Edelbrock VRS-4150™ Race & Street Carburetors

[@elreyyakko]

Good job Edelbrock. Filling in the void that will be left when Holley goes full EFI.

[@jerrycoon3369]

Wow! Looks like Edelbrock really did their homework on these. Great adjustability. Nice job!

[@tinkeringtrucker5196]

Cool, edelbrock made a holley

[@randylear8264]

More than that. Did you watch the video?

[@captiansnickers5201]

Well Holley's going to stop making Holley 😂

[@johnbehneman1546]

THANK YOU SO MUCH!!! THIS CARB HAS ALL THE BASIS COVERED!!! THANKS FOR SHARING!!!

[@williamsanders468]

Amazing carburetors great for any build that you do plan on driving on the street and drag racing on the weekends.

[@zAvAvAz]

Ok, now i want a 4500 series design

[@oldcarguy6863]

Looks like a killer carburetor

[@save16thave]

The guys from Two Lane Blacktop would love this carb, they were always changing jets.

[@jamesspain5049]

Check the points. Yep, still there

[@DRaysShop]

It's a Holleybrock... 😀

[@jessicaembers924]

Jimminy, that's a lot of fricken jets!

[@jamesspain5049]

After playing with old school double pumpers on a tunnel ram and street driving it, I see so much about these that are just awesome. With a O2 sensor and some thinking involved, these are going to be unbeatable. I am tickled I haven't bought a Carburetor for my simple old school dual point big cammed 460 project as they just made the sale.

[@stevoschannel4127]

Need to pull the bowls for jetting still…are parts interchangeable with a holley? AND where is it made???

[@liberaltears6328]

Uncle Tony's Garage likes it

[@SmackeysGarage]

I'm looking forward to trying one of these out on my 390.

[@halseyknox]

Just left a reply scenario for the 650 on 428FE......did you ever get one for your 390

[@barneymiller7894]

Ok Edelbrock, you've got my attention 🧐

[@css-centralspeedsupply103]

We are excited for these!

[@IggyEGuana]

Great job Brent!

[@BOOT]

Looks interesting, hopefully get to try one out someday.

[@johngossert3908]

Looks great, but most people including Racers, can’t adjust a regular Holley correctly! Wait until they start monkeying with this piece! Lol

[@vinnylc]

I know, when im at the track i cringe seeing people change main jets for WOT, thats power valve jets 101

[@mickangio16]

But most Holley carbs don't have replaceable power valve restrictions. My complaint with Holley is that ALL Holley carburetors SHOULD have replaceable power valve channel restrictions AND replaceable idle feed restrictions. The additional 1/2" height of the Edelbrock is a drawback to me and I'd like to see a version with an electric choke with an easier to access fast idle speed adjustment than the Holleys and adjustable choke pull off. Holley needs to step up their game fer sure- especially for what they cost$$$.

[@edvisme]

I'd love to try one of these.

[@saml3902]

excellent tunability something I had to previously go to a carb builder to get. Looks like a lot of tricks from brasswell and BLP

[@vinnylc]

ya agreed, braswell is king of carbs i still want a custom one from him someday.

[@TheMilchTube]

Where the hell can I buy one ?!

[@huskynox1]

I just picked up a new 1307 (750). Very nice carb, Very smooth power compared to the double-pumper its replacing, I attribute that to the very nicely done Annular Boosters. The only thing that was way off was the transition, it went from idle 13.0AFR to 15AFR, causing the motor to cough and stumble until the primary booster came in. I had to change the idle bleed from a 70 all the way down to a 42. I also tried a 36 IFR (from the stock 31), which basically had the same affect with the standard 70 idle bleed jet. I also changed the standard 4.5 Power Valve to a 8.5. The engine (445 Ford FE Stroker, Edelbrock Al Heads, RPM Performer, Comp Cam (230/236@.050, .530 lift) pulls clean and hard thru the power band at 12.5AFR, but at light load (cruise) it is pig rich at 10.5. I'm not sure what dial to turn to lean 'cruise' out? I've called Edelbrock Support twice with them telling me they have no literature on these carbs, so they have no idea what to do. This is pretty concerning and disappointing. Edelbrock? Anyone who has knowledge? Advise would be greatly appreciated.

[@markh8301]

Try a bigger carb? 750 CFM sounds too small for a 440 CID motor.

[@halseyknox]

Any update on your scenario and your stroked 445 ford. Interested in the 650 for my FE428 mild build for the street

[@huskynox1]

I went with a Quick Fuel 750 w/annular boosters. The same issue was there with the low rpm transition to the booster, what cleaned it up was changing the high speed air bleed from the stock 33 it came with, to a 38. A bit counterintuitive, I would of thought the low speed bleed would of affected that part of the curve, but not true. After looking at other big block jetting, it seems guys are running 40 or above for the high speed air bleed, so my finding seems correct. You could try this setting on the Edelbrock. I'm happy with the Quick Fuel, but it is expensive at $1100.

[@grizzly766]

So is there a tuning class. E4150-101?

[@nnperformance76]

commented & liked & subscribed. awesome new technology for carbs. lots of older stuff is not getting the tech updates. great job. 👍 what about ignition? any ideas?

[@UcantBeSerious03]

oh wow I must have one or two

[@rebelscumspeedshop]

The way the venturies are wide like a salad bowl I'm willing to bet the CFM ratings are actually closer to advertised.

[@michaelcannizzo1076]

Any plans to add a vacuum secondary version?

