AutoSpeed is amongst the largest of modified car websites in the world, with over 3000 articles published since 1999.
If you want to know about aerodynamics, electronics, hands-on skills like welding and metalwork, suspension design, electronic engine management, turbos, superchargers, intercoolers, exhausts, intakes and a whole lot more - well, you've come to the right place.
And we make it all practicable and achievable. Like aerodynamic testing on the road, using both wool tufts and pressure measurement. Like measuring intake flow restriction accurately and for nearly no cost. (Why get rid of the airbox if it has little or no flow restriction?!) Like showing you how you can build your own electronic kits to modify air/fuel ratios, switch things on and off at certain engine revs, and control turbo boost. Source
