Formula (is this correct?): Bore X Bore X Stroke X .787 = Displacement (Note: all numbers in centimeters NOT millimeters.)

Bore: Bore: Stroke: Multiplier: Displacement= Kit: Supplier:
10 10 8.3 .787 653.2 Stock Stock
10.2 10.2 8.3 .787 679.6 2mm larger bore Pami, TVI
10.2 10.2 8.6 .787 704.2 2mm bore + 3mm stroke Pami 703
10.3 10.3 8.8 .787 734.7 +3mm bore + 5mm stroke (old SamCoe 733??)
10.55 10.55 8.6 .787 762.1 5.5mm + bore + 4mm stroke Pami 760
10.55 10.55 8.7 .787 770.8 +5.5mm bore & +5mm stroke TVI 770???
10.5 10.5 8.3 .787 720.2 5mm + bore TVI / (old SamCoe)
10.85 10.85 9 .787 833.8 +8.5mm Bore & +7mm stroke Pami 830
10.55 10.55 8.3 .787 727 +5.5mm bore Mr HP new jug
10.55 10.55 9.1 .787 797.1 +5.5mm bore + 8mm stroke Is this the Mr HP 800 kit????

Is this correct?

Is this the TVI 770?
Is this the Mr. HP 800kit?

 

bore X bore X stroke X # of cylinders= displacment
I have a handy displacment calculator that runs in Excel only 5.5 kb already setup default for banshee and 250R space 2 & 3 but has 30 spaces total, you can plug any figures you want in there and it will calculate it easy as pie [img]i/expressions/face-icon-small-smile.gif[/img] PM me a Email addy if you want it

 

Spacing got real messed up on my post.

10 X 10 X 8.3 X .787 = 653.
Bore X Bore X Stroke X .787 = displacement for the DS

First number is bore, second is bore, third is stroke, fourth is multiplier, fifth is what the displacement is and sisth is the kit.

 

Maybe that works too, in this calculator I have it's
bore X bore X stroke X # of cylinders
100 X 100 X 83 X 1 = 651.882 (according to this calculator I have)
My service manuel specs displacment at 652

or [img]i/expressions/face-icon-small-smile.gif[/img]

105.5 X 105.5 X 87 X 1 =760.5277565 [img]i/expressions/face-icon-small-happy.gif[/img]

I don't know I think it's right, [img]i/expressions/face-icon-small-smile.gif[/img] but then I don't build engines

 

Sounds like your spreadsheet is correct but, there must be a "factor" in there (like the .787 I have).

Otherwise, 100 X 100 X 83 X 1 = 830,000 [img]i/expressions/face-icon-small-shocked.gif[/img]

Someone has to know what the Mr. HP stroke on his kit is. . . is that correct?

 

MisterHP stroker is +8mm

 

eh hehe [img]i/expressions/face-icon-small-blush.gif[/img] this is what happens when you post in a hurry without even thinking, the factor is .0007854 (in this calculator)
sorry [img]i/expressions/face-icon-small-blush.gif[/img]

 

Punch this into your calc...works for everything and everytime.

Bore x Bore x Stroke x # of cyl`s x .7854 / 1000 = CC

( / ) = Divided by.

If you feed in bore and stroke in mm divide by 1000. If your bore and stroke are in centimeters do NOT divide by 1000.
