I'm no expert yet...but I've heard the M 90 runs 8-9 lbs stock at whatever elevation they test...probably california. Could be wrong...but I guess I'm around 5 or 6 lbs maybe...who knows. I still win! Oh and according to Intense racing I think it was...the stock pully is a 3.8. Which is freakin huge compared to the 2.25 my buddy just threw on his cobra!!
