Come on guys lets keep this friendly. Not everyone is going to agree on every subject but it is good to throw in 2 sides to make a discussion.
I just want to add my 2p worths to this subject.
Funny enough I always add abit of extra fuel to the 4th, 5th and 6th cylinder on all the standalones. Most of the time it is 4th – 1%, 5th – 2% and 6th – 3%.
Why you ask?
Ok basically a while back I had a chat with Mark @ Phoenix to see which cylinder was a popular one for chewing a HG or eating a Ring as every engine has its favourites (E.G 3sgte’s like the centre ones due to the intake manifold design, Tested with EGT Probes)
He mentioned that the favourites were normally 5th and 6th as they tend to run hotter at the back.
Now thinking about it, did the Uk Spec’s add a bonnet vent directly above these cylinders to keep these cylinders cooler?
Also 2 of the standalones I map on supra’s have the ability to log each knock sensor on the block and the one at the back is always the one when I pickup any slight pre det through the cans it is 9/10 that sensor which logs to noise.
