Mine is stuck in Louisiana and will be going on as soon as I get it. I still don't know if it will clear my vet water pump since I had to go to it, when I got my Aster bracket. I will have my 3.90 pulley and probably overspinning my F1a by 8600 rpms. We will see what happens. I was only getting about 13#'s with the 7.65 crank pulley.

You have a problem somewhere, either a problem with the (highly unlikely) blower, inlet restriction, valvetrain problem, boost leak or a faulty bypass valve. I would not overspin the blower by 8600 rpm, that will almost surely end up in a disaster happening. What have you done so far troubleshooting wise? Bob

Andy, back in the day I was seeing 18 to 20 psi of boost with my 408 with an F-1A and a 3.90 blower pulley at 6800 rpm. This was with the standard ProCharger J Bracket, we had to tighten the snot out of the belt on every run.

Hey bob I did do a boost leak test via the brake booster hose. I sealed the tubbing right where it connects to the head unit. I found out I had leaks at my injectors and bought the katech thicker o-rings to seal that up. Also had a leak above the throttle body and i sealed that. A guy I know said he overspins his vortech by 10% and no issues. So you think spinning it passed its max will damage it?

Andy, you could try making one or two runs in a dry clean area without the inlet and filter and see if the increase in boost doesn't shock you. Bob

i know KP drilled holes in his inlet hat and put smaller filters along the body off it to add flow into the blower. its an idea. I always look to him for ideas when it comes to making things efficient. the guy had a nasty setup and didnt even have the bells and whistles some of us have.

That smaller hat will only flow about 13#. Take it off to see true boost potential.

Procharger supplied filter on the left new filer on the right. http://mycarpics.shutterfly.com/276
K/N # for big filter ^^^ http://www.knfilters.com/search/prod...id=449860&rw=1
Added this little filter for the bypass hole. I had a frost plug in that hole to start. http://mycarpics.shutterfly.com/277
K/N # for the small filter ^^^ http://www.knfilters.com/search/prod...id=449856&rw=1
