The graph comparing the Rev-up vs. the HR:

Correct me if I'm wrong, so the HR gained about 6lbs/ft of tq and 15hp over the Revup right? But then with some of the dynos I've seen from the Rev-ups + Mrev2 + Spacer it shows significantly more gains than the HR has shown...Tony could you explain? Thanks.

-Bugs (dyno graph noob)

Edit: Maybe because there's more power under the curve? Not sure what's up...

 

So after reading that guys controversiall site, Im curious what is the best way to break in my Z now, hard or easy ?

 

I would like to se the VQ35HR + direct injection just like Toyota did with their 3.5L 2GR-FSE Nissan has the technology and uses it effectively on the VQ25 and makes some amazing numbers in the neighborhood of 250hp. I think there is plenty more to squeeze out of the engine as it is with most engines, but you always have to worry about emissions, reliability and longevity.

 

Direct injection is good, but I hear it is not very good for high-rpm applications....

 

Hey Tony,
Thanks sharing the HR dyno plot. I've been eager to see one (that I can trust) for a while now. Looks impressive indeed ... for a Nissan.

As much as I hate Toyota, their's still the benchmark for a na 3.5L V6. I would love to see you dyno one of those and plot it against the HR.



And now to clear up some misinformation I read earlier ...

The "Flywheel" designation for power and torque by the Dynapack software is technically correct. For that matter, the numbers you get from DynoJet, Dynodynamics, or whichever dyno are also technically "Flywheel" figures minus the drivetrain loss (aka transmission loss).

Do you really think 250 ft-lbs of torque at the rear wheel is able to sufficiently propel a 3300+ lbs. car from 0-60 in under 6 seconds? Try 60+ seconds. The actual torque measured at the rear hub or wheel is many times greater. It has been converted back to the "flywheel" figure via the gear ratio, so the rest of the average Joe can understand it. If anyone's interested in the actual torque measured at the wheel (hub), I'm sure Tony wouldn't mind shedding some light as the Dynapack software does report those too.

The Dynapack software also goes a step further by allowing transmission correction factor (tcf) for actual "flywheel" numbers. However determining transmission loss is tricky at best, so most operators leave it at the default correction factor of 1.0 (no correction).

Hope that helps.

 

Hi guys,

Here it is. The HR 6MT dyno results.

Nice numbers from the MT.. I wonder what they'd be if the dyno was a dynojet.

 

hmm the hp numbers between the 335i and 07 G sedan aren't that far off then... so is it the torque that makes the 335i so much faster?

 

Thanks for the dyno results.

 

dynapack is an Australian dyno. in Australia they call the wheel hubs the flywheel. which is where the dynapack gets the reading from. there is no real way of calculating flywheel hp in our terms unless you pull the motor and put it on a brake dyno.

LoL. I sincerely hope that was a joke. The actual technical explaination is as is (above). Btw, Dynapack is from New Zealand.

 

Thanks for posting but I'll wait till I see a Dynojet plot before coming to conclusions on how much better this motor is.

 

The comparative dyno plot against the REVUP is all you need to know how much better it is.

And its substantially better.

I didn't see the REVUP as being all that much better than the 287 engine but this new engine clearly is. Area under the curve (near the peak) is thick and broad.

It should do quite well on the track.

 

Ok this is the question that i have..
If the 07 come with dual intakes, tubular headers, and true dual exhaust...how much power could the aftermarket parts possibly add?

 

We can't know untill testing is done, but I'm certaint I'll find more on that engine.

 

The new 07 engine is crazy

 

Nice numbers. The area under the curve is very nice.

 

I agree. I rode in a 07 Enth a week after I got my 06 Enth so they are both fresh and I really couldn't tell the difference. Sounded a little deeper but I am perfectly happy with the 06. Guess we'll just have to wait until some hard numbers on the track.

 

yea ,im waiting for the dynojet on this one.

 

Thanks for posting the graphs. Very useful info to be had by looking at the overall trends, not necessarily the specific numbers.

The HR looks solid but I don't see enough to make me want to trade up and incur the additional expense. 03 ftl.
