Would increasing the compression on otherwise stock 999 yield anything worthwhile without a cam swap? Also, has anyone milled 999 heads to increase compression? I'm think that the heads can not be milled that much and higher compression pistons would be the better route.
What's the maximum that they could be milled physically and also what is the amount that they would need to be milled to get say 13:1 or even 14:1 compression. At that high compression would 98 octane be enough (92 m+r with 30% toluene mixed as octane booster)?
