PROJECT OXYMORON ( HO CFI ) ????

I bet you get a boner over the venturi carb.

Actually every carb is a venturi carb. Venturi is the air passage, 4 barrel = 4 venturi. What you meen, I think, is the Variable Venturi carb. I think there cool. I had one on my parts car and it made great power, and it worked great even after sitting around for over a year without me ever running it.

Oh, I meant variable venturi. It was a 82 lincoln cuntinental. I miss it, but my dad was always working on my carb, It would never kick down. Which was kind of cool, but sometimes it wouldn't want to start & with the choke was closed.

Marquisman knows what I'm talking about.

UPDATE!!

I plugged in the HO computer to see what it did. well, it started and ran, but i had to keep my foot on the gas to keep it running. And the whole time, the air fuel meter read WAY LEAN the whole time, even when I revved the engine. I aslo tried putting it in gear and gasing it a little , same thing. I could barely to move off of the lean side.

I didnt drive it becuase I didnt want to risk and damage... its not good to run lean. This behaviour supports my theory that the computer is seeing way too much vacuum, and thinks it is always closed-throttle cruising (when the vacuum is higher than at idle, and when the computer leans out the fuel mix). This is becuase the HO cam produces less vacuum than ours...

So it look like I need a cam! or some way to fool the map sensor. hmmmm

wonder if u could convert the cfi to mass air?

[gadget73]

That would be interesting. Doubt there exists an ECM for that tho.

[mrltd]

You should get a 4 bbl intake and get the 2bbl adapter.

STANDALONE!!

update?

[85crownHPP]

no update.
This project is on hold untill I have the resources and money to do a cam swap (this includes another vehicle in case it goes horribly wrong). Im not about to experement on my daily driver.
This is just a sticky incase any visitors or new members have info to add

[85MercPark]

So, any progress? What is the HP/Torque difference of a stock CFI vs a HO CFI?

[83tc]

i like the 4bbl intake w/2bbl adapter idea, im leanin more towards a carb swap soon, tryin to ebay parts but its hard to find good shit cheap....

[Grand Marquis GT]

Don't waste your time with a 2bbl.

You will NOT be happy.

[88MercWagon]

Standard CFI
130BHP@????
???ft/lb@????

HO CFI-
165 BHP@3800rpm
254 ft/lbs@2000rpm

[85MercPark]

Not too bad of a jump, but not worth the money I would guess
