Here is some pure facts for everyone. I have a 650R with a Roe Supercharger and my car is pretty fast. Before I installed the Roe SC I dynoed my car and got a best 536RWHP/555 RWTQ. I then took my heads off and sent them to my good friend Bill Thompson([******] old head porter) and had him fix a broken valve guide, dome the heads, give it a valve job, and hog-dog the ports bigger for better flow. Anyway, I do not know what my numbers were after that but I would say they probably stayed the same because I lost compression(less power) from doming the heads but I gained power because he took out more metal in the ports.
After SC install, 714RWHP/730RWTQ @8lbs of boost.
Anyway, the original question was
Does anyone have a Supercharged Venom650R? If so, what considerations are there for doing this, as different from a "stock" Viper.
I also have NOS w/200 shot -- should I look into bigger gears? What about the tranny - will it hold up? What upgrades should I consider to accomodate a SC?

PS: Anyone in Phoenix have a Roe SC? How is it working with the HEAT?
Decrease compression, use a smaller shot of NOS, get stock gears, extreme heavy duty half shafts, new fuel system, possibly a new cam depending on the spec's of your cam, and consider buying a 55 gallon drum of Toulene for gas octane booster. The petrol idea was from another thread and I have to say I love it! It cost me $2.9 per gallon and I mix about 15% of it with regular fuel and away you go! It is not something you have to do but I aways want the most out of my car and it is simple to and 3-4 gallons per fill up.
A far as the heat is concerned, what a difference 10 degrees makes and 30-40 degrees is incredible. I would say 40-50 HP from the morning temp of 65-70 degrees to the afternoon temp of 95-105 degrees.
I am wanting to go to vegas when the weather cools down and see if I can put down any better numbers there because of the decrease in altitude (4500-2500ft) but I know eventually I will be going to Cali for my big numbers. That will happen when I am running 12lbs of boost with the after cooler and a new fuel system. I hoping by the end of the year but we will have to see when the after cooler actually comes out.
If you do all the things I have done and will do then add 100 shot of NOS and you should be around 900RWHP/1000RWTQ. 8lbs 714 + 85 more from 4 extra lbs of boost and after cooler=800RWHP+100 shot of NOS=900RWHP and at least 1000RWTQ. With that much power you better look at upgrading the bottom end. I do not know if it will take that much power even in small bursts. Without the bottom end work and installing most of it yourself look at ~$12000 for everything.
