EXAMPLE:
There are 3 basic spec engine we want to try 50mm, 60mm, 70mm, to all three have a different number in order to know the difference and compare the obtained overall percentage obtained from three spec engine to TSB
The formula to calculate the CC / cylinder capacity
pi / 4 * bore ^ 2 * stroke / could be the other way
1 If the standard spec is bore x stroke = 50mm x 50mm = 98 cc
Let us count if after a stroke bore up and up by 1mm
* If in Stroke up
Bore x stroke = 50mm x 51mm = 100 cc
(can be from 4 / 3.14 x 5.0 x 5.0 x 5.1 = 100 caption: the size of the bore and stroke mm made in cm)
* If in the bore up
Bore x stroke = 51mm x 50mm = 102 cc
(can be from 4 / 3.14 x 5.1 x 5.1 x 5.0 = 102 caption: the size of the bore and stroke mm made in cm)
of the above data it can be seen where the bigger gains with 1mm numbers .... let us make% difference of the increase
Stroke increased from 98cc up into a 100cc or up 2% capacity
Bore up has increased from 98 cc to 102cc, up 4% capacity
Increase in% of this truth we should test again if this is true ... the base rate calculation using a different spec .... if earlier than 50mm x 50mm spec basik try now of 60 mm x 60mm .... if there will be her figure% difference when different numbers of basic spec .....
2 If the standard spec is bore x stroke = 60mm x 60mm = 169 cc
Let us count if after a stroke bore up and up by 1mm
* If in Stroke up
Bore x stroke = 60mm x 61mm = 172 cc
(can be from 4 / 3.14 x 6.0 x 6.0 x 6.1 = 172 caption: the size of the bore and stroke mm made in cm)
* If in the bore up
Bore x stroke = 61mm x 60mm = 175 cc
(can be from 4 / 3.14 x 6.1 x 6.1 x 6.0 = 175 caption: the size of the bore and stroke mm made in cm)
Stroke ups increased from 169cc into 172cc or up 2% capacity
Bore up increased from 169 cc to 175cc, up 3% capacity (the bore up to 61mm x 60mm basic specification has decreased 1%)
3 If the standard spec is bore x stroke = 70mm x 70mm = 269 cc
Let us count if after a stroke bore up and up by 1mm
* If in Stroke up
Bore x stroke = 70mm x 71mm = 274 cc
(can be from 4 / 3.14 x 6.0 x 6.0 x 6.1 = 274 caption: the size of the bore and stroke mm made in cm)
* If in the bore up
Bore x stroke = 71mm x 70mm = 277 cc
(can be from 4 / 3.14 x 7.1 x 7.1 x 7.0 = 277 caption: the size of the bore and stroke mm made in cm
Stroke ups increased from 269cc into 274cc or up 2% capacity
Bore up increased from 269 cc to 277cc, up 3% capacity (the bore up to 71mm x 70mm sepk basik decreased 1% in bandimh with the first base spec)
from here we can conclude that the temporary increase in capacity can not peg the figure to die, but we can use the average anggka.
so the above calculation Bore step up is the fastest step to increase capacity
with the difference in% per 1mm is:
Bore up can increase the capacity of as much as 3-4% (with 1mm)
while receipts up an average of 1.5 -2% (With 1mm) Hopefully with this review friends can take into account the back which is more prioritized bore up or receipt up.
Note: For up stroke 1mm in use here is the total value obtained from 0,5x0,5 = 1mm
