Won't work for everybody
the high CR is ok for in town and short bursts, but try to race up a mountain pass with your 10-1 and let me know how it goes.
knock knock, rattle rattle
who's there?
it's your rings and rod bearings, they have some complaints |

Actually talked to my buddy Raymond about a little 1835 he built for a guy named Ray Hulvey.....10:1 compression ratio and dude drives it everywhere.....drives the shit out of it ........daily........and has been for over a year......it still runs strong.......Berg was a great innovator and basically the grandfather of the hot rod VW scene, but he was a bit full of shit when it came to compression ratio......or maybe just a tad closed minded ......anyway, its not being built to last forever .....being built for fun

It can be done you just have to pay attention.
As it is now I run mid grade gas at 9-1 even, then if the temp goes over 80 and the humidity goes under 20% I just fill with premium gas before getting on the highway.
I used to adjust the timing a lot, now I leave the timing alone and adjust the gas 
I never seen an engle 140, only heard they exsit  whatever duration it has I bet it wants 9.5-1 at the least |

Berg's opinions on compression ratios were formed at a time when the composition (and quality) of gas was changing rapidly. His recommendations were for customers that expected stock life from modified motors and yes, he erred on the side of caution. You have to remember this is a guy that got some 140,000 miles on his own 138hp bus motor.
Yes, higher cr in your beast will give more power, but as you say, it won't last forever. And if you push the limits hard enough it won't be a drive any where beast at the drop of a hat either. It's all about what you want...

I don't think the humidity ever drops below 20% here in GA........

Exactly! Nah.....won't be abusing the motor.....will get pushed at the track on a every now and then basis but will be driven smoothly most of them time...and at freeway travel I'll be sensible.....no screaming down the highway at 80 MPH for me....just occasional bursts of speed, nothing for extended periods.....65 Mon on the nose is just fine for me....should keep fan speed at the sweet spot......CRAP....SHIT.....I CAN'T WAIT TO BE CRUISING IT AROUND!
