Western Members - Is this calculator right?

http://www.mk5cortinaestate.co.uk/calculator4.php

according to this I'm @ 375 crank!! ?? That's hell of cool lol.

Who knows the real calculation from wheel HP to crank?

according to this thing, im @ 557 at the crank...

"It is impossible to calculate these values accuratly, this information should be used as a rough guide only."

According to that I was at 590 on my last car

It's a little on the high side give or take a few. I just cross referenced it's math with one of the Wallace Racing ET-MPH-HP calculators.
My last SS dyno'd 316/325
Your calculator says 370 crank
Wallace says 358 crank (based off actual ET/trap/weight)

You have rw hp/tq #'s in your sig, who cares about crank hp?

because when kids, or people who know NOTHING about cars asks "how fast is it?", I can tell them 850 hp and 900 tq ;) lol

If someone asks me how fast my car is, I'll generally show them a timeslip or quote the time on the slip, I won't tell them how much power it's making, but that's just me...

This calculator produces results that are too high...
