Active Autowerke Gen2 Level3 dyno day
Had 8 cars at 5252 Motorsports in Victoria, BC for a full day on the dyno.
1 2010 E92 M3(seen in vid and all data related to this M) 3 AA sc E46 M3's, 1 E46 M3(10lb flywheel, aa headers, KN cais, AA underdrive pulley, AA tune.) 1 2013 E92 M3 Bolt ons, 1 2007 E92 335is(downpipes, cais, AA full exhaust, dinan software) 1 E39 M5 ( AA cais, AA tune) More data on other cars to come. It was a good day of surprises and finding where some more power can be squeezed out of a couple of the E46's. Last edited by schnell325; 03-07-2014 at 04:20 PM.. |

That sounds right. Dynojet vs Dyno dynamics with eddy current
Correction: Have verified with the owner of 5252 that the dyno dynamics is corrected to read exactly as dynojet. The showing of Flywheel HP is how his software is set. The reading is WHP. |

LOL This is WHP. Here is the company that did the dyno. Read some of the blogs to see this is how their dyno is setup. http://5252motorsports.blogspot.ca/ http://www.5252motorsports.com/page9.html

Dyno dynamics can display estimated flywheel power, it just multiplies the measured wheel hp by some predetermined amount.
It's not wheel hp when it says flywheel right on the graph. |

Whether thats wheel or flywheel power, still big numbers! Car sounds wicked on the dyno.
Are those temperature readings accurate though? Ambient temp of 70ºF but IAT of 53ºF?

This explains why last year it ran 591whp on this dyno around the same time Active dynoed their car, blitz, on a dynojet and it was 586whp. The difference this time was IAT's, that's all. Makes a huge short difference. Regardless the numbers were put down. It did multiple mid 590's-600runs through the day as well.

The VT3 is a low compression and takes more PSI to make same power.
The power drops close to redline because Active Autowerke keep BMW's Revlimiter strategy. BMW starts closing the throttles blades as it coming up to redline. Doing this helps the engine not slam into the limiter. Some tuner companies do away with this strategy and keep them open right to the limiter. This can gain 15-20whp but you are slamming the limiter and it can be hard on the engine and the blower. You can see the throttles start closing in the video on the final run. also this car has a 8100rpm redline why does power drop off at about 7700rpm the car makes about 8.5psi there……..boost keeps climbing but power just drops off……..

But I will comment about Dynojet vs. Dyno Dynamics. The difference is usually about 11%. You can see in the upper right there is a field that says "Extra corr: 1.000" -- that means there is no extra correction being applied. That makes sense because in flywheel mode, you wouldn't want any extra correction applied. Another thing that caught my eye was the dyno correction factor. They are using J1995 instead of J1349 correction. That's a bit odd...but doesn't mean anything other than that. J1349 is the standard most people use. So let me translate that for you and give you the numbers in all the various correction factors. Car-1: Unc: 643.6 hp, 437.9 tq (uncorrected) SAE: 628.5 hp, 427.6 tq (SAE-J1349) STD: 645.5 hp, 439.2 tq (STD/STP) J1995: 632.0 hp, 430.0 tq Car-2: Unc: 628.6 hp, 426.1 tq (uncorrected) SAE: 613.4 hp, 415.8 tq (SAE-J1349) STD: 630.1 hp, 427.1 tq (STD/STP) J1995: 616.7 hp, 418.0 tq |
