Williams Mog, ran an open Dyno day a few years ago & the original Mogmag did a writeup
They tested a stock 3.7, actual output was 297 bhp, and the tester said there was still a bit more but it hit a 155 mph limiter
I remember that day - it was a good day out!
The SSL 5L rear end does wonders to tame my +8, I suspect the same treatment could help a Roadster.
Or fit the SSL upgrade to a factory 5 link rear - which
some believe could do with improvement.
