Cobra has its fangs! Post-fix dyno #'s!!

[fixer]

hey DYNO, ifigured you'll be making 345horse with an 18%loss.first you were making 18 percent loss with the other exhaust so even still its a conservative estimate. follow me here and you'll see what i mean:
what you know for sure: 283.0 rwhp.

assuming 18% loss, 18/100 = .18 then

283 = X-.18X,

283 = X(1-.18),

283/.82 = 345 HP!

IF YOU use the same formula for the torque (also not real accurate) then we should have

287.6/.82 = 350.7 torque (lbs/ft)

either way, you're making real good numbers. this is also assuming an 18% loss with a restrictive exhaust so you might be making more. who knows, but from a car by car standpoint a good estimate would be 320-345 horse. don't even waste your time with z28, just go for those ram air t/a's and some vettes!!!
