i see the pic of the 2valve,its not that i didnt believe it couldnt be done,bc i have seen it before.the hp numbers just dont sound realistic to me.i think its a cool idea without a doubt,but would never think to take a fine running fuel injected 4.6 and carb it,just doesnt make sense to me unless it was in some sort of like project car or something a 4.6 wasnt originally offered in.

Well if I ever have a spare DOHC laying around, and a Fox Body to put it in, now I know not to bother with fuel injection.
That article was impressive.
But i'll stick with fuel injection.

It amazes me how many people just assume that because EFI is the newest technology that it must be the best all around. It's more reliable, has better driveability and better for fuel economy over a carb but when it comes to NA HP a carb is hard to beat.

I can't believe all you guys are buying into the horsepower claims made by Hot Rod magazine. I mean....I've got some swamp land in Florida I can sell you at a great price if that's the case?

you said it right there,i like my RELIABILITY,DRIVEABILITY AND FUEL ECONOMY and carb doesnt make more power in my opinion,ppl think it does because its a lot easier to swap a carb on and tune it then taking your efi car to a certified tuner who knows what he is doing.

It's swamp land in Arizona...
Florida has quite a bit of swamp in it.

A carbed setup will be able to flow better and make more power...with the same setup I would say that a fuel injected car would make about 350 flywheel hp vs the 400 carbed setup
You would lose reliability,fuel econemy, blah blah, all that stuff..
Basically, there would be no point in switching to a carb setup unless you had a race car.

the article wasnt to convince anyone about numbers, it was to see how a carb setup changes the power curb and such. Obviously nothing is for sure, because were talking about 2v's here, thus my comment.
thats ok if yall dont believe their claims lol that wasn't the point. just compare dyno sheets though, and see the difference in curves lol
you guys sure are a hard crowd to please

In your opinion but anyone that has raced and used both or done swaps from EFI to carb knows otherwise. In a NA application a carb will make more power and can be every bit as good as EFI. The downside is if you drive in different elevations or in areas with major weather fluctuations. However as an example on my 92 LX I got better MPG with a carb and had no issues driving it back and forth to work every day for 2 years (70 mile round trip commute). This all the while picking up 3 MPH over my previous EFI set up.
Also for those doubting the Hot Rod Mag numbers you have to keep in mind that is on an engine dyno (flywheel power) with no real accessory drag. Their numbers are right in line with what most cars with similar mods make today. The difference being power range. For a 2V modular it's really not going to provide any advantage to the daily driver street crowd it's more for racers and guys wanting to drop it into a classic and not wanting to deal with all the wiring and sensors of a stock engine.

i have done a swap and only because my efi was so messed up it just mad more sense to go carb at that point.i would never do it again if i didnt have to though.
the only reasons a carb setup will ever beat a FI setup in anything is because of poor tuning or restrictive stock parts ( manifold/TB/injectors) trying to flow more than they were intended to.
a properly tuned efi setup with a free flowing intake will out perform a carb setup. If needed I can list the reasons, there is a lot of them..
BUT there also is some very good things a carb setup has going for it.. for one it's simple for the EEC challenged to tune, sure you need some skill but you don't need as much equipment.
another thing is going carb removes all of the stock restrictive efi stuff ( intake, TB and such, stock tuning) that was fuel economy/ emissions compromised and replaces it with parts thats main goal was making HP and emissions was not a concern.
A EFI setup with a very good flowing aftermarket intake, TB, MAF, filter and tubing designed without emissions or fuel economy in mind with a tune that is not emissions/ fuel economy compromised will produce more power..
Sure it's cheaper to build a max power N/A motor carbed but I rather spend extra money and build it EFI

Well that is all well and good but the bottom line is the carb intakes flow better than our stock intakes. Plus most of the EFI aftermarket intakes for the 2v arent all that great. I cuold give a **** less about fuel economy. I want power, ease of tuning and a carb setup really cleans up the engine bay! I bet going to the carb setup would net me another 10rwhp or more and I could easily tune it for the conditions on the fly.

Most intake swaps wont give much more than 10rwhp or so. The major benefit is the tuning abilities.

I never said it was a good option for most people on this site just that carbs get a bad rep from people because they think of their parents rust bucket that has starting troubles, backfired or generally ran like crap back in the day.
I wouldn't even dream of swapping to a carb on my Mach 1 because it's my daily driver and the power difference could be made up with a smaller pulley (blower) or a power pipe. Going to a carb set up would be a better option for me if I was in a situation where I had a race car or a limited use car I wanted to make as easy as possible to tune without having to deal with stupid things like a sensor going bad or needing to break out a laptop to correct a driveability issue. Specially in a NA or nitrous application. A total conversion for the power difference wouldn't be worth it unless you are running in a race class that depends on every single HP. 4 years ago when I had my 2000 I wouldn't have even hesitated to try this set up because 10 HP would be a big difference.
