Problem is the stock automatic will loose better than 23% to the wheels without trying. The car on a properly run dyno (Mustang dyno) will show 320s at the wheels. Even if you were on an optimistic Dynojet you would only be around 365.
Basic bolt ons not adding lineraly will maybe net 50-60 crank hp if you are lucky. Don't believe everything you read is all I'm saying.

I had hoped to be able to give a break down per mod, but with the exception of the exhaust, the rest will be installed in a couple day period. I will know by seat of pants feel, but until I run for times and do the math it's just a informed guess.
The stock Challenger shows 377 HP, and 374 pf of torque at the tires. That's better then 12% parasitic loss. I would be happy with 480-480 at the tires, and that's the first goal.
