Records Terms & Rules

Do you believe your engine has potential? Try it out semi competitively with others in the community, find the category your engine fits in and follow instructions below. Also refer to this - https://docs.google.com/spreadsheets/d/13jZxAPikibM8fYfcn3M-SOmE3WE\_-02LSYmte39Yj3s/edit?usp=sharing.

For every record that doesn't say otherwise we do NOT allow modified or non LEGO pieces EXCEPT for lubrication (vegetable oil) and paper gaskets.

**Important to note!!!**

If you send in a record where the clip is clearly faked you will be unable to send in records for the coming week, if this happens 3 times you will be fully unable to send in records!

**Reciprocating SVS RPM**

Engine Qualifications:

* Number of Cylinder: any
* Cylinder size: any
* Stroke length: any
* Piston rod length: any
* Other: Must be using the SVS valve system (click here to read about SVS)

Rules & Terms:

Proof must be in video format recorded in 60 FPS in form as a YouTube video or private file sent to one of our record mods for legitimacy testing, this video must include the engine accelerating from zero to the final value. The RPM must be measured with a Tachometer and the monitor with value should be visible during the whole video, and there should also be a clear frame with the final RPM value displayed on the tachometer. If you don't own a tachometer we will verify but it may take longer and if you can't provide enough evidence in form of sound and frame rate we can't pass you, if you do use a tachometer you will get a check mark on the leader-board, so if you have the possibility, please use a tachometer.

**BLVE RPM**

Engine Qualifications:

* Number of Cylinder: any
* Cylinder size: any

* Stroke length: any
* Connecting rod / Piston rod length: 5 studs
* Other: no modified parts (except lubrication), no non LEGO parts included

The engine must be using the butterfly system which essentially means the piston must act like the valve.

**Powerpull Reciprocating**

Engine qualifications:

* Number of Cylinders: any
* Cylinder size: any
* Stroke Length: any
* Connecting rod / Piston rod Length: any
* Other: No modification (except lubrication), no non LEGO parts included.

Rules:

Proof must be in video format recorded in 60 FPS in form as a Youtube video or private file sent to one of our record mods for legitimacy testing, this video must include the whole pull from start to finish with no modifications to the footage.

**Specific Cylinder Records**

Due to single cylinder engines lack of friction they will always come out superior thus rendering other engines obsolete. That's why there is a record for all the different number of cylinders up to 4 collected in one category. The same rules apply for everyone except the number of cylinders which will correspond to a certain subcategory.

Engine Qualifications: (Applies for all)

* Number of Cylinders: Same as the subcategory says!
* Cylinder size: Max size 6x6
* Stroke length: any
* Connecting rod / Piston rod length: any
* Other:

Rules: (Applies for all)

**Single Cylinder Madness (RPM)**

Only one cylinder engines!

**Dual Cylinder Dankness (RPM)**

Only 2 cylinder engines!

**Triple Cylinder Triumph (RPM)**

Only 3 cylinder engines!

**Quadruple Cylinder Quickness (RPM)**

Only 4 Cylinder engines!

**Cam-driven Craziness**

* Cylinder size: Max size 6x6
* Stroke length: any
* Connecting rod / Piston rod length: any
* Other: Valves must be cam driven (read more!)

**"OTHER" RECORDS**

Chategories:

**Piston size**

Engine qualifications:

* Number of Cylinders: 1
* Cylinder size: any
* Stroke length: 4
* Connecting rod / Piston rod length: any
* Other: Try to make it as big as possible, duh ;D

Rules:

Proof must be in video format recorded in 60 FPS in form as a YouTube video or private file sent to one of our record mods for legitimacy testing, this video must include the engine accelerating from 0 to 500 RPM and there must be no cuts in the video. The RPM must be measured with a Tachometer and the monitor with value should be visible during the whole video, if you don't own a tachometer we will verify but it may take longer and if you can't provide enough evidence in form of sound and frame rate we can't pass you, if you do use a tachometer you will get a check mark on the leader-board, so if you have the possibility, please use a tachometer, the piston must be shown without the engine running after or before the running clip, during this phase you need to manually spin the wheel and show that the cylinder indeed does move (we will calculate piston size by multiplying the width and length to get an area, for example 4x4 studs = 16 studs2 )

**Engine Displacement**

Engine qualifications:

* Number of Cylinders: any
* Cylinder size: any
* Stroke length: any
* Connecting rod / Piston rod length: any
* Other: any

Rules:

Proof must be in video format recorded in 60 FPS in form as a YouTube video or private file sent to one of our record mods for legitimacy testing, this video must include the engine accelerating from 0 to 500 RPM and there must be no cuts in the video. The RPM must be measured with a Tachometer and the monitor with value should be visible during the whole video, if you don't own a tachometer we will verify but it may take longer and if you can't provide enough evidence in form of sound and frame rate we can't pass you, if you do use a tachometer you will get a check mark on the leader-board, so if you have the possibility, please use a tachometer, there must be NO cuts in the clip, before or after the clip you must show the piston with its size without it running and you need to spin it manually to show that it does indeed reciprocate, in this clip you also need to show the length of the crank, of course the main goal is to get these 2 values as high as possible.

The way we calculate is:

for this example we will have a 4x4 stud piston and a 4 long stroke, the piston is 4x4 or 16 square studs (162) times the stroke length which was 4 which will result in 64 cubic studs (643).
