BTW, for all you out there concerned about BMW loosing money on warrentee and wear issues due to the XEDE, just THINK about how many folks who never considered a 330i are now breaking out their checkbooks for the 335i due to the great potential of MODS, baby, MODS! 450 lb ft of torque is ALMOST what a Z06 7 liter V8 makes!  |
Straight 100oct would probably be worth another 30-50lbft of torque since it would allow me to run 15-16psi safely in the low end/midrange and more agressive timing/fuel curves. The turbos dont have the capacity to support much more boost up top so I'd be surpised if we saw much peak power gains. Perhaps 10-15whp-- most of which would come from the fuel/timing tweaks. We'll dig into intercoolers and induction plumbing/piping next to see if we stumble upon any airflow gross restrictions. Fingers crossed...
