Custom metering blocks and extra-large fuel jets specifically built for E-85 applications. Annular boosters provide superior air-fuel mixing for exceptional performance. The 20% larger fuel bowls use ribs to minimize incoming fuel foaming and control slosh. Nitrophyl floats shaped to avoid shutting off fuel flow during hard cornering. Jet extenders in the secondary bowl keep the jets covered in fuel under hard acceleration. Dual 50 cc accelerator pump circuits can satisfy large engine sizes. The one-piece 3.75”-tall aluminum body is a direct fit on either 4150 or 4500-style intake manifolds. The throttle arm includes all popular transmission kick-down take-off points. Vacuum ports for PCV, power brake, vacuum advance, and transmission modulator for a direct bolt-on installation. Built-in provision for a GM three-wire TPS. Four-circuit billet metering blocks use industry-standard-size screw-in bleeds and jets. The intermediate fuel circuit provides extra fuel just after the blade passes the transfer slot for incredible throttle response. Air bleeds on top of the carburetor provide a quick way to fine-tune each fuel circuit. The high-speed fuel circuit has two air bleed paths – one for lower and one for upper sections of the main well for greater fuel ratio control at high RPM. Two auxiliary idle-air screws allow users to change idle speed without moving the parked throttle blades away from their ideal position. The idle circuit features interchangeable jets and four mixture screws to create a smooth, clean idle, even with the biggest camshafts. Dual power valves allow leaner cruise and add fuel as you get deeper into the throttle for excellent street-performance driving. Protection circuits prevent backfires from damaging the diaphragms.\nPN 1309-E85 is a 950 CFM VRS-4150 Race series carburetor designed to flow 30% more fuel to match the needs of E85 ethanol fuel. Like all VRS-4150 carbs, 1309-E85 works great for racing or high-HP street applications built utilizing E85.\n\u003cul\u003e\n  \u003cli\u003eProvisions for TPS Sensor, multiple vacuum take-offs, and trans kick-down attachment for ease of use in street oriented applications.\u003c\/li\u003e\n  \u003cli\u003eCustom billet metering blocks flow more fuel to provide the ideal E85 AFR.\u003c\/li\u003e\n  \u003cli\u003eAnnular Boosters for superior air-fuel mixing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe Edelbrock VRS-4150 Race \u0026amp; Performance Carburetor (Part Number: ede1309-E85) is engineered specifically for high-performance applications utilizing E-85 ethanol fuel. Designed with custom metering blocks and extra-large fuel jets, this carburetor ensures optimal fuel flow and mixture for maximum power output. The dual 50 cc accelerator pump circuits provide rapid throttle response suitable for large engines, while the annular boosters promote superior air-fuel mixing, resulting in enhanced performance and efficiency. The 20% larger fuel bowls feature reinforcing ribs that minimize fuel foaming and slosh, ensuring consistent fuel delivery during aggressive driving or racing conditions. Nitrophyl floats are shaped to resist shutting off fuel flow during hard cornering, maintaining reliable operation under demanding circumstances. The secondary bowl is equipped with jet extenders that keep fuel supply consistent during hard acceleration, supporting high RPM operation. The one-piece aluminum body measures 3.75 inches tall and is compatible with both 4150 and 4500-style intake manifolds, offering a versatile fit for various high-performance engine setups. The throttle arm includes provisions for transmission kick-down points, facilitating seamless integration with transmission systems. Multiple vacuum ports allow for easy connection to PCV, power brake, vacuum advance, and transmission modulator, simplifying installation. Additionally, the carburetor features a provision for a GM three-wire TPS sensor, offering precise throttle control. The four-circuit billet metering blocks include industry-standard screw-in bleeds and jets, with an intermediate fuel circuit providing extra fuel immediately after the transfer slot for quick throttle response. Top-mounted air bleeds allow for fine-tuning each fuel circuit, while high-speed fuel control is enhanced by dual air bleed paths targeting different sections of the main well for precise adjustment at high RPM. The dual idle-air screws enable users to set idle speed independently without compromising throttle blade positioning. Interchangeable jets and mixture screws in the idle circuit ensure a smooth and stable idle even with large camshafts. Dual power valves permit leaner cruising mixtures and richer fueling under heavy throttle, optimizing street and racing performance. Built-in protection circuits guard against backfires that could damage the diaphragms, enhancing durability. Designed to flow 950 CFM, this carburetor is ideal for racers and street enthusiasts demanding maximum E-85 fuel performance. Whether for racing or high-HP street builds, the Edelbrock VRS-4150 E85 carburetor delivers exceptional air-fuel mixture control, superior throttle response, and reliable operation in demanding conditions.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eProvisions for TPS sensor, multiple vacuum take-offs, and transmission kick-down attachment for ease of use in street-oriented applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCustom billet metering blocks to flow more fuel for an ideal E85 AFR\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAnnular boosters for superior air-fuel mixing\u003c\/li\u003e\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: true\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: true\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":50978373861628,"sku":"1309-E85","price":1067.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/6518\/3740\/files\/24795c3e48e9a2e1fa7b067812e316e2L.jpg?v=1786665262","url":"https:\/\/diycustoms.store\/products\/edelbrock-vrs-4150-race-performance-carburetor-950-cfm-for-e-85-fuel-part-number-ede1309-e85","provider":"diycustoms.store","version":"1.0","type":"link"}
