Trying to calculate E/T

The formula for ET is the cube root of weight/hp x 5.825. I got this from my bible, the Auto Math Handbook.

You need to have an real number for the horsepower at the wheels (not flywheel HP) and actual weight with driver for it to work properly. If not, it's just guessing. I assume at least 15-20% loss of power through the driveline, probably more in reality unless everything is rollerized and super lightweight and your gear and tires are correct for your goals.

Just for fun, let's assume your car will make around 850 to the wheels and it will weigh around 3,500 with all the equipment you need to go fast safely.

I come up with a 9.3 ET. Sounds conservative with 1,000 hp on tap, but obviously if you were lighter you'd be faster. This number is assuming everything about your combo/chassis/converter is optimized.

See these two pages for more calculators such as optimum gearing and tire sizes.
