RWD tend to lose about 12-14% from the flywheel to the wheels
4WD tend to lose about 24% from the flywheel to the wheels

when i had it at 392 FWHP with the rb25 in, I threw 100hp of NOS in it and on abbey's hub dyno it made 581 lbf at 3,500 rpm:eek:

And yet on RSP's dyno it made 392 at the fly, so my reckoning 392- the %= roughly say 330bhp+ 100hp of NOS= 430 AT THE HUB, so how did Abbey's hub dyno show 581lbf?

the problem with dyno's guys is every one will read slightly different so as i was told start with one and finish with the SAME ONE!!
