I have a 2001 Roe Viper. HP increases start at idle. I don't know about Paxton making more hp, except on a dyno. A 700hp Roe system seems to be equivalent to a 900hp Paxton - at the drag strip.
My 720rwhp Roe (10#) is with stock heads, so it could build a lot more power with ported heads. I could instal a 12# pulley for addittional power ... or just turn on my Nitrous kit. My car went 10.5@139mph in the quarter mile on stock tires, NO Nitrous. I get 25mpg (imp) and put on a lot of miles driving. I've never turned on the Nitrous since there is no where it can be used safely.
You need a roll bar to go 11.5 at the track and a funny car cage to go much faster than that. The safety equipment needed to use a Paxton or Roe with high hp would completely ruin a street car and cost thousands.
The Paxton requires that the front (top) crossmember be cut out of the car, the Roe doesn't. The Roe is a simple 6 hr. instal. The Roe looks great on the engine.
Most of the Paxton's I've seen here in BC make between 505-695rwhp.
Whatever you decide it'll be great, and too fast for the track. You'll be happy.

just wondering if the price on that will be worth it ... have any idea on what the entry level one is worth and how hard it is to tune. Thats one thing I do know from working on turbo's since I could pick up a wrench ... they are not usually reliable everyday drivers .... you are changing fuel and boost levels all the time ... see with a supercharger ... the variables are much more simplified ... your car climbs in RPM ... your boost does the same ....
