Shift as close to redline as possible.

Some people don't understand horsepower and torque; they are basically the same exact thing excluding the factor of time.

I've done the calculations with the aid of RPM, gear ratios, rolling tire diameter, a dyno chart, and microsoft excel. The car in stock form will always put more torque to the ground at redline than in the next gear, thanks to torque multiplication via well engineered gearing.

Thank you, come again.

I was aiming to shift around 7000rpm and did get a bit of tire spin at the start as I was figuring out the tire/track surface combo.

R/T .295
60' - 2.320
330' - 6.354
1/8 - 9.580@76.85mph
1000' - .000
1/4 - 14.569@96.51mph

Again, any help from someone who knows the car would be appreciated.
Work on your launch. That 60' is killing you. You picked up 20mph for the last 8th, so the car is okay. I would be guessing you are shifting too slow.

For the unhelpful, condescending douches out there, I am sorry I wasn't born with your bountiful knowledge of every car on the planet. I have owned Preludes, a 280ZX, and a 300ZX however this is the first time I have gone to the track. Perhaps if you could come down off of your throne and bestow upon the rest of us some of your wealth of knowledge the world would be a better place.
Two potential areas for improvement:

a. 60 foot time
b. Car is picking up only 20 MPH in last 660 feet. This may be weather related. May be you.
