Las Vegas Outside Road Course Lap Record

[@Roadracer7676]

Are you able to keep it cool? I have a 2017 Z06 and even with upgraded cooling it pulls power after a few laps. The suspension is rough and not my favorite either. Could you share your suspension set up? And how it rides on the road as well? Any info on your build would be greatly appreciated!

Have you bleed the intercooler system really good? I have the lg cooling kit and have zero over heating issues. Also e60 now which helps a lot. The hood vent is huge too

@@ClaytonYatescarenthusiast Bleeding helped a lot! I don’t get limp modes anymore. Oil temps still get near 290’s though. And I do feel timing being pulled after a few laps. I only have Prospeed oil cooler, heat exchanger and 2019 automatic radiator. Coolant is good now.

What seats are you using?

@Roadracer7676 290 isn't too bad. I mean it's hot af but I see 270 after 2 or 3 laps. I'm never doing more than 3 laps cause time attack just no more pace in the car after 2 flyers. The hood vent would probably drop 5 or 10 degrees. Also fender vents with just holes in the liner make a big improvement. That factory duct that goes from the radiator to the hood is bad news. Without a doubt take that out. There is wind tunnel testing on that allow and it picks up significantly in front downforce meaning air is extracting much better. If you don't want to cut the hood and add the race louvers hood vent then start by just removing the plastic duct. Gm even admitted that caused worse air flow but it directed heavy rain water away from the engine.

@@ClaytonYatescarenthusiast Thank you so much for the detailed replies! What seat are you running? And suspension? Is it decent in the street still, or pretty much no.
