For our easy Six-Step Titration Method, you will need:<br /> 1. 100 ml. graduated cylinder & stopper<br /> 2. Sample of test E85 fuel<br /> 3. Distilled water<br />
  38. 38. Six-Step Water Titration Method,<br />for E85<br /><ul><li>Step 1:</li></ul>Fill the cylinder to the 50 ml. mark with the test fuel.<br />
  39. 39. Six-Step Water Titration Method,<br />for E85<br /><ul><li>Step 2:</li></ul>Add 48 ml. of distilled water.<br />
  40. 40. Six-Step Water Titration Method,<br />for E85<br /><ul><li>Step 3:</li></ul> Put stopper in top of cylinder. Shake vigorously to mix the water and fuel. Allow it to stand. <br />
  41. 41. Six-Step Water Titration Method,<br />for E85<br /><ul><li>Step 4:</li></ul> Pull stopper out slightly to allow pressure buildup to escape. Reseal and allow to stand for 15 min. <br />
  42. 42. Six-Step Water Titration Method,<br />for E85<br /><ul><li>Step 5:</li></ul> Write down the overall Volume A and the separation line Volume B.<br />
  43. 43. <ul><li>Step 6:</li></ul>Apply this formula to determine gasoline content:<br />Percent Gasoline = 2.1 + 1.94 (Volume A – Volume B)<br />2.1 + 1.94 (93-86)<br />2.1 + 1.94 (7)<br />2.1 + 13.58<br />Percent Gasoline = 15.68%<br />To find the ethanol content, subtract the percentage gasoline content (15.68) from 100:<br />100 – 15.68 = 84.32% or approx. E85<br />
  44. 44. <ul><li>Engine Modifications</li></ul>Protect your engine and take full advantage of the power-making capability of E85 fuel:<br /> 1. Utilize ethanol-compatible motor oil<br /> 2. Adjust engine static compression ratio<br /> 3. Increase engine dynamic compression<br /> 4. Adjust air/fuel ratio<br /> 5. Adjust spark timing<br />
  45. 45. <ul><li>Racing with E85</li></ul> Not only does E85 vary in ethanol content by the time of year and from pump to pump, but the 15% gasoline portion also affects engine performance and fuel system requirements.<br /> While pump E85 has a nominal octane rating of 105 (R+M/2 method), we strongly recommend that you find a supplier of “E85 Racing Fuel”. The fuel should have a consistent and high (85%) ethanol content and the petrol should also be a high grade racing fuel. This will protect your engine from varying octane levels and air/fuel mixture requirements.<br />
