confused dragonV8.........Dyno run

Had my EF XR8 Auto, dyno tuned for the first time in it's life.

Only things i have changed from standard are:
K&N airfilter
Pacemaker 1 5/8 headers with twin 2 1/2 ss mandrel bent system.

Peak Power 175.8 HP at the wheels.
Dont know what the loss is through an auto box, but i know it's more than a manual.
175.8 HP / 1.34 =131.19 KW(think that's correct).
Did not do one before exhaust mod so i don't know how much i picked up.

Not sure whether to be :s6: or :sad: so i'll just be

I do know my new lowered suspension makes me :s6:

1hp = 0.742kW
on dyno dynamic dynometre:
Auto loss is 33%
Manual loss is 27%

So EF XR8 AUTO 170kw stock: 170 X 0.33
= 56.1 Kw loss
= 170 - 56.1
= 113.9 kw at rear wheels for auto

So in your case generally 175.8HP at wheels is around 175-180kw at engine.

So your lookin at bout 117-122 kw's at rear wheels.
