I thought that I would post this chart for anyone thinking about doing a cam upgrade.

Please note that I cannot take credit for this. (only for posting)

Steve Cole (designer/owner of TTS Mastertune Turner) did this comparison for sole purpose of mapping and base tunes for each cam. Also a member over on the CVOharley site, put it into a graph that is easy to read.

One thing to remember is that it doesn't show where the HP/Torque numbers start, just overall numbers.

Great info folks!

NOTE: ALL THE TESTING WAS DONE ON A 2015 CVO STREET GLIDE MODEL. ALSO FULLSAC "D" X-PIPE, FULLSAC 2" CVO CORES, STAGE 1 FILTER AND A FULL TUNE.

 

It would be nice to see all the dyno sheets overlayed. A bunch of those cams need compression to work and the peak numbers don't mean chit.

 

There speaks a man with a torque curve that matters! I agree that overlayed curves would be interesting.

 

I couldn't AGREE more with you. He is working on getting everything showing where and when!

I posted this to show folks who were thinking about a certain cam as a base discussion. Without doing anything other then what was mention above.

Have the Andrews 57 in my Road King and the 37 was just put in my Road Glide which I picked up yesterday. I need to go for a ride!!!!!

 

some pretty impressive numbers with stock heads but nice comparison.

 

thanks Yellow Man.. I will be following this as I have a '15 CVO SG and would love to ad cams

 

Every one of these would benefit from compression except the S&S551 which is pretty far advanced and low duration. This is a 110 so need to back off some for 103. I think the stock cam is the 255 also. Some of these are not necessarily what I call a drop in. I have told lots of folks there is no magic in a certain cam. Stock motor same exhaust and they are all very evenly matched. The ones that are not bolt ins would come on way late. the bolt ins are pretty evenly matched. The magic is in the combination. Heads, Intake, compression, cubic inches, and exhaust. Most of all is the quality of the tune. Best combination in the world won't work without good map/tune.

 

I TOOK IT UPON MYSELF TO MAKE A WIGGLY LINE CAM CURVE. THIS SHOULD BETTER REPRESENT THE CURVE.
