demon 850
i picked up a pretty decent looking and suppisedly good working demon 850 off the fb marketplace. i was actually needing one a carb to use on a couple dif intakes i got. plan is most likely just clean it up and rebuild it but....
its an annular booster style carb now, anyone converted one of these from draw through to blow through? what all would need done? i see theres a company sells an e85 conversion for it but not too much on blow through info. |

At one time they had one that had removeable boosters you couple swap in -different size downlegs or annular! As well as interchangable sleeves for different cfm! I had Jeff convert a regular 850 into one of those when the parts were still available from Demon.
I have an 850 down leg Demon on my IA motor.

Getting that set up for blow thru boost besides the swapping out of the boosters I would leave to a carb shop to undertake
