All,
Engine is rebuilt after the timing chain failure I experienced at Mid America last month.
Car is ready for this weekend's SCCA race at Memphis Motorsports Park. http://www.memphismotorsports.com/
SCCA has opened this weekend's race at Memphis to the public for free. All spectators will be able to enter the paddock area and walk around and view the cars and talk to the participants free of charge!
I'll be practicing about 8:45am Sat and Sun and racing about 1:00pm on Sunday.
Question: You're not going to put Amsoil in your engine straight off, are you? I don't know how you could break in an engine with synthetic oil. Also, how are you breaking in your engine or are you just going to race it fresh?
X,
I'm not sure where I stand on this. Last year when I put this motor in the car for the first time (03 crate motor), I did put a dura-blend type oil in it and ran it for 10 hours then switched to synthetic. The inside of this motor still looks fantastic.
I switched to AMSOIL at the beginning of the season, and yes I did put the AMSOIL Series 2000 20w50 right back in. But as No Doubt said, in this case, I have the exact same pistons in the exact same holes with the exact same rings in the exact same spots. No further "break-in" should be needed.
That said, GM fills the LS6 with synthetic and we all broke it in that way without issue, so next time I install a new motor, I'll likely just fill it with AMSOIL and go racing.

I know.. That's what I figured. I just heard that putting synthetic oil in a new motor before break-in would extend the break-in period because synthetic oil is supposedly too slick. Then again, how do manufacturer's like Porsche and GM, as No Doubt mentioned, get away with putting synthetic in at the factory. Hmmmmm...
Will you have any miles on your engine before you race it?

This motor, an 03 crate motor installed last July, essentially has 10 hours of break-in and six race weekends on it, so no additional break-in is really required, but I did put 17 miles or so on it during practice this morning...
Car ran strong during practice. Didn't push hard at all and ran within 2 seconds of my track record on tires that have five heat cycles on them. It was pretty hot today as well, mid 80s.
Although my straight away speed was as good as it as ever been here, and oil temp and water temp were fine, oil pressure is noticably lower than it was before the timing chain failure. Not sure why yet. It was only running 40 psi with the oil at 220 degrees. We'll see how it holds up during the 26 lap race tomorrow...
Memorial Day weekend crowd was sparse with no other T1 cars showing up. There were five T2 cars though.
I managed to avoid three wrecks and survive the race, safely slotting myself in between the GT cars and the AS and T2 cars. 12 more points puts me back on top of the Mid West Division T1 points race with half the season over.
But now I have to head up to Topeka, home of new T1 hotshoe Mike McGinley, who I found out recently was the 2003 SCCA Mid-Am champion in CSR and ITE classes. As I've only got two track sessions on that track, its going to be an interesting weekend.
Subdriver, congratulations and glad you had a safe event! The other guys are probably worried about you coming to Topeka, etc. and are fine-tuning their rides. Good luck in the 2nd half of the season.
No kidding. It's nice to have something like that when you miss two races because of mechanicals. Brad did avoid three wrecks though, so he deserved the win, even though he didn't have any competition.
Hope you guys are remembering to have fun. Winning races and gathering points isn't what it's all about, is it?
