C&S and CSU are the most popular and well know blow-thru carb builders. I'm sure at some point those guys will start playing around with these edelbrocks once they become more common. CSU uses a custom billet boost referenced power valve along with modified metering blocks to achieve good results where C&S used standard power valves that are sprung backwards and modify the rest of the carb to use their own billet venturis and they are also famous for their "aerosol carb" if you have never heard of them you should check them out.
No doubt, the most adjustable 4150 out there, that can be tuned for every motor. These carbs are finally hitting the shelves and are available, but I have yet to see one video/review about 'real world' drivability on a performance street engine. There's no doubt these carbs will make power on a race or street engine at full throttle with the annular boosters and main body venturi shape, but again, real world, performance street - out-of-the-box performance would be nice to know. Have you installed this carburetor on a street rod yet?
Thanks. A few things. You are correct it matters the horsepower for a few of these things. Usually you don’t have to worry about things like boost referenced power valve and drilling out some of the metering block ports for moderate boost, like under 12-15 pounds. Most street applications can skip a lot of these steps. And yes, when you go past that it gets way more complicated generally. It’s cool that it has no choke (some others are like this too) and solid floats. Good video.
I was one of those who commented on a Blow Thru application. Boost reference power valves are the main thing this carb will need . You will have to block off the power valve "Check valve " to prevent boost leak also . Awesome carb, Has plenty of potential of making big power in a Blow Thru app.
But yeah for sure it’s got a ton of potential. Hope to find out soon what metering blocks might be available. That will really let us know just how much power one could support.
@@MuscleCarSolutions If you are interested to see how many cars are actually running a Blow Thru app, Face Book has a page called " Blow Thru Mob" Tons of fast cars going faster than they should. BTW . Great explanation of what is needed to convert this carb. Thanks 👍
That 650 you got is in deed a annular booster type. The leg shape of the booster does not determine its type but how is discharges the fuel. (Look inside at 3:06)
That's one cool looking carb for sure my Holly 850 double pumper is only a year old, but I see one of these in the future for my 396 68 Camaro another great video keep them coming
It’s a pretty loaded carb. Cool to see something new when all signs point to anything internal combustion engine related supposedly going away! Thank you John!
@@MuscleCarSolutions my little old 350 with 9.5:1 cr really loved the the 650 avs2 so maybe I'll get the 650 if it has annular boosters with mechanical secondary
@@MuscleCarSolutions thanks for the info, I tried holley downleg brawler carb and my 350 didn't do to well below 3k roams, had to ez into the gas so it won't bog down
You will also need to consider the fuel ring size in the annular booster as well as the feed hole size. The ID of the booster in ratio to the venturi is also important.
Nope. I’m not redesigning the entire carb. The venturi and boosters have already been sorted. If you’re referring to the pin size that feeds the booster, yes we talked about it in the video.
@@MuscleCarSolutions I'm referring to building it as a blow through. I build blow through and blow through parts for a living and have done more R&D in the past 30 years than I can recollect. LOL.
@@MuscleCarSolutions fuel ring is the fuel channel behind the annular insert and the banjo. feed holes are the 8-12 holes that distribute fuel around the circumference of the booster. Pin size, yes. gas I'll use .160-.170 e85 I'll use 180 methanol .180 plus. cross channel on gas you will want .155 to .162 and bottom of the main well .155-.160 depending on power level. twin needle bowl is a must above about 1100 hp on gas. fuel delivery in the whole system is paramount.
My 1-month-old AVS2 has a hole in the booster. I'll be calling Edelbrock tomorrow and I guess we're going to test how great their customer service is. This is so disappointing. Carburetor is taking apart and it's like damn, do I even put it back together or let it sit like this while I wait for a new booster, one that hopefully I won't have to pay for. Anyway I posted a quick two and a half minute video on my channel that shows exactly what's going on. I really do owe you for therapy I appreciate you LOL

No. The 650s do not come with annual boosters. Only the 750-950.

awesome, We have been asked a bunch too. love this explanation
You might see a new sticker on my tool box in these videos………
@@MuscleCarSolutions LOL!!!! I did not see that until now!!! 💕💕
Representin’ the brand! 😁❤️
Very informative. Thanks for another great video!🍻
Thanks buddy. Enjoying your LS truck build!
On draw through (roots style supercharger) why wouldn't you boost reference both power valves rather than just the primary? Thanks.
What was the brand and model number of the drop base air cleaner? The one I bought interferes with needle and seats.
This one; amzn.to/3UQhtLa
Will Holley dual needle and seat float bowls work on this carburetor?
No

Hole on the booster?
Hey Bone, about 95% of the video went over my head, lol, but still really enjoyed it, happy Thanksgiving weekend buddy, catch you soon
It does take awhile to learn these but once you have that level of tuning, you get spoiled by it quickly! Happy thanksgiving to you also!
@@MuscleCarSolutions 👍👍
So if i wanted to build a 500hp blow through would this carb support it without the meetering block change?
Potentially, but the other slight modifications will still need to be made/addressed.
Could you run this carb on a roots style blown engine?
Sure.
What brand is that base, mine needed modification to clear the needle and seat.
What base?
@@MuscleCarSolutionsthe air cleaner base
If you want to grab the market share from Holley why would you make it cost more than a Holley lol!
I think you’d better check again. The ultra XP is about the closest that Holley makes to the Edelbrock. The Edelbrock is $250 cheaper. lol!
It would be a lot more common if the price for a blow through were not 1000 bucks and up
They are for sure expensive. But a good purpose built one is way more than $1000!
@@MuscleCarSolutions exactly which puts it out of the budget of most backyard builds. Hell my whole car only cost 💲 1200.
@@yeahididit9054 having fun can be done cheap. Making power costs money. Good thing all these Edelbrock carbs are under a thousand!
Think edelbrock hires Q/A from Holley? Neither very good at their job. Thanks
What’s Q/A? Thanks.
