stock weight on the 96 Z was under 3400... with all the junk i have out of the car i figure its more like 3300 or mid 3200' with spare and misc junk out. yeah that 14.95 could drop much more with me emptying out stuff and a good cold night. the 14.81 with the DOHC was prob the best night and had all that stuff out. i did how ever hit a wet patch and spun my tires that night... you can see smoke coming off the tires and see the spinn in the data log too. also its trap speed was about 2 mph less then when i ran the 14.91 with the DOHC. but yes i am very happy with the 3800 in the car right now.
