Alain ... I forgot to mention that I loved your web site. Good to see 16 valves in race trim. I am just in the "Performance driving" stage and may or may not move on.

On my problem, the throttle does not "freeze" at full throttle, only between 20%-75% or so open. It is not a cable or spring problem because I can recreate the symptom in the garage by disconnecting the by-pass valve and I cannot move the throttle by hand. My only real thought is that the shaft is warn and the butterfly is binding against the side of the throttle body. It looks like time to buy a new throttle body but I would like some confirmation that the $2-300 part would solve the symptom.

I also have a "blower creep" situation that I need to solve. At an intermediate throttle, the blower compresses more air than the engine needs and the pressure builds until I disconnect the blower. I have a vacuum actuated by-pass that works fine with vacuum but does not limit boost. I am beginning to look for an adjustable blow-off valve with a 1-200 CFM capacity. Do you have nay suggestions on products or sources?

Again, thanks for you comments.
