Mine was at one time 1111hp. I dont know if it is more or less than that now. I dont usually have all the parts on it, as I usually keep it around 550hp and its very fun to drive with that much power. But I did buy all of the parts for it to do Test Course stuff, and thats when it was 1111hp.
for the plyphony digital cup i tried out the viper for a bit. the car had very mushy stock suspension. i know how awesome vipers are in real life, so i couldnt believe this was very accurate. this made it frusterating to drive.
i compared a mildly tuned z06 to a stock viper, and the z06 wasnt only quicker, but much more fun to drive. i think this was with the z06 a bit over 400hp. it probably was with only an oil change and racing exhaust.
i may take a skip barber car control clinic in the future, so i will be able to judge a stock viper myself .
