I'm sure all of you have seen my build thread, I wanted to make a dedicated thread to post the overall results and create a place to log future measurements.
Mod Overview
2002 Porsche 996TT X50
Stock Motor
Stock X50 Intercoolers
Undercover upgrade k24/20G turbos
ProEFI 128 - Tuned by Garth @ Undercover Performance
Undercover "budget" fuel system upgrade w/ E85 support
Brilliant mate, remarkable a stock engine built for 450 bhp can hit and hold 900-950 bhp with new tuning techniques.
A+
Did you check AFRs on the E70 mix.... my winter blend out here is 68% - 72% and I run very rich and get a massive 11 mpg... I would be interested to see what lambdas the ProEFI is able to squeeze on each level of ethanol

Ive always read that 700whp was the limit for the stock internals. Myth? Or borrowed time?
so many factors to consider. since these aren't new motors everything that was done prior to getting to this level enters into the equation. safe to say its the torque not the hp you have to worry about.
