My friend Raymond, and Lotus owner extraordinaire, brought by his recently finished Europa S2, an early 54 with French door mechanicals. It was very interesting driving it back to back with my S1. My S1 is much more noisy, by an order of magnitude. Even talking inside the S1 when it isn't even running sounds like you are in an echo chamber compared to his more robustly upholstered S2. The other thing was how strong his engine was with a 45DCOE and a 4 into 2 header. Mine, not that wildly tuned, may have been more powerful, but not by that much. I'll post more later as I have to run now...
