600 with 500 miles
We only use crank numbers or engine numbers when we run the engine dyno
Full Race EFR kit on 62/58 turbo options. Turbos are maxed out flowing over 90 lb/min, running only 6 degrees of timing and 20 psi.
Also, the engine is one of our 4.2l strokers, cams, heads done, basically it’s our pretty much nicest optioned engine package. We do this to spool 71/63’s to make full boost by 3000 rpm thru 7600 rpm. That’s white knuckling that wheel at 875 whp let alone over 1000 on 37’s. Coolant spooling and rad, strokers are overachieving our original design and numbers we were targeting by about 8-10% which I’m stoked with.
I’ll also note the last graph is the same kit on another truck that’s stock engine and with another tuner.
We also since switched to the efr 71:63’s and are good for over 1000whp when Trans gets back in from being built.
Notice the curve not just HP difference on the stroker vs stock.
Also note this is the bone stock fuel system so we were stretching it at this point.
