Has anyone run a Special Edition built or converted NA Subaru powered Speedster or Spyder on a Chassis Dyno to see what the actual wheel HP figures are? I was thinking of running my Speedster on a local Tuner shop in Louisville Ky's Mustang Chassis Dyno. I have tested and tuned other cars at this shop and they are very easy to deal with. If someone has run some chassis dyno pulls on one of these cars with the EJ253 Subaru SOHC NA engine with variable cam lift rated at 173HP from the factory please post what HP numbers their car made.
Does anyone want to say or guess what they think the wheel HP will be? I know it has to do with the amount of power loss the transaxle causes. Does anyone know what the average power loss is for the Type 1 swing axle trans. 15%-20% ? I will schedule a session in the next couple of weeks once the cool dense air temps. of fall arrive. I am guessing the actual wheel HP of my Speedster will be 145HP.
