efi vs carb

[94svtcobra]

I know Ive been asking about different efi setups for my car, but was wondering how carb setups match up to efi setups? one benefit I was thinking about is that carb setups, are a lil more simple to work on, but didnt know if I could reach my hp goals with a stroker carb setup.

thanks, Mike

stay away from carb!!!!

well thats my opinion, my buddy did that and he regrets everyday that he did

[94svtcobra]

any reason??

old school tech, race car only

he realized there was alot more ways to mod an efi and different routes that made can make the car faster and keep very good drivablilty.

He went from 18mpg to 8mpg.. Lost driveability of it. And when i saw drivability i dont mean to the store i mean from pittsburgh to mt pleasant or so on and so forth.

if you want a high horsepower race car go carb

if you want the best of both worlds go efi..

this is in my opinion

and if you wanna drop 3500$ on a bunch of overpriced electrical crap then go EFI, LOL, intake+carb=700$=DONE

[94svtcobra]

what kind of numbers could i get out of a carbed stroked 331 with maybe a blower or carbed na 347

[CESCO]

my na 347 is at 300hp at the wheels with efi.. i am having issues on getting it tunned properly.. i started to do my own research and am going to try a couple of things to hopefully clear it up..

AMEN!! EFI Tune 4-600 plus the 3-4 hr drive each time ya need a tune. Carb tune by someone close or yourself so very little. As far as mileage is concerned its only a four barrel when your foot is to the floor. My non nitrous running 351 even with the 750 dbl pumper on it wasnt bad at all. I ran it several times last week to a car show horsed around and around home a lil went to the gas station and put 21 bucks of 93 in it. 3.85 a gallon I'd say it didnt use to much. A properly tuned carb is just as responsive as efi. I'll be running a vic jr intake(carb) 250$ My carb is a lil pricey but it is almost adjustable to anything I could ever want to d0. So it maybe 600. A holley upper and lower is 600 alone. Add in a tb and elbow adapter for a 94-95 car and how much more did ya spend? Not to mention 94-95 ecm's kinda are a pain. I'd say go carb but, I have been accused of being old school. Oh if ya want someplace to ask tech go to the link in my sig. He has an online tech support where you can personaly ask him questions. Woody will give you an idea either way.

Its all in what you wanna do, and usually what you wanna do it greatly affected by how much you wanna spend, carb is deff cheaper, but you will lose in the mpg area..

my setup was ~ $600. weiand Xcelerator + Demon I can sit around tuning all afternoon for free (almost). jet changes are quick and easy and cheap but after you find the right setup for your engine you really dont need to mess with it. if its not responsive enough for you, put in the yellow spring :D

but you will lose in the mpg area..

but... we drive mustangs. if i was that worried about mpg, i'd be drivin' a toyota

#1 Its way cheaper.

#2 Its alot lighter overall.

#3 Diagnosing a running problem is cut down to a very short list.

#4 Every NASCAR class runs 'em.

#5 MPG is the last worry on the list if you're building a fast car.

I don't want to think how much money it would have cost me to upgrade from a stock '87 running gear to support a 414 ci. $200 intake, $400 carb. Done. Compare that to injectors, intake, throttle body, mass air, upgraded computer. Ugh. With a carb you eliminate a shitload of possible failures. Not alot of younger people go with them, because its a huge scary unknown, same reason the old fogeys go with carbs.

Id go Carb.....alot cheaper.. EFI = pita Carb with a nice nitrous plate system

[94svtcobra]

if I went with a carbed setup and wanted to sc it, do the roots style blower have to have a scoop out of the hood or can it just have the air filter on top???? do they make centrifugal style for carbed?

They do make cent. for carbed and depending on the size of the roots it may or may not need a scoop. With a nice sized cowl you could probaly get away with a single carbed blower.

The Cent kit is for a lil older car but a good shop might be able to make it fit correctly(or may not need anything)

if I went with a multi carb with spray, would I need multipul nitrous plates???

You know about that hood scoop issue you were worrying about? That would be the tunnel ram lol. You could make 500ish.

wait I'm not following what your saying
