There is a lot of beautiful eye candy on this thread!
Here is my POLO 4 banger built in 2011. It has 23,000 miles on it now.
The latest ones being built by tuners like Jerry Woods and others are now getting 230 to 250 hp. See the second set of numbers.
The upper graph is of an engine speced close to mine. Mine has had head work done to my 993 heads with titanium valves and the dynoed engine has stock 993 heads. Dean guessed this engine makes maybe another 10 to 15 hp.
I've tried to keep a period look in my 67. Here is a newer vintage look product from Jenvey.
