350 --> 410cc

To calculate the percentage growth in displacement for an engine upgrade from 350 cc to 410 cc, we use the following formula:
Percentage Growth=(Original Displacement New Displacement−Original Displacement)×100
1. Identify the values:

• Original Displacement (V1) = 350 cc
• New Displacement (V2) = 410 cc

2. Calculate the increase in displacement:

ΔV=410 cc−350 cc=60 cc
3. Calculate the percentage growth:

Percentage Growth=(35060)×100≈17.14%
The growth in displacement is approximately 17.14%.

350 ==> 477 (500)

To calculate the percentage growth in displacement for an engine that increases from 350cc to 477cc, we use the following formula:

Percentage Growth=Original Displacement New Displacement−Original Displacement×100
Step-by-step calculation:

1. Find the increase in displacement:
   
   477cc−350cc=127cc
2. Divide the increase by the original displacement:
   
   350127≈0.362857
3. Convert to a percentage:
   
   0.362857×100≈36.29%

The growth in displacement is approximately 36.29%.
