Tri-Power Set Ups

Anyone using the new repro/updated Tri-Power set up from Carls in Ohio. It seems like the perfect deal -350cfm for street- and then over 900 CFM at WOT. This may be my first big upgrade after the dust settles and I actually get to drive my truck again.

Tri-Power Set Ups

I can't remebr for sure how this works. But a 900 cfm 2v set up will not flow as well as a 600 cfm 4v.

2 Barrel carbs are rated at a lower vaccum setting than 4 barrel carbs. I also though like many others that 900 cfm was 900 cfm. It aint. I think 2v's are flowed at 30 in/Hg, and 4v's at 60 in/Hg. It may be the other way around or it could be 15 and 30. I can't remebr for sure. But, the point is a 600cfm 4v will out flow a 900cfm 2v any day of the week.

Too early for me to think about it but I believe 2V's are flow rated at WOT at 3 in.Hg. while 4V's at 1.5 in.Hg.

i don't know how they flow em either, but i know a guy that had a 406, with the factory tripower, in a boat. at wot, the mech pump, with an additional electric could not keep up with it. had to go to 1/2" primary fuel line, the 1/4" just couldn't flow enough. that boat ripped.

I don't want to sound like I am trying to keep everyone away from tri-powers. I think they look SWEET. Nothing looks better on top of a FE than a tri-power. But, I wanted to let everyone know that not all carbs are created (flowed) equal. Pun intended.

That's one of the challenges with the Ford tripower, dialing out the bog. Reason is the secondaries are pure mechanical. Get a copy of the '61-'63 Galaxie service manual, it tells you how to adjust it and it's not that intuitive. Ford played around with vacuum diaphragms on the end carbs. but the chambers were too small. The tripower works great once you get it dialed in, they seem to work better on sticks than automatics though.
