New sanden 4261 which is a SD7H15 variant at 9.5 CID per revolution with a 4.41" pulley. With the 6" crank pulley it turns 1.36x crank speed and has a maximum speed rating of 8,000 rpm and a maximum continuous rpm rating of 6,000. I have the PCM set to shut it off at 5,200 rpm or WOT.

The March underdrive pulleys when I test fitted the compressor bracket that I had to grind down to clear the taller aluminum valve covers. I painted that bracket with Duplicolor cast-iron to match the alternator bracket.

Swapped the 2006 5.4 Ford fan bladd out for the cut-down LBZ Duramax blade. Its on a severe duty Hayden clutch for a 2007 TBSS.

Left vent after idling for 10 minutes with the puller fan activated with HP Tuners. Still need to program parameters to make it come on as an auxiliary as well as stay on for a few minutes after the engine shuts down. I was reassemling the dash after putting the cluster back in. I replaced burned out bulbs in the cluster with red LEDs that are both brighter than the OEM bulbs and do not mess with your night vision as you scan the gauges.

This is the center vent, 10 minutes after shutting off the 16" puller fan. Still colder than the R134a stock system ever though about being. I think it ran about 56°F at idle in this heat when it was NEW!

This is the Sanden SD7H15 performance chart. At my ~2,100 rpm cruising speed with the 1.36:1 overdrive will be turning ~2,850 rpm and delivering more than 2x the BTU output. Going off memory, I think the lowest I have been able to adjust the cycling switch before the evaporator freezes is around 29°F out the vents. At 38°F at idle, have no doubt it will be in the low 30s going down the road.
