OK, here's a fun one for the novice to ponder and you experts to answer:
Why is the factory mechanical CR so low? and for reference, what is the highest mechanical CR that can be physically achieved? assume no octane limitations - I'm just looking for the design limit for the highest CR that can be / has been in a Type 4 engine using available technology. Thanks |

Yup, original OPP with Joe's handwritten instructions, in a box, never installed. He was a great guy. I used Sharpebuilt too, but never FAT.
Your Cali style is nice. You go to a VW show and walk past dozens of engines with slight variations, carburetors or whatever, then come to that Cali and people just stop. It's there, obviously, and it's right, but there's something about it that's wrong.... something wrong there... Crankfire too, very cool. |
