any advantage? and worth the hassle?

[benno440]

is there any advantage to carbies over a fuel injection system, just trying to figure out whether i should sell my new intake carbs etc. and buy one of those EFI systems.

no wiring harness to go bad

Carbs are cheaper, but EFI self-tunes which helps if you don't know how to tune carbs. EFI has easier cold starts.

I'll add that from what I've read, well tuned carbs may get you more horses. I would go EFI if good gas mileage and street manners were high priority, carbs if I wanted to race or at least get whiplash when you hit the GO pedal.

I still think that carburetors will make more ultimate power. Also, if the carbureted fuel system is set up properly, you can come fairly close to EFI driveability. Using the correct return line and the like. You'd be very surprised the difference you can make.

 

[benno440]

yeh well have been readin into it and they reckon with the efi you do lose top end power, but gain torque and low end, and get easier starts better mileage (who cares about this though) (didnt stroke my 440 and add an extra carb for this hehe) also seems like alot of money, and i will admit i am no pro on carb tuning and i live 1000km away from a dyno

A properly tuned port injection system always wins in my opinion. One important factor with port injection is no fuel distribution problems. Also, an injection system will be much better equipped to deal with the new gas (in the US anyway - not sure what you have). The bad part is the cost. From a survivalist standpoint the carbs are pretty fool proof. But so are point ignitions and mechanical fuel pumps. I would like to break into EFI someday and will probably do it with one of my cheap used Holley Pro Jection systems or the Megasquirt kits.

all depends on the injection sytem you run.all the high end racers run fuel injection unless they are required by class to run carbs.on the lower end(or street use if you prefer)you will get more top end power from carb's then fi.just cant get the fuel air volume out of streetable injectors you can from carbs.

Megasquirt kits.

I once knew a girl with one of those...lol

If it helps, Ferrari back in the day lowered all there expected HP ratings when changing to FI from carb, but after doing so they found that while the peak HP as lower, the car was consistently more powerful as the FI tune was constant.

Having come from an FI performance background, I personally think there is a lot to be gained from a well designed FI setup. But its up to you what you want from the car. I've done the high HP thing, agonizing over each mod. Making sure every thing flowing the best as possible etc etc. So my Coronet will be about a rough noisy torquey Big block machine built for fun, not hero'ing. So its going to be carbs, cos they something new (for me) and period.

With your resto-mod, high tech thing, I'd think a computer controlled FI system would sit nicely.

i concur due to tuning options

With EFI, I see guys in the pits with their lap tops just a tuning away because the weather changed a bit and are always mapping out the tune according to what the weather is doing. I know how to set up a carb to run consistent numbers and not have to fiddle with the car all the time....even if the weather does change a couple of degrees or the humidity goes up a couple of points. I'm out there to have some fun and not spend the whole afternoon tuning on the car only to get knocked out in the 1st round because it ran .05 off the dial. Also, I find it kinda odd that with the factory EFI cars, they never run consistent and can vary a full .10 from round to round. I know that's a factory setup but my factory carbs ran better than that. To me, it's not so much how fast I go but how consistent my car is. I dunno....I like to stick with what I know works and for the least amount of work. After all, we're supposed to have some fun and not work our nuts off all the time, right? Anyways, I have a room full of carbs and nothing when it comes to EFI stuff so I'm not going to spend a chunk of change just to make a change from something I already know how to set up and make it work. Might have something to do with teaching an old dog new tricks?

 

[RustyRatRod]

Well said Crankamousamous. I couldn't agree more.

 

[Moparmatt72]

i personally like carbs better. all you need is to maybe rejet a bit depending on elevation but if you keep track is easy to dial in next time. just use a wide band air/fuel gauge and tune the car accorrdingly course id run on per bank. thats what ill be doing to tune mine. course the only bad thing is race gas clogs up the sensor after a while but a good blast dont the track should help clean it off.

I have to put in my 2 cents... fuel injection is the way to go! sure carbs can work fine and as some said get a little more power at the top end. however, fuel injection is tunable throughout the complete throttle range in just seconds. with out taking the fuel lines off unbolting the carb and linkage, just to guess at what you should try. I just put a throttle body style injection on a '64 and talk about nice. Just turn the key, it starts and then you can go without hesitation! without waiting for the choke to pull off (if you have a choke) or feathering the throttle until the engine is warm. and yes i have run dual carbs, i have run modifies holleys and carters and i still think fuel injection is the better way to go. if you dont think that injection can make enough power you might want to talk to a top fuel dragster team.

I guess it's the old guy in me but I love watchin younguns go out in our lot sometimes to move a carbureted car. They caint do it. They don't know how to keep one running. Funniest thing in the world to me.
