Well, I thought I would stat a new thread for this one.
There is always differences in actual output of high spec engines, however, what we saw today, on a roller that I do trust, was a variation of over 10%.. that is A LOT, and poses a question re quality control surely ?. However, in the light of modern manufacturing techniques and robot build, it is unlikey to be a production isuue.
One of the things we are looking into is the cam phasing device, and IF it is operating on all the cars. Trouble is, only test I can see at the mo is on the rollers again, with phasing unplugged v plugged..
any other thoughts or comments. ?
