Hi all
I have been trying to figure out the 1.8 x cubic inch ratio for A class engines? Is there a formula to calculate these numbers?
For example if I had a 376cubic inch engine what size of supercharger would be the maximum size aloud.
Thanks for your time.[/code] |

Doesn't matter the size of supercharger . If your engine is supercharged it would be 1.8 x 376ci which is 676.8 much higher than the 470ci max for A class you would have to run unlimited

It means that if you want to run forced induction in "A" Class which is max 470 ci, either turbo or supercharged, the largest FI size engine you can run can't exceed 470 ci/1.8 = 261.1 cubic inch.
