Brad, I was kind of thinking that he just came from the pit out?

I had thought that it seemed that he over cooked a few corners at the entry point....but since I've never had my Z on a track I didn't feel I had any standing to critique his effort. The pick on the porsche was fair game IMHO, and the pass on the Merc could have been that the guy in the Merc wanted no part of "the mad man coming up on him"...?

Becareful Brad, HPDE's and / or track days can be more addictive than crack. MHO, road racing is waaaaay more abusive to a car than 1/4 mile work. Specially when you are using a street car to do the road work.

JMHO. I have no hard experience with an LT5, but I question the long term effects of cornering G's on the oiling system's performance with respect to pick-up starvation. I saw first hand what track days did to my 72 LT-1's drive train. I also have a group of crusin buds that have become addicted to track days. These guys are using mostly C5's and C6's. There has been some carnage in their ranks with their LSx motors, except for the C6 ZO6 guys. They don't yet seem to have had trouble, maybe it's the oiling system in the LS7?

I wanna go with them in the worst way, if for nothing else than to get the instruction and all the knowledge that the instructors wanna pass on.....but I know me, I'll get addicted and be worried about the motor...heck the whole car would worry me.

Tom are you aware that our cars have special baffles in the oil pan to prevent oil starving the cars in high G-force situations just like pure race cars do. Thats probably why they take 12 quarts of oil. I don't think I would worry about the Z breaking because I swear the harder I push mine the more she likes it and the better she runs. The LT5 in my Z has never let me down and runs flawlessly at WOT and purs like a kitten while idling at the stop lights. It's always seems to be the external B.S that breaks on a ZR-1 but never the LT5. It's just an amazing engine. I would worry more about looseing control and smacking into the wall.

i totally agree about the worry factor about abusing the car. and you are right about that guy being a mad man,either that or he is a taxi driver in manhatten .some of his moves remind me of cab rides from kennedy to manhatten those guys are truly nuts

[tomtom72]

Brad, I hear ya about the NYC cabbies! Danny Sullivan... I also hear what you're saying about beating on our motors. I know if my Z spent it's whole life driving around in suburbia where I live, the car would run like crap! She never runs & sounds better as when I take her to the upstate NY back roads & thrash her thru the two lane twisties....and that's a mild thrashing at that! NYS Troopers are sneaky people...

Rick, I was under the impression from my parts CD that the 90 pans are the least baffled. The 91 pan seems to have more than the 90 pan, and finally the 93-95 pans have left & right side baffles, and fr & rear baffles. All of them have a windage tray. This is what I get from studying the parts CD. I should admit that I've never actually seen the inside of an LT5's oil pan. Oh, and I never actually taken my 90's pan down & looked inside it.

Ya know I was thinking that I should go re-read Lee's thread as there might be something on the oil pan in that thread.

The C5, C6 and C6 Z06 all have baffles incorporated into the pans. Still the C5 had an issue with oil sliding around to the edges of the batwing design. Chevy revised the pan for the C6. It still has some oiling problems on extreme sustained G corners. The C6 Z06, also has some oiling issues, but their main issue was with capacity, which has been fixed by GM for 09 with a larger reservoir.

The LT5 loves to be abused on the track. I let Dwight use my car this past summer for an event. I got booted off the track with my race car after my second session, so we started double stinting my car with no issues. Do not be scared to track these cars. Just be scared of your ability.


As far as this guy, he has good control, but he is hot into the corners, and is tearing the hell out of his tires and losing time as he does it. Smooth and consistent.

Does it sound like his ABS kicks in under braking almost regardless of how fast he's going when he starts to brake? I wonder if he's got a pretty serious brake upgrade going on?

Pretty neat video. I have no standing to critique his driving. However, I can say I'd have a hard time being 10 inches off the bumper of the car in front of me, while burying the gas pedal into the carpet!

i dont have the ability to do that kind of racing. guess i have allway been a drag racer at heart. can hardly wait for the 20-21 at famoso. with the ugly weather time to go work on the car. love to watch the videos though(in car)

Jeff........don't tell me that an LT5's oiling system is up to road work.....because I'm addicted to road racing without ever actually doing it. You're gonna make me go get a helmet,......and do other foolish stuff.......or at least consider it, strongly...

For real, I'm miss reading the parts CD????? At the P/N side it lists mod yr application & quantity if necessary....Baffles, baffles, my oil pan has oil control appendages????

It is up to snuff, other than the oil cooler which has been debated here in the past.

Here is the shot of a late model pan.

The LT5 can handle the G loads. I have a friend in the Chicago area with a stock 91 that has at least 25k miles of solid track abuse and it's still running fine. The trick is to keep enough oil in the pan. You start a weekend one quart over full and never let the level go below full. 300 track miles later the level will be back to full.

My 91 has at least 5k track miles and it's just broken in.
