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.

Stan

Re: Eric Weingartner LS Cam Challenge
 

I currently plan to attend PRI. I missed the first one in nearly 30 years in 2022, while I was recovering. Don't intend to miss any for a long time. I plan to sit in on several seminars, they're often quite good.

Re: Eric Weingartner LS Cam Challenge
 

As a followup. I find it interesting how at around 4900 RPM almost all of these have the torques come so close together.

Re: Eric Weingartner LS Cam Challenge
 

Average Cam Specs for Eric's Top 5 Finishers
LCA 110.5- Adv 3.8 - ICL 106.7 - ECL 114.3 - Intake 0.050" 239.46 - Exhaust 0.050" 254.20 - IVO 13.50 - IVC 45.96 - EVO 61.84 - EVC 12.30 - Overlap 25.80 - Intake Lift 0.642" - Exhaust Lift 0.640"


Average Cam Specs for My Top 5 Finishers - I used a different method of scoring
I have 4 of Eric Top 5 in My Top 5. One of his top 5 doesn't make my Top 5 and someone outside his Top 5 moved into My Top 5
LCA 109.7 - Adv 3.0 - ICL 106.7 - ECL 112.7 - Intake 0.050" 241.86 - Exhaust 0.050" 254.60 - IVO 14.64 - IVC 47.22 - EVO 60.38 - EVC 14.16 - Overlap 28.80 - Intake Lift 0.646" - Exhaust Lift 0.644"

Stan

Re: Eric Weingartner LS Cam Challenge
 

This was at PRI. While it is about Eric's Cam Challenge. There is some good general engine / cam information discussed.

Near the end of this video Eric shows the results of testing the Victor, Victor Jr and the Holley Split ported by Charlie Servedio. Using the Brodix BR3 heads and the Texas Speed cam.
