I see a number of people looking but no comments.


If you save the data below to a "CSV" file you can import it into Excel and checkout the results from the cam test.

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
 

Stan go to www.powellcams.com on you tube powell machine inc, he participated in the cam challenge. He gets into great detail about camshafts, learned alot from his videos, realized that I was off on several of my cams, never buy a cam off the shelf!

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.

Stan

Re: Eric Weingartner LS Cam Challenge
 

These are the exhaust lobes for those cams.


Stan

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
 

For anyone interested a different way to look at the cam lobe profile,


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?


Stan

Re: Eric Weingartner LS Cam Challenge
 

My understanding is at the up coming PRI show, a number of the people who entered a cam in the challenge will be there in a conference room talking about the cam challenge. I will not be at PRI, but maybe if are you could stop in and to get a better idea of how they made their cam selection.
