[s-cars] Question about compression ratios and tuning - More 20vt

[Mihnea Cotet]

Nope, ADU is 9:1, I can't remember where I've read it but I'm sure it has. 
My previous example of an ABY running everything ADU except for the head 
gasket and having to run a few degrees less timing advance is 
self-speaking, I've BTDT several times, on ABYs and AANs.

HTH,

Mihnea
