Ok, so after nearly 3 years of owning my truck I finally was able to get it on a dyno, which happens to be a Mustang dyno. At the college I go to we're in the middle of our performance module, so my truck was going to be the first one on the dyno.

Truck: "Tiny Tank" 2006 Nissan SE 4X4 6 spd w/ 49,579km @ time of dyno

Mods:

Volant CAI
Flowmaster 50 Series SUV DI/DO 2.25" exhaust
2* Timing Advance
WRP Crank Pulley
265/70/16 Motomaster A/T tires

Now the results I achieved I am more then happy with! On my second dyno run, with about 45 mins after my first run I put out 251hp @ 5300 RPM and 272 ft/lbs of torque @ 3200 RPM! This was weather corrected of course. The non-weather corrected numbers for that run are 225hp and 245ft/lbs. The difference between these two numbers is mainly in the fact that Lethbridge is a good 2500' above sea level. What follows are stat sheet and dyno runs of my warm up run, and 2 solid pulls.

With this scale you can really see how the VVT affects the torque curve

The money shot!

More VVT action...

This run was a little lower most likely due to the fact it was done about 5 mins after the second one with little time for cool down.

Note: all these runs were done with NO modifications done to anything other then what I described above. 3/4 tank of 91 octane fuel, one dirty a$$ Volant air filter, and 100km away from needing an oil change.

Once thing I found very interesting was how the VVT affected where I got my peak torque. One time it was 3200 RPM, next run closer to 4000. All in all though I'm very happy with these results, and it means I've gained roughly 25hp and a little over 30ft/lbs of torque over the same stock configuration.

great results honestly, figuring that the intake add's 10ish and the pulley adds 5ish (wishful thinking?) that would deduce the exhaust adds roughly 10hp and probably 15ish or more ft-lbs if i had to guess. this is all bench racing going off what the manufacturers say their parts gain that have "proven" numbers but you get the drift...

 

[NissanPowerBaby!!!]

Yah definetly. I honestly couldn't care less what the manufacturers say because Volant supposedly gained me 40ft/lbs :thatswck: Obviously it won't do that but it did exactly what I expected it to do, along with all my other mods.

Nice numbers. Just wish there was one standard type of dyno, instead of comparing 3-4 different types. Just curious, why did the pull stop at 5500rpms? You might have gotten a couple more hp beyond that. Maybe not on yours, but its good to check. vq40's can peak higher, sometimes even 6k +. Anyway, getting dynoed is a blast though isn't it .

I think it might show it on my last dyno but my peak power was actually starting to drop a bit. The main issue though was my speed limiter. I hit 108 mph on the dyno speed which is roughly 174 km/h. But because our speedos are 1.5% off that translates to 177 km/h and fuel shutoff was imminent lol. I'd love to get tuned and run her all the way up to 6250, but I honestly don't think that, without cams, I'd get much more top end horsepower.

But you're right I had an absolute blast! I honestly haven't been shaking like that in I don't know HOW many years

 

[rdrfronty]

I forgot about the speed limiter. Thank god thats gone on my truck. Truthfully I think the numbers got a little too "corrected". The numbers are really good for a non-tuned truck. But every truck is different, so who knows, and again congrats on the good runs!

 

[NissanPowerBaby!!!]

I was expecting numbers about 10 lower in each department but who knows I guess. I've heard somewhere that Mustang dynos are a little more "forgiving" then others, but then again we've had some pretty powerful cars on that dyno before not make exagerated numbers. Hell, tomorrow we've got a guy coming in with a 455 in an Olds 442 trying to best his 270hp, 330ft/lb run from last time...

 

[rdrfronty]

It's pretty cool that the Olds doesn't have drastically better numbers than your VQ40. These are pretty strong motors we have.

 

[VoodooSaint]

I'm guessing that your numbers would be a little higher if you were actually moving and letting the scoop on the volant do its work, as opposed to sitting in a shop with minimal air circulation, sweet run tho!

 

[NissanPowerBaby!!!]

They really are! Some more classmates will be dynoing a 2008 Ford F150, a 98 Dodge Ram w/ the 318, a Toyota Mark II w/ the 2JZ and a Toyota Supra with the single turbo 3L I-6 so there's interesting comparisons to come!

The hp/torque curves dont cross at 5250rpms, what gives?

x2, something's not right

 

[Jordo]

^ I saw that too.

 

[xterra hines]

Nice number bro! That's always a good thing when youu get higher numbers theen you expect. You shouldd do a couple pulls on a dynapack. They are more accurate.

 

[NissanPowerBaby!!!]

Look at the scales people...the numbers do cross. The scale for the horespower is lower then torque.

Thanks! I'd like to try it on another dyno but I'm not sure if there's another one in Lethbridge.

Amazes me what they teach (or dont) in college. 5250 RPMS is where they should cross.

 

[Sangster]

ah..i see the scale thing now. Whomever set that dyno up doesn't know what they are doing. If they did, they would match the scales on both sides.

they do cross at 5250 but the scales on the left and right side (TQ and HP) aren't the same.

I dont like that. Must be a ford thing.

 

[Sangster]

it's a software setting the dyno operator hasn't corrected.

That actually made me laugh out loud

I agree it may not be the best way to setup the graph, but it's completely accurate. It just scales it to show the maximum numbers at the very top of each scale. I know it can be setup/scaled differently so next time I get my truck dynoed (perhaps after some new mods) I'll see if I can get a printout of that, as the dyno operator is my teacher whom I have become good friends with. I'm pretty sure he does know what he's been dong as he's been doing this for about 30 years.
