HOLLEY, QFT 750 HP, 4150, BLOW-THROUGH SUPERCHARGER OR TURBOCHARGER USE ONLY

Description: Here we have a BRAND NEW HP style, 750 squarebore, 4 barrel, double pumper (mechanical secondary), 4150 style carburetor professionally built in my shop and set up for use with a BLOW-THROUGH SUPERCHARGER OR TURBOCHARGER. This is one of my custom builds consisting of a new Holley aluminum, contoured, HP style main body for maximum flow and enhanced booster signal. It will flow approximately 800 due to the HP style contoured body, but will still respond better than the old 750. They will support 550-850 horsepower depending on engine capabilities and how much boost is applied. It is not recommended for use on engines making less than 500-550 horsepower. I have a 650 available for lower output. These carburetors are assembled by me, one at a time, using 100% Quick Fuel and Holley parts. The parts are machined in Bowling Green, Kentucky. Please call Steve at seven24,523, two947, or message me through the "ask a question" link with any questions or concerns regarding your application, and available options and pricing. I can set one up to closely match your engine. This is as close as you can get to the Quick Fuel Q-750-BAN that Summit Racing sold for $1232.95, or the Demon MAD-750-BT for $1009.95!! It will perform the same, is built with all Quick Fuel and Holley parts, but mine costs far less! It has been assembled with high-flow .110" viton tipped needle & seat assemblies, 30cc pumps, #31 squirters, non-stick bowl and block gaskets, nylon bowl screw gaskets, and vent baffle. The jetting is 74 up front with a 4.5" Hg high-flow power valve, and 84 in the rear with the power valve circuit blocked. The mounting gaskets are included as shown. I do not recommend more than 8-10 PSI of boost with this carburetor. They are best suited for use in the 4-10 PSI range. Here's a list of features; Holley HP polished, lightweight aluminum main body with screw-in air bleeds. .070" idle and .030" high speed bleeds installed. Annular boosters for better fuel atomization and more mid-range torque and horsepower. Annular boosters are also the absolute best choice for use with a blow-through carburetor. Performance aluminum metering blocks that are custom calibrated for maximum performance. 4-corner idle for fine tuning with a performance cam. Heavy-duty, clear anodized, billet aluminum base plate with teflon seals and the vacuum ports plugged. Teflon coated throttle shafts and loctited button-head screws for increased flow due to decreased turbulence. Lightweight aluminum racing style fuel bowls with sight windows (will not yellow). No more fumbling with sight plugs! Inlet fittings to match the base plate. Uses a standard Holley model 4150, inverted flare fuel line with 5/8"-18 flare nut. This carburetor weighs about 7 1/2 lbs., while a typical cast zinc carb weighs in at 11 to 13 lbs. Please email or call me at my shop with any questions, as I will be glad to help you with your setup. I can be reached at 7two4,523, two947 from 9 am 'til 7 pm, eastern standard time for tech or service help. I welcome all potential bidders to check my feedback. My feedback from carburetor and parts sales is 100%, and I've sold hundreds in the past few years. I am the owner/operator of a one-man shop and my carbs are built with pride one at a time. Please see my other auctions for more great deals. Thanks, Steve
