in case you didnt already know...

1/ Take the peak MAF reading on a FATs run (4,200 to 6,500rpm in 3rd) and divide the figure by 0.8.

2/ log the torque and use this simple formula

BHP = 2 x pi x torque x revolutions / 550.

Pi is 3.1416, torque is in pounds-feet and revolutions are revs per second.

Obviously, we can change the revs to revs per minute, easily!

3/ BHP = 2 x pi x torque x rpm x 1.34 x 10 to minus third power / 60.

For this formula BHP is in horsepower and torque is in Nm

first way is commonly thought to be most accurate.

shamelessly stolen from RS246.com

yoinked this right off dubforce.net

thought some of you could use this

Fine if you have a 20vT where you can use Vagcom or something to log the MAF readings I'd have thought...

or you could just stick it on a rolling road :p

looks confusing that does! good little find though, I'm sure someone's gonna try it out lol

RR seems to work

For £25 i'll stick with the RR, i could never work that stuff out anyway.

hmm thats annoying, I've just gone MAFless on the skyline. I wonder if the readings can be taken from somewhere else?

what bhp did you get at buglovin? or what ever it was called the other month.
