Seriously considering this upgrade path for my 17' M2.
A few questions...how much power do you think the stock downpipe/catalytic converter rob from this power band? Would it be seen as a requirement to use a high flow cat? I'm running CA 91 octane as well, so I know I'm already limited but everything is relative. That said, I don't want to go through the hassle of upgrading the fueling system and want to keep this simple i.e. no meth, upgraded HPFP, PI Thanks for being so detailed with your experiences. -Mark |

Easy a little bit. CA 91 can't max out stock turbo even if you run rich with bigger pump. You will want to reconsider the turbo upgrade idea. Also the stock dp holds up well up to 17-18psi up top (however high boost down low doesn't matter). Stock is good actually, power wise. However if you push hard (don't think any kind of street drive or even spiritual B road is pushing hard), you need dp for heat dissipation. Sean

Without Ethanol or meth, it would be difficult. FBO PS2 can achieve that peak power, at too much cost of low end for just 400whp. Alternatively TTE460 is good and stock responsive, literally meeting the specification. However, at 400whp, it's really the octane that's limiting the upper end. The turbo seems to work fine there. I'd stick to stock and make a healthy 370-380.
