PMILLER Posted March 9, 2017 Report Share Posted March 9, 2017 I CHANGED THE CAMS ON MY 3SGE, GEN 3 TO HKS 264. I HAVE DEGREED THESE CAN CAMS BUT WHAT SHOULD I MONITOR TO CHECK THAT THEY ARE OPTIMISED. Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted March 9, 2017 Report Share Posted March 9, 2017 The only real way to see that they are "optimized" is to put the car on a chassis dyno and move the cams about while tuning.Granted, there will always be some compromise when setting cams on a non vvt motor.

PMILLER Posted March 10, 2017 Author Report Share Posted March 10, 2017 Thanks. I suspected as much Quote Link to comment Share on other sites More sharing options...
Davidv Posted March 10, 2017 Report Share Posted March 10, 2017 (edited) Hey there, I ran some tests on a VVTI motor by connecting up a MAF sensor, and then datalogging the output at varying cam advance angles. As per below. So it should be fairly easy to see where it's adding airflow (power potential!) without a dyno by looking where you need to add/remove fuel to reach goal AFRs at differening cam angles.(Then head to dyno to optimise ignition timing etc) Edited March 10, 2017 by Davidv b3tuning 1 Quote Link to comment Share on other sites More sharing options...
