Here is a startup of a built motor with the jun cams so u can listen to the idle. This was done in Germany they are in the process of getting whp numbers check it out!! This is not my car it just gives u an idea of what to look for if ur thinking about getting the cams. My heads are getting more work done then this car has. Props to GTM
