Looking at a blower i can get at good price. Thinking about having a second setup for nostalgia type event and shows. Its 6-71 so as to work with rules.

While my basica engine combo can handle about what ever i can throw at it with this blower.Heck use be same parts in fuel cars when they where piddley 7500 or 8000 hp. Wondering what kind of power a 6-71 with moderate overdrive say 25 to 35% would make.This is on 496 ci Tfx-92 with bae heads, 12.5:1 compression and mag 12.

Would require cpl upgrades to trans. Also wondering about the motor at 49" out,setup for injected motor.Only thing have to buy to make blown would be blower everything else is sitting here on shelf or hanging on wall including 4 new belts.

Any idea on power with this lower drive.Use to 50 to 60% od.If 35% too much for mild setup?

Paul New:
are you thinking of running A/fuel? if so that has a fuel pump rule which limits your OD/Compression combo.

Not really setting up for it right now. But will check those I knew pump and od had limit not compression.Nostalgia thing would be more show stuff or show/race.If there was more nostalgia stuff close I would worry more about rule deal and can always make change if need.

only thing I found in rule book was 70% od max,550 ci max 1875 minimum and 7.6 gpm pump. No mention on compression. So my 526 with 50 to 60% will work if pump can keep it fed.Not sure it would at that od. Ok still just dreaming but its possible dream.
