Edelbrock’s New Carb Is The Most High-Tech

-
Looks nice bud.

And thats exactly what I thought you would say.

Why? You got your holley guys and you got your eddy/thermo guys.

Its an interesting cross over thats for sure.

My bet is it has to do with expiring patents or some such bs.
 
Ha, this thread is the same as the car shows. The people keeping the carb business alive are people that don't trust or understand fuel injection. Carburetors have been around for 100 years and at this point, we've probably learned all we're ever going to learn about them. No matter that there hasn't been a carb on a new car in 40 years...

I know I said earlier that it was kinda cool and all but when you really think abut it, for Edelbrock to put so much time and effort into developing this carb it seems kind of silly and not very forward thinking. I really believe it's because they got left behind in the EFI race.

More adjustbaility is fine for the small segment of the market that wants their tune to be razor sharp but if that's what people want then why stick with a carb? And even for the majority of the guys that "just want to get in their car and go" what's the point of having all this adjustability? I can't see drag racers giving up a two circuit Dominator for one of these.

Every carb I've ever had ran different on different days, that's just science. Carbs are at the mercy of the ambient air no matter what gadgetry you attach to it. Why do guys have weather stations at the track? Atmosphere changes rapidly and the mixer has to adjust or it won't perform as expected.

Conversely, even though it seems like it's being marketed as such, EFI is NOT a magic bullet. There are instances where a carburetor will outperform EFI but it's a small margin and as time goes on and smart racers spend more time learning about it the gap closes. Many of the really fast cars at the drags these days are injected and tuned with a laptop.

Agree with Joe that most of the time these things fail because of user error. There is a thread on the other "forBodiesOnly" site now where a guy is having problems with his Sniper. It started blowing black smoke and running rough. He keeps replacing 02 sensors and Orange box ignition modules as if those are what are causing the problem. I'm not even sure how he gets the the thing to run with an orange box but it's not worth the time to delve into that.

Regardless, 02 sensors generally never fail but this guy had one take a dump within a few miles? Then he goes on to say XYZ data number is way off and ABC sensor number is pegged and does not understand why his timing is locked out in the software. But you know the 02 is bad?

Obviously the problem is beyond a bad 02 and I said so but all the other replies in the thread are agreeing the 02 is culprit. So he takes the 02 out, drives the car around the block and comes back to the thread posting it ran fine so it has to be the 02. :BangHead: You can only help so much. I would not want to be a Holley tech line employee!

Carbs are fun, I still mess with them but lately it's been on other people's stuff that I help with. I'll never get rid of my carb stuff completely, I have way too much time and money invested in them to abandon it forever. I probably wouldn't buy this Edelbrock carb though.

Tuning EFI really is a similar process, it's just a different method of viewing the information. Some people just won't trust computers and electronics and will never see the benefits of EFI even though it could be a good thing.


I understand EFI. I trust it too. Your blanket statement is silly. I don’t use it because in most N/A applications a carb will out horsepower EFI. And a carb can and will idle like EFI. An, if the carb is tuned even close it will self adjust for most weather. Warren Johnson, who can tune a carb said he didn’t change a jet going from Denver to Sonoma. I couldn’t care less about blowers and hair dryers. If I was doing that, and the power was going to be above say, 800 hp I would use EFI. But I’m bored by power adders. So it’s not what you think at all.
 
@j par

And my god man. If your car came in to check air pressure in the right rear id replace that hard line out of the master....

Insert piccard face palm pic here.


:)

Ha!

I do love your car.

If you ask me it's a great design, it's basically a hybrid with 4500 height & 4150 versatility.
This carb is as tunable as a carb can get.
Plus they did something I thought is a good idea by peening the surface so the air is constantly sheared off of the surface. With the longer venturies it's a guaranteed gain in torque. Downleg annular boosters, if it's affordable to me I'll try a 950 cfm

Actually that's an old picture I don't have those valve covers or air cleaners on there anymore. I actually took that hard line off that goes down to the line lock which I took off...
 
I still like it but hell, what do I know? Im driving around in a 1963 Nova. Just kidding....




Its broken down.

****.
:D
 
What it is is a 4 circuit carb when you only need 2 circuits. One day I’ll get my hands on one and pin it, but there isn’t a need for a 3rd circuit on a Dominator so why Edelbrock thinks you need that and a 4th circuit on a 4150 I can’t say. It looks like they went cheap and used 12 hole boosters. That’s only marginally better than the 8 hole boosters Holley used.
The intermediate bleeds are split If I remember correctly

I'm in the market for a mechanical secondary to try on Vixen. I have one, but the 650 version of this looks good.....but the price point is gonna be the hangup. This AIN'T gonna be a 400 dollar carburetor.

Yeah I bet not $400, I have a couple carbs to build first both will get me to my goal
 
Yeah, I do agree, really no reason for it.


I suppose if the 3rd circuit is blocked off out of the box it’s not a bad deal. But everything I’ve seen shows a functioning 3rd circuit. It will be so rich it will never clean up in the middle.

Unless they figured something out by splitting the intermediate bleeds, I just can't put it together in my head how, except there's more air to immulsify the fuel which may make that circuit easier to atomize . I'm probably thinking about it wrong though & please correct me if I'm wrong

I believe the test engine is a 555 musi so maybe the 3rd circuit wasn't loading it up

Well that’s exactly it. The more you add emulsion the richer it gets and the sooner it gets richer. There are times when I run one emulsion hole. And that’s it. And many times I use one .028 hole at the top and a .022 hole near the bottom to get the upper rpm part of the fuel curve right.
 
lol.. follow the efi threads on all the mopar forums and look how many oldheads are still scared to death of efi. carbs are not dead by a long shot.
Plus, and I am ready for the FI lovers to pile on, I have heard WAY too many stories of problems with all of the EFI units. Granted that a lot of people have had great luck with them, and swear by them, I have just seen too many complaints. Although a smooth running EFI setup on my car would be nice, to do it right costs $1800-$2000 or more, and my car runs great with a $450 Eddy carb. I am not "scared to death" of EFI, I just don't like all the bad press I have read.

It's too many stories for just us "oldheads" and operator error. There has to be some truth to some of the issues being the fault of some of the systems. There are defective products in every walk of life.

My opinion is, that's a hell of a lot of money (for me anyway) to lay out for something that may or may not work out. Although carburetors have gone up in price, they're still not as expensive as EFI, especially considering you need an entirely different type of fuel system which adds even more cost.
 
How did a hung float burn his car down ? It should have just killed the engine .
This is a sincere question not sarcasm.

End of the track at the shutdown. We only found the hung float. The fire was probably somewhat manageable however it's a track that was never know for above safety implementation in place. When the hood got pulled off it was game on then.

My point is either system can give you this result. If hardcore guys snarl at the sight of a Laptop sitting in a passenger Seat wait until the EV start showing up and it's right around the corner lol......
