[blackcobra]

Just picked up this car 2 days ago, fells strong and pulls like hell. Any guesses on my RWHP with out the NOS? Heres my sig.

 

[UpRise_5.0]

Id say around 275-300 RWHP

 

[Schlodes]

292 RWHP and 327 RWTQ

Yea I would say around 300 rwh not including the nitrous...but its really hard to guess horsepower, just throw it on the dyno then know for sure Nice combination though, sounds like a awesome car.
