Its spring loaded yes, but your engine at idle produces a lot of vacuum, that should overcome it. but it may need adjustment (it has an adjustment) and its also able to fail (the diaphram if it fails would prob be a vac leak but it wouldnt be able to overcome the spring)
I Do not think you should hook up a toggle , but you should hook up a l67 PCM and controls
Your playing with fire especially if your car has traction control

I am also surprised it runs fine... considering everything

Anyway, the hose clamp thing, constant tension clamps are fine if you have the tool for them. They are superior and they wont bite into the hose, then lose clamping force that way. thats part of why its dangerous when dealing with 50 some psi fuel pressure coming on those lines.. make sure its hose and clamps are rated for the task so you dont lose your baby

I Dont recall how that tensioner assembly looks where the alternator mounts.... you MAY be okay... but realize the third mounting eye was to provide deflection support, if the 2 other ears are taxed its possible to overburden them but they may be robust. the brace you cant use since you have a supercharger in way may also help vibrations or noise but you may be okay...

but on that subject, if you ever need a new alt, I then advise stepping down to a normal CS130D or AD230 unless you go to a different tensioner/bracket which is a lot of work, but it would allow you to use the more updated secure mountings

Heres what I mean

heres just an idea of what it would look like

Do you have the original modulator? I would replace that if so

In my opinion it would just be a lot easier to swap a L67 in than do the top swap stuff unless someone had a good L36 and a parts or blown l67 they could merrily transfer components and wiring and etc.
Especially early 96 when Series II L67 is new kid on the block, changes were coming before you know it that just add complexity etc etc. the OP would be wiser to buy a regal with a supercharger, they were trimmed well Im pretty sure compared to the normal one.

In your previous reply I didn’t know what you meant by the modulator? And I agree it would probably be easier to swap or just buy a car that’* already supercharged but I’ve always wanted to supercharge my car and I wanted to see if I could do it.

Also if I happened to get a L67 PCM would it have to be programmed in any way?

Yes, transmission is different.

Okay thank you

Find 4T65-HD and matching L67 PCM, then you can use HPTuners to fine tune the engine side of the software. This is much easier/safer in the long run than trying to tune a L36T/* on a light duty trans.

Its been discussed with a stock L36 tune, using stock L67 injectors, supercharger and flat top pistons, these engines are cranking out a lot of HP, more than a stock L67. Some have even cautioned bottom end damage because the engine is making more HP than it can handle. This is why the L36T/* has to be scanned, tuned, scanned, tuned. Then beef up rotating parts.

Thank you for all the great information. Im thinking I’ll drive my current transmission into the ground before I upgrade but I’ll definitely apply your advice in the future because it sounds like a great idea.

just be careful with launches, low traction scenarios, and if you want to extend its life, i would put a auxillary trans cooler with a magnetic filter before it or the radiator end tank one(depending if you just bypass it or use it in conjunction, you want to keep metal out of the thing) and a new modulator

The modulator is the vacuum controlled gizmo on the front of the transmissio if standing in front of the radiator looking down in the engine bay. it should have a connection to manifold vacuum.
The reason I say replace is fun things happen if the diaphram breaks

now this is beside the quadrajet on a 1977 small block buick (V8, its what the V6 and 3.8 and 3800s come from lineage wise ) and the transmission is a RWD th350, but the modulator is the same for TH350, TH400, 440-T4(your transmission before it was electronic, 1990 was last year. it was also called 4t60. ) 4t60e, which you have, 1991-1998 or 1999 in some apps I think. Uses a modulator still, despite being electronic controlled (no TV cable on a 4t60e) it controls line pressure (modu)
