Well here is a dyno of the Werk's B5 stock vs modded on the 2013 pipe.....

Explain the different lines please..why are there 4 when you only compared stock to modded? what does each colored line represent?

Maximo

iTrader: (11)

The top two lines represent HP, the bottom two lines represent torque...

stock Mod
1.38 HP vs 1.84 HP
57.91 oz/in vs 72.43 oz/in

Here is a short video of the dyno... For anyone curious it is a custom made dyno using the Datamite Pro hardware

what is the difference between horsepower and torque? And what are the numbers going up the left side of the column?

Maximo

iTrader: (11)

the column on the left represents a scale... the torque curve and HP curve are plotted against it..... to read it accurately you need to move the decimal to the left 1 point...where it says 10.0 it is actually representing 1.00

The engine gained .46 HP and 14.52 oz/in...

that is darn impressive neil. Do you find a better gain in performance modding a werks vs a picco?

Maximo

iTrader: (11)

Hard to say really, each engine has different characteristics they bring to the table...In peak gains I have seen more from the Werk's, but the Picco gains a much better curve over stock with the modifications...So it really depends on what your looking for....

Horsepower is how fast you get to the Wall. Torque is how far you push it.

Nice work on the dyno Neal!! You may get flack for it not being a X-dyno but for personal testing, who cares. It looks like it will work well for you as it shows the modifications do make improvements over the stocker. The actual numbers may vary a little from dyno to dyno which is expected but at least you now have a good measuring stick

this motor is already a beast your modded one must be absurd

I will be posting as many stock engine dyno results as possible.... Even tho its not a X-Dyno it uses the same software/hardware...just a newer version.... Next is the mighty Picco 28 !

Thanks for the compliments Mark... it was a big project and took quite some time to get it all dialed ..I am hoping to have an engine tested on a X-Dyno and have it compared to my own very soon...

Its a total blast to drive ! sounds insane on the 2013...if i make a pass too close to the video camera it shuts my camera down for a split second....

Here is a video of the engine in action...we were taking it easy fo the most part as it was only tank #2..still ripped hard tho...

Lookin good Neal. I know how much time and
hard work you put in just to get to post that
dyno graph. Not to mention how much time you
got screwed out of by the guy who just couldn't
deliver on the other dyno.
I would like to have a hand in getting a dyno graph
on a Clocked Racing Engines RB C6 posted in the near
future. (Hint-Hint)

Dreaux, the formal difference between torque and HP is this:

Torque = amount of work being performed (lb-ft) Ex. the work needed to push 1lb. a distance of 1 ft.
HP = rate at which that work is performed (work/time). Ex. pushing 1lb. a distance of 1 ft. in 1 min.

For further clarification, HP is actually a function of torque (1HP = approx. 33,000 lb-ft/min)... and no, that's not a typo. It really is 33,000 lb-ft.

The formula for converting between HP and torque is (HP = Torque X RPM / 5252). The 5252 is a conversion factor to get the units matched properly, and to change the time variable into RPM.

I always like looking at dyno curves for full size engines and making sure the HP and torque lines cross at 5250 RPM. If not, then the company advertising that engine likely messed with the scale on one of the curves to make it look more attractive (gotta love unscrupulous advertising folks). Since the nitro motors run at such high RPM, and make such small numbers, you probably have to jack with the scales on both curves to make them readable, so I'm not sure if they'll still cross at 5252.

Anyway, I know this was off topic a bit, but as you can see, the "how fast you hit the wall, vs. how far you push it" analogy is actually quite accurate.
