With the Dynojet, that weight is only about 2600lbs.<br />So if you are tuning a car on the Dynojet, you are tuning the engine to push<br />around 2600lbs. That's fine on the dyno, but as soon as you get the car on<br />the street, the car probably weighs closer to 3500lbs. So the engine you<br />just tuned to push around 2600lbs is pushing around about a 1000lbs more<br />weight. This additional load on the engine is going to cause the engine to<br />detonate.<br /><br />Whereas the Mustang is a loading dyno. We have an electromagnetic brake<br />called an Eddy Current that allows us to apply additional load on to the<br />vehicle. We also have a patented program called Road Load Simulation. With<br />this program, we can simulate the weight and aerodynamic drag of the<br />vehicle. So when you are tuning the engine on the dyno, you are tuning it<br />to the amount of load that it normally sees on the street and therefore it<br />won't detonate when on the street.<br /><br />As for the Dynojet reading higher than the Mustang, that is correct. But<br />if you look at almost all of the other dyno manufacturers out there, they<br />read numbers closer to ours. About 6 months ago, there was a magazine<br />article in "Sportscar International." This article was an interview with<br />Mark Dobeck, the founder and original owner of Dynojet. In the articles he<br />goes on to explain when he made his first motorcycle dyno, they weren't<br />getting wheel horsepower numbers that he thought a certain motorcycle should<br />get. So he incorporated a fudge factor into the number. That fudge factor<br />has been present ever since in all of their dynos. That is why they tend to<br />have higher dyno numbers than other dyno manufacturers.<br /><br />If you have any other questions, please let me know.<br /><br />Thanks,<br /><br />Tim Gentil<br />Sales Engineer<br />Mustang Dynamometer<br />2300 Pinnacle Parkway<br />Twinsburg, OH 44087<br />Ph: (330) 963-5400 Ext. 211<br />Toll Free: 1-888-468-7826 ext. 211<br />Fax: (330) 425-3310<br />Email: tim.gentil@mustangdyne.com<br /><br /><br />Comments: WOULD LIKE TO KNOW THE PRIMARY DIFFERANCE BETWEEN A MUSTANG<br />DYNO AND A DYNOJET. I HAVE BEEN TOLD BY VERY RESPECTABLE RACERS AND TUNERS<br />THAT YOU COULD POSSIBLY DETONATE ON A DYNO JET DUE TO NO LOAD PLACED. ALSO A<br />DYNO JET GIVES RWHP RESULTS 10% HIGHER THAN A MUSTANG DYNO.?<br /> <br /> <small>[ December 18, 2007, 01:04 AM: Message edited by: warhorse58gt ]</small> <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>r3dn3ck</b> <br /><small>Member # 3192</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2007,11,20,11,10,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> I just did a back to back run on both types and got exactly what you should expect from a competent dyno operator... identical results.<br /><br />I got 278/332 on the mustang 750 and 280/333 on the dynojet.
