The Nitrous Holeshot 3500 stall converter are an excellent choice for vehicles with many engine modifications, particularly big cams that tend to reduce low end power and torque. The higher stall speed of this converter will launch the car in a higher rpm range where more torque is readily available, resulting in quicker acceleration. Nitrous Holeshot converters feature furnace brazed impeller and turbine, new precision steel alloy pump drive tube, new heavy duty needle bearings between the stator and impeller (not a thrust washer) and needle bearings between the stator and turbine. Other features include dual pattern 10.75 and 11.50-inch bolt circle, a new turbine hub, new springs and rollers in the stator and anti-balloon plates. The anti-balloon plates will allow these converters to stand up to the instant horsepower that a nitrous plate system delivers. Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. These are serious converters for serious performance street cars. To prevent contamination left from worn parts being circulated in your new components causing premature wear, we strongly recommend protecting your investment by adding a B\u0026amp;M transmission cooler with all new transmission installations. Listed converters are NOT to be used in trans-brake applications. Not for use in trans-brake applications.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNeedle Bearing Between Stator and Turbine\u003c\/li\u003e\n\u003cli\u003eHigher Stall Speed, Quicker Acceleration\u003c\/li\u003e\n\u003cli\u003eAnti-balloon Plate for Added Strength\u003c\/li\u003e\n\u003cli\u003eFurnace Brazed Impeller and Turbine\u003c\/li\u003e\n\u003cli\u003eFully Balanced and Pressure Tested\u003c\/li\u003e\n\u003cli\u003eSteel Alloy Pump Drive Tube\u003c\/li\u003e\n\u003cli\u003eB\u0026amp;M Quality \u0026amp; Durability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional Contents:\u003c\/strong\u003e New needle bearings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnti-Balloon Plate:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomotive Item Grade:\u003c\/strong\u003e High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Circle Diameter (in):\u003c\/strong\u003e 10.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e B\u0026amp;M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Transmission\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrank Pilot Diameter (in):\u003c\/strong\u003e 1.71\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmission Code:\u003c\/strong\u003e 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexPlate Bolt Circle:\u003c\/strong\u003e 10-3\/4\", 11-1\/2\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexplate Change Needed:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFurnace Brazed:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Type:\u003c\/strong\u003e Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Spline:\u003c\/strong\u003e 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Up Type:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLockup:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLockup Type:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Studs:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epart type:\u003c\/strong\u003e Automatic Transmission Torque Converter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Automatic Transmission Torque Converter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpline Quantity:\u003c\/strong\u003e 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStall:\u003c\/strong\u003e 3200-3500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStall Speed:\u003c\/strong\u003e 3,200-3,500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStall Speed RPM:\u003c\/strong\u003e 3200-3500 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSub Category:\u003c\/strong\u003e Transmission Hard Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque Converter Series:\u003c\/strong\u003e Nitrous Holeshot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmission:\u003c\/strong\u003e TH375\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmission Model:\u003c\/strong\u003e TH400, TH425, TH375, TH350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"B\u0026M","offers":[{"title":"Default Title","offer_id":45512271659143,"sku":"BAM20484","price":1009.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4008\/1543\/files\/20484_01_190ebe10-5862-45b2-968c-60c5bdd9d7d0.jpg?v=1788265159","url":"https:\/\/checkout.northernperformance.ca\/products\/b-m-nitrous-holeshot-3500-torque-converter-1965-91-gm-th400-425-1968-81-th350","provider":"Northern Performance","version":"1.0","type":"link"}
