TLDR:

Dude is a DJ out of New York, buys a BR-Z wants it to dominate the quarter mile (stupid car for that purpose right?). Goes to prime motoring in NJ has them do some tuning fabs up some parts he thinks would work:




cuts stuff off the car makes it look fugly so much so reddit r/cars ripped him a new one at one point, gets more bolt ons, throttle body spacers, "power blocks" for the manifold. Gets the car dynoed incorrectly not accounting for the correct weight and immediately causes him to claim he has the most powerful NA E85 powered twin. Does quarter mile as well doesn't prove that, but instead posts up shakey video footage and blurry time slips. All the while getting banned from several facebook groups and antagonizing frs and brzs he sees on the road

Here you go buddy. Another one just for you. This one is good when something that you unintentionally said in a thread suddenly blows up in your face. It's the perfect 'quick escape' GIF.

I need that on speed dial!!!!!!




Watch the memes and off topic guys (shit did I really say that?). Ichi already warned once on here (GO).

Also what is this thing you call work?

Duly noted

As for what the thing called work is - An 8+ hour daily activity that most persons do not enjoy. I hear though that the way to make it enjoyable is to find a hobby that's even worse. On that note, I think I'm going to take up Cobra fighting.

You may have missed the great memeing of Feb 16 2016. It angered the gods!
And it has been on topic. Over, and over, and over again. The same thing repeated in perpetuity

I love my job!

Could someone please explain the "car weight setting" on the dyno that is being discussed?


If understand it right, this would not affect the HP reading, only the TIME it takes to get the roller up to max RPM.


By simulating a heavier car, it should not affect the HP reading at all.
I have stated before that HP can be measured at constant RPM (without any acceleration), so vehicle weight does not get factored into the HP calculation.

I do believe his video shows him doing a sweep test


Types of dynamometer test procedures[edit]

There are essentially 3 types of dynamometer test procedures:

1. Steady state: where the engine is held at a specified RPM (or series of usually sequential RPMs) for a desired amount of time by the variable brake loading as provided by the PAU (power absorber unit). These are performed with brake dynamometers.
2. Sweep test: the engine is tested under a load (i.e. inertia or brake loading), but allowed to "sweep" up in RPM, in a continuous fashion, from a specified lower "starting" RPM to a specified "end" RPM. These tests can be done with inertia or brake dynamometers.
3. Transient test: usually done with AC or DC dynamometers, the engine power and speed are varied throughout the test cycle. Different test cycles are used in different jurisdictions. Chassis test cycles include the US light-duty UDDS, HWFET, US06, SC03, ECE, EUDC, and CD34, while engine test cycles include ETC, HDDTC, HDGTC, WHTC, WHSC, and ED12.

Types of sweep tests[edit]

1. Inertia Sweep: an inertia dyno system provides a fixed inertial mass flywheel and computes the power required to accelerate the flywheel (the load) from the starting to the ending RPM. The actual rotational mass of the engine (or engine and vehicle in the case of a chassis dyno) is not known, and the variability of even the mass of the tires will skew the power results. The inertia value of the flywheel is "fixed", so low-power engines are under load for a much longer time and internal engine temperatures are usually too high by the end of the test, skewing optimal "dyno" tuning settings away from the optimal tuning settings of the outside world. Conversely, high powered engines commonly complete a "4th gear sweep" test in less than 10 seconds, which is not a reliable load condition[citation needed] as compared to operation in the real world. By not providing enough time under load, internal combustion chamber temperatures are unrealistically low and power readings - especially past the power peak - are skewed to the low side.
2. Loaded Sweep, of the brake dyno type, includes:
   1. Simple Fixed Load Sweep: a fixed load - of somewhat less than the output of the engine - is applied during the test. The engine is allowed to accelerate from its starting RPM to its ending RPM, varying at its own acceleration rate, depending on power output at any particular rotational speed. Power is calculated using (rotational speed x torque x constant) + the power required to accelerate the dyno and engine's/vehicle's rotating mass.
   2. Controlled Acceleration Sweep: similar in basic usage as the (above) Simple Fixed Load Sweep Test, but with the addition of active load control that targets a specific rate of acceleration. Commonly, 20fps/ps is used.[by whom?]
3. Controlled Acceleration Rate: the acceleration rate used is controlled from low power to high power engines, and overextension and contraction of "test duration" is avoided, providing more repeatable tests and tuning results.

In every type of sweep test, there remains the issue of potential power reading error due to the variable engine/dyno/vehicle total rotating mass. Many modern computer-controlled brake dyno systems are capable of deriving that "inertial mass" value, so as to eliminate this error.[original research?]
Interestingly, a "sweep test" will almost always be suspect, as many "sweep" users ignore the rotating mass factor, preferring to use a blanket "factor" on every test on every engine or vehicle. Simple inertia dyno systems aren't capable of deriving "inertial mass", and thus are forced to use the same (assumed) inertial mass on every vehicle tested.
Using Steady State testing eliminates the rotating inertial mass error of a sweep test, as there is no acceleration during this type of test.

[fumanchu1]

I can confirm it was a sweep test as the screen says something along control sweep testing or something along those lines somewhere in his video. I assume that refers to a controlled acceleration sweep

There is nothing wrong with discussions, it's just sad when the person on the other end does it to yank your chain. There are plenty of awesome tuning houses out there that make great products. When someone goes around claiming that his Duck-Dynasty-backyard performance and tuning skills simply put them to shame... That's not cool.l:[/QUOTE]

So your upset because my custom parts make more power than the aftermarket? Not sure why this upsets people. Im usually greatful when someone else pioneers something on another platform so instead of trial and error i can just do the same mods and make good power. I spent lots of money to make this power, you dont have to make 3 different headers, and 5 different intakes, you can just buy one from me and know that its one of the best out there cause i already went through all the trouble of testing it

No "stock shit", pepboys, or home depot shit lol. This was all made in house, mandrel bent to my specs and welded by a professional
