• HPF (Horsepower Freaks) Stage V E46 M3 with Precision 8285 turbo cracks 1000 wheel horsepower

      Here are some dyno graphs from the HPF M3 back on 10/21/2011 with the Precision 8285. The results would have been a bit higher had we run standard rear tires. The rear tires we were running are the big tall heavy 345s on 13" wide wheels. These runs were at 30psi. We were definitely running into a flow restriction in the Steed Speed turbo manifold after 1,000rwhp and we can't run the HPF cast version because it can't be installed in two sections which make it possible to fit the 8285 without removing the engine.

      We're now moving this motor into the drag car and it will have an HPF tubular manifold, so that restriction will be eliminated very soon. As you can see from the dyno graph, smoothing was at zero, all 12 runs were nearly identical showing very consistent results. All runs were done nearly back to back with minor variations in boost and timing.

        1800 ft lb's of torque in the second dyno pull, impressive.

        Yes but that number isn't accurate.

        soooo the SAE numbers probably don't crack the 1000whp mark.

        Look at the power band.. it's only good for a dyno queen.

        yeah, a guy can look at all other hpf graphs and see their uncorrected numbers are significantly higher than SAE. thus, no 1000whp.
