8-71 hh vs 14-71 tripple striped

I am rebuilding my 500 cu bbc that on alcohol and the gut doing my machine work says the 8-71 blower would be better than my 14-71. Just trying others opinion be fore I might make a change . So what would you recommend. I only run 100 yards in sand. sure look forward to hearing some advise still kinda new on blown alcohol

 

need more info. hihelx? retro? large or small openings? 60 or 120deg. rotors.Dave

 

the 14-71 has 2 white strips and 1 black strip with large top and bottom opening standard everything else. The intake I have now for this blower is just a street manifold and I had to make a plats to block some of the bottom of blower to fit manifold.

the 8-71 hi helix with 60 degree rotors and has single white strip on top of rotor. It also has standard top for birdcatcher and normal bottom. One thing I forgot to mention is the 8-71 has taller intake with it. I dont own this one yet but wanting to know if I should get it from friend.

New at this and trying to find out what would be better for me. Thankyou all for helping me out.

 

being a helix I beleave it should have 120 rotors. also there is alot of good blowers out there at a good price try to find a blower that at the hit makes the boost as in a 14-71 hi helix retro small discharge bottom...Dave

 

I would like to thankyou for this info it helps me out on my decision.
Thankyou
David

 

there is a guy on here that has a very nice 14-71 for sale I was looking for one a few months ago and he sent me some pics it looked very nice if you look back on my post you will find it he went by some letters and machine in his name I will also try to find it for you..Dave

this is a very nice blower at a great price..Dave
p.s. stay away from a 60 deg blower they are a fuel blower

 

David, I would recommend a Miersh manifold and 14/71 hi helix. You may have to go to front drive dist. If you have any questions give me a call. Joe 559-287-0952

 

Educate me.

I don't know much about competition blowers, why are fuel blowers undesirable?
