Mine should be closer to 300 crank on E85. No idea on acceleration - likely sub-5 0-60's. I have quite a bit more rubber than a stock Miata. BTW, the only V8 swap available starts at $50K (plus the car). Given that I already have a V8 Sol, I think this Miata is better suited to doubling the stock hp while adding very little weight. These are tiny cars and are all about handling and balance. I had a 1993 black with red and BBS LE Miata with a Jackson Racing blower that took it from 116 hp to 200 and it was an absolute blast. After driving the Miata, the Sol feels like a big GT car. I will say the charity car is super fun to drive and all it has on it are wheels, tires, exhaust and coilovers. Can't wait to get the engine work next week.
