The jack shaft has a few advantages. None of them major outside of more blower RPM. The front drive has the ability to spin beyond eatons max blower RPM anyway. Heat can become a real problem as you spin them too fast. As you introduce more cubic inches the added RPM the jack shaft enables can create a lot more power capability in short bursts.
Basically the advantages are as follows:
The first is you can OD the rear and run a larger pulley up front to basically completely eliminate belt slip. The second is in theory the front inlet is a more efficient design than being angled like the front drive blowers are. It can have an easier time getting the air it needs to compress.
On the negative side Id be willing to bet that the added parts on the jack shaft actually create slightly more parasitic loss. Especially when dealing with cog pullies.

some more progress today. I removed all the wiring for the gauges on the passenger side of the engine bay. Man that took forever.... I got the blower all torqued down. then i decided to work on the Heat Exchanger plumbing...
Hoses all mocked up, i still need to secure them...
Heat exchanger mounted, i had to move the Tru-Cool over a little bit to use the mounting brackets that came with the kit.
Then i applied the nylon hose cover. I also used heat shrink on the ends. This nylon stuff FRAYS soooo easily. If anyone trys this, make sure your burn the ends before sliding it over the hose. Then after you cut it, burn it again.
all the rest of them

Such a disappointment...
