TORK TEK CUMMINS HIGH PERFORMANCE OVERFLOW VALVE / BOLT – OFV060

<p>Description Warranty Information TORK TEK PERFORMANCE OVERFLOW VALVE LOW FUEL PRESSUREWITH YOUR AIR DOG or FASS PUMP? INCREASE YOUR HORSE POWER AND FUEL PRESSURE WITHYOURHOTP7100 CUMMINS * OFV060HP Use withsuper street performanceCummins trucks. * Fuel pressure range of43 to50 PSI. * Raises fuel pressure at full power. Do you experience low fuel pressure at wide open throttle (WOT) and just accept it as normal? Have you ever thought that low fuel pressure gives your competitor an edge? Anthony Reames, the technical manager at Air Dog, asked us to solve the low fuel pressure problemwith theBosch P pump. Cummins owners report that the fuel pressure drops to as low as 16 PSI during full throttle runs. We jumped on this technical request because we thrive on a challenge. Solving problems is what Tork Teknology is all about. The first thing we did is throw all assumptions out the window. We found that in most cases, they can be very misleading. Our slogan, that we live by, is "one good test is equal to a thousand expert opinions". This is how we attack a problem. The OFV060HP has thethird smallest orifice forhighly modified Cummins diesel engines. Your truck is street driven. Your fuel system, engine and turbo have been modified. Your horsepower will be in the 500 to 600HP range. This valve is for superhot Cummins performance trucks using an AirDog, Raptoror FASS pump. Yes it can be used for P pump conversions on the 24V Cummins. What fuel pressure shouldyou be running?Here is a general rule to determine the fuel pressure you should be at. Multiply the governor spring rpm (in thousands)times 10. In other words, you want 10 PSI of fuel pressure per 1000 RPM of governor speed. If you installed a 3K governor kit, you need a minimum of 30 PSI at full power.A 4K kit requires 40 PSI at WOT.5K equals 50 PSI. Remember, this is at full power, not idle or cruise. Fuel pressurewill bein the43 to50 PSI range if youadd the 40 PSI spring. The standard spring will limit the fuel pressure you can reach. If you are using the original Air Dog pump, it is factory set at 30 PSI. If you want higher fuel pressure, you will have to install a 40 PSI spring. The AirDogI and II use different springs to achieve higher fuel pressure. They are not interchangeable. Please note that you will not achieve higher fuel pressure by swapping out the spring. You have to fix the leak first. Do notuse the HPvalve on a stock fuel system! This valve will raise pressure spikes to the point that the stock fuel filter canister will blow a seal. The valve is intended for Cummins P7100 trucks using a FASS, Air Dog or high volume, performance fuel pumponly. 1 YEAR WARRANTY</p>
