I decided to run a 4150 carb on my combo for more street ability. Has anybody ran one of the 1050/4150 carbs against a smaller carb or a dominator? Do they make good power? I'm sure a dommy would make more top end hp but how much am I leaving on the table?

Did a 1050 annular for a friend and his SB Chevy made 620 peak w/the annular and only 6 more peak w/Pettis's house 1050 dommy FWIW but I think it is a 3-circuit and a 2 would be better on this combo and most for that matter.........

I ran a 1050 AN on my 511 on a tm6. Pretty much mirrored the performance of my six pack using a 4412 center. I was able to dial the 1050 in to run really great at cruise and actually get better mileage than the six pack. Both setups ran 10.90's through mufflers at 4000# race weight. I really like my 1050.

Fwiw, whenever I dynoed anything with the 4150/4500 adapter "upside down", the results were never great.

I had a Prosystems 1000 with the metering blocks and squirters setup like a 1050, and it was awesome. And against a 1050 4500 Thumper carb, it was .08 slower in ET and almost 2mph slower overall. I would highly recommend the newer 1050 model he has and a Thumper tune or I can give you mine. Do not do annular 1050 4150.

I ordered the pro form 67305 which is down leg boosters 1050. I don't know what the actual cfm is. I hope it's close ootb like my last pro form carburetor.

I'm with ya there although I never tested it personally, I've seen some guys say it works but my logic sez how could it.........These were NOS guys but still, a clean n/a signal and tune equates to a clean NOS pass all things being equal...........

Running huge carbs seems to be all the rage these days, so I won't even try and talk you out of it.
I'll just say that my one experience with one...... A qft-q1050......On a roller cammed, Indy headed 572....... was good. It made a few more hp than a Mighty Demon 850. A few like 3 or 30?

While I don't have experience with 4500 carbs, I recently went from a downleg 830 to an annular 1000 HP 4150. Right out of the box with only jetting and idle mixture adjustments, my 451 ran noticably crisper on the street with better throttle response and gained 2 tenths at the track.
It's notable that I changed the fuel delivery system at the same time, going from 5/16 to 1/2 line, and adding an auxiliary electric pump.

I run a 4150 style carb since I don't have intake gaskets for my 4500 intake.... and I don't want to ruin the ones that are presently on it. Have plenty of fun going 9.4's 9.5's.... CLASSIC Jay

I run a 4150 with a BLP BX4 main body on 434, BLP said it was 1050-1100 cfm. BLP has an "interesting" way of flow-testing their carburetors: "Carburetors are Dry Air Flow tested at 20.4” on a SuperFlow SF-1200 FlowCom flow bench using a 2” open hole spacer." Ever look at their flow ratings for significantly different carb sizes? Straight from their web site: - "750" 4150 w/ 1.405" Venturi 1.688" = 1030 CFM - " 850" 4150 w/ 1.590" Venturi 1.750" = 1060 CFM - " 950" 4150 w/ 1.405" Venturi 1.750" = 1060 CFM I suspect when you flow test carbs on a 2" open spacer that you're going to see less sensitivity to venturi & throttle size changes. If they were tested where the actual flow exiting the carburetor was isolated & measured (i.e., not dumped into a 2"-tall plenum first), the differences would be more apparent, and the max flow #s wouldn't be as high, either.
