Buddy of mine with an ultra light foxbody (2600lb w/driver) was seeing almost 180mph in the eighth, so he was a little surprised when some of the more reliable online HP calculators (Competitiondiesel for RWHP Wallace for Flywheel) showed about 2000rwhp and 2350hp crank, respectively. He thought he was making more. I was like your car is light man! Anyone have a combo close to this they've actually dynoed, either engine or chassis? I'm curious at how accurate these things are.
