trans am easy...i beat a stock s2k a while back on 10 psi but i got pulled like a jimmAy by a i/e LS1 T/A the other night. It won't even be a race....the S2000 only dynos like 200 whp stock and weighs 2800 pounds, the hp to weight ratio tells the story, not to mention how much more torque the ls1 puts out.
