VINTAGE AIR SANDEN COMPRESSOR BRACKET EARLY DESIGN.
SANDEN AIR CONDITIONING COMPRESSOR WITH SERPENTINE BELT.
Anyone following this thread knows I am using a Sanden AC Compressor with jimmo’s serpentine belt conversion. The following is my findings and recommendations.
1. There are two Vintage Air, Sanden to Pontiac Engine brackets. An early version linked at page 2 post #38 and a later version linked at page 11 post 204.
Either bracket can be used in the serpentine belt modification. This first post will be directed to using the early bracket. The early bracket bolts to the head, using the two cast in bolt bosses on the side of the head, and one long bolt with spacer on the front of the head.

Purchase a length of steel flat bar stock 1 ¼ inch wide ¼ inch thick. This modification requires a 9 inch length.
Here in the Seattle area, I purchased this at Tacoma Screw Products, in a 3 ft. length which is the shortest length they have.
McMaster Carr or Granger supply or any industrial supply might also have this bar stock.

This is a CAD drawing of the spacer to move the early Vintage Air bracket forward 1.625 inches.
Fabricate this spacer the Sanden compressor will be in correct alignment with the serpentine belt.
This spacer requires two ¼ inch spacers, one each between the spacer and head bolt boss.
These ¼” spacer can be fabricated from the bar stock purchased to fabricate the bracket spacer or purchased from.

All spacers used in this modification can be purchased here as well.
When taking any measurement insure the measurement is taken from the flat machined surface of the head.
I purchased a 1ft length of the perforated angle to use in prototyping the spacer. To allow inserting the bolts, the holes and slots had to be enlarged slightly with a rat tail file.

Number 1Hole is the Forward bolt boss on the side of the head; Hole 2 is the back bolt boss on side of head.
Hole 3 is the forward bolt hole on the Sanden compressor bracket. Hole 4 is the back end hole on the Sanden compressor bracket. Hole 5 is an extra bolt hole drilled in both the Spacer bar and the Sanden compressor bracket. Drill this hole 2” forward of the existing forward bolt hole in the Sanden compressor bracket.
After the compressor bracket is fabricated a 1” and a 5/8” spacer will need to be added to the front bolt.
When installing longer bolts. Purchase bolts with enough length to provide a minim of ½” up to ¾” threads into the head.

Installing the 93 – 97 Camaro 5.7ltr engine Serpentine belt Tensioner Dayco #89232 or Gates 38145
On page 8 post #154, Jimmo shows a solid link for tensioner-made from 1” bar stock. That bolted to the belt tensioner and the R4 compressor bracket spacer. Doing some research I found that March Performance lists a large selection of turn buckles.
March Performance lists the turn buckle in various lengths from 3 5/8” to 18”.

This is my idea of connecting the serpentine tensioner. Of course I need a longer turn buckle, but this gives you the idea. I don’t think using the existing bolt will work as the angle is too steep and the turn buckle wanted to interfere with the belt tensioner. The distance from the belt tensioner to the compressor bracket is about 7 ¾”. So a turn buckle of the correct length would need to be purchased and trial fitted to determine the correct position for the bolt.
I purchased a Goodyear Gatorback serpentine belt to check the pulley alignment.
