. That's what happened to Gene's car at that exact HP. This is the fastest way to kill a motor....................... If your car is running cool all the time except on the track then there is something going on at that very moment to make it get that hot internally, It's not just the radiator causing this problem.

Showing proper A/F ratio's on the wide band at WOT on the track through out the session.

What fuel pump did you put in Gene's car?

My LS1 944 got to go on its inaugural track run today. Open track event was scheduled today but I only got to run 1 hour because of work. The one hour I got to run was one continuous hour though. I saw absolutely no issues with the powertrain. Airtemps were 85F and my water temps ran only 200-210. Oil temps to 230-240F. No heat soaking issues, no powersteering overheating, etc.

The power was deceiving - I was used to riding the boost curve of the 944, but this car keeps going. The old turbo 4 would run out of steam and adding throttle gained very little. On this motor the throttle adds more unexpected power. Very pleased and I can't wait to get back out there.

BTW I'm running the 044 fuel pump as added insurance
