| Correct me if i'm wrong but I think the combination of a supercharger and a turbo charger is called a superturbo(?) And headers, the supercharger is basically used to overcome that annoying turbo lag, i.e., the period until the turbo has sufficiently spooled-up. Unless I have misinterpreted your question and what you are really asking is about the workings of superchargers and turbochargers. If yes, there is already a thread existing on this topic, so use our forum's infamous search option!  Godspeed. Alok. Last edited by ghostrider4385 : 2nd June 2006 at 11:46. |

However, the latest update on this is that VW has made a 1.4 liter engine which is both Super & Turbo charged. And I quote from a recent article in EVO magazine: "A turbocharged engine is an obvious way to go, except that without resorting to clever technology - linked twin turbos, or variable geometry, which remains beyond the reach (in a petrol engine) of anything less than the new Porsche 911 Turbo - the driveability is going to suffer, especially at the bottom end. Volkswagen's answer is to use an engine-driven Roots-type blower to supercharge the input to the turbo. The supercharger output is varied, via a blow-off valve, so its maximum boost can be applied from very low engine speeds without blowing the whole thing apart at 6000rpm. In effect, the supercharger is filling in the lower parts of the desired torque curve that the unassisted turbo could not reach. From around 4000rpm, the turbo - well into its stride - does it all. The thing is, why has Volkswagen done it? The answer is efficiency. This is a classic downsizing exercise and it pays the classic downsizing bonus: economy. The Golf GT comes with an official fuel consumption of 38.2mpg, while the equivalent VR5-engined car used to deliver 31.7mpg. If you were simply to drive the car without being told what was under the bonnet, you might guess at a particularly good 16-valve 2-litre. But it isn't; it's a 1.4." You can find the full article here : http://www.autoexpress.co.uk/driven/...n_golf_gt.html Only interest for me is that if they could do the same to the 2.0 GTi engine or the 3.2 R32 engine!! Imagine the 3.2 producing around 380-400 bhp instead of the usual 247 bhp and still being light and fuel efficient!! Now wouldn't that be a motor worth having!

and it will be super fast ? Are you sure what you are talking about? Do you know how complex it is to run a supercharger and a turbo together ? Last time I saw a supercharger and a turbocharger running in a engine was in a Group B rally car by Lancia..I hope you know what Group B rally cars were.. |
