Interesting results recently at the 034 dyno day in California. A bunch of cars dyno’d, ranging from older Audis to newer…small engines to 4.2 and 4.2 SC cars. The results? Pretty much impossible to find. Wonder why?
Because the dyno is a heartbreaker and everyone is burying the results.
We heard about the JHM stage 1 supercharged car that is making 6 psi of boost, non-intercooled. Why did we hear? Because JasonAMD the retard decided it was bad news for JHM and thought he would yell it out on all the forums for everyone to hear. But was it really bad news? Or do we need some context to better understand the numbers?
Let’s see…what do we know?
BenSTi dyno’d 328 whp with his 2.75" catless exhaust. This alone is interesting because a quick look at Ben’s signature on audizoo reveals 355WHP 298WTQ on stock tune/91Oct. It’s very interesting in fact, because Ben dyno’d those numbers at 034 motorsports as well. Any change since then? Same car, same engine, healthy, same modlist. BUT…034 got a new dyno. interesting to see that Ben hasn’t updated his dyno numbers in his forums signature. Guess he’s living in the past with the old 034 numbers 
Hmmm…so same setup as before, and now he dyno’d 328 whp as his best. So he dyno’d about 8.2% higher on the old 034 dyno. Pretty significant. Guess the new dyno is just a tough dyno. The old one was pretty much right in the middle of the range of what we saw from dynojets and mustang dynos properly calibrated. It was a Land-And-Sea. Of course everyone noticed this and made a point to explain this might be why some of the cars on the new dyno put up modest numbers, right?
Nope.
The JHM stage 1 SC car owned by Denis also dyno’d that day. Denis has a CATTED exhaust made by ebwerks. Same exhaust as Ben, but I believe Denis is catted and Ben is catless. As we know the cats can choke an NA RS4 of about 20 whp, so keep that in mind. The JHM stage 1 car was non-intercooled as well, so sitting stationary on a dyno pushing boosted air into the motor isn’t ideal for measuring power, but let’s humour ourselves. The JHM stage 1 car dyno’d 389 WHP. Definitely not awesome, but about 61 whp more than a catless full exhaust RS4.
If we apply that same ‘loss’ to what Ben lost from the old dyno to the new dyno, we see the JHM car’s 389 whp number turns into 421 WHP. If we knock the cats out, I wouldn’t be surprised to see 440 whp or so. Basically exactly what we’d expect from barely 6 psi, non0intercooled in a hot dyno room in California, sucking down dyno room air rather than free flowing air while the car is on the road going 100 mph.
There was an RS5 there that dyno’d 315 WHP I believe. Someone might confirm that. We have seen RS5s dyno around 340-350 whp stock at other shops pretty regularly. What does 315 whp turn into when you add 8.2%? 340 whp, not surprisingly.
So what’s the bottom line/moral of the story? The moral of the story is that the dyno doesn’t really help a consumer purchase a product…it’s a good tool for a tuner maybe, but for us? It will just paint a muddy picture. If those two Rs4s with a modest 61 whp difference were to line up at a dragstrip in the real worl in good conditions with good drivers Ben’s car would maybe run 12.5 @ 111 and the JHM stage 1 car would run 11.6-11.8 @ 117-118. This would mean about 7-9 car lengths between them at the finish line…and if they kept going that would turn into dozens of bus lengths. Much more interesting to me as a consumer.
