Greetings,

Go to www.dragtimes.com and follow the link to the horsepower calculator.

Plugging in 14.7 e.t./96 mph/3,250 lbs. as-raced weight (car, driver, gas) = 213.32 hp. Pretty much right on the stock HP rating !

Plug in 14.3 e.t./98 mph/3,250 lbs. = 229.20 HP


Pretty darned close to the claimed HP of the S.I. chip upgrade.

Probably be tough to actually turn that kind of e.t.s given these car's traction control systems and shifters but I'd bet the mph numbers to be right on. Top-end mph numbers are a better measure of actual horsepower. Speed/weight/time/distance is how horsepower is calculated after all.
