Quadpound Turbo

The common practice of installing twin twin turbos on a 1.0 litre GM engine to substantially increase horsepower. Modification to a twin turbo, compound system by quadrupling the boost this causing the quadpound turbo phenomenon.

My 1999 Chevy Metro couldn’t handle the horsepower draw from the AC unit so I installed a quadpound turbo system to make the luxurious interior more bearable during the summer months.
