Regarding Scott's latest post:
I understand the assumptions that are being made [I think], I also understand what the BMEP has to do with what we drive. But, the million dollar question then is: Why is this car so fu*king fast? I know, I know, my ass is not calibrated and all that, but seriously, this has me intrigued. I have ridden in a 5series with the stock RS2 turbo and Stage II, don't know what else if anything was done but this seemed way better. Now, I understand how you can build a motor for short-term, high maintanence life [btdt x 2much]. But, the idiot in me keeps coming back to the egt's. Whatever those numbers do not mean, they do mean the motor is getting plenty of fuel / dense air, no? Now, could you have an over-rich condition and see this? Maybe. I saw [felt] no evidence of that.
Conclusion? Don't have one yet. But, seems like we have exceptional intercooler work / fuel system work, that is a given. Hmmmm. Maybe the turbo ain't what one thinks it is? Back to my think tank I go....
