I will be taking the Camaro to the first Optima Ultimate Street Car event at Thunderhill on February 28th. I am making a few changes to the car to get ready for the event.
The light weight hood I have been running does not have vents. At about 125 mph the hood starts to shake from under hood pressure. At 130 is gets worse. At 140 - 155 is it out of control. I just installed some ACP carbon fiber vents to help remove some of the air pressure that builds up. I may need to go bigger, but I will try these to start. Thunderhill top speed on the front straight is in the low 140's for me.
I also corner weighted the car again. I changed the transmission bell house from a stock Corvette aluminum unit to a steel scatter shield. Safety added over 40 lbs to the car. The aluminum bell housing I had on developed a crack.
I just ordered door glass for the car, so that is going in next.
