Carl,
Thanks for posting that chart. Does the stage 0ne kit not come with an intercooler? Also, I noticed the air/fuel ratio numbers below the HP/TQ #'s. Am I way off base or is that ratio going very lean? Would your new fuel management kit take care of this? I notice that you do not offer a stage 2 kit for the 84. Why is that ? Also, how can I tell if I have the L or LH Jettronic fuel injection?

Attached is a screen shot from the data logging I have done with my stage 1 test car. As you can see I have been able to get the recipe pretty well figured out for this kit. I hope this type of documentation will assure interested parties that this kit has been thoroughly tested and sorted out so you don't have to do it. My test car has over 4000 miles on the installation and the system has been totally maintenance free.
The big advantage to running the centrifugal superchargers is that they bring the boost on gradually so you don't have the "tip in" detonation problems caused by too much boost too soon with the stock ignition curves. It has been my experience, and observation, that anything more than 4-5 psi boost (without doing anything else) below 4k rpm will experience detonation with the stock ignition curve.
BTW, this system will also fit the 85-86 cars.
