Edelbrocks new offroad carb...

[Stuka]

Saw this add in petersens, looks like they (edelbrock) have also come out with an offroad carb.

Has some nice featurs, not sure what it cost yet though.

[youngjeeper]

i saw this at pepboys, i htink it was $369..

I hate to say it but if it has the same outstanding features as the other Edelbrocks that does not mean much. I put off road needle and seats in my Edlebrock and it still did not perform well. The fact that they are also offering and "selling" the fact thaqt it looks good because of the anodized fittings is pretty pathetic. My .02.

[youngjeeper]

pathetic but it will sell smile.gif

The dual fuel fitting are nice, any of us with the 1406 could tell ya why... :D

It's probably the 1406 with the off-road needle and black parts instead of brass. Dang, if it's the same, I'd be interensted just so I didn't have to have fuel lines running over my intake.

Hmmm I had a post in general discussion you boys must have missed. I love mine runs great. Was like day and night over my Avenger. Look for my post.

Its not a performer 1406 with a few mods. Its a very different design. If you have a 1406 and compair it to that you can visually see they are different. My 1406 with offroad kit and lowered floats does much better then it used to. I set my floats a bit lower then what the offroad kit called for, to help prevent flooding more.

Look for my post.JMaybe that is because you bailed on the Avenger before you got it setup right. My Avenger runs like a raped ape. So it is a miss guided comparison on your part.

My vote for Avenger also...

[Desert Beast]

im still tryin to work out the kinks in my avenger but from what ive already done it can only get better. and its already Great Googley MoogleyGreat Googley MoogleyGreat Googley MoogleyGreat Googley MoogleyGreat Googley Moogleyen.

I like my 1406, got the off-road kit, and the complete calibration kit. Took some work to get it set up right, but now it is better than anything Ive run before. Plus too when I got it there wasnt any off-road carbs that I knew about in my price range. So I am very happy with the 1406.

[88GW]

I vote for the Avenger. Outta the box way better than my Edelbrock. Even better now that I have made some tweaks.

[derf]

I had no problems with my Truck Avenger. I had some ignition problems that I had to sort out first but it runs fine now. I just bought a second one to run on my CJ project.

The Edelbrock carb is no different than their street version except for the spring loaded needles. That alone won't make the Edelbrock a true off road carb.

Derf: it has quite a few features that the performers do not have. Its vacuum secondary, not mechanical, the layout of the carb itself is changed quite a bit. its not just a performer with a offfroad kit.

I am going to wait to see a review of it before I say its crap. As judging before researching is a stupid way to do things.

[Frankenstien]

Well of your response to the fact I didnt try to tune the POS Holley I beg your pardon. Adjusted the Vacuum perfectly, changed the squirters six times, used different pump cams, adjusted fuel pressure etc etc. My carb had problems from the start and Summit Racing acknowledged that im not the first nor will I be the last. I also did extensive research on the web about the Avengers to which I found at least 8-10 posts in an hour about the same problems I was having with truck version. I never said Holley made a bad carb I just stated that I may have gotten a bad one. My Edelbrock on the other hand hands down blows the Holley away. Oh and I did stand my truck Great Googley MoogleyGreat Googley MoogleyGreat Googley MoogleyGreat Googley Moogley near on its rear bumper and let it sit there on hill for about a minute or so with no stumble or anything. Did some other climbing and offroading and again not one hesitation. The only thing I havent done is side angles at this point. So to each his own I was just saying I tried everything possible with the avenger and it would not respond.

They have since Carter released the design back in 1957. (The 1400 series is just a Carter AFB with an Edelbrock name plate)

Hell, even the "new" AVS is just a rebadging of the Carter AVS first used in 1966 and it's just a warming over of the AFB.

If you can show me one place anywhere that says what was changed from the standard design to make it off road capable, I won't be sold on the thunder series "off road" carb. According to: http://www.edelbrock.com/automotive/new2003/new_carbs.html the new Thunder series carbs are just AVS carbs with a secondary air valve, "distinctive black accented hardware", and other cosmetic things. The "off road" carb description only states the addition of the spring loaded needle and seats.

On the other hand, Holley describes everything they did with their carb here: http://www.holley.com/HiOctn/ProdLine/Products/FMS/FMSC/0-90670.html It describes a redesigned metering plate, you can see the tube connecting bowl vents to prevent dumping fuel into the venturies at extreme angles. It also comes with the spring loaded needles and seats. Hell, they state the angles at which it can perform. Holley worked with reps from the off road community in a trial and error effort to get the design right.

I haven't heard that Edelbrock has done the same. I'd like to believe that Edelbrock makes a great off road carb but I need to know how they did it. Anecdotal evidence of a few people can be very easily contradicted by the experience of others (i.e. success in tuning a particular carb or what angles someone was able to idle at) Some people get lucky. Others don't. I'll trust a built-from-the-ground-up-to-be-an-off-road-carb design myself.

I'm not saying the Edelbrock is a bad carb. It must be decent for people to use the basic design for over 40 years. I just don't see it as a great choice for off road use because I have yet to see one scrap of info about anyone testing it or otherwise explaining how it is supposed to be better than a street carb.

JasonIt still isn't a comparison, you had a bad carb and you never got a new one to see if it was actually the carb. This is my point you never had the holley running right so you can not say it is better. You can say the holley didn't run like you thought it should out of the box. You then say that the Edelbrock is by far a better carb which is a half butt comparison. You tried everything but a new carb which Summit would have sent you. I'm don't care either way which is better cause it comes down to personal preference, I'm just a little miffed at your half statements on comparisons.

I wonder if you would have had better luck had you traded it in on a new one. You wouldn't have been the first person to get a faulty piece of equipment right out of the box.

[Maynard]

Ive honestly never seen any carb work properly out-of-the-box. They all need to be fine tuned to what ever you are using it on, because every engine is different. I think it is expecting too much from the manufacturer to base your entire experiance on out of box performance. I found Edelbrocks instructions for their 1406 carb very informative. And after following it and calibrating, and off-road needle and seats, I couldn't ask for anything better.

[Stuka]

My performer worked out of the box. didnt have time to tune it. after i spent all weekend doing my wheels, dif covers, and performer intake. i just bolted the carb on, set the mixture screws to 2.5 turns, and drove it! smile.gif

Its tuned now, and has the offroad kit.

[Maynard]

I forgot, my dad bought a 1406 for his air-boat and he didnt have to tune it. Ok, from now on only believe about half of what I say :D ;)

I had to play with mine for about a week to get it running properly, my leaky Q-jet that it was replacing ran better. But now that it is all tuned up, that thing kicks butt.

[Frankenstien]

Yeah well I really wished the Holley would have ran well right out of the box. I intentionally bought the avenger to prove pop's wrong. It just so happens after tuning and tuning and tuning I could get the truck to respond at all. Not knocking Holley really just a little disapointed. Id rather be driving than tuning. Besides im not really quite as hardcore as some of you others who could probably really put this carb to the test. Hell Id be willing to go with someone in Dallas who has a hardcore crawler and do a little carb swapping and comparing. Would make an interesting article.
