3SGTE Camshaft Test

This test was performed on the CJM Dyno by Ryan (rm2932) and Dave (mister2ownzU).

For the testing on 272 Intake and 264 Exhaust they tried it at HKS degree specs and then what we believe were specs recommended by ChrisK to a MR2OC member for this cam combo of I108 and E112 lobe centerline.

After the test results, Ryan kept with the standard HKS 264/264 combo.

About the wavyness in the graphs... that was a problem with the Profec B, you could watch the psi fluttering up and down 1 psi and hear it in the wastegate dump.

If you download the files you can view the logged A/F and see that it was very consistent after a few runs of tuning each combo.
