Some more discussion on varying results here: ND1 BBR Super 200 - what did you hit on the dyno?
Let us know how much you find out about the car, please, it’ll be interesting. You might like the MX-5 more than you expect. I test drove a supercharged Lotus Elise and picked my MX-5 instead because it felt more fun on the road and was definitely better equipped. The Emira will be a different proposition altogether, I’m sure - a report on that would be welcome, too
