Wouldn’t your Flywheel HP be more like 220?
Although putting wheel hp + adding my weight to vehicle did give me really accurate times. 165whp 3000lbs auto 7.9sec and 195whp 2950 6.9sec actually pretty close to my own tests.
Did you add in weight of driver and or gas? Curious if you ever weighed your car with full tank + you in it. Some times listed curb weight is iffy if it includes gas or not.
Maybe 2700ish lbs with 220hp would be more realistic? Prob similar times though.

Yep you are right about the flywheel being the stock hp #. Personally I think the calculator is more accurate using WHP.
I know Stock C5 Corvettes are right around 305 dynod Whp and weight 3250-3300 lbs, with a 0-60 around 4.9. Using those #'s the calculator is dead on.
Using stock C5 hp of 350 flywheel lowers it to 4.4 seconds which seems a bit faster than it is.
Good points though didn't add in my own weight to the car which would make it 2500lb + 170 = 2670
Good question if manufactures add in the weight of a full tank of gas to there #'s I would like to know that. A gallon of gas is about 6lbs
Haven't weight my car but used an accurate shipping scale to weight each piece removed, or compared lighter pieces to heavier stock pieces to get my weight of 2500lbs (Using stock weight 2774). I will post my data sheet when I get home from work.
