Reply to "#2241 on the Dyno"

Kelly,

1 HK is equal to 1 HP, and 784 Nm is as You say 578 lb-ft. So 618 HP and 578 lb-ft

Mufflers is the GTS style from Wilkinson, incl. the headers. So not stock.

HP is measured/calculated on the cranshaft.
The machine is VERY complicated. They do some testruns, where they spin the engine up to 3000 rpm’s a few times, and then let off the throttle with the gearshifter in neutral. Then it measures how much it needs to drive the wheels, transmission etc. for the later calculation. It should be very precise, they say ?

We did some other, unmodified, cars that day, and according to the original data, it was very precise.

A Lancia Thema 8-32: 205 HP by the book, and 202 HP in the Dyno.

A Ford Consul 2.3: 108 HP by the book, and 101 HP in the Dyno

Just for the fun of it we did run a brand new Kia, and it showed 5 HP more than the book, though.
