i started the install on my sn-89 i won off ebay well i mounted it and run the belt and started the car with the piping off and at idle you could feel the air coming out of the charger and as soon as you rev the engine it stops pushing air and the impeller stops and the belts not slipping whats the problem?? please help im very confused
Internal slipping or belt slip.
but what is slipping inside? i can hold the impeller with my hand and spin the pulley what do i need to do?
The blower unit compressor is spun by ball bearings.If there not preloaded correctly or there damaged they won't spin the compressor.
Take the belt off and turn the pulley it should be hard to turn.

yea the pulley spins freely and very smooth and the impeller turns but if i hold the impeller than the pulley will still turn just harder to turn
Sounds like the unit just needs to be gone over.OR maybe a thicker bellvue washer.Give paradise wheels a call tomorrow
Not enough tension on the ball drive. Check the case bolts first and make sure they are tight because they also apply pressure to the ball drive. If the bolts are tight then it needs additional washer(s) installed under the ball race to increase the ball pressure.
are these special washers? how hard is it to do ?
also how much pressure?
The pulley bolt needs between 28 and 35 inch/pound of torque to get it to turn.
Torque the casing bolts first to be sure, bud don't be an ape in torque them bolts becouse the housing is aluminum.
Number 19 is the bellevue shim(s) and needs to be added more if more ballpressure is needed:

how do you know when u have enough ball pressure?
By putting a torque wrench on the pulleybolt and see how much torque it takes to turn the pulley.Quote:

ok i took it all apart and tryed some diffrent shims and put it back together and it seems ok if i hold the impeller i cant spin the pulley, with out any hoses connected to the charger and starting the car what kind of noise should i hear? also how smooth should the pulley turn?
Let us know how it goes
Pulley should be smooth but it takes a good wrist twist to get the pulley to rotate. Without fluid you should hear what metal against metal sounds like. Just make sure you verify the rotation torque on the pulley before you finish the install.
ok thanks for all the help so far but now i got a couple more problems it sat over night with it full of fluid and i go out in the garage tonight and its wet with trans fluid around the where the front casing bolts up so i removed the charger from the car and carry it over to my workbench and notice there is fluid coming out of the threaded bolt holes that go around the front cover what would cause this? also there was fluid coming out around the front shaft coming out right down the slot for the key was what do i need to do to fix everything ive just listed thanks again for all the help

and another question i have a smog pump delete bracket and am trying to mount my alternator does anyone kno how to go this?
Fangle it. The SN blower bracket, as is, needs the smog pump in place to get the belt wrap to work.
well i took the idler off and put the pump back on and now i cant get the alternator on for the sway bar
You got drop or worn out motor mounts?
F=MA
yea the cars lowered 2" but right now the car is on jack stands with the stands on the k member so....
Read carefully please. Are your MOTOR MOUNTS dropped or old? NOT whether or not your car is lowered.
F=MA
yes the mounts are old but what do you mean by are they dropped?
Some people install drop motor mounts to lower the motor to clear tall intakes and such. Motor mounts, as the get old, drop themselves as they wear out, causing clearance issues. I'm guessing we're talking about a Fox body Mustang here, kind of notorious for collapsing engine mounts, causing exhaust hitting or clearance issues around the steering rack, or accessories coming close to sway bars and such.
