Whats an engine CID?

[HKS]

Hey guys
I was going through a webpage which had mentioned how to analyse the best turbocharger for youe engine.

It had a term called engine CID mentioned in it for the calculations.

I couldn't find out what the engine CID was?

Could anyone help me out with this??

Could it be Cubic Inch Displacement? That seems to fit.

[NumberTwo]

To find your engines CID, take the displacement in cc's and multiply by 0.061. That is that one cc=0.061 ci. Or, 1 litre=61 cubic inches.

Example

2,000ccX0.061=122 cid.

Or a 2-litre engine is 122 cid.

Heres a link to a site with various calculators, just scroll down to Auto Math.

Want to do it yourself?

for input in mm.

BxBxSx.7854xC/1000x.061=cid

B=bore, S=Stroke, C=number of cylinders.

Example

89x89x80x.7854x4/1000=1990.765ccx.061=121.437cid

So a 4 cyl with a 89mm bore and a 80mm stroke displaces 1991cc or 121 cid.
