I&#39;m in the process of a lengthy experiment and calculations regarding acceleration that will (hopefully) take the engine map, torque converter lock up, etc. into account. It&#39;s a very very tough and complex problem and, like you, I have a living to earn!King of the Roadhttp://www.blogger.com/profile/06841601144107400103noreply@blogger.comtag:blogger.com,1999:blog-26744483.post-19956360166121392052009-07-28T09:23:21.174-07:002009-07-28T09:23:21.174-07:00You are WAY above my head with your calculations, but it seems odd that there is no discussion of gearing. Does your analysis include your 6-spd ATM?