[@ryantucker5903]

When can they be bought and where

[@alrui]

I assume (hope) it's made in the USA?

[@69dodgecharger440]

Extra height only thing for me not much room with nitrous plate and air cleaner! Will buy one for my other car! Lots of cool things ✅

[@shaneyoung5567]

Will there be kits to convert it to blow through?

[@ChapmanAutomotive]

What is pricing. And can they be made blow thru?

[@vinnylc]

yes very easily, but you need to change the bleeds accordingly and add vent tube extensions for the idle signal to be stable

[@davidvonanderseck8649]

Wow nice

[@halseyknox]

Like was already commented there a lot of jets.....as cool as the carb is I'm a little concerned if or how much the carb has to be tuned for mild build street use....aka the 650 on a 428 Ford.....simple adjustments no big deal but would or could these adjustments open sorta Pandora's box to all those jet adjustments.....

[@mrmoparrr]

Also 2ndary optional Linkages “”

[@bertmorlas3534]

Atta boy!

[@Lagrange1186]

I think the only thing not built into this from the start was capabilities for blow thru applications. But wow I can’t wait to see how this does on independent dyno testing. What’s the price point on this?

[@vinnylc]

with basic mods this has no problem as a blow through.it already has dual fuel inlets per bowl and brass bleeds through the carb to allow custom sizes for tuning. just add some vent tube extensions, with the annular boosters this comes with it should be able to keep up no problem, dog leg and straight leg boosters no so much but this should be fine.

[@vinnylc]

wow at first i thought it was a ripoff Holley and it kinda is but this looks really nice. this is basically a modified Holley with all the tricks you would have to buy separately but with the Eddy its standard. if you really know how to tune a carb this is a one stop shop purchase. the fact that you can change Boosters on the fly without sending it to a carb specialist because of the required tools to press them in and out properly, this makes it more user friendly than the Holley. They really did their homework on this and im waiting for it to come available so i can by one for my BBC. the ONE thing i wish they would have redesigned is the way jets have to be changed, the need to take off the fuel bowl and swap jets with the risk of leaks is not only a pain in the ass but can be a danger at the track when making changes. Maybe drill 2 holes in the fuel bowl with plugs so you can stick a jet tool with a magnet inside without removing the bowls and breaking seals???? but I this is still a nice product and cant wait for mine. And for the people asking about Blow through Applications yes this will work you just need to make sure the jets and bleeds are calibrated correctly and add vent tube extensions to the top tubes and you can run boost. Thats all that really separates a standard race Holley from a blow through. You can even run this on Alky if you want to do the math and make custom bleeds and jets.

[@TheAaronmh]

Will there be a USCG approved marine version?

[@pauldhiman8369]

Holley

[@tonycolca2241]

Is edelbrock going to come out with this carb with electric choke

[@crazyhorse3275]

I just a video the carburator starts very good on cold weather. I'm going to buy this one I was tempted to convert my 540 big block to EFI but I have friends with those systems they are coming back to carburator. This one in particular. Holley will stop making carburator they will concentrate on EFI 😢😢😢

[@Oldfordshit]

Eldabrock been beating Holley for ever now they really just knocked it out of the park awesome carb I need one

[@f430ferrari5]

Unfortunately for Holley they made various acquisitions at the wrong time. They bought Hooker Headers, Weiand, Flowmaster, MSD, etc pre 2008. Holley filed for Bankruptcy in 2008. Many of the SEMA companies are struggling along. This industry could open back up more of emission controls were lightened up. Any car 30 years or older should be smog exempt. Maybe even 20 years for limited production models. Waivers should be available if you drive less than 500 miles per year.

[@nelsonyurok]

Noice!

[@joe-hp4nk]

People are going to be in more trouble trying to tune it than you can shake a stick at.

[@bryandouglass9997]

Can you blow-thru this carb?

[@jacobnorth8642]

I heard they specd a 5/16 " air cleaner hold down instead of 1/4" just for blow thru setups

[@rebelscumspeedshop]

Lol yey.. Edelbrock finally gets complicated..lol

[@walkinshawkiwi]

Its just a Holley copy

[@joe-hp4nk]

Too funny, there's more tuning than you can shake a stick at.

[@robpeters5204]

Looks like edelbrock took a page out of the Chinese handbook. Just copy Holley carbs.

[@barneymiller7894]

Kind of, but you'd have to go to a custom built Holley to get the same features 🤷‍♂️

[@PerformanceEngines]

they are now the same company

[@graydonjones6912]

So you just copied a holley carburetor?time to hire someone who can come up with a new carburetor not just copy another piece and say that you have improved it

[@Kokaiinum1]

Okey shit... Iam going EFI... Iam going to be an old broke man before that carburator Will be jettet right on whatever i build, Jesus christ thats alot of jets.

[@jetmr_5043]

Man, I Wonder who invented the 4150 and already has used most of these features… Hmmmmm

[@KingJT80]

This carburetor is actually taller than that one company which is interesting

[@mikewilliams344]

Barry grant. NHRA screwed the man.

[@Chevysrule454]

So edelbrock copies holly. Hmmmm wonder how holly feels about that

[@anthonyreyes-brown467]

Well from what I hear holly is ending production on they're carburetors and going strictly efi so I don't think they care. We should be saying thank you to edlebrock for filling that void

[@chrissybert6543]

There will be no more production of carb applications from holley. I have been trying to find a split plane race manifold for carb for a ls3. Can't get it, they are not making it anymore even though they are still for sale in jegs and all the big parts salers.
