How much is a set and what is the compression ratio?

[Cordoba16vt]

What is the cost of a seto of pistones?

I.

[Wizard-of-OD]

How much is a set and what is the compression ratio?

It was decided to go with a -8cc dish.

An Elring AAN 20V Turbo head gasket has a max bore of 82.2mm and a thickness when fully compressed of 1.6mm = 8.49cc

Vc = 8cc + 44cc + 8.49cc = 60.49

86.4mm STROKE:
81.0mm bore x 86.4mm stroke = 2226.1cc : Vh = 445.20 cc / cylinder
82.0mm bore x 86.4mm stroke = 2281.4cc : Vh = 456.28 cc / cylinder
83.0mm bore x 86.4mm stroke = 2337.4cc : Vh = 467.44 cc / cylinder

Compression Ratio is as follows:
E (compression ratio) = (Vh + Vc) / Vc

82.0mm Bore:
= 456.28 + 60.49 / 60.49
= 8.54 : 1 CR

83.0mm Bore:
= 467.44 + 60.49 / 60.49
= 8.72 : 1 CR

This assumes an 8.49cc volume for the head gasket and a 44cc volume for the cylinder head.

What is the cost of a seto of pistones?

Price remains the same @ $850 USD + whatever the shipping.

As of right now we are down to (2) of the 82mm sets being available. If I have to sacrifice my own 83mm so that someone can have it then I will do that.
