From Dyers website : Dyers superchargers
9. There are lots of superchargers off of diesel engines on ebay and other auction sites. Are any of these good to buy?
There are many different styles of blowers that came off the diesel engines. The only cores of any use are the 71 series blowers. There are 4-71, 6-71, 6v-71, and 8v-71 Cores. These 4 blowers are different is size and shape. The blower that has the most parts available is the 6-71. This blower has 4 hold downs on EACH side of the case (8 total) on the very bottom. The v series blowers have angle hold downs on each side (4 total angles on the 6v71, 6 total angles on the 8v71). Unfortunately, no intakes or carb adapters are made for these v series blowers.
