Hi guys,
@ nrphily,
Yep, excellent please post up the results I'm keen to see them, and hoping they agree with the "normal" findings from all the testing done by myself and others on different High Performance cars.
I agree, the longer / more testing will give a better spectrum for data analysis
After I posted yesterday, I was thinking back to my teenage / 20's years when we had Jaguars........ XJ,s and E Types etc, with V12's and how they used to "peel your face" when you opened the hoods on a summer day :grin
And believe me that was long before Electronic Fuel Injection, my first V12 had 4 big Stromberg Carbs :laugh
@ cowboyt
Yep, that says it in a nutshell, very eloquently put......
And yep changing that set of plugs avoided unduly stressing the Coil Packs.
Regards thermal exhaust wrap, it will be an absolute bitch to do properly on a V12, may even require removing the engine..........If you decide to do this, also take a look at having manifolds etc ceramic coated, I've heard that works well too...........
If you have a Turbo motor, you can see the results of Thermal Efficiency on a dyno, and can certainly feel the difference driving the cars :smile
As you rightly say, proper maintenance is the key here, it is just a shame that a hell of a lot of "Professional" Garages are charging car owners for items, and either they don't need all the items or they are not actually fitting these parts. Trouble is it is soooooo difficult over here in the UK to actually get anything done about this.
I have seen it many times, over my 40 odd years in this trade and it just "tars" all Workshops "with the same brush" :frown
I guess, if you've got a good Indie, stick with him, a lot of Main Dealers seem to be the worst, and not just MB, I've only really gotten heavily into Mercedes over the last few years !!
Cheers Dave
