Thumbs Up HPF M3 Dyno Graphs - 1010rwhp, 1013rwhp, 1014rwhp and more from 10/21/2011

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.

Nice dyno runs! Can you please post a graph with just the 3 runs over 1000whp overlayed?

would running a tubular manifold help? I think it would flow better.

Good Numbers, but the peak TQ's are way off. You guys are consistent at right around 680-700ft/lbs.

Very consistent though. Your tuner has it deadnuts for about 95% of the dyno run!

yeah, while the above curves look good, and conclusively prove that you guys rocketed well past 1000rwhp, the graph is a little difficult to read with so many overlayed dynos, please exclude the dynos that lost rpm pickup.

Not sure what this says since there is a wide variance. IMO, consistent and repeatable #'s are the key. I would not conclusively consider this a 1000 whp dyno chart.

What are SAE numbers? Im guessing below 1000whp, which is why they arent shown.

It was cold in October so the correction brings the power down. The flow in the turbo manifold runs out at a tad over 1,000rwhp, so we could have run it on a hot day and made over 1,000rwhp SAE.

Chris,

Are you saying this because of the ambient temperature correction?

Who's beating him up?

No need to come to Chris's rescue.....

You don't need to "round up the posse" because were asking constructive questions.

pretty consistant. I personally would rather see 2-3 runs overlay'd as the others said, not bashing. I can see there is tention built up and this is kinda in response to being called out. It sucks when someone says something about your business then everyone questions if its true....

Also it seems as though the runs get a little choppy up top, were these runs done on the okada coils? have you had any issues with these?
