How about 10s on street tires? I bought this car in the US and exported it from there. I paid the GST and have done the Federal inspec. I haven't registered it yet becuase it could save you the $3,000 I already paid to the Gov. I have added the Daytome Running Lights and went through all the hoops required by the US and the Cda customs.
This car would drive like stock up to 3500rpm and then the Paxton starts making boost and ups the hp to 580-600rwhp. Traction even in first gear with the new tires as long as the road is good. Once you get used to the car and the 600rwhp/685bhp you can turn on the ic chiller and the Nitrous Oxide. 10s on street tires and 9s on slicks exciting enough for you?
The Paxton drives easily and with complete control (unless you dump the clutch). I attended 1 car show and took hom the first place trophy. Drove car while perfecting it (better than new)and adjusting the suspension and it drives perfect with 23mpg on the highway.
The American Club Racer is also a collectable and rare Viper GTS. The Vipers really need brake upgrades to be as good as the later models (Gen 3&4) as I did to this ACR.

Also hp numbers are misleading and not much use without a dynograph to see where the hp and torque numbers are. ie, Roe Racing TS supercharger is not for beginners as it produces massive torque at 2,000rpm and no traction, completely unlike the Paxton. Sure is exciting though.
