“Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

Piston compression height is the distance between the centerline of the pin to the flat part of the top of the piston. It's important to know this number when ordering pistons--especially custom ones- ...

Assuming a properly tuned engine, there are three factors that contribute to poor streetability: long cam duration, high compression ratios, and excessive cruise rpm. Since cam selection is largely ...

You'd think that the pistons listed for a 10.5:1 compression ratio would actually give you 10.5:1. But it's usually not that simple. Perhaps that's why so many four-wheelers have a foggy or incomplete ...
