  Here we have a brand new HP style,  Q1050 squarebore, 4 barrel, double pumper (mechanical secondary), 4150 style carburetor professionally built in my shop and set up BLOW-THROUGH SUPERCHARGER OR TURBO USE. This is one of my custom builds consisting of a new Quick Fuel Technology aluminum, contoured, HP style main body for maximum flow and enhanced booster signal. It will flow 1050 cfm with it's huge 1.580" venturi diameter, and is dyno-proven to 750+ horsepower without the boost, and MUCH higher numbers with boost! These parts are machined in Bowling Green, Kentucky. Please call the number below with any questions or concerns regarding your application.  

      It has been assembled with high-flow .130" needle & seat assemblies, 50cc pumps, #40 squirters, blue non-stick bowl and block gaskets, nylon bowl screw and needle & seat hardware gaskets, and vent baffles. The jetting is 86 up front with a 6.5" Hg high-flow power valve, and 94 in the rear with the power valve circuit blocked. The mounting gaskets are included as shown. 

   Here's a list of features;

  New QFT polished lightweight aluminum main body with screw-in air bleeds. .070" idle and .025" high speed bleeds installed.

  Annular booster inserts machined from billet aluminum and red anodized to match the base and inlet fittings. These precision boosters have 12 holes (versus 8 for the Holley cast piece) for better fuel atomization and more midrange torque and horsepower.

   Red anodized metering blocks that are custom calibrated for maximum performance.

   New red anodized billet aluminum baseplate specially designed with channels to prevent fuel leakage from the end of the shaft bore under boost.

   New teflon coated throttle shafts, stainless steel throttle blades, and loctited button-head screws for increased flow due to decreased turbulence.

   New lightweight aluminum racing style fuel bowls with dual inlets and sight windows (will not yellow). No more fumbling with sight plugs!

   Red anodized inlet fittings and plugs to match the base. Uses a standard Holley model 4150, inverted flare fuel line with 5/8"-18 flare nut.

   Jet extensions and notched float in the rear to prevent fuel starvation during a hard launch.

   Crush resistant nitrophyl floats front and rear.

   Rear idle speed adjustment screw for fine tuning the 4 corner idle.

   This carburetor weighs about 7 1/2 lbs., while a typical cast zinc carb weighs in at 11 to 13 lbs.
