Drag strip = consistent hp calculator (reaction time is not additive to E.T.)
Dyno = false positives ( can't tell you how many times I've seen an 800rwhp truck go 12's esp. Dodge guys) you read in diesel power all the time about how a truck makes 750 or 800 hp on dyno but will only go low 13's or 12's. My buddies bone stock lbz ccsb with a tranny, lift pump, stock tune, and 285 bfg's went 12.90's. Nowhere near 800rwhp.
