Re: Eric Weingartner LS Cam Challenge
Just encase someone is interested. Over on another forum we have a long thread going about the cam shootout. I don't have any of the newer sims. I do have the older Desktop Dyno2003. After I selection / guessed at what I believed the cam should be (I posted those specs on that forum before the contest) I did a sim in Desktop Dyno2003. That is the right hand one in this picture. I later changed my cam specs to the Erson Cam DR specs. That is the center chart. On the left is what I have, which is only part of the Erson Dyno sheet.

Re: Eric Weingartner LS Cam Challenge
This graph shows the general shape of 4 Intake lobes, which were generated from their Cam DR reports. The lobes are basically centered so it doesn't reflect where valve events are relative to the other cams shown.

Re: Eric Weingartner LS Cam Challenge
These are the exhaust lobes for those cams.

Re: Eric Weingartner LS Cam Challenge
Remember the result of what I generate, are only as good as the data and the number of data points that the cam reports have.
These are for the BTR #1, Daniel Powell #1 and Daniel Powell #2. Stan |

Re: Eric Weingartner LS Cam Challenge
How did each of the cams that were tested with the different heads, intake manifold, headers, and increased CR do?
