New Edelbrock VRS-4150 Four-Circuit Carburetor

[BlueOvalFitter]

I wish I were still wrenching and building engines/hot rods. I would definitely like to try this new carburetor.

Looks like fun. I run Q-Jets on the street. My Vette came with one and I put one on the 4-4-2 which came with a 4-Jet.

I hope it's better than their Performer series carbs. I bought two different new ones back in the day and could never get either one to work right on two different Chevy engines. One a small block and one a big block. I spent hours on the phone with Edelbrock tech and even took it to several shops with no luck. Tried different jets and metering rods with no luck.

I will say that the Edelbrock Q-jet that I bought new is a great carb and is still on the 396 BB in my 70 Monte and has been for almost 25 years.

Other than nostalgia or a race series that prohibits electronics, why would you go the carburated route over an FI system?

Cost comes to mind... FI generally requires high pressure fuel delivery which can be a costly change to carb based vehicles.

New pump and a few fuel lines. Sure they cost more than the old engine-driven pump, but still not insane. Figure $200 for the pump and lines.

I certainly wouldn't do any form of new build with anything other than FI. The systems out there have just gotten too good to mess with carbs, especially on something you intend to daily drive or boost.

But, I guess they figure there's a market out there for it or they wouldn't have done it

I'd have rather they figured out how to eliminate those pesky power valves.

That would require Metering Rods like a QuadraJet or Carter/Edelbrock AFB.

I had the same problem but on a chassis Dyno.

The old Carter AFBs were good carbs, but the Performers seem to be hit or miss.
For the street, give me a Q-Junk. Lars is the man!

I prefer a good running Q-jet to most of the carbs out there.

Id prefer they figured out how to get half the stuff in their catalog cast - tried to buy a set of heads lately?

What in the hell is a carburetor?

What in the hell is a carburetor?

A fuel metering device guaranteed to deliver the wrong fuel air ratio 100% of the time.

 

[JeffKeryk]

What in the hell is a carburetor?

A fuel dumper.

This is.

the avs2 carbs get rave reviews.

I really should have used one on the hotrod 69 MUSTANG i built for my son Philip instead I used Holley, it still ran 186mph

Q-Jets are too complicated. Too many parts. BUT, when one is built and tuned correct, they can't be beat!

Lars Grimsrud reworked the Q-Junk on my L36 Corvette (3.36 Posi). With the aftermarket 16x8 Chrome Ralleys and 255/50/16 Comp TAs, 2nd gear throttle would start to get you sideways.
