That's a dynapack too so it's not comparable to other dyno's including the more popular dynojet.

Dynapacks always put out higher numbers...

Is it just me or do the HR's dyno similar HP numbers on Dynapack? I remember seeing two at 280 to 290 HP stock. I hope I'm mistaken.


EDIT: Found the thread I was thinking about. http://g35driver.com/forums/g35-seda...o-results.html

Did anyone notice it has the non-sport wheels? Not 100% sure about the models, but wouldn't that mean it's the 7AT and not the 6MT?? That would definitely affect the dyno reading.

You can get 6MT with or without the optional sport package. There are two trims: BASE and TOURING. Both have 7AT and 6MT as options. Work pwnage... can't see dynos! Blue *****...

I personally don't care much about how much power it makes, but I would definitely compare the DE, REV-UP, HR, and VHR power bands.

Why does it have volks in the first pic but not the second?

Too many unknown details, I'll wait for more reliable dyno's to come out.

this pull was done in 3rd? I guess they selected which ever gear gave them the best results. Results may vary in 4th and 5th (5th I'm assuming is 1:1)

5th is 1:1 on the 6 speed so that would be the correct gear to pull in. This seems a lil bit suspect all around.

I agree with Bryan about this being fishy. Dyno'ing in a lower gear will usually give you higher numbers.

As always, there are too many different ways to do dynos and they're mainly good for testing gains when you slap performance parts on, and that's only true if you come back to the same dyno everytime after each change. They way dynos are done are, to me, like conducting an experiment many different ways to get the results you want rather than the actual.

Yes, but this is a Dynapack, not a Dynojet. Dynapacks, while generally considered more accurate, read about 8%-10% higher than Dynopacks and about 15%-20% higher than Mustang dynos, partially because the drivetrain loss of actually turning the wheels and the losses caused from transferring that power from the tires to the roller are no longer there - I have heard of Dynapacks being calibrated to give Dynojet numbers however. Also, when I say accurate it is not to say that the number it gives is better but rather that the results are more consistently repeatable, giving a better view of how much power you've actually added via mods when you dyno again and when comparing to other cars dynoed at the same place. I believe is the more useful way to use a dyno plot in most cases anyway, given that the day's conditions and calibration of different dynos can result in wildly different numbers even for the same car, make comparing different dyno plots from across the country an inexact science at best.

As part of ensuring accuracy on Dynopacks, you can specify the gear ratio on the car. As a result, technically you could dyno in 2nd gear, the problem would not be so much inflated power numbers as much an erratic graph.

My issue is that if it is calibrated as a normal Dynapack, why is it only making 280? I'd definitely expect at least 300 hp on a Dynapack and hope that this particular one was simply calibrated as a Dynojet in which case 280 would not be too bad.

If I remember right, that's what the G37s are putting down. The Z is rated at 332, the G at 330, so 280's pretty close.

You must have completely missed my rant about Dynapack vs. Dynojets. Yes, if it was a Dynojet, it should be making around 280 hp - not a problem. But given that most dynopacks read 8% to 10% higher, this should be making around 300 at least.

Some of you act like if this motor is brand new. It's been on on the G37 for over a year. And it usually puts down 270-280 rwhp on your typical dynojet.

Usually Dynapacks do read a bit higher than dynojets. But Dynapacks can read lower than dynojets if they are calibrated that way.

I've dyno'd my car at two different shops with two different calibrations on their dynapacks on one of them read 280 rwhp whereas the other one read 255 rwhp. That's with the same exact mods. (The owner claimed their calibration was much more conservative).

Bahaha, these volks have the 350z brakes behind them...



Peep the front wheels....seems as if the volks have dissapeared.
