Think the Calculator is right?

Is this thing making RWHP calcs? OR Flywheel HP???? IF Flyhweel, I say its damn close...

I punched in the best ET my car has ever ran to date, which was a 13.11 @ 102.74 and I used car weight with me as 2975 LBs [saying my car is 2700 LBs, where I think it was 2800 then with iron heads etc] and said I had 261 peak HP and 251 average HP.

Back then when I ran the 13.11, I had bone stock motor with just bolt ons. 65mm TB, bored stock MAF & a K&N cone, Mac equal length headers, stock H pipe, Dyno Max 2 1/2" cat back, underdrive pulleys, timing bumped to 15*, smog bypassed, underdrive power steering pulley, FRPP alum DS, 3.73s, slicks...

Just looked around on there and didnt see anything about it being RWHP...

Also, if you ran 14.48@ 96.2 MPH and the calculator said you had 229 HP, I would venture a guess its not only accurate but that its flyhweel HP, and here's why.

I have a Car and Driver here from 1989 where they did a test of cars that were under 10 grand and it had the LX hatch in there... and they got it to run 0-60 in 6.2, 14.6 @ 95 MPH in the 1/4 and voila... HP rating is 225 and 300 ft lbs TQ in the mag.

That has got to be flywheel horsepower...I would say you have 200rwhp...and could get a mid 14...
