So the heartbreaker lived up to its name this round...
4 runs with the best being the first at 536 WHP and dropping 40 WHP from there (4th run didn't record).
The blue lines are the important ones. Temps were chilly/ideal @ 47 degrees in the cell with their 60 mph artificial wind/blower as well!
Boost was 9.5-11 PSI throughout the run on the OEM sized pulley.
We do note an anomaly at 4000 rpm...ECU switching to low octane map (dropping 4 degrees of ignition timing) even though no knock was detected. Ted Jannetty confirmed the tune is conservative and we've already received an updated program to load which should address both areas. Unfortunate part is temps are below freezing with snow on the ground here in Stuttgart so it will be March before we can revisit the truth machine. ;-)
Overall, the engine appears solid with 4 runs to 7000 rpm limiter, sounded great doing it, and nearly drives like OEM thanks to Ted's efforts! Incredible feeling to have such a homebuilt project come together and survive the dyno - just means we get to do again in the spring with more to be had! (536 WHP = ~650 CHP)
