no graph, but it's around 90 rwhp. I dont know what other mods/ set up were involved besides the big bore.

That is with a shed load of other work!!
I don't think g-force have realise their goal yet of 100rwhp, and that is with a LOT of very impressive work.
A big bore
on its own wouldn't net more than 75rwhp I would think, and a big increase in torque. I want one.

Yes, a shed load of work. Last i heard they had to make a CNC crank and were now starting to break stuff in the gearbox. G-force is basically re-designing the NC motor as they go!

Did I mention we bought a 5 axis CNC milling machine so we can re-design the engine cases next. Well, we bought it for other reasons, but the comment that started it was "Ya know, with a machine like that, we could....."
