Viper Dyno #s
People also need to keep in mind that Vipers have a 335 rear tire, and the wheels are HEAVY. I picked up a rear Viper wheel once and was shocked at how heavy it was.
With a set of lighter wheels in the back, expect to see any Viper jump up 15 rwhp on the dyno.

Last fall had a bone stock one come in when I had the above mods, and LG Pro Lts 375 RWHP... He went 12.4 @ 116 I went 11.82 @ 118, and no, he did not line up with me. No worries, great cars!

We have dynoed and tuned many Paxton supercharged Vipers that are all putting down right at 600 RWHP at 7-8 psi of boost on our Mustang Dyno. These kits use liquid to air aftercooling, a very impressive setup. That would be in the 675 RWHP area on a DynoJet.
