anyone know

anyone know what it would be called if im bored out to .60(67.5mm)?example like they call a 240

 

[xjma]

It would still be called a blaster!!

 

[stephen12091985]

really?damn i thought it would make it a raptor

it's .060 over. a 240 kit is NOT .040 over, unlike most people think. they have i believe a 72mm bore, whereas you have a 67.5mm bore.

your displacement is:
(pi)(67.5/2)^2 (57)=203972 cu. mm. or 203.972 cc's.

a 240 is .40 over, a .040 is what most people think is a .40 in which case people think they have a 240 kit.

yea i seen that the 240 was 72mm that why i was wondering thanks for the help everyone

A true 240 is .285" over or 7.25mm over, making the bore 73.25mm. .4 over would be 10.17mm over and would make the bore @76mm which would be @258.6cc on a stock stroke(57mm) blaster. The 240 kits come with a 72mm piston and produce 232cc on a stock stroke crank and 245cc with a +3mm crank.

An easy formula to figure displacement is (bore)x(bore)x(stroke)x(.0007854)x(# of cyls)=displacement

or pi times the radius (bore divided by 2) squared times the stroke. my bad on the saying 240 is not .40 over, i ment 40 thou, or .040. i fixed it.
