[Closed] Car - Good idea or mechanical stupidity?

WorldClassAccident · 2013-10-04T18:00:22Z

Manufacturers seem to be moving to turbos to get the fuel economy figures without losing the power. I am not a big fan of forced induction based on experience (despite loving my supercharged V8 SLK). I will start with a slightly clichéd description of the options at the moment. Turbo chargers = good power, good economy, driving experience compromised through lag Super charging = good power, constant mechanical drag effecting economy, good driving experience Natural Aspiration = okay power, poorer economy, best engine response Now imagine having an 'always on' turbo charged engine. Still the good economy and power but with normally aspirated like engine response. I know Lancia and VW have done supercharged and turbocharged engine but this is a very mechanically complex system with lots of extra gubbins to fit into the engine bay. What about this then - fit an electric motor into the turbo charger. The electric motor keeps the turbo spinning while it is 'off boost' and can be switched off once the turbo is up to speed. Less weight and complexity that a supercharger and wouldn't need massive batteries (weight) as it would only need to work at low revs. It could even recharge on overrun. Any engineers want to shoot this idea down before I run off to the patent office?

Need a supercharger, turbo charger, etc?

Engine's too small.... 🙂

Gonna start a new thread. "What bike rack/canopy bars for a Tornado GR4?" Needs to stay on at full thrust. 😀

Or another idea to eliminate lag - a compressed air cylinder to ram air into the intake for half a second til you're on boost.
