This plus, the new JB4's are being developed to tune more in conjunction with timing. They are running more boost, with more timing, on even pump gas and making more power. Adding E85 to the mix will allow even more timing and more boost. BMS (the maker of the JB4) is continually making more and more and more power with these cars. The record stands at 469 rwhp on stock turbos, E85 mix and meth. The cars are down right nasty. The stock block record was just hit a few weeks ago and stands at 725 whp on a mix of pump gas and some 100+ octane fuel with a lot more room to go.

No, the numbers he was talking about where full bolt ons with stock turbo's pushing those power levels. It's the only logical upgrade past bolt ons is to upgrade to larger or reworked turbo's much like the separation between a bolt on car and going to the next level of H/C

I ran a buddies 335i awhile back in the evo. He went 12.4 in his, pretty stout little car.

Last year bmw revised the fuel pump design and issued a recall and extended warranty on the existing prone to issues fuel pumps. Ever since they did that the issues have subsided tremendously to the point where I don't think it should be a buyers concern. I don't think I've heard of any fuel pump failures since these newer pumps came out. Injectors were another issue but bmw issues recalls on those as well.
