Time for an update, quite an exciting one too...
My MR2 went back on the dyno today, and achieved 353.6rwkw (470rwhp) on E85!
I couldn't be happier! 
That's all kinds of silly, even some new types.
Whats the power to weight ratio? Can only imagine that's well into proper supercar territory.
OEM brands quote power figures at the engine, which makes it hard to compare.
My car would have almost 600hp if measured at the engine, which gives it a higher power-to-weight ratio than many supercars. Of course a proper supercar would probably have much better performance at low RPM though.
