Roots blower physical size

>Jack, I went with a 6V-71(large rotors). They pump approx. 10% less, but are 2" shorter(body). "Dyers Blowers" makes a mount-casting, to fit this V6 blower. I suggest you peep their webb-site. It comes down to fit and boost required for your size motor. Good Luck, ateam.:thumbrig:

I am still a long way from actually buying the blower. I am concentrating on the rest of the engine first. But, from what I can figure, I will be trying for an 8 to 10 lb boost limit. I am looking at a 7.5 to 1 static compression ratio. I am also looking at a water/meth injection setup to be on the safe side.
I have seen a couple of 6V-71 setups for sale and they seem to be cheaper than a 6-71 setup. I haven't figured out why yet, but I will.
