Glad to see someone is still doing real 'engineering'..! Most carb's on the market still have the crappy straight or downleg booster, which as you say are garbage. People should really try an annular, there's a day/night difference in performance. The new Edelbrock 4150 is interesting, but I believe the metering blocks are just too complex for anyone to grasp and, fuel flow, who knows with how complex the blocks are...? I'd really like to try one of your smaller 4150's on a street driven hot rod, I don't mind paying for good engineering and quality parts. I'm thinking the 680 would suffice. Keep up the good work as there's still people who appreciate it.
I had been thinking about possibly building a carb, Holley style 4150 maybe a Dominator. And mill down leg annular booster nearly as large as the venturi with wire EDM to make the holes about .005"-.010" maybe . 015"-.020" after testing on multiple engines, some like more raw fuel into the cylinders I'm thinking make an attempt to get the fuel entering the cylinder in the form of a fog to basically gas like propane mixed with air. And having a idle circuit that uses a needle similar to a motorcycle carb allowing the position to change with a 1/16"-3/8",1/2" total travel with about 1/8" adjustment in that range without modification. Also having two screws, one changing the depth of the needle, the other changing the location of its position on the lever that opens/pulls it out and pushes it in. So the position is adjusted as well as the ratio of opening. I would like to build a 2bbl Dominator, around 600-650cfm, as well as a 550 and 700cfm. And a Holley inspired side draft carb. 4150 parts with the(basically )same bowl with the bowl either over or under the throttle valves the asymmetrical Holley bolt pattern to miss the fuel bowl.havent thought too much about that one. However the dominant 2bbl, Having a double pump two 30cc pumps with one squirting nozzle and one spray must nozzle. With the fully adjustable, to allow a little squirt 😂, then a mist, to a big squirt 😂😂and a bigger mist or a squirt and little mist or vise versa. *(Having a 4150 double pump with spray nozzle on the secondaries could be beneficial. Make the secondaries come in hard and clean on a street engine just pouring raw fuel into a engine, the fuel could just run into the nearest cylinder basic flooding it washing down the walls. I'm thinking have a CNC mill carve the parts from wax and high density foam and cast them in aluminum alloy. Although a titanium carburetor would be cool. But likely cost about $10k to build so bolts and air cleaner or velocity stack from titanium is all that is almost practical. And magnesium is a possibility, but if there is a fire there could be issues there! Having a fire you can't put our sux! But having a single barrel Holley looking side draft carb on a Harley with a 40-50, possibly 60mm. throttle valve with a single 30cc pump setup with a double nozzle , squirt in the center, spray from it's perimeter. With tiny screws allowing it to be adjusted. Restrict the squirt and allow the spray to take over. With the excess fuel being bypassed returning to the bowl. With the bowl being about 1.5"-1.75" x 2.5"-3.25" and 1"-1.75" deep. With the float and needle and seat inside , with a brass filter, and a 1/4" inlet, 1/4"-5/16" the bowl under the throttle bore. Using a fuel enrichment circuit instead of a choke. Allowing the idle circuit to supply about 20% more fuel and the booster getting about 20 jets additional fuel using a small electric solenoid and a small thermal switch. Requiring 12v 100 ma. (9-16v And about 2-4 watts of power, until it's warm The little actuator possibly supplying more fuel the colder it is, a long with a small passage supplying additional air. Basically like a tiny, 1mm carburator without a throttle it's either on or off! To have a fast idle on cold start up. With the down leg annular booster with ultra fine fuel delivery holes, possibly as small as .002" likely .005"-.010" and around 50-100 of them with the edge of the booster where the fuel and air leave at the edge. Have a rough surface, consisting of a 90°-120° cross hatch pattern about .005" Deep and about .0025" wide on a .005" center roughly . Making the edge surface similar to as having it wrapped with a ultra fine screen mesh. Like a window screen, allowing the air to mix with the fuel as it as the air flows across the cross gatch pattern Pulling the fuel from the small trenches. Creating a ultra fine mist similar to a stream of water hitting a window screen, or the water in a sink faucet going through the screen airaitor. The ultra fine hole pattern along with the Cross hatched edge should Have the fuel nearly vaporized as it leaves the carburetor. Maybe not the best for all our performance however tuned properly, it should perform well, and provide excellent fuel economy, and a E85-E100 carburator possibly having two boosters. A large thin booster and a small diameter thin booster being about 1/8" thick or possibly 1.5-2mm thick and 4-5mm tall. With the material being about .6-.8mm thick. With a 2.5-3mm tube feeding it fuel. The small one being 20 mm dia. bottom, and 23mm top the large booster 40mm and 38mm having a funnel slape and placed just above the venturi the bore beining large enough to compensate for their placement. A 65-70 mm upper most diameter, with a 45 mm venturi, having a 50 mm throttle valve. A booster being 3-5 mm thick it's not going to disrupt much flow. With all carbs having a similar dimensional ratio. A venturi being 5-6mm smaller than the throttle valves , and the velocity stack entrance being about 15mm larger at its largest point. I'm thinking having a long runner high ram intake , like a tunnel ram traditionally having 2x4 bbl carbs. A similar intake with the runners crossing sides entering a large wide plenum with 4 2bbl Dominator carbs to equal a pair of inline 4bbl carbs, with 2.125-2.275"throttle valves two 30 cc pumps each and capable of having 50 cc pumps with a spray or squirt nozzles and a bypass for excess fuel. A large diameter long intake runner from 2"x 2.5" at the head, to a square oval under the carburator with a 2.5"x3.125" with a long sweeping 12"-14" runner each 2bbl flowing about 570-625cfm with 2.125" throttle valves to the eliminator having a single valve, 2.5" x 5.375"-5.400" the 3/8"+ about .020"-.030" between the valves being removed. The flow being 700-730(+/-) a 500+ CID 8500 rpm engine probably will be required 2500 cfm is a lot for a naturally inspired engine. Or a large screw or roots blower pulling through them making 60psi on methanol and 20% spice! 🤏 just a wee bit! Taking about 300 hours to doing the boost maker the methanol playing intercooler! Enough rambling, it's basically just a dream. But dreams are free , (for now) I love Holley carburators, seems Holley is giving up on carbs, (everyone else is going Holley style, even edelbrock!!. It's a bit strange to me :•) Holley carbs are nearest to fuel injection the way I see it. Anyway love the videos , have an awesome day🎉‼️

Hi John, Do you have Shear boosters that would work in an 1850-2 ? Going to be using two on a Edelbrock cross ram on 401 cu” Ford. Thanks
