question about Boost bypass...Does it work for one of these ?
I have a buddy who recently bought an new S281 Salleen and had a stage 4 supercharger from the extreme installed a week later..I know this isn't L related but hey it's still a ford..Well over the weekend me and some more buddies were looking under his hood and noticed he had some type of plugin near the blower similar to ours on our truck...They were debating trying to pull it off to see if it would bypass boost. He just wanted to see if he could gain an advantage like the Ls .For some reason this didn't make sense to me b/c I figured this setup is slightly different although its a roots design..I told them not to do it and just question the techs who installed it first..Also if something were to happen, it could void his warranty on the blower.. I'm really curious whether dumping boost is even an issue with his type of blower? I just want to know so I can stop him from making a big mistake..
Also, He has the blower set at 4lbs, and he's wanting to turn it up after it breaks in...Would it be safe for him to stay at 4lbs being his motor doesn't have the same forged internals as the Salleen Extreeme? He's a good buddy and I dont want him going out making a big mistake on this nice machine...Can anyone provide me some info?

The boost bypass is only to help save the transmission between shifts, as far as I know.....so with a manual I'm sure it isn't necessary. I'm wondering now what that might be.....someone correct me if I'm wrong.

Boost bypass is the butterfly which allows the pressurized air in the space between the plenum and the supercharger to be recirculated back to the supercharger intake. This prevents the engine from making boost. The boost bypass is designed to improve reliability, economy, and driveability by keeping the supercharger out of the loop when it's not needed. You press the gas pedal, the engine goes out of vacuum, and then the boost bypass closes. At this point, the supercharger makes boost. An animation of that process can be found at http://www.timskelton.com/lightning/...ost_bypass.htm
Boost dump is when the engine management system senses an abnormal condition and tells the boost bypass valve to stay open no matter what. That is a totally different animal and has nothing to do with shifting. Do a search for "boost dump."
The torque reduction system is what saves the tranny on shifts. Read more about it at http://www.timskelton.com/lightning/..._reduction.htm

Thanks Tim, I was thinking about the bypass and talkin about the dump. Argh! Sorry
